The condition of hard stool indicates that the stool contains little water and stays inside the intestine for too long, in which too much water is absorbed. The first thing to consider is dietary habits, eating too much spicy and fried food, drinking less water and drinking alcohol can cause this symptom. It is recommended to first adjust the diet, encourage the patient to drink more water, eat more vegetables and fruits, and drink a glass of honey water in the morning to nourish the stomach. If the effect of dietary adjustment is not good, we should exclude the disease of intestine itself, such as polyps or chronic colitis inside the intestine, we need to do e-colonoscopy to clarify. If the polyp is clearly a polyp in the intestine, electrocoagulation and electrosurgery of the polyp should be performed under e-colonoscopy. If it is clear that the polyp is chronic colitis, you can consider the medication such as Pefixan or rectified intestine plus compound glutamine enteric granules to regulate. If the stool is very dry and not easy to pass, you can also use laxative medication, such as lactulose oral solution for laxative treatment.
