Weight Gain During Pregnancy: How Much Is Normal?

Written by WebMD Editorial Contributors

In general, you should gain about 2 to 4 pounds during the first 3 months you're pregnant and 1 pound a week during the rest of your pregnancy. If you are expecting twins you should gain 35 to 45 pounds during your pregnancy. This would be an average of 1 ½ pounds per week after the usual weight gain in the first 3 months.

It's especially important to gain the right amount of weight when you're expecting twins because your weight affects the babies' weight. And because twins are often born before the due date, a higher birth weight is important for their health. When carrying twins, you may need between 3,000 and 3,500 calories a day.

Where Does the Extra Weight Go During Pregnancy?

Baby: 8 pounds
Placenta: 2-3 pounds
Amniotic fluid: 2-3 pounds
Breast tissue: 2-3 pounds
Blood supply: 4 pounds
Stored fat for delivery and breastfeeding: 5-9 pounds
Larger uterus: 2-5 pounds
Total: 25-35 pounds

Is It Safe to Lose Weight When Pregnant?

If a woman is very overweight when they get pregnant, their doctor may want them to lose weight. They should only lose weight under their doctor's care. But in most cases, women should not try to lose weight or diet during pregnancy.

How to Gain the Right Amount of Weight During Pregnancy

If your health care provider wants you to gain weight while you're pregnant, try these tips:

Eat five to six small meals every day.
Keep quick, easy snacks on hand, such as nuts, raisins, cheese and crackers, dried fruit, and ice cream or yogurt.
Spread peanut butter on toast, crackers, apples, bananas, or celery. One tablespoon of creamy peanut butter gives you about 100 calories and 7 grams of protein.
Add nonfat powdered milk to mashed potatoes, scrambled eggs, and hot cereal.
Add extras to your meal, such as butter or margarine, cream cheese, gravy, sour cream, and cheese.

What if You Gain Too Much Weight During Pregnancy?

If you have gained more weight than your doctor recommended, talk to your doctor about it. In most cases, you'll want to wait until after delivery to lose weight.

Here are some tips to slow your weight gain:

When eating fast food, choose lower-fat items such as broiled chicken breast sandwich with tomato and lettuce (no sauce or mayonnaise), side salad with low-fat dressing, plain bagels, or a plain baked potato. Avoid foods such as French fries, mozzarella sticks, or breaded chicken patties.
Avoid whole milk products. You need at least four servings of milk products every day. However, using skim, 1%, or 2% milk will greatly reduce the amount of calories and fat you eat. Also, choose low-fat or fat-free cheese or yogurt.
Limit sweet or sugary drinks. Sweetened drinks such as soft drinks, fruit punch, fruit drinks, iced tea, lemonade, or powdered drink mixes have lots of empty calories. Choose water, club soda, or mineral water to skip extra calories.
Don't add salt to foods when cooking. Salt causes you to retain water.
Limit sweets and high-calorie snacks. Cookies, candies, donuts, cakes, syrup, honey, and potato chips have a lot of calories and little nutrition. Try not to eat these foods every day. Instead, try fresh fruit, low-fat yogurt, angel food cake with strawberries, or pretzels as lower-calorie snack and dessert choices.
Use fats in moderation. Fats include cooking oils, margarine, butter, gravy, sauces, mayonnaise, regular salad dressings, sauces, lard, sour cream, and cream cheese. Try lower-fat alternatives.
Cook food the healthy way. Frying foods in oil or butter will add calories and fat. Baking, broiling, grilling, and boiling are healthier preparation methods.
Exercise. Moderate exercise can help burn excess calories. Walking or swimming is usually safe for pregnant women. Ask your health care provider what exercise would be right for you before getting started.

When to Call Your Doctor

Talk to your doctor if you:

Want to know a good target weight gain for you
Think you are gaining too much weight
Are losing weight during the second or third trimester
Have an eating disorder that is keeping you from eating a healthy amount of food
Need help setting a good menu plan to gain a healthy amount of weight

Managing your weight gain during pregnancy: MedlinePlus Medical Encyclopedia

Most women should gain somewhere between 25 and 35 pounds (11.5 to 16 kilograms) during pregnancy. Most will gain 2 to 4 pounds (1 to 2 kilograms) during the first trimester, and then 1 pound (0.5 kilogram) a week for the rest of the pregnancy. The amount of weight gain depends on your situation.

