The main manifestation of diabetic enteropathy is diabetic diarrhea. These patients generally have a long and severe course of the disease, which is mostly complicated by autonomic and peripheral neuropathy. The incidence has been reported to be 16.7%. The pathogenesis of diabetic diarrhea is still unclear. Some people believe that diabetic diarrhea is common in patients with poor glycemic control combined with neuropathy; others believe that diarrhea may be caused by delayed passage of the small intestine and excessive bacterial growth; others explain diarrhea from changes in intestinal hormone secretion. Its clinical manifestations, in addition to the general manifestations of diabetes, the most prominent clinical manifestation of the disease is intermittent watery diarrhea, which occurs as few as 3-5 times a day and as many as 20-30 times a day. The diarrhea occurs mostly at night, and some patients have alternating diarrhea and constipation, or even intractable constipation. Most patients also have peripheral neuropathy, such as weakened or absent tendon reflexes, weakened or absent tactile, vibration and position sensations, reduced muscle strength and sensory numbness. Some patients may have abnormal autonomic function, such as urinary incontinence, impotence, excessive sweating, etc. Based on the above clinical manifestations, combined with laboratory tests and exclusion of other diseases causing intestinal dysfunction, the diagnosis can be confirmed. The treatment of diabetic enteropathy is divided into two aspects: Western medicine treatment and Chinese medicine treatment. Western medical treatment, for which there is no specific treatment, is based on effective diabetes control, improvement of autonomic nerves, symptomatic treatment and relief of symptoms. Drugs to improve the function of the vegetative nerves such as vitamin B1 and B12, etc. In patients with severe diarrhea, scopolamine and compound phenylephrine can be tried.
