Why is heartburn during pregnancy a common problem?
Heartburn and acid reflux are common in pregnancy. In fact, it’s so common that patients and obstetricians both view it as a normal occurrence during a healthy pregnancy. 1,2,3
Estimates vary, but somewhere between 17% and 80% of women experience heartburn during pregnancy. 1,2,3
These symptoms may be frequent, severe and distressing, but serious complications for your baby are rare. 2
Symptoms can occur in all trimesters of pregnancy. 2 Most patients begin to note their symptoms late in the first trimester or second trimester of pregnancy with heartburn becoming more frequent and severe in the latter months of gestation. 1,3
If you’re suffering with symptoms of heartburn (such as a burning sensation behind your rib cage at the top of your chest 2,4,5) how can you tell what’s causing your discomfort?
What causes of heartburn during pregnancy?
The two most common causes of heartburn during pregnancy are:
- Progesterone Surge – The surge in the hormone progesterone during pregnancy causes your muscles to relax. This includes the sphincter (ring of muscle) at the entrance to your stomach. When this relaxes, stomach acids can travel back up into your oesophagus (food pipe) to cause heartburn. 2,3
- Pressure from Baby – as your baby grows and your uterus enlarges to make space for them, this puts pressure on your digestive tract. 2

What medicines are suitable to take for you and your baby?
During pregnancy, you’ll naturally be wary about taking medicines. However, you don’t need to put up with the symptoms of heartburn or indigestion as there are suitable remedies available.
Gavisсon Advance is a non-systemic medication (which means it doesn’t go in the bloodstream) so it’s suitable for use during pregnancy and while breastfeeding. 1,7,8

In safety and effectiveness studies, pregnant women who rated Gavison as effective usually got symptom relief within 10 minutes of taking the medication. Frequency and severity of heartburn decreased both in the day and at night after treatment. 1,3
Medicines can affect the unborn baby. Always talk to your doctor or pharmacist before taking any medicine in pregnancy.
How does Gaviscon Advance work?
How Gaviscon Advance works:
- As you swallow Gaviscon liquid, it soothes the throat and oesophagus. 9
- When it gets to your stomach, it only takes a few seconds for the sodium alginate in Gaviscon to react with the acid in your stomach to create a protective barrier or raft that floats on top of stomach contents. This raft keeps stomach acid from rising up and causing heartburn and indigestion symptoms. 7,8
When should you take Gaviscon?
- Take Gaviscon Advance when you experience heartburn symptoms, or when they start to occur, such as after meals or just before bedtime. Consult the package insert for the dosage that’s best for you. 7,8
