Causes of heartburn during pregnancy

The two main causes of heartburn in pregnancy are:
  1. Hormonal changes during pregnancy

    The surge in the hormone progesterone causes muscles to relax. This includes the sphincter (ring of muscle) at the entrance to the stomach. When this relaxes, stomach acids are able to travel back up into the esophagus (food pipe) causing painful heartburn.
  2. The growing fetus physically exerts pressure on your digestive tract

    During the latter stages of pregnancy, symptoms can be caused by the growing womb (uterus). As the baby grows, it physically exerts pressure on your digestive tract.
Other causes & triggers of heartburn during pregnancy
Heartburn tends to have similar triggers such as lifestyle and diet choices. A healthy diet is an important part of a healthy lifestyle for anyone, but it is vital when pregnant. Being careful of what you eat during pregnancy will help your baby develop and grow, as well as reduce the risks of heartburn.
The key heartburn triggers to watch out for when pregnant include:1
  • Black pepper, garlic, raw onions and other spicy foods
  • Chocolate
  • Citrus fruits and products, such as oranges and orange juice
  • Coffee and caffeinated drinks, including softdrinks
  • Peppermint
  • Large meals
  • Fatty foods
  • Late night snacks

How to treat heartburn during pregnancy

Now the various heartburn triggers have been identified, making changes to your lifestyle and diet is one of the most effective ways to help reduce the risks of suffering from heartburn during pregnancy. Here are some tips to prevent indigestion and heartburn:
  • Keep your weight in track
  • There is no need to “eat for two” when pregnant - eat smaller meals more frequently during the day
  • Take your time eating - chew every mouthful slowly, this will help break down the food into smaller pieces which aids digestion
  • Avoid spicy, acidic and fatty food because these can aggravate the stomach lining and cause more stomach acid to be produced
  • Sit up straight when you eat – avoid lying on the sofa or bed if you can help it
  • Loosen clothes or belts that are too tight, opt for loose-fitting maternity wear
  • Don't eat late or when on the run – take time for your meals
  • Try not to take big gulps of liquid, sip instead
