Hypoglycemia in elderly diabetic patients is mainly the use of hypoglycemic drug overdose caused by, including excessive oral hypoglycemic agents, insulin use excessive, or other diseases due to the use of paracetamol, propranolol and other drugs to enhance the role of hypoglycemic drugs.
In addition, old age is often accompanied by diabetes have heart and kidney dysfunction, heart failure leading to an effective reduction of blood flow. Renal insufficiency of glomerular filtration rate so that lower hypoglycemic agents may lead to accumulation in the body. Regulating hormones and the function of the elderly poor, in the case of sugar, when sugar can not increase the secretion of hormones, and thus easy to hypoglycemia.
When the blood sugar to 2.5mmI / L or when the sympathetic nervous system can occur in response, expressed as a cold sweat, irritability, palpitations, tremor, pale, and so there is hunger, when patients drink a glass of water or eat some candy block, or a small amount of diet, these symptoms can be eased; If blood sugar continues to decline, it will have the symptoms of central nervous system, manifested as headache, drowsiness, coma, convulsions, etc.. If a further reduction in blood glucose can cause permanent damage to the central nervous system.
This shows that elderly people should pay attention to the prevention of diabetic hypoglycemia, patients learn to self-monitoring condition, their own urine sugar tests, conditional trace can be self-blood glucose monitoring device, to capture the fluctuations in blood sugar, especially in strict accordance with the doctor's advice to use and can not authorization to increase the drug dose, the volume of activities encountered temporary increase, or can not eat, or eat because of poor appetite decrease, the need for the timely adjustment of the dosage of hypoglycemic agents.
The initial patients taking hypoglycemic agents should be started from small doses, glibenclamide should be used with caution due to glibenclamide in the commonly used hypoglycemic agents is the role of the strongest, longest role of drugs in the course in the use of low - the highest incidence of blood glucose. Should also be noted that the elderly should not have to ask for their blood glucose to normal, the control standards in order to achieve an appropriate level of mitigation is appropriate, avoid overkill.
