The symptom performance of gastric distension in early pregnancy is a normal physiological phenomenon, because the elevated levels of various hormones such as progesterone, estrogen and adrenaline in the body and the accelerated metabolic rate in the body will increase the functional burden of the stomach, intestines and other digestive tract tissues and lead to a decrease in their operational efficiency, so it leads to the physiological performance of gastric distension and pain in early pregnancy. However, it is not excluded that patients have digestive system diseases, such as superficial gastritis, Helicobacter pylori infection, gastric neurofibroma, etc. This is because organic lesions in the gastrointestinal tract can seriously affect the normal functioning of the patient and cause pain in the stomach, nausea, vomiting, bloody stools, pus and other symptoms. Pregnant women with persistent or worsening symptoms need to go to the hospital and be examined in time to avoid delays.
