What causes acid reflux during pregnancy – AC

Stomach has a valve, just at the entrance. The valve is a ring of muscle known as the lower esophageal sphincter (LES). As food passes through the valve, it closes. Acid produced by your stomach can move up into the esophagus, if the lower esophageal sphincter doesn't close completely. This can cause the hydrochloric acid along with the food to move towards the esophagus. A burning chest pain condition known as a heartburn, is the most common symptom of acid reflux. If the symptoms of acid reflux happen more than twice a week, then acid reflux disease occurs, also known as gastroesophageal reflux disease (GERD).

During the second and third trimesters of pregnancy, many pregnant women undergo a symptom of heartburn that is caused by acid reflux. A heartburn, also known as acid indigestion, is characterized as a burning sensation or irritation of the esophagus caused by the reflux of acid and food from the stomach.

The stomach acids can also come upwards by the pushing of the enlarged uterus by the crowding of abdomen. Gallstones can also cause acid reflux and heart burn during pregnancy.

  • Fried, spicy, or rich foods, should be avoided because they seem to cause relaxation of the lower esophageal sphincter. This increases the risk of acid reflux and heartburn.
  • Drink less water or other fluids while eating. Acid reflux and heartburn may be caused by drinking large amounts while eating
  • Avoid lying down directly after eating.
  • The head of your bed should be higher than the foot of your bed .
  • Place pillows under your shoulder to prevent the back reflux of acid from the stomach to the esophagus.
  • Over-the-counter medications such as Tums or Maalox, should be taken after a doctor’s consult. Only those OTC medications should be used that are safe to use during pregnancy. You may find that liquid heartburn relievers are more effective in treating heartburn, because they tend to cover the esophagus.

  • Constipation should be avoided.
  • See your doctor, if the acid reflux or heart burn persists. Your doctor may prescribe medications that are safe enough to take during pregnancy.
