Dr. Chrysoula I. Liakou MD, PhD
- Treated online: Yes, usually. Video assessment, with a prescription when appropriate.
- Antacids and alginates after meals and at bedtime are the usual first steps for indigestion in pregnancy; new severe pain under the ribs after 20 weeks, especially with headache or vision changes, is a pre-eclampsia warning, not heartburn.
- Omeprazole is the most-studied acid-reducing tablet in pregnancy and is prescribed when antacids and alginates are not enough.
- Antacids block iron absorption, so take them about 2 hours apart from iron tablets.
- Call 112 for a seizure, or if someone pregnant becomes very unwell very quickly.
After 20 weeks of pregnancy, do not assume upper-belly pain is indigestion. Pain high in the abdomen or under the ribs, especially on the right, with a severe headache, visual disturbance (flashing lights, blurring), sudden swelling of the face, hands or feet, or vomiting, can be pre-eclampsia. Contact your midwife or maternity unit immediately, at any hour, or call 112 if you cannot reach them or feel very unwell. Also get same-day in-person care for difficulty swallowing, vomiting blood or material like coffee grounds, or black tar-like stools.
What can I take for indigestion in pregnancy?
Start with mechanics: smaller meals eaten slowly, nothing large within 2–3 hours of bed, and the head of the bed raised. Antacids and alginate preparations, the kind that form a protective raft on top of the stomach contents, are considered suitable in pregnancy and are the usual first medicines, taken after meals and at bedtime. When symptoms keep breaking through, doctors can prescribe omeprazole, an acid-reducing tablet widely used in pregnancy.[1][3] Availability and prescribing rules vary by country; a doctor confirms what fits your stage.
That ladder exists because pregnancy heartburn is mechanical and hormonal at once, and because each rung has good safety data behind it. Most women get control at the alginate step. The point of a consultation is to climb exactly as far as you need and no further, and to make sure nothing about your story argues for a different diagnosis altogether.
How an online consultation helps with indigestion in pregnancy
- The safety question answered properly: which antacids, alginates and acid reducers are considered suitable at your stage, with honest notes on each, instead of a shelf of products all warning you to ask a doctor.
- The pre-eclampsia line drawn clearly: the doctor actively checks that your “heartburn” is heartburn, because new upper-abdominal pain in later pregnancy has one dangerous mimic that must never be missed.
- Iron and antacids untangled: antacids block iron absorption when taken together. The doctor times them properly so your anaemia protection keeps working.
- A plan that scales with the trimester: heartburn typically worsens as the uterus grows. You leave with a stepped plan for the months ahead, not just a fix for tonight.
What the doctor checks in an online pregnancy indigestion consultation
The consultation is structured to confirm the pattern and rule out the mimics. The doctor will typically work through:
- The symptom itself: burning behind the breastbone, acid or food coming back up, bloating and burping after meals, and the timing, after eating, on lying down, or on bending.
- Your stage of pregnancy: heartburn can start in the first trimester but typically builds through the third as pressure rises; stage also frames what any new pain might mean.
- Warning symptoms, checked directly: pain high under the ribs (especially the right), severe headache, visual changes or sudden swelling after 20 weeks; difficulty swallowing; vomiting blood; black stools; and weight loss.[2]
- What you have already tried: which antacid or alginate, at what dose and timing, because “it didn’t work” often means “it was taken before meals instead of after”.
- Your other medicines and supplements: iron (which antacids block and reflux worsens), and anything else that irritates the stomach.
- Eating and sleeping patterns: meal sizes, late eating, trigger foods, caffeine, and how you prop yourself at night, the simple levers that genuinely move symptoms.
- Nausea and vomiting: where sickness dominates over burning, the assessment shifts, because that is a different pregnancy problem with its own care.
Why is heartburn so common in pregnancy?
Progesterone relaxes the valve between the oesophagus and the stomach, so acid escapes upwards more easily; digestion also slows, keeping the stomach fuller for longer; and from mid-pregnancy the growing uterus pushes the stomach upwards from below. It is a mechanical problem that intensifies as the bump grows, peaks in the third trimester, and resolves for the great majority of women soon after birth.[1] Heartburn is miserable, but it does not harm the baby, and the folklore that it predicts a hairy one is exactly that: folklore, plus one small study that made headlines.