Overweight women need to gain less (15 to 25 pounds or 7 to 11 kilograms or less, depending on their pre-pregnancy weight).
Underweight women will need to gain more (28 to 40 pounds or 13 to 18 kilograms).
You should gain more weight if you are having more than 1 baby. Women having twins need to gain 37 to 54 pounds (16.5 to 24.5 kilograms).

A balanced, nutrient-rich diet, along with exercise, is the basis for a healthy pregnancy. For most pregnant women, the right amount of calories is:

1,800 calories per day in the 1st trimester
2,200 calories per day in the 2nd trimester
2,400 calories per day in the 3rd trimester

Much of the weight that you gain during pregnancy is not fat, but is related to the baby. Here is a breakdown of how 35 pounds (16 kilograms) adds up:

Baby: 8 pounds (3.5 kilograms)
Placenta: 2 to 3 pounds (1 to 1.5 kilograms)
Amniotic fluid: 2 to 3 pounds (1 to 1.5 kilograms)
Breast tissue: 2 to 3 pounds (1 to 1.5 kilograms)
Blood supply: 4 pounds (2 kilograms)
Fat stores: 5 to 9 pounds (2.5 to 4 kilograms)
Uterus growth: 2 to 5 pounds (1 to 2.5 kilograms)

Some women are already overweight when they get pregnant. Other women gain weight too quickly during their pregnancy. Either way, a pregnant woman should not go on a diet or try to lose weight during pregnancy.

It is better to focus on eating the right foods and staying active. If you do not gain enough weight during pregnancy, you and your baby may have problems.

Still, you can make changes in your diet to get the nutrients you need without gaining too much weight. Talk to your health care provider to get help with planning a healthy diet.

Below are some healthy eating tips to help you get started.

Healthy choices:

Fresh fruits and vegetables make good snacks. They are full of vitamins and low in calories and fat.
Eat breads, crackers, and cereals made with whole grains.
Choose reduced-fat dairy products. You need at least 4 servings of milk products every day. However, using skim, 1%, or 2% milk will greatly reduce the amount of calories and fat you eat. Also choose low-fat or fat-free cheese or yogurt.

Foods to avoid:

Naturally sweetened is better than foods and drinks with added sugar or artificial sweeteners.
Food and drinks that list sugar or corn syrup as one of the first ingredients are not good choices.
Many sweetened drinks are high in calories. Read the label and watch out for drinks that are high in sugar. Substitute water for sodas and fruit drinks.
Avoid junk-food snacks, such as chips, candy, cake, cookies, and ice cream. The best way to keep from eating junk food or other unhealthy snacks is to not have these foods in your house.
Go light on fats. Fats include cooking oils, margarine, butter, gravy, sauces, mayonnaise, regular salad dressings, lard, sour cream, and cream cheese. Try the lower-fat versions of these foods.

Eating out:

Knowing the amount of calories, fat, and salt in your food can help you eat healthier.
Most restaurants have menus and nutrition facts on their websites. Use these to plan ahead.
In general, eat at places that offer salads, soups, and vegetables.
Avoid fast food.

Cooking at home:

Prepare meals using low-fat cooking methods.
Avoid fried foods. Frying foods in oil or butter will increase the calories and fat of the meal.
Baking, broiling, grilling, and boiling are healthier, lower-fat methods of cooking.

Exercise:

Moderate exercise, as recommended by your provider, can help burn extra calories.
Walking and swimming are generally safe, effective exercises for pregnant women.
Be sure to talk to your provider before starting an exercise program.

If you have struggled with your weight in the past, it may be hard to accept that it is OK to gain weight now. It is normal to feel anxious as the numbers on the scale edge up.

Keep in mind that you need to gain weight for a healthy pregnancy. The extra pounds will come off after you have had your baby. However, if you gain a lot more weight than is recommended, your baby will also be bigger. That can sometimes lead to problems with delivery. A healthy diet and regular exercise are your best ways to ensure a healthy pregnancy and baby.

Weight category - articles from the specialists of the clinic "Mother and Child"

— What norms of weight gain during pregnancy are doctors guided by today?

- The average increase for all nine months is from 9 to 14 kg. The exact figure depends on many factors, but a sharp deviation in one direction or the other from the norm should be alarming. To calculate the allowable increase, the initial weight of the expectant mother should be taken into account: for example, women of a fragile physique (asthenic type) must gain more than initially obese women. In addition, it is important to consider the trimester of pregnancy.

