Reflux during pregnancy, what can I take?

Are you pregnant and does gastric reflux bother you very often? Here are some ways to help you relieve them, all compatible during pregnancy!

Why do some women have reflux when they are pregnant?

Hormonal changes during pregnancy cause relaxation in many tissues and muscles in the body, including the small muscle at the entrance to the stomach called the cardial sphincter. The latter then opens abnormally and can let the acidic contents of the stomach rise up into the esophagus, causing a burning sensation or digestive discomfort, which can even cause nausea in some women.

Reflux during pregnancy is also due to the slowdown in gastrointestinal transit, causing digestion to be slower and the stomach to empty less effectively than usual.

The diet

First, we will adapt the diet:

• by reducing food consumption:
  
  • acids (e.g. tomatoes, citrus fruits, soft drinks, etc.)
  • Fat
  • caffeine, chocolate, and theine
• by consuming protein at every meal
• by eating more often but in smaller portions (regular meals and repeated snacks)
• by avoiding drinking a large amount of liquid at meals or before bedtime

Reducing physical activity following food intake and reducing stress can also help limit reflux.

Sleep

To digest better and sleep better, eat while sitting. During the night, remember to raise the trunk, for example by adding a pillow.

Other methods to reduce reflux

Afterwards, if there is no improvement, we can try to try:

• Osteopathy
• Acupuncture
• Some antacids, available over-the-counter such as Maalox®, Tums® and Gaviscon®, can be taken occasionally, one hour after meals (always check with your pharmacist before starting to take a new medication).

If you have to take several antacids a day and/or if it only partially relieves you, it is best to consult your doctor for a prescription treatment that is better suited to your situation.
