Clinical manifestations of lactose intolerance include abdominal distension, hyperactive bowel sounds, abdominal pain, diarrhea, nausea and vomiting.
1. Bloating: Lactose cannot be digested and broken down in the body, resulting in a large accumulation of lactose, which increases the pressure in the stomach and causes bloating.
2. Hyperactive bowel sounds: Lactose cannot be digested and broken down, which stimulates the intestinal peristalsis to speed up, resulting in hyperactive bowel sounds.
3. Abdominal pain: lactose that cannot be digested and absorbed by the body stimulates abnormal peristalsis of the intestinal wall, resulting in colic.
4. Diarrhea: Lactose intolerance is caused by the lack of lactase enzyme, the concentration of lactose in the intestinal tract continues to increase, affecting the osmotic pressure of the intestinal tract, stimulating the intestinal tract, causing diarrhea. Its feces are mostly yellow loose stools, in the form of eggdrop soup.
5. Nausea, vomiting: lactose can not be digested and absorbed, stimulating the abnormal peristalsis of the stomach and intestines, triggering nausea and vomiting clinical manifestations.
Lactose intolerant patients are advised to seek prompt medical attention if the above clinical manifestations occur.
