As the quality of life improves and eating habits change, more and more people are falling into the “sweet spiral” of diabetes. Regardless of the type of diabetes, it has its own pathogenesis and does not just happen all of a sudden. Some people who have early symptoms of diabetes don’t think they have it and regret it when it is diagnosed. The progression of diabetes is rapid. Type 1 diabetes goes through an incubation period when the pancreatic islets are attacked by a virus, and then suddenly develops when the autoimmune system is destroyed. The earliest stage is the “high-risk period” of diabetes. If you don’t pay attention during this period, your blood sugar will easily rise further and you may develop to the final stage and become a diabetic. ”Many people know that diabetes has the typical symptoms of “three more and one less”, i.e., polyuria, drinking and eating more, and weight loss. If these symptoms have already appeared, it means that the best time for diabetes prevention and treatment has been missed, and various complications are about to follow. Early diabetes or mild diabetes often does not have typical symptoms, and there is a wide range of symptoms due to different blood glucose levels in each individual. Early diabetes symptoms are usually manifested in the skin, vision, sleep disorders, etc.: Dry, itchy skin If the skin is often dry and moisturizers do not help, it is time to consider whether it is the effect of blood sugar. Due to the stimulation of the increased concentration of urine sugar, which affects the blood circulation, it will make the human skin dry, and the dryness will in turn cause itching of the skin. In many diabetic patients, the itchy areas are concentrated in the hands, feet and lower legs, and in women there is often vulvar itching. Changes in vision Changes in vision are also an early symptom of diabetes. Elevated blood sugar can cause changes in body fluids, leading to unstable vision. Some people’s vision becomes better or even do not need glasses, while others have poor vision and blurred vision. Sleep disorders A large percentage of people with type 2 diabetes have mild or moderate sleep breathing disorders, and most of them manifest as sleep apnea. People who feel tired and sleepy during the day and snore excessively at night are advised to have their blood glucose levels tested. For people with a family history of diabetes, obesity, metabolic abnormalities and other people at risk for diabetes, they should pay attention to the early symptoms of diabetes and do as much early screening as possible.
