How much weight do you gain first trimester

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
Gain weight rapidly. This could be a sign of preeclampsia, pregnancy-related high blood pressure, a serious health issue

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.

How much did you gain 90,000 in the first trimester?

Pregnancy

Actually, the whole question. I have a period of 7 weeks - plus two and a half kilos. I don't eat much, I don't eat in the evening. I just began to move less - I have a tone and a threat + I drink a bunch of hormones. I'm wondering if it's water? Well, I couldn’t eat so much - I’ve been following my weight all my life ... I know how many calories I eat 100%. This is generally a lot - to gain 2.5 kilos for this period? nine0011

I'm 17 weeks old and haven't gained a single gram! Although I also drink hormones and do not say that there is physical activity. I rarely walk, but I didn’t eat more with pregnancy.

So I didn't eat anymore! On the contrary, sweets and bread are completely excluded. I don’t understand where the weight comes from. To the fullness of the slope, I lost weight from 90 kg to 70 with a height of 170 cm. I know how difficult it is. Do B sports almost every day!!!! And now it’s impossible ... I’m sitting, dropping crocodile tears ...

B15 weeks gained +3. 5-4kg

10 weeks, gained 0.5-1 kg, but I always have it, usually I don't get better until 12. Well, you are inclined to be overweight, why are you surprised then, the constitution is like that.

I'm first b. I seem to have put on 3 or 4 kg. in the first trimester, but then I was on diets until b., and when I got pregnant I stopped dieting ... in total I gained 21 kg., The doctor scolded that I should have had a maximum of 13 kg. gain, swelled yes ... after the first b. +/-5 kg. stuck tightly, didn’t throw it off) but it didn’t spoil me much, except that I didn’t return to pre-pregnant weight and the size didn’t become S, but M)))
is now pregnant with her second, in the first trimester she gained 1 kg. and this was with toxicosis, there was no vomiting, but odor intolerance was present. therefore, I ate pasta with cheese and fruits ... already +10 ((and the period is 21-22 weeks ... I can’t even imagine how much I’ll gain right now ....... apparently 21 kg., judging by the trend outlined, is not the limit it will be. ...

I don't want to get fat! Otherwise, I will gain all 30 kilos at such a pace

I was also on a diet "before" and tried to lose weight as always. I don't want plus 21 kilos!!! I don't want to

oh well, don't worry about it!!! give birth, feed, sit on buckwheat with boiled turkey and all your kg will quickly fly away)) well, you are a woman, of course you also want to think about beauty.)) , just awful. I'd rather sit on buckwheat with turkey now, perhaps.

In the very first weeks I also gained 1-2 kg, but then toxin came without vomiting, but nausea and lack of appetite did their job - minus 3 kg per month, i.e. has become thinner than it was before B. Now the period is almost 18 weeks, I gained 2.5 kg, i.e. to pre-pregnancy weight plus about 2 kg. So God forbid, of course, but maybe toxicosis will still make its own corrections. It seems to me that it is wrong to restrict food strictly. Exclude sweet, salty, floury, fried, more vegetables and raw and boiled stews, lean meat, any milk porridge, seasonal fruits. Well, as the threat passes - move more. nine0011

you should still consult a doctor. Although there are a lot of vitamins in buckwheat with turkey)) well, fruits))

Yes, I think that the problem is precisely the lack of movement. But they told me to lie down! What kind of movements are there ... I also feel nausea ... And my appetite is not so hot. Thanks for the support.

Yes, I think chicken, turkey and fruit/vegetables are the best, plus sour milk in the morning. especially since I drink vitamin e and folic, I also drink magne b6.

13 weeks -2kg. I also drink hormones and mostly lie down. Dropped out due to toxicity. nine0011

I’m just like you, only without weight loss so far, and they started taking droppers from toxin, otherwise the liver didn’t work at all according to the tests, the bile in the morning is already dark and the urine is bad
13 weeks, I gained 2 kg even before the toxin and that’s it, the doctor here was delighted with the new kg, but he only lingered for 1 day, today everything is still the same

11 weeks, she threw off 3 kg. I am very disposed towards fullness, before B. I went in for sports every day, so sometimes I allowed myself a tasty treat. Now I eat vegetables, meat, fish from a double boiler. Sour milk, fruits. After 7 pm kefir, but I go to bed early. There was no tox, I feel great, so I try to walk a lot, albeit at an unhurried pace ... I will try to gain as little as possible, but how will it work out. I also lost weight at one time, every kilogram went away with a fight. nine0011

Gained nothing at all until 18 weeks

20 weeks. + about 3-4 kg.
I don't want to dial again 18-20

by 12 weeks. I lost 10 kg. 30 weeks, twins

18 weeks so far 0 increase I think because of walking in the evening and at lunchtime, all the same, in winter I moved and walked less. I eat the same way, I even allow myself sweets, although I tried not to eat before. nine0011

In the first trimester, my weight also went into the negative, as I had severe toxicosis, plus I didn’t feel like eating anything, plus a lot of excess weight. The result is now 32 weeks - weight + 2 kg, I myself am in shock, every day I get on the scales, but it does not increase. Although the belly is growing and already just huge. The doctor says that everything is fine, as both ultrasound and CTG are all normal.
Gained 4 kg during the first trimester during my first pregnancy.

— What are the norms of weight gain during pregnancy that doctors are 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. nine0011

— 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 common in 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.
