Does early pregnancy cause heartburn

Indigestion and heartburn in pregnancy

Indigestion, also called heartburn or acid reflux, is common in pregnancy. It can be caused by hormonal changes and the growing baby pressing against your stomach.

You can help ease indigestion and heartburn by making changes to your diet and lifestyle, and there are medicines that are safe to take in pregnancy.

Symptoms of indigestion and heartburn

Symptoms of indigestion and heartburn include:

a burning sensation or pain in the chest
feeling full, heavy or bloated
burping or belching
feeling or being sick
bringing up food

Symptoms usually come on soon after eating or drinking, but there can sometimes be a delay between eating and developing indigestion.

You can get symptoms at any point during your pregnancy, but they are more common from 27 weeks onwards.

Things you can do to help with indigestion and heartburn

Changes to your diet and lifestyle may be enough to control your symptoms, particularly if they are mild.

Eat healthily

You're more likely to get indigestion if you're very full.

If you're pregnant, it may be tempting to eat more than you would normally, but this may not be good for you or your baby.

Change your eating and drinking habits

You may be able to control your indigestion with changes to your eating habits.

It can help to eat small meals often, rather than larger meals 3 times a day, and to not eat within 3 hours of going to bed at night.

Cutting down on drinks containing caffeine, and foods that are rich, spicy or fatty, can also ease symptoms.

Keep upright

Sit up straight when you eat. This will take the pressure off your stomach. Propping your head and shoulders up when you go to bed can stop stomach acid coming up while you sleep.

Stop smoking

Smoking when pregnant can cause indigestion, and can seriously affect the health of you and your unborn baby.

When you smoke, the chemicals you inhale can contribute to your indigestion. These chemicals can cause the ring of muscle at the lower end of your gullet to relax, which allows stomach acid to come back up more easily. This is known as acid reflux.

Smoking also increases the risk of:

your baby being born prematurely (before week 37 of your pregnancy)
your baby being born with a low birthweight
sudden infant death syndrome (SIDS), or "cot death"

There's lots of help available to stop smoking. Talk to your midwife or call the NHS Smokefree helpline on 0300 123 1044. Find out more about stopping smoking in pregnancy.

Avoid alcohol

Drinking alcohol can cause indigestion. During pregnancy, it can also lead to long-term harm to the baby. It's safest to not drink alcohol at all in pregnancy.

When to get medical help

See your midwife or GP if you need help managing your symptoms or if changes to your diet and lifestyle do not work. They may recommend medicine to ease your symptoms.

You should also see your midwife or GP if you have any of the following:

difficulty eating or keeping food down
weight loss
stomach pains

Your midwife or GP may ask about your symptoms and examine you by pressing gently on different areas of your chest and stomach to see whether it's painful.

If you're taking prescription medicines

Speak to your GP if you're taking medicine for another condition, such as antidepressants, and you think it may be making your indigestion worse. They may be able to prescribe an alternative medicine.

Never stop taking a prescribed medicine unless you're advised to do so by your GP or another qualified healthcare professional who's responsible for your care.

Medicines for indigestion and heartburn

Medicines for indigestion and heartburn during pregnancy include:

antacids – to neutralise the acid in your stomach (some are available over the counter from a pharmacist)
alginates – to relieve indigestion caused by acid reflux by stopping the acid in your stomach coming back up your gullet

You may only need to take antacids and alginates when you start getting symptoms. However, your GP may recommend taking them before symptoms come on – for example, before a meal or before bed.

If you're taking iron supplements as well as antacids, do not take them at the same time. Antacids can stop iron from being absorbed by your body.

If antacids and alginates do not improve your symptoms, your GP may prescribe a medicine to reduce the amount of acid in your stomach. 2 that are widely used in pregnancy and not known to be harmful to an unborn baby are:

ranitidine – a tablet you take twice a day
omeprazole – a tablet you take once a day

Causes of indigestion in pregnancy

Symptoms of indigestion come when the acid in your stomach irritates your stomach lining or your gullet. This causes pain and a burning feeling.

When you're pregnant, you're more likely to have indigestion because of:

hormonal changes
the growing baby pressing on your stomach
the muscles between your stomach and gullet relaxing, allowing stomach acid to come back up

You may be more likely to get indigestion in pregnancy if:

you had indigestion before you were pregnant
you've been pregnant before
you're in the later stages of pregnancy

Is Heartburn a Sign of Early Pregnancy?| TUMS

There are so many noticeable changes going on in your body when you’re pregnant. But there are also subtle symptoms of pregnancy you may have before you know you're pregnant. You might be wondering, is heartburn an early pregnancy sign?

