Suffering from heartburn during pregnancy? Don’t worry, 82% of pregnant women do.

Causes & Symptoms

What causes heartburn during pregnancy? Well, there are usually two main reasons you’re suffering:

  1. Hormones released during pregnancy cause a relaxation of the muscle, which may result in the acidic stomach content to enter the oesophagus more easily.
  2. As the baby grows it causes intra-abdominal pressure on the muscle, making the acid in stomach escape easily to the oesophagus.
