Pregnancy Heartburn Relief: How to Manage Heartburn and Acid Reflux in Pregnancy
Awaiting the arrival of your little one is an exciting time as you count down the months, weeks and days – but it can also be a time of little niggles and gripes, such as heartburn in pregnancy.
Be reassured though that heartburn – a burning feeling in the chest caused by stomach acid travelling towards the throat (acid reflux) – is common during pregnancy and there are ways to help ease the symptoms.
What causes heartburn during pregnancy?
Heartburn during pregnancy is very common and thought to affect up to 80% of women at some point during pregnancy. It happens when stomach acid travels back up into the oesophagus (food pipe), causing the familiar burning sensation in the chest known as acid reflux.
One of the reasons for pregnancy heartburn is the hormonal changes that support your growing baby.
During pregnancy, your body produces higher levels of the hormone progesterone. While progesterone plays an essential role in maintaining a healthy pregnancy, it can also relax the muscular valve that normally keeps stomach contents where they belong. When this valve relaxes, stomach acid can more easily escape into the oesophagus, leading to heartburn symptoms.
Your growing baby pressing against the stomach can make the problem worse.
As your pregnancy progresses, your growing baby and expanding uterus place increasing pressure on your stomach. This pressure can push stomach contents upwards, making heartburn during pregnancy more likely. For this reason, many women notice their symptoms become more common during the third trimester, when the baby is growing rapidly and taking up more space in the abdomen.
Thankfully, for most expectant mums, pregnancy heartburn is temporary and often improves or disappears soon after the baby is born, when hormone levels return to normal and the pressure on the stomach is relieved.1 Until then, however, it can be unpleasant and uncomfortable.

What are the symptoms of heartburn during pregnancy?
Symptoms of heartburn include:
- A burning sensation or pain in the chest
- An unpleasant sour taste in the mouth caused by stomach acid
- Burping
- Feeling full, heavy or bloated
- Feeling or being sick
- Bringing up food
It usually occurs soon after eating or drinking – although there can be a delay in the symptoms appearing – and it can happen during any stage of pregnancy, however it tends to be more common from 28 weeks onwards as the baby starts to grow bigger.
Although it’s natural to be concerned, heartburn doesn’t usually harm you or the baby but if you are worried it’s best to speak to your midwife or GP.
Pregnancy heartburn relief
If you’re experiencing heartburn when pregnant, there are some simple lifestyle changes that may help to reduce your symptoms.
Advice to help ease the condition includes:
- Instead of eating three large meals a day, try eating smaller meals more frequently.
- Some foods and drinks can make heartburn worse. Although triggers vary from person to person, many people find it helps to cut down on spicy foods, fatty or rich meals, chocolate, citrus fruits, fizzy drinks and drinks containing caffeine, such as tea, coffee and cola. Keeping a food diary may help you identify any foods that seem to trigger your symptoms.
- Sitting up straight during and just after meals allows gravity to help keep stomach contents where they belong. Avoid lying down immediately after eating and, where possible, wait at least three hours after eating before lying down for the night.
- If heartburn when pregnant is disturbing your sleep, try propping up your head and shoulders. Sleeping in a slightly elevated position may help reduce acid reflux raining upwards during the night.
- Wearing loose-fitting clothing around your waist may reduce pressure on your stomach.
- If you smoke, stopping smoking is one of the best things you can do for both your own health and your baby’s health, and it may also help reduce reflux symptoms. Your midwife or GP can provide advice and support to help you quit.

Heartburn during pregnancy is usually caused by a combination of hormonal changes and physical pressure from your growing baby. Higher levels of progesterone can relax the valve between the stomach and oesophagus, making it easier for stomach acid to travel upwards. As your baby grows, the uterus also presses against the stomach, which can make symptoms worse.
Is heartburn during pregnancy normal?
Yes. Heartburn is a common symptom during pregnancy and is thought to affect up to 80% of pregnant women. Although it can be uncomfortable, it does not usually harm you or your baby.