Is omeprazole safe in pregnancy?
Omeprazole is the most-studied acid-reducing tablet in pregnancy, and large studies have not shown an increased risk of harm to the baby; it is prescribed when antacids and alginates are not enough.[3] That is honest reassurance, not a licence for self-medicating: the decision belongs in a conversation with a doctor, who confirms the diagnosis, the dose and the duration for your stage of pregnancy.
Two related honesty notes. Ranitidine, the acid reducer many people remember from earlier pregnancies, was withdrawn across the EU in 2020 over an impurity concern, so older advice mentioning it is out of date; other options have replaced it.[4] And acid reducers work best as a planned course with a review, not an open-ended habit: after birth, most women can stop them entirely, and the doctor builds that exit into the plan.
Which step of the pregnancy reflux ladder are you on?
This is the framework our doctors use, aligned with cited guidance:
Swipe sideways to compare →
| Presentation | Likely first step | Suitable for online care? | When referral or in-person care is needed |
|---|---|---|---|
| Burning after meals or on lying down, acid taste, burping | Meal and position changes, plus an antacid or alginate after meals and at bedtime[1] | Yes, often without a prescription | Not settling within 1–2 weeks of proper use |
| Reflux breaking through despite regular alginates | Omeprazole after video review, with dose and duration agreed[1][3] | Usually yes | No response to treatment, or any alarm feature appearing |
| Reflux plus iron supplements | Timing plan: iron and antacids separated by about 2 hours | Usually yes | If anaemia needs re-testing, bloods are arranged locally |
| New pain high under the ribs after 20 weeks, especially right-sided, or with headache, vision changes or swelling | Urgent maternity assessment for pre-eclampsia, including blood pressure and urine checks[2] | No | Immediately: midwife or maternity unit, or 112 |
| Difficulty swallowing, vomiting blood, black stools, or weight loss | In-person assessment and tests | No | Same day |
Availability of individual medicines and who may prescribe them vary by country; your doctor confirms what applies where you are.

What you can do yourself
Eat smaller amounts more often, slowly, and finish eating 2–3 hours before lying down. Notice your own triggers rather than banning everything: fatty and spicy meals, chocolate, citrus, tomatoes, fizzy drinks and caffeine are the usual suspects, but they vary woman to woman. Raise the head of the bed 10–15 cm with blocks or a wedge (extra pillows alone tend to fold you at the waist and make it worse), and lie on your left side, which positions the stomach below the oesophagus. Loose clothing around the waist helps more than it sounds like it should. Antacid and alginate preparations from the pharmacy are considered suitable in pregnancy when used as directed; take them after meals and at bedtime, and separate them from iron tablets by about 2 hours so the iron still absorbs.[1][5]
Prescription treatment
A prescription is never issued without a consultation. After assessment, the doctor typically prescribes omeprazole where alginates are not enough, at the lowest effective dose with a review date; other acid reducers exist and choices vary by country.[1][3] Where nausea and vomiting dominate, or pain does not behave like reflux, the doctor says so and redirects the work-up rather than stacking acid medicine on the wrong problem. Antibiotic-based treatment for Helicobacter pylori, sometimes relevant outside pregnancy, is generally deferred until after birth, and antibiotics are only ever prescribed when there are genuine signs they are needed.
When is it not just indigestion?
The one mimic that must never be missed sits in later pregnancy: pre-eclampsia can announce itself as pain high in the abdomen, classically under the right ribs, often with a severe headache, visual disturbance or sudden swelling, from 20 weeks onwards. It is caused by rising blood pressure affecting the liver, not by acid, and no antacid will touch it. That combination is checked urgently, in person, with a blood pressure cuff and a urine test, the same day it appears.[2] If heartburn medicine that previously worked suddenly stops explaining your pain, treat that change with respect.
Other patterns that step outside the reflux ladder: pain that bores through to the back after fatty food (gallstones are commoner in pregnancy), burning that comes with vomiting blood or black stools (a bleeding ulcer, rare but urgent), and difficulty swallowing, which always earns examination. Digestive complaints also travel in packs during pregnancy: many women juggling reflux are also managing constipation in pregnancy, and the same consultation can sort both. Outside pregnancy, the work-up is different again; our general indigestion treatment online guide covers that path.
