Pregnant women can take sodium bicarbonate tablets in moderation because the severity of pregnancy reaction varies with each person’s constitution after pregnancy. Some people may experience acid reflux, nausea, loss of appetite and other symptoms, and can take sodium bicarbonate tablets to help neutralize stomach acid and reduce the symptoms of pregnancy reaction. If you are suffering from gastritis or gastric ulcer, which leads to increased secretion of stomach acid, you can also use the medicine under the guidance of your doctor, but do not take it in excess. Be careful to maintain a regular diet and eat more food that nourishes the stomach.
