The causal relationship between diabetes mellitus and gastric dysfunction and its pathogenesis are not well understood, but are generally considered to be related to autonomic neuropathy. Patients with diabetes mellitus, especially those with long duration of disease, are often complicated by nerve damage, and the autonomic nerves of the stomach can often be involved, resulting in hypogastric function and delayed emptying. Diabetic patients are often associated with gastric dysfunction and abnormal gastric acid secretion, but do not necessarily present with clinical symptoms. One of the common symptoms is abnormal gastric motility, which is firstly manifested by delayed gastric emptying and reduced or lack of peristaltic waves. barium X-ray examination may reveal that barium stays in the stomach for more than 6 hours after swallowing barium. In some cases, nausea and vomiting can appear suddenly and are often difficult to control. Delayed gastric emptying can affect the control of diabetes, with food retention in the stomach and delayed absorption in the small intestine. Hypoglycemic reactions can occur in patients treated with insulin, so gastric emptying function should be noted in diabetic patients with difficult-to-explain hypoglycemic reactions. The second is abnormal gastric mucosa. In diabetic patients, gastric acid secretion is reduced, the mucosa is atrophic, and the incidence of ulcers is low, but bleeding and perforation after ulcers occur is not uncommon. The diagnosis of diabetic gastric disease is mainly based on the history of diabetes and the clinical manifestations of the upper gastrointestinal tract, combined with relevant examinations, the diagnosis is not difficult to determine. For example, gastrointestinal imaging can show gastric dilatation, reduced or absent peristalsis, delayed emptying, and food can be retained in the stomach 12 hours after meals; nuclear method and gastric kinetic examination can understand the emptying ability of the stomach; gastroscopy can understand gastric peristalsis and gastric mucosa. The treatment of this disease includes both Western medical treatment and Chinese medical treatment. Western medicine treatment: There is no specific medicine for diabetic gastric dysfunction. The principle of clinical treatment is to actively control diabetes. The treatment of digestive symptoms is mainly symptomatic. Some people advocate that vitamin B1 and B12 should be given for the pathogenesis of gastric autonomic neuropathy, and drugs to promote gastric emptying can be tried such as gastroflucan and morpholine. Chinese medicine treatment: According to the clinical manifestations, it mostly belongs to the category of vomiting in Chinese medicine. The main pathogenesis of vomiting is that the disease is prolonged, from the yin to the yang, the spleen yang is deficient, the fluid does not work, the water is gathered as drink, and the stomach qi is blocked; or the yang is deficient, the cold is generated from within, and the stomach yang is not promoted. The treatment is divided into 1. Weakness of spleen yang: the main manifestations are stuffiness and discomfort in the stomach, vomiting clear water, dizziness, palpitations, white slippery tongue coating and sunken slippery pulse. The treatment is to warm Yang, dissolve water, harmonize the stomach and stop vomiting. The formula is Xiao Hanxia combined with Ling Gui Zhu Gan Tang (Hanxia, ginger, Poria, Gui Zhi, Licorice, Atractylodes, etc.), such as cough and asthma, can add almonds, Hou Pu to benefit the gas and calm asthma, such as vomiting more than, can add sand and stomach rebellion. 2, the stomach cold Qi rebellion: the main manifestations of the face is white, food into the vomit, sometimes made and sometimes stopped, or head dizziness pain, tiredness and weakness, thirst not want to drink, loose stools, the limbs are not warm, the tongue light coating white, the pulse is slow and weak. The treatment is to warm the middle and stomach, lower the rebellion and stop vomiting. The formula is Wu Zhuyu Tang (ginseng, jujube, Wu Zhuyu, ginger) or Ding Yu Li Zhong Tang (clove, Wu Zhuyu, ginseng, dry ginger, Atractylodes macrocephala, licorice). For those who vomit immediately after eating and cannot take medicine, acupuncture can be used.
