Heartburn in pregnant women is one of the most common complaints and, according to clinical data, may affect 30 to 80% of expectant mothers. This symptom often worsens after eating, when lying down, when bending forward, after overeating, or after consuming foods that may irritate the stomach lining.
Heartburn can cause a feeling of constant discomfort, worsen appetite, and interfere with normal sleep, especially if it occurs every day. At the same time, it is important to understand that during pregnancy not all usual ways of relieving the condition are safe. Home methods should be used carefully, and medications should be used only after consulting a doctor.
In this article, we will discuss why heartburn occurs, when it appears most often, and what can help an expectant mother. We will also consider in which cases it is necessary to seek medical help.
Heartburn during pregnancy: what it is and why it occurs
Heartburn may manifest as a burning sensation behind the breastbone, a sour or bitter taste in the mouth. It occurs because stomach contents flow back into the esophagus. Normally, there is a lower esophageal sphincter between the esophagus and the stomach — a muscular ring that works like a valve. It opens when food passes into the stomach and closes so that stomach contents do not flow back.
During pregnancy, this mechanism may work less tightly: acidic contents can more easily enter the esophagus and irritate its lining. The symptom may be mild or, on the contrary, bother a woman every day, accompanied by sour belching, nausea, a feeling of fullness in the stomach, throat irritation, or coughing after eating. The materials of the NHS state that heartburn and digestive problems during pregnancy may be associated with hormonal changes and pressure from the enlarged uterus on the stomach.
Why pregnant women have heartburn
The main cause of heartburn during pregnancy is a combination of hormonal and mechanical factors. In the early stages, progesterone levels increase. This hormone is necessary for the normal course of pregnancy, but at the same time it relaxes smooth muscles, including the lower esophageal sphincter. Because of this, the “valve” between the stomach and the esophagus may close less tightly.
Progesterone can also slow down the digestive system. Food stays in the stomach longer, the feeling of fullness lasts longer, and the risk of stomach contents flowing back increases. In the second half of pregnancy, a mechanical factor is added: the enlarged uterus changes the pressure in the abdominal cavity, so heartburn may become more frequent.
Additional factors can worsen reflux:
- excessively large food portions;
- dinner shortly before bedtime;
- the habit of lying down immediately after eating;
- fatty, fried, spicy, or acidic foods;
- carbonated drinks, strong coffee, chocolate;
- tight clothing that compresses the abdomen;
- stress, eating in a hurry, irregular meals.
Doctors at Oxford Medical note: if a woman previously had GERD, that is, gastroesophageal reflux disease, symptoms may worsen during pregnancy. In this case, it is not worth explaining all discomfort only by natural changes in the body of the expectant mother. It is better to discuss complaints with a doctor in order to choose a safe strategy for relieving the condition.
Can heartburn be a sign of pregnancy
Heartburn may appear in the early stages of pregnancy, but it is not considered a reliable or specific sign. It may be associated with hormonal changes, increased sensitivity of the digestive system, nausea, changes in eating habits, or a reaction to certain foods. However, reflux alone does not confirm pregnancy.
In the early stages, more typical signs may include a missed period, breast tenderness, nausea, drowsiness, more frequent urination, changes in appetite, or reactions to smells. However, even these manifestations do not provide an exact answer without a pregnancy test, a blood test for hCG, or an ultrasound examination.
When heartburn starts in pregnant women

Heartburn may appear at any stage of pregnancy: in some women — already in the first weeks, in others — closer to the second or third trimester. According to the NHS, symptoms can occur at any time during pregnancy, but they are more common after the 12th week.
Heartburn in early pregnancy
In the early stages, reflux more often occurs due to changes in the motility of the digestive system. During this period, the stomach may empty more slowly, so after eating, heaviness, belching, or a sour taste in the mouth may last longer.
The symptom may be worsened by morning sickness, nausea, sensitivity to smells, and irregular eating. For example, a woman may skip food because of nausea and then eat a larger portion — this creates an additional load on the stomach.
Heartburn during pregnancy: first trimester
In the first trimester, heartburn is often combined with nausea, changes in appetite, and intolerance to certain foods. Therefore, the main task at this stage is to understand whether the symptom is related only to pregnancy or whether it overlaps with already existing digestive problems.
Doctors at Oxford Medical note: during this period, it is not recommended to take heartburn medications on your own. Even familiar remedies may have restrictions during pregnancy, especially in the early stages. During scheduled checkups as part of pregnancy care, it is worth telling the doctor about frequent heartburn, nausea, vomiting, or a sharp narrowing of the diet.
Heartburn during pregnancy: 2nd trimester
In the second trimester, morning sickness decreases in many women, but reflux may persist or appear for the first time. At this stage, the uterus gradually increases, so the symptom more often occurs after a large meal, bending forward, or resting in a horizontal position.
In the second trimester, it is important to track not all possible “forbidden” foods, but individual triggers specifically. Reactions may differ from woman to woman: for some, discomfort is provoked by acidic fruits, for others — coffee, chocolate, fresh baked goods, or fatty dishes. It is not worth sharply restricting the diet without the need to do so.
Doctors at Oxford Medical note: heartburn may worsen if there is constipation, because an overfilled intestine increases intra-abdominal pressure. In this case, it is worth discussing fluid intake, the amount of fiber in the diet, and permissible physical activity with a doctor. Laxatives should not be taken independently during pregnancy.
Heartburn during pregnancy: third trimester
In the third trimester, reflux often becomes most noticeable because the enlarged uterus presses more strongly on the stomach. The symptom may appear even after a small portion, bother a woman more often in the evening, or interfere with sleep.
Discomfort may also be worsened by flatulence, since excess gas creates additional pressure in the abdomen. If bloating, heartburn, and heaviness after eating repeat often, it is worth reviewing portion size, eating pace, food combinations, and drinking routine together with a doctor.
In the third trimester, any pain or sudden deterioration in well-being should not be attributed to “ordinary heartburn.” If the symptom is accompanied by repeated vomiting, difficulty swallowing, abdominal pain, loss of appetite, or sleep disturbance, a doctor's consultation is needed.
What to do for heartburn in pregnant women