Let’s take a look at heartburn and how it might relate to pregnancy symptoms, as well as how to manage some discomfort you might be experiencing.

So, Is Heartburn an Early Sign of Pregnancy?

It is—for some women.

Let’s back up a second and define “heartburn” because, for some women, it might be the first time they’ve experienced this digestive symptom. Heartburn is a term that describes a burning sensation in your chest. You feel heartburn when stomach acid refluxes, or seeps back up, into your esophagus, the part of the digestive track that connects your mouth to your stomach.

While every woman’s body is different, and you can certainly experience heartburn and indigestion without being pregnant, heartburn can occur at any point in a pregnancy¹. So, a woman may experience heartburn as an early pregnancy symptom—even before she knows she’s pregnant.

If you have recently been experiencing symptoms of heartburn and indigestion and think you might be pregnant, see your doctor.

Will I experience heartburn while I am pregnant?

Possibly—and likely. Many women experience heartburn beyond their first trimester of pregnancy². There are a few reasons why:

Hormones relax muscles…

During pregnancy, a rising level of the hormone progesterone relaxes the valve (known as the lower esophageal sphincter) that separate the stomach and esophagus. As a result, stomach acids can flow back into your esophagus² and lead to some of the classic uncomfortable heartburn feelings that come with acid indigestion.

…and slow digestion

Additional hormones slow digestion, which mean food may stay in your stomach longer² and lead to a higher likelihood of acid indigestion.

The uterus crowds other organs

Later, as a pregnancy progresses and the uterus expands, it puts pressure on other organs in the abdomen³—including the stomach.

So, a stomach getting pushed out of place, with the food in it lingering longer, and a valve to the throat that’s a bit looser. The result? Heartburn.

A baby with lots of hair?

You might have heard the old wives’ tale that having heartburn while pregnant means you’ll deliver a baby with a more hair on its head. One small scientific study years ago did find a correlation⁴! Make of that what you will.

Treatment for Heartburn and Acid Indigestion During Early Pregnancy

Before jumping into the possible treatment options for pesky heartburn, confirm you are indeed pregnant with your trusted health care provider. They can help you better understand how to approach your symptoms and decide next steps.

If you are indeed pregnant and experiencing heartburn, we recommend taking the following measures to keep your heartburn symptoms at bay.³

Avoid foods that flare up your symptoms. These might include spicy foods, fried foods or meals, caffeine such as coffee or soda. Create a journal of foods that you’ve noticed might cause upset stomach.
Stay away from large meals just before bedtime. This can trigger acid reflux due to your sleeping position.
Sleep with a pillow wedge that raises your head to deter acid reflux.
Consult with your doctor to determine whether an antacid, like TUMS, would be right for you.

While it’s no fun to experience heartburn and acid indigestion, talk to your care provider about the many tools and resources to help you manage. Whether together you decide you should use TUMS to help manage your symptoms or find comfort in pairing antacids with other preventative measures, you have options.

Heartburn during pregnancy. How to get rid of it?

One of the constant companions of pregnancy (in more than 80% of cases) is an unpleasant burning sensation behind the sternum - heartburn.

The feeling of heartburn occurs when the acidic contents of the stomach enter the esophagus. Normally, this is impossible, since there is a narrowing between the esophagus and the stomach - the so-called lower esophageal sphincter, the muscle tone of which is regulated by the nervous and hormonal systems.

2 main causes of heartburn during pregnancy

In early pregnancy, during the first trimester of pregnancy, heartburn occurs due to a sharp increase in the level of the sex hormone progesterone. Progesterone relaxes all smooth muscles, incl. and muscles of the lower esophageal sphincter. This results in backflow of acidic contents into the esophagus. Usually this type of heartburn goes away by 13-14 weeks of pregnancy.

In the later stages of pregnancy, in the third trimester, due to the displacement of the internal organs, the stomach is squeezed and lifted, and thus the acidic contents more easily overcome the barrier between the stomach and esophagus and provoke a feeling of heartburn.

This must be understood!

Folk remedies for heartburn during pregnancy: milk, soda, seeds are unacceptable treatments. With their continued use, complications can occur.