When we treat indigestion in pregnancy online, and when we refer you
We treat online: Mobi Doctor, an online healthcare service with licensed doctors, manages typical pregnancy heartburn and indigestion at every stage: lifestyle plans, antacid and alginate guidance, omeprazole when the ladder reaches it, iron-timing conflicts, and reviews when symptoms change as the bump grows.
We refer or redirect you: any suspicion of pre-eclampsia (upper-abdominal pain after 20 weeks with headache, visual changes, swelling or simply feeling wrong), immediately to your midwife, maternity unit or emergency care, with 112 when you cannot reach them; alarm features, difficulty swallowing, vomiting blood, black stools, unexplained weight loss, for in-person tests; suspected gallstone pain; and severe vomiting with dehydration, which needs in-person treatment. The pregnancy conditions hub collects everything we assess during pregnancy.
When to get in-person care
Contact your midwife or maternity unit immediately, day or night, for new pain high in the abdomen or under the ribs after 20 weeks of pregnancy, especially with a severe headache, flashing lights or blurred vision, sudden swelling of the face, hands or feet, or vomiting: this can be pre-eclampsia, and it is checked the same day, not watched. Call 112 if you cannot reach them, have a seizure, or feel very unwell very fast. Also seek emergency care for vomiting blood or material like coffee grounds, black tar-like stools, or chest pain with breathlessness or spreading to your arm or jaw.

Frequently asked questions about indigestion and heartburn in pregnancy
Can an online doctor prescribe omeprazole for heartburn in pregnancy?
Yes, where it is the right step. After a video assessment, the doctor can prescribe omeprazole when antacids and alginates are not controlling symptoms; it is the most-studied acid reducer in pregnancy. A prescription is never issued without a consultation, it can go to a pharmacy near you in most EU countries, and prescribing rules vary by country.
How much does a pregnancy indigestion consultation cost?
The exact price of a video consultation is shown before payment, and there is no subscription. Appointments run daily from 7am to 11pm, often within about 15 minutes.
Which antacids are safe during pregnancy?
Calcium- and magnesium-based antacids and alginate raft preparations are considered suitable in pregnancy when used as directed, taken after meals and at bedtime. Take them about 2 hours apart from iron tablets, which they stop absorbing. If you find yourself using them constantly, that is the signal for a review rather than more of the same.
Are alginate heartburn remedies safe while pregnant?
Yes. Alginates form a floating raft on top of the stomach contents that physically blocks acid from rising, they act locally rather than entering the bloodstream in meaningful amounts, and they are a standard first choice for pregnancy heartburn. They work best taken after food and before bed, once symptoms are already likely.
Why is my heartburn worse at night, and what helps?
Lying flat removes gravity, so acid reaches the oesophagus easily, and a slow pregnant stomach is often still full at bedtime. Finish eating 2–3 hours before lying down, raise the head of the bed 10–15 cm, sleep on your left side, and take an alginate last thing at night. That combination fixes most night-time burning.
Can heartburn in pregnancy be a sign of something serious?
Usually not, but there is one exception worth memorising: after 20 weeks, pain high in the belly or under the right ribs, particularly with severe headache, vision changes or sudden swelling, can be pre-eclampsia rather than heartburn. That needs urgent same-day assessment by your midwife or maternity unit, not a stronger antacid.
Will my heartburn stop after the birth?
For the great majority of women, yes, within days to weeks of delivery, as hormones settle and the pressure comes off the stomach. Any acid-reducing tablets can then usually be stopped, with a plan agreed at your review. Symptoms that persist months after birth deserve a fresh assessment rather than indefinite antacids.
Which heartburn medicines are used in pregnancy when antacids stop working?
There is a well-trodden ladder. Simple antacids and alginates come first and fix most weeks. When burning still wakes you or returns daily, acid-reducing tablets are widely used in pregnancy: omeprazole is the best-studied of its class, and ranitidine-era alternatives have been replaced by similar modern options. The point of the consultation is to choose the step that matches your pattern, check nothing about your symptoms suggests a different problem, and stop the common cycle of under-dosing antacids for months of misery.
