Geriatric diabetes is defined as diabetes mellitus in patients aged >60 years, including those diagnosed before age 60 and those diagnosed with diabetes after age 60. Its prevalence is as high as 23.9%. Geriatric diabetes has its own characteristics: 1. Most patients do not have the obvious “three more and one less” symptoms, or the symptoms are mild and seen as a normal manifestation of old age. Or many patients find diabetes because of complications, such as hypertension, heart disease, cerebral infarction, nephropathy, recurrent urinary tract infections, skin infections, eye disease, vulvar itching, gangrene of the lower limbs, peripheral neuropathy (cold hands and feet, numbness), gastroparesis (poor digestion) and so on. 2. Most of them are type 2 diabetes. However, because of old age, most patients have poor pancreatic islet function, so oral hypoglycemic drugs are not effective and often require treatment with insulin. 3, poor glycemic control, poor compliance with treatment, and many complications. Elderly people have aging organs, low immunity, and many elderly people have poor dietary control or dislike the trouble of insulin injection, so the treatment effect is poor and there are many complications. 4. Because some patients have difficulty in moving around, or do not want to follow up regularly, when the condition changes the treatment measures do not change with it, and more serious acute complications occur, such as diabetic non-ketotic hyperosmolar syndrome, or serious hypoglycemia, and life-threatening. The special features of the treatment of geriatric diabetes: 1. Drug therapy should start with small doses. Older people have poor tolerance, or combined with serious complications, so the starting dose should be small to avoid drug side effects. Insulin should also be started in small doses and adjusted slowly to avoid severe hypoglycemia. 2. The goal of sugar control can be relaxed appropriately. For patients with no complications, it can be strictly required and try to be consistent with non-diabetic patients. And patients with complex and heavy conditions and many complications can relax the requirements. A phrase is convenient to remember: “fasting five or six not away from seven, after meals eight or nine not away from ten”. 3. Strictly prevent hypoglycemia. Older people have poor ability to regulate hypoglycemia, and irregular life and unreasonable medication may lead to serious hypoglycemia and endanger life. Therefore, elderly patients are required to closely monitor blood sugar, live regularly and visit the hospital regularly to adjust the glucose-lowering program. 4. Pay attention to drug interactions. Elderly patients often take many kinds of drugs in combination with various chronic diseases, and many drugs have an effect on blood sugar. For example, beta-blockers such as betalactam can mask hypoglycemic reactions such as panic and sweating, while enhancing the hypoglycemic effect of sulfonylureas; diuretics such as hydrochlorothiazide have an effect on blood sugar when used for a long time; glucocorticoids and certain antidepressants can lead to an increase in blood sugar; ciprofloxacin and glibenclamide together affect liver function and increase the risk of hypoglycemia. 5, try to avoid large fluctuations in blood sugar. Large blood sugar fluctuations will accelerate the process of atherosclerosis, promote plaque formation, and lead to the development of diabetic complications. Therefore, it is necessary to monitor blood glucose 6-7 times a day, look for the cause when blood glucose fluctuates greatly, and try to avoid it. Daily regimen for senile diabetes: 1. Eat a balanced and reasonable diet. Eat less sweets, more vegetables, moderate amount of fruit, coarse and fine grains with. Only eat coarse food, afraid to eat eggs, meat and other perceptions are wrong, will lead to nutritional imbalance or poor, but not good for the body. 2, exercise regular moderate. Walking half an hour a day is the simplest and necessary, it is advisable to start activities about half an hour after meals, the general activity after the heart rate does not exceed “170-age” is appropriate. People with serious heart, brain and kidney complications should not be active. Take food with you when you go out to prevent hypoglycemia. 3. Keep your mood relaxed. Many elderly people are prone to emotional agitation and anxiety, and even develop into anxiety and depression, so if necessary, take antidepressants for a short time to improve the symptoms. Normally, you should establish a healthy lifestyle and maintain an optimistic and harmonious state of mind. Finally, I would like to talk about the medication for elderly diabetic patients. There are many kinds of glucose-lowering drugs, and the choice varies according to the patient’s condition. It is recommended that elderly patients should not blindly listen to the “experience” of others around them, not to mention the regularity of the drugs, what is suitable for others may not be suitable for you, and what is not effective for others may not be effective for you. So try to go to the regular hospital, let the doctor comprehensive consideration, systematic examination, targeted to you to develop an individualized optimal plan, in the scientific lowering of sugar at the same time maximum to avoid or delay the development of complications, improve the quality of life.
