Pregnant? How to relieve and prevent heartburn and acid reflux

Verified by: Midwife Maria Midstam 

Acid reflux and heartburn are very common during pregnancy - especially in the later weeks. It can be uncomfortable, but there are simple ways to prevent and relieve symptoms so that you can feel better in your everyday life.

Why do you get acid reflux when you are pregnant?

During pregnancy, the body produces more of the hormone progesterone, which relaxes the muscles of the gastrointestinal tract.
This means that stomach acid can rise more easily in the esophagus, causing heartburn or acid reflux.

As the uterus grows, it also presses against the stomach lining, further increasing the risk.

How acid reflux feels

Many pregnant women describe it as:

• A burning sensation in the chest or throat
• Sour in the mouth, especially after eating
• Nausea or discomfort when bending over
• Worsening of symptoms when lying down

Common causes during pregnancy

• progesterone relaxes the stomach muscles → stomach acid rises upwards.
• The uterus grows and presses against the stomach.
• Large meals or late dinners make it worse.
• Carbonated drinks and fatty foods can trigger heartburn.

How to relieve heartburn and acid reflux

There are many natural ways to relieve symptoms - try out what works best for you.

1. Eat small portions - often

Smaller, regular meals keep your stomach from getting too full. This reduces pressure and the risk of regurgitation.

2. avoid carbonated drinks

Carbon dioxide increases the pressure in your stomach. Drink still water or tea instead.

3. Raise your head when you sleep

Sleep with your upper body slightly elevated. This keeps the stomach acid in place.

4. Do not eat just before bedtime

Try to eat at least 2-3 hours before bedtime, so your stomach has time to digest the food.

5. get moving - but slowly

A short walk after eating helps digestion. Avoid going straight to bed.

6. Contact health care if necessary

If heartburn becomes severe, there are safe medicines for pregnant women that can help. Always consult your midwife or doctor.

When should you seek help?

Acid reflux is common - but you should always contact your healthcare provider if it occurs:

• You get severe pain in the chest or throat
• Disorders do not go away despite lifestyle changes
• You have difficulty swallowing or lose a lot of weight

The midwife can then refer you to a doctor who will assess whether you need medical treatment.
