What causes stomach discomfort in late pregnancy

With the growth and development of the fetus in the third trimester, the increase of uterine height and abdominal circumference, the elevation of diaphragm, the decrease of gastric receptivity, and the weakening of gastrointestinal motility. The increase of progesterone makes the gastric sphincter relax, and the acidic contents in the stomach flow back to the lower part of the esophagus, which is easy to produce stomach burning sensation. And the emptying of the stomach is often prolonged, so the stomach will always feel uncomfortable. But this situation can generally be relieved by light diet, small meals, and gastrointestinal motility. If not, timely treatment, choose some drugs to inhibit stomach acid, conducive to defecation methods, should be able to alleviate.