— How does weight change in different trimesters?

- Weight gain throughout pregnancy is uneven: at the very beginning it is almost imperceptible, increases significantly towards the middle and may begin to decrease two weeks before delivery. In the first trimester, both weight gain and weight loss are considered normal. On average, during this period, the expectant mother is gaining from 1.5 to 2.5 kg. In the second trimester, the baby begins to grow actively and the numbers will be different: about 500 g per week for thin women, no more than 450 g for pregnant women with normal weight and no more than 300 g for full ones. In the third trimester, the weight of the expectant mother should not increase by more than 300 g per week.

— Why do pregnant women gain weight?

- Contrary to popular belief, weight gain is not only due to the mass of a growing baby and body fat - they make up about half of the total figure. For nine months, a woman's uterus increases, the volume of circulating blood and intercellular fluid increases, amniotic fluid and the placenta form.

— Why is excess weight dangerous?

- Rapid weight gain is typical for multiple pregnancies, underweight women and too young mothers whose bodies are still developing. Often it is the result of normal overeating and requires adjustment of the diet. Diets and fasting days (especially the so-called "hungry") during the period of bearing a child are strictly prohibited even if the pregnant woman is overweight. It is very important to ensure that the baby receives all the nutrients, vitamins and trace elements, so you just need to balance your diet accordingly.

Excess weight may occur due to fluid retention, which manifests itself in the form of edema. By the way, this is especially true for working pregnant women: sedentary work provokes stagnation of fluid in the lower extremities and pathological weight gain. In this case, wearing compression stockings, leg exercises and regular walking is recommended.

— Is slow weight gain dangerous, on the contrary?

- Some expectant mothers gain the first kilograms only after the 14th week - usually for petite women who do not have a genetic predisposition to be overweight or women suffering from toxicosis. In the first case, weight gains slowly throughout all nine months, which, if the pregnant woman feels normal, should not cause concern. If we talk about early toxicosis, then by the second trimester the malaise usually disappears, body weight returns to normal and weight gain goes on as usual.

Weekly weight gain chart during pregnancy. weight gain rates

Weight gain during pregnancy is a change in a woman's body weight according to an average standard, which is monitored by a doctor who leads a pregnant woman. During each visit to the doctor, the expectant mother is weighed. Weight monitoring helps you track the progress of your pregnancy. It is important how fast the weight gain goes and in what quantity.

Pregnancy Weight Gain Rate

There is no single reference figure that fits all pregnant women. Weight gain depends on many factors:

pre-pregnancy weight;
from the figure, the structure of the body;
on food quality before and during pregnancy;
on whether it is the first pregnancy or not.

If the pregnancy proceeds well, by the time of delivery the woman recovers by 10-15 kg.

Weight gain distribution Weight in grams

Child	2500-4500
Uterus	1000
Placenta	400-600
Amniotic fluid (1 ml = 1 gram)	800
Breast (increased glandular tissue)	500
Blood volume	1500
Intercellular tissue fluid	1500-2700
Fat	2200-3000

You will not be able to gain only the weight needed for the baby and the placenta, but not accumulate fat. Fat accumulates gradually. If the expectant mother takes vitamins, makes sure that her food is healthy, of high quality, then fat accumulation will be minimal. Pregnancy is not the time to lose weight. At this time, you need to take care of the quality of food.

Moreover, if body weight does not change or weight loss occurs, this is a sign of toxicosis or some kind of pathology. The doctor will also not disregard too much and sudden weight gain: this may be due to a violation of the diet or a symptom of excessive fluid accumulation. There is a weekly weight gain during pregnancy.

These data are compiled in a table used by physicians.

Weekly weight gain during pregnancy: doctor's chart

The rate of weight gain depends on the height and weight of the woman before pregnancy. To know how harmonious your weight change is, you need to know your body mass index (BMI). The doctor conducting the woman's pregnancy measures her height and weight at the first appointment. There are tables for determining BMI, according to which the doctor finds the desired indicator and writes it into the card. Can calculate BMI unaided:

Height in meters is multiplied by itself. With a height of 164 cm = 1.64 m, it will turn out: 1.64 × 1.64 = 2.6896.
Now we divide the body weight in kilograms by the figure obtained. With a weight of 54.2 kg, it will turn out: 54.2: 2.6869 \u003d 20.18.
The resulting BMI is 20.18.