Milk is not an adult dietary product. Most people develop physiological lactose intolerance after the age of 2 years, and excessive consumption of milk (more than 1-2 glasses per day) can cause diarrhea, bloating and abdominal pain.
Taking soda to suppress heartburn during pregnancy provokes an increase in the amount of gases and causes a "mirror response" of the stomach to a sharp alkalization of the contents - an increase in the acidity of the stomach and an increase in the alkalinity of the blood. This can provoke a feeling of heartburn, nausea, vomiting, diarrhea.

How to get rid of heartburn during pregnancy?

What can and cannot be done during pregnancy with heartburn? First of all, it is necessary to avoid taking foods that can increase the increase in stomach acidity - these are fatty, spicy, heavy foods. It is also not recommended to consume chocolate, coffee, freshly squeezed juices.

Recommended for heartburn during pregnancy to eat more vegetables and cereals. Eating should be fractional - about 5-6 times a day in order to evenly distribute the load on the stomach during the day, so that the gastric juice is always with food, and not in a free state.
Try to avoid stress, adhere to a normal mode of work, rest, sleep. After eating, walks are required (in no case do not lie down). The position of the body during the day should be such as not to increase intra-abdominal pressure - while sitting, do not cross your legs, the level of the knees should not be higher than the level of the hips. It is recommended to lie with a slightly raised upper body.

Preparations during pregnancy for heartburn.

The simplest and most reliable remedy is still alkaline water, bananas, pears, peeled peaches (but the doses should not be excessive). If there is no effect, they resort to well-established drugs that can be used to combat heartburn: Rennie or Gaviscon forte (WARNING!!! Self-medication can be harmful to your health).

MC "Academy of Your Health" recommends that you consult with a professional gastroenterologist or gynecologist to solve the problem associated with heartburn during pregnancy. The doctor will be able to competently assess the causes of your heartburn and offer an optimal and harmless treatment regimen, taking into account concomitant pregnancy.

Article "Pregnancy and heartburn"

Hormonal changes that the body undergoes during pregnancy is the root cause of heartburn. In early pregnancy, the ovaries, and then the placenta, produce the hormone progesterone, one of the main functions of which is to relax the smooth muscles of the body, including the muscles of the uterus. Similarly, progesterone acts on other smooth muscles in our body, for example, the muscles of the esophagus, stomach, and intestines. Progesterone also has a relaxing effect on the sphincters (circular muscles), the main task of which is to separate the various organs of the gastrointestinal system from each other. Relaxation of the esophageal-gastric sphincter leads to the fact that in pregnant women its lumen is open, and hydrochloric acid, which is produced by the stomach, can be thrown into the esophagus, which causes an unpleasant sensation of pain and burning - heartburn.

Another cause of heartburn in pregnant women is the weakening of motility - the wave-like movement of the gastrointestinal tract, slowing down the processes of digestion of food. Food passes through the digestive tract more slowly, lingering in the stomach. Heartburn in pregnant women is also provoked by the large size of the uterus, which increases intra-abdominal pressure and increases pressure on all the internal organs of the pregnant woman - the stomach and intestines as well. The stomach changes its location during pregnancy, pushed up and to the side by the uterus - all these factors also contribute to the violation of the motility of the esophagus, stomach and intestines and create conditions for the occurrence of heartburn.

Heartburn can start at any stage of pregnancy, but is most common in the second and third trimesters. As a rule, discomfort occurs after 24 weeks, when the uterus rises above the navel, and becomes especially severe after 30 weeks. Especially intense heartburn can be in a woman if she had an increased acidity of gastric juice before pregnancy.

To avoid heartburn during pregnancy, first of all, you need to review your menu and exclude fatty, fried, spicy, salty foods from it, you must give up coffee and carbonated drinks. Include cereals, dairy products, lean meats and mashed vegetables in the diet. It is advisable to eat often and in small portions every 1.5-2 hours. Spend more time eating, remember to chew food thoroughly so that it is digested properly. Drink water between meals, not with meals. After a meal, it is not recommended to sit or lie down, but take a walk for some time (about 30-40 minutes). Try to avoid sharp torso bending after eating. Do not eat at night, the last meal is desirable 2-3 hours before going to bed. Remember to put an extra pillow under your head, sometimes this helps to cope with heartburn. And if heartburn still appears, you need to try to reduce it.

At the first signs of heartburn, you can drink a small amount of alkaline mineral water without gas or take a few sips of low-fat milk. Drink should be in small sips. Kissels work well. They envelop the esophagus and thus reduce burning sensation. The safest in the treatment of heartburn in pregnant women are antacids containing sodium bicarbonate, calcium carbonate, preparations containing magnesium and other substances.
