Diabetes is prone to complications of gastrointestinal diseases People are usually most concerned about the complications of diabetes with cardiovascular, nephropathy and neurological diseases, but not much is known about the gastrointestinal diseases that diabetes is also prone to, and the symptoms that appear are often ignored. In a study of 126 diabetic patients, 40 cases had gastrointestinal manifestations, mostly showing: difficulty in swallowing, burning sensation in the stomach, reflux after eating, bloating or diarrhea after eating, and so on. After barium meal or gastroscopy, it was proved that some of them had combined gastrointestinal diseases such as superficial gastritis, atrophic gastritis, gastric sinusitis or gastric ulcer. Experts believe that the gastrointestinal manifestations of diabetes may be related to factors such as endogenous insulin deficiency, which hinders glucose phosphorylation and leads to elevated osmotic pressure within nerve cells, causing gastrointestinal nerve conduction disorders. The gastrointestinal manifestations of diabetes mellitus are not related to gender, but to age and disease duration, i.e., older age and longer disease duration predispose to the development of gastrointestinal symptoms, and these patients have more severe vascular and other lesions. Gastrointestinal symptoms are more pronounced in patients with poorly controlled blood glucose levels and low insulin levels. When diabetes is complicated by gastrointestinal symptoms, blood glucose should be controlled along with symptomatic treatment with medication.