Now you can see how much weight gain a woman should have during pregnancy by weeks.

Table during pregnancy: the norm by week

Weight gains slowly at the beginning of pregnancy. By the end of the first trimester, the weight increases normally by 1-2 kg. In the first trimester, some even lose weight due to toxicosis. From the second trimester, weight is added more intensively: the child is actively growing, and the system that supports him is developing along with him.

Normal weight gain during pregnancy varies by week for underweight women and overweight women. Expectant mothers need to control their weight. The table below is indicative.

Based on these numbers, you can understand whether everything is going according to plan or whether you should pay attention to nutrition and health. It is better to weigh yourself in the morning, before meals.

Grams add up to kilograms, so go to the toilet and weigh yourself without any extra clothes, in your underwear. So the data obtained will be more accurate.

Take care of your health. Walk more, relax. Find more reasons for joy - psychological comfort directly affects the physical state. Do not give in to the blues, follow the emotional background. Fill yourself not with excess food, but with pleasant experiences.

Weekly weight during pregnancy

Every woman needs to monitor her weight, because a beautiful figure is an integral part of an attractive feminine image. But one day there comes a moment when doctors begin to monitor the weight of a woman. And this does not mean at all that she is sick - no, she is just expecting a baby!

Weighing is a mandatory procedure at every visit to the gynecologist. In addition, in order to control weight, the woman herself needs to weigh herself daily. Moreover, this must be done at the same time - in the morning on an empty stomach, and certainly in the same clothes.

The first two months of pregnancy, as a rule, pass without weight gain, because the woman's body is just adapting to its new state. In addition, many expectant mothers during this period suffer from severe toxicosis, and this, on the contrary, can lead to weight loss.

So in the first trimester, the average increase is no more than 1-2 kg (an exception may be women who have previously followed a strict diet, or athletes who are forced to significantly lighten their training program due to pregnancy).

More active weight gain occurs in the second trimester of pregnancy. According to the norms, during this period, a woman should gain 250–300 g of weight weekly. If the body weight of a pregnant woman increases faster, this may be a sign of a serious problem - dropsy of pregnancy, which is accompanied by edema.

How should pregnancy weight gain be calculated? Let's discuss this point, given that normally a woman should gain from 10 to 12 kg for the entire period of pregnancy.

There are several methods by which doctors calculate how much weight a pregnant woman should gain. Moreover, special attention is paid to this parameter precisely in the last months of pregnancy - doctors even have a special scale of average physiological weight gain, designed for the last trimester.

In accordance with this scale, the average weight gain during the week should be no more than 22 g per 10 cm of height. d.

How many kilograms the future mother's body weight will increase is influenced by many factors.

These include:

Age. The older a woman is, the more inclined she is to be overweight.
Initial weight (meaning body weight before pregnancy). The greater was the deficit of body weight before pregnancy, the higher the chances of gaining extra pounds.
Was there early toxicosis. If a woman had severe toxicosis in the first months of pregnancy, then she could lose several kilograms, which then the body begins to replenish at an accelerated pace.
Features of the constitution. Do not forget that some women are prone to thinness, while others are prone to fullness.
Fetal weight. The size and weight of the placenta depends on the weight of the fetus. That is, a woman who is expecting a large child or twins gains more weight than one whose fetus is small.
Increased appetite. Some pregnant women put on a lot of weight just because they cannot contain the increased appetite.

Let's look at a separate example of how the body distributes the kilograms gained by a pregnant woman. So, with an increase of 12 kg, they are distributed as follows:

the weight of the child is 3,300 g;
uterus weight - 900 g;
placenta weight - 400 g;
weight of amniotic fluid - 900 g;
weight of the mammary glands - 500 g;
weight gain due to increased blood volume circulating in the body - 1200 g;
mass of adipose tissue - 2,200 g;
mass of tissue fluid - 2,700 g.
And the total amount is 12.1 kg.

Some pregnant women try to diet to limit their weight gain: some are afraid of gaining too much weight, others are afraid of giving birth to a large baby. That is why it is so important to know what is the rate of weight gain for you personally - this will help you avoid problems and not make mistakes.

Let's calculate the allowable weight gain on our own using Body mass index (BMI index). To do this, you need to know your initial weight and height.

Let's use the formula BMI = weight in kilograms / (height in meters * height in meters).

