Indigestion and heartburn

What causes indigestion?
From the start of pregnancy, hormonal changes relax the valve at the top of your stomach, which means stomach acid can pass back into the food pipe (oesophagus). This can cause discomfort in the chest or a burning feeling also known as heartburn. Indigestion is most common after eating but can happen at any time of day or night.

In later pregnancy, your growing uterus starts to press on your stomach. This puts pressure on your stomach capacity, pushing it upwards, making you feel uncomfortable after eating and can force even more stomach acid back into your oesophagus.

The combination of hormones and your growing baby means indigestion can strike at any stage of pregnancy, although it is often worse in the last trimester. You may find you suffer most at night, because when you are lying down it is easier for acid to travel back up into the food pipe.

Easing the symptoms of heartburn and indigestion

• Eat little and often, rather than having larger meals further apart.
• Sit up straight when you are eating to take the pressure off your stomach.
• Avoid eating things that trigger an attack of heartburn, including fried and spicy foods.
• Drinking a glass of cold milk can help ease the burning sensation of heartburn.
• Avoid eating or drinking in the two hours before going to bed.
• Sleep in a semi-upright position, propped up on pillows for example.
  
  

When to get help
Heartburn and indigestion are not dangerous to you or your baby, but can disturb your sleep and make you feel very uncomfortable. If you are struggling to cope, talk to your midwife or GP for advice. They may prescribe an antacid medication to relieve the symptoms. Your pharmacist can also give you advice about over-the-counter heartburn and indigestion remedies that are safe to take in pregnancy.
