In the early stages of pregnancy, the treatment for acidity and heartburn are: I. Eat reasonably. Do not eat too much, so as not to raise the pressure in the stomach. Eat less and more often, slow down the speed of eating, chew and swallow slowly. In particular, do not oversaturate dinner too late, preferably eat within 2-3 hours before bedtime. This gives enough time to digest the food. Avoid eating drinks and food that cause gastrointestinal discomfort, usually do not drink carbonated beverages, alcohol, stimulating food, etc. Second, sleep position is important. Sleep at night with a few extra pillows to elevate the upper body. The foot of the bed at the head is elevated 15-20cm, so that the upper body is elevated 10°-15°, which can effectively reduce esophageal reflux. Third, loose clothing. To reduce esophageal reflux, pregnant women’s clothes should be loose. If they are strangled by too tight clothes on the waist and abdomen, it will produce esophageal reflux. In addition, bowel movements should be smooth and active to prevent and control infections so as not to increase intra-abdominal pressure, which can reduce the symptoms of stomach acid and heartburn.