How to weigh yourself correctly during pregnancy

Doctors do not recommend weighing yourself daily, it is not always informative, fluctuations are not always noticeable, the error is large, and in general this can lead to unnecessary worries. The correct option: control the weight once a week, in the morning, on an empty stomach.
It is important to use the same scales, now the priority is "dynamics". Weigh yourself only at home or in the office of your gynecologist.

Why does weight gain occur?

Excess weight is caused by hormonal changes in the body, which makes the expectant mother constantly feel hungry. Many pregnant women decide that now they need to eat for two. No need.

Just eat twice as good - more varied, more correct, but not more.

And support your body with Elevit vitamins adapted for each of the stages: Elevit Planning and I trimester*, Elevit Pronatal**, which is advisable for women in the second and third trimesters, and Elevit Feeding* after childbirth.

References

* Not a drug. dietary supplement. There are contraindications.

According to the instructions, Elevit Pronatal can be used at the stage of pregnancy planning, during pregnancy, after childbirth and during breastfeeding.

Calculator of BMI and weight gain during pregnancy

Body mass index (BMI), BMI ) is a value that allows you to assess the degree of correspondence between a person’s weight and his height and thereby indirectly evaluate whether the mass is insufficient, normal or excessive. This index is significantly different in men, women and women during pregnancy.

Need this calculator? Write to me at mail@zygar. ru

If a woman had a body weight deficit before conception, then during pregnancy she may gain a little more than normal. While expectant mothers with more expressive forms should add a little less than the norm. A table based on the body mass index before pregnancy will help calculate more accurate indicators.

This table is for mothers with one child:

BMI before pregnancy
How much can you gain during pregnancy

BMI less than 19.8	13-18 kg
BMI from 19.8 to 26	11-16 kg
BMI 26 to 30	7-11 kg
BMI over 30	5-9 kg

What if there are twins? For this case, another table has been developed:

BMI before pregnancy
How many kg can you gain during pregnancy with twins

BMI from 19.8 to 26	17-25 kg
BMI 26 to 30	14-23 kg
BMI over 30	11-19 kg

At different stages of gestation, the rate of weight gain varies. In the first trimester of pregnancy, a woman adds only 1-3 kg. However, with severe toxicosis, the weight can remain at the initial level or even go into minus.

In this case, do not worry, because the decrease in mother's body weight at an early stage does not pose any risks to the child. In the second and third trimesters, the average weekly weight gain is 300-400 grams.

But, again, it is worth noting that this indicator is individual for each woman.

Aleksey Gennadyevich Savitsky, Doctor of Medical Sciences, obstetrician-gynecologist: “Weight gain of 400 grams per week is an absolute norm during pregnancy. But you need to evaluate the picture in general, focusing on the indicators during the month.

Because jumps during the week can be both up and down. In this case, it is necessary to monitor the condition of the woman: the presence of edema, blood pressure, the presence of protein in the urine. All of this needs to be assessed as a whole.

By itself, the weight is a conventionally indicative unit, a criterion for assessing the situation. ”

You can calculate it yourself using the following formula: 22 g is multiplied by the height of the expectant mother, expressed in meters (the comma is thrown back). For example, with a lady's height of 160 cm, the calculation will look like this: 22x16 \u003d 352 g. This is an individual weekly increase in the second and third trimesters of pregnancy. A more generalized table is presented just below:

How the weight of a pregnant woman increases: weekly pregnancy weight gain calculator

During pregnancy, a woman's figure changes, along with this new kilograms come. This should not be feared if weight gain during pregnancy is normal. It is necessary to keep these figures under control so as not to miss some pathologies of pregnant women. In addition, with normal weight, childbirth proceeds without complications. The doctor who observes the woman is obliged to follow this. Additionally, you can find a weekly pregnancy weight gain calculator yourself to fix your weight and know if it is within the norm. Below you can find everything about weight gain during pregnancy by week.

What is body mass index?

Weight during pregnancy increases based on body mass index (hereinafter abbreviated as BMI). What it is? Calculating your BMI is very simple: multiply your height by 2, and then divide your real weight by the result. The final figure is your BMI, evaluate it as follows:

less than 18.5 is below normal;
18.5 - 25 is normal;
25 - 30 are considered redundant;
more than 30 classify as obese.

Important! You need to know your BMI, on the basis of which an individual rate of weight gain during pregnancy is developed.