For heartburn during pregnancy, the approach depends on the frequency and severity of symptoms. If discomfort occurs occasionally, correction of nutrition and daily routine is usually the first step. If the symptom repeats often, interferes with sleep or eating, it is necessary to see a doctor. The NHS recommendations state that safe medications may be used during pregnancy, but they should be selected taking into account the woman's condition and other medications she is taking.
How to get rid of heartburn during pregnancy at home
To reduce heartburn at home, you can:
- eat smaller portions, but more often;
- avoid long breaks between meals;
- avoid having dinner right before bedtime;
- remain upright after eating;
- avoid bending forward immediately after eating;
- choose clothing that does not compress the abdomen;
- raise the upper part of the body during sleep if reflux bothers you at night.
These tips do not replace treatment, but they may reduce the frequency of episodes. If home methods do not help, symptoms should be discussed with a doctor.
What helps pregnant women with heartburn
Pregnant women may be helped by three groups of measures: changing eating habits, eliminating individual triggers, and medications approved by a doctor.
The following may be useful:
- correction of the eating routine;
- temporary restriction of foods that definitely worsen the symptom;
- a short walk after eating;
- antacids or alginates, if recommended by a doctor.
Doctors at Oxford Medical recommend not taking heartburn medications independently. According to the NHS, antacids may affect the absorption of iron and folic acid, so it is important to follow recommendations regarding the timing of intake.
What pregnant women can use for heartburn
If a patient is looking for what pregnant women can use for heartburn, the safest option is to start with simple actions that do not harm the course of pregnancy. It is possible to choose warm, not too fatty food, drink still water in small sips, avoid overeating, and take heartburn remedies only after approval from a doctor.
It is not advisable to take several remedies at the same time or exceed the dosage. If reflux repeats every day, constant self-help is not needed — a doctor's consultation is needed instead.
What water is recommended for heartburn in pregnant women
Water for heartburn in pregnant women should be still, at room temperature, or slightly warm. It is better to drink it in small sips between meals. A large amount of fluid at one time may increase the feeling of stomach fullness.
It is better to choose ordinary still drinking water. Carbonated water may increase belching, bloating, and discomfort, so it is better to limit it.
Can pregnant women drink baking soda for heartburn
Drinking baking soda is not recommended for pregnant women. It may provide short-term relief, but often after that reflux returns, while bloating and belching increase.
Baking soda contains sodium, so it is undesirable to use it regularly, especially with a tendency to swelling, high blood pressure, or kidney problems. If heartburn is severe, repeats several times a week, or does not go away after changing nutrition, a gastroenterologist consultation or an obstetrician-gynecologist consultation is needed. The doctor will help choose a safe way to relieve the condition and determine whether the symptoms are associated with other diseases of the digestive system.
When to see a doctor

It is necessary to see a doctor if reflux during pregnancy occurs often, does not decrease after dietary changes, or begins to affect sleep, appetite, and overall well-being.
Do not postpone seeing a doctor if there is:
- heartburn every day or several times a week;
- pain in the upper abdomen;
- difficulty swallowing;
- a feeling that food “gets stuck” in the throat or behind the breastbone;
- repeated vomiting;
- inability to eat or drink normally;
- decreased appetite or noticeable weight loss;
- persistent cough, hoarseness, or throat irritation;
- severe weakness, dizziness, deterioration in well-being;
- appearance of dark stool or blood impurities in vomit.
Sometimes such symptoms may be associated not only with pregnancy, but also with diseases of the digestive system, in particular GERD, gastritis, Helicobacter pylori infection, or peptic ulcer disease. In such cases, the doctor will assess the complaints, take into account the stage of pregnancy, and choose a safe strategy for relieving the condition.
Doctors at Oxford Medical recommend not tolerating heartburn and not taking remedies “blindly” if the symptom repeats regularly. A safe strategy depends on the cause of the complaints: sometimes dietary correction is enough, and sometimes additional examinations or individually selected treatment are needed.
