The number of people with diabetes is increasing worldwide, and China is now the number one country with diabetes, with one tenth of the total population with diabetes.

How terrible is diabetes? 1.Urinary ketoacidosis Diabetic patients under the action of various triggers, insulin is obviously insufficient and gluconeogenic hormones are inappropriately elevated, resulting in a syndrome of pathological changes such as hyperglycemia, hyperemia, ketonuria, dehydration, electrolyte disorders and metabolic acidosis. 2.Osmolar non-ketotic diabetic coma One of the serious acute comorbidities of diabetes mellitus, characterized by extremely high blood glucose without obvious ketoacidosis, dehydration, increased plasma osmolality, progressive impairment of consciousness, and high mortality. 3, urinary disease lactic acidosis A clinical syndrome caused by abnormal biochemical changes of persistently high blood lactate and low PH (<7.35) from different causes, with serious consequences and high mortality. 4, skin infections Diabetic skin infections such as ringworm, ringworm of the fingernails, ringworm of the feet and boils and carbuncles and other purulent infections are common, sometimes leading to sepsis, and some can cause gangrene of the lower extremities, manifested as pain in the lower extremities, abnormal sensation and intermittent claudication, skin ulcers, gangrene of the extremities, etc. 5, urinary disease and tuberculosis, especially pulmonary tuberculosis, once the disease, expanding rapidly, spreading widely, the lesions are mostly exudative dipyrone pneumonia, easy to become cavities, the incidence is 3 to 5 times higher than normal. It fluctuates with the control of tuberculosis. 6, urinary tract infections, including pyelonephritis, cystitis is common, sometimes with fungal vaginitis, infection is not easy to control, must be carried out at the same time with strict control of diabetes mellitus, in order to obtain better results.