In addition, it is necessary to take into account the accompanying factors: how old is the woman, whether there was toxicosis in the early stages. If a woman is pregnant with twins or all women in her family are born heroes, then in such cases, weight gain may be higher than normal.

What causes weight gain

Of course, the child himself most of all influences weight gain. On average, children are born weighing 3.3-3.5 kg. The rest of the weight a woman gains by the end of her pregnancy is:

uterus, approx. 900 g;
chest, up to 1.5 kg;
amniotic fluid, on average 900 g;
placenta is 700 g;
extra body fat, more than 3 kg;
intercellular fluid (lymph), up to 1.5 kg;
blood volume increases from 1.5 to 1.8 kg.

After giving birth, most of the weight gained is gone, but the weight does not immediately return to normal, as she needs energy to produce breast milk. What comes with food is not enough, so the body draws it from internal fat reserves.

The Weekly Pregnancy Weight Gain Calculator helps you keep track of your gradual weight gain.

How many kg should be added for the whole pregnancy?

The total weight that can be gained without harm to your health and baby is individual for each woman. Calculation of weight gain during pregnancy occurs in accordance with BMI.

If we summarize these figures, it turns out that: with a low BMI, you can gain up to 18 kg, with a normal one - up to 16 kg. If there are problems with excess weight, then the additional weight will be 12 kg, and those who have a decent excess of BMI can gain no more than 6 kg.

Weight gain up to 21 kg if the woman is expecting twins.

Trimester weight gain

Weekly pregnancy weight gain calculator should not show drastic changes at the very beginning of pregnancy, on the contrary, due to constant bouts of toxicosis, weight can decrease by a couple of kilograms. This should not scare you, because in the second trimester you can easily change the situation for the better. On average, a woman gains 1.5-2 kg by the end of the first trimester.

The second and third trimesters are a time of active growth and development of the fetus, so on average a woman can gain 500-600 g per week. If the numbers exceed this figure, this may indicate hidden edema, polyhydramnios. These are dangerous conditions for both the pregnant woman and the child herself, therefore, in such cases, you need to consult a doctor and possibly undergo treatment in a hospital.

Weekly weight gain rate: table

You can keep track of how kilograms are gradually added if you keep your own schedule and note all changes in it. So you can always understand how much weight you can gain during pregnancy, a table with recorded results helps to maintain constant monitoring. How should she look?

Table: How does the weight of a pregnant woman change by week

Deviations from the norm - why are they dangerous?

The same fears are caused by sharp jumps in weight if the weight stands still or vice versa falls. To avoid all this, you do not need to “eat for two”, as everyone is used to advising expectant mothers. Of course, the nutrition of a pregnant woman should be richer than usual, but nothing more.

The baby will take exactly as much as he needs at this stage of development, and all the extra calories that you eat for him can cause fetal hypoxia or premature wear of the placenta.

For the woman herself, rapid weight gain during pregnancy is dangerous because varicose veins, hypertension, diabetes mellitus or late toxicosis may develop.

Some pregnant women do the opposite, limiting themselves, because they are afraid that after giving birth, extra pounds will remain and it will be difficult to get rid of them. This is a big mistake, since underweight can provoke a miscarriage or the development of intrauterine pathology.

How to control weight during pregnancy

It is necessary to have a weekly pregnancy weight gain calculator handy in order to respond to suspicious changes in time. If you eat right from the very beginning, then there should not be such problems. How should a pregnant woman eat so that the pregnancy weight calculator does not show deviations.

Give preference to natural products. There are no special restrictions, but it is better to forget about sweet pastries, sweet soda and all sorts of high-calorie cakes. This list also includes crackers, chips, cheeseburgers and other fast food.
It is better to eat in small portions 5-6 times a day, so as not to overload the stomach.
If you feel very hungry between meals, you can have a small, light snack in the form of natural yogurt, fruit salad, or cereal with milk.
Despite toxicosis, you need to eat. Let the portions be better than usual, than the stomach will remain empty.
If you're gaining weight quickly, don't try to starve yourself to shed those extra pounds. This is fraught with jumps in blood pressure. It is better to reconsider the diet, eating less saturated fats, which are found in animal products. You can also replace white bread with whole grains and eat less sweets.
Caffeine can interfere with the absorption of folic acid and iron, which are needed for the normal functioning of the fetus, in particular, they help deliver oxygen to the child.
