The consequences of not taking medication for diabetic patients need to be judged according to the actual situation, generally some diabetic patients after diet and exercise control, blood glucose after reaching the standard, generally will not cause adverse consequences, but by diet and exercise control after blood glucose still does not reach the standard, patients and not through drug treatment, may lead to heart disease, brain disease, kidney disease, retinopathy, diabetic ketoacidosis, etc. 1, heart disease: if the diabetic lesions involve the heart microvessels, causing capillary and pre-capillary small artery lesions, it will easily lead to myocardial necrosis, thus affecting the contraction function of the heart, and even endangering the life of the patient. 2, brain disease: if the diabetic lesions involve the cerebral vessels, it will easily cause the cerebral vessels to develop atherosclerosis, resulting in the loss of elasticity of the vessel wall and plaque formation, thus causing cerebral disease. This may lead to stroke, cerebral infarction, coronary heart disease, etc., thus endangering the lives of patients; 3, kidney disease: if the diabetic lesions involve the kidneys, it may cause metabolic disorders in the body due to high blood sugar, and lead to reduced glomerular filtration function, causing patients to have increased nocturia, proteinuria and other lesions, and in the long run, patients may develop into In the long run, patients may develop uremia or even kidney failure, which will have a greater impact on the safety of patients’ lives. In addition, if diabetic patients do not take medication, resulting in liver and kidney dysfunction caused by excessive accumulation of lactic acid in the body, resulting in lactic acidosis, will affect the normal metabolism of the body, serious cases can be life-threatening; 4, retinopathy: If diabetic patients do not take medication, lesions involving the retinal vessels, resulting in retinal lesions, will lead to vision loss, serious cases may be blind; 5, diabetic ketosis Acidosis: If diabetic patients do not take their medication or do not take insulin, it is easy to cause high levels of blood sugar running, and high levels of running blood sugar is a better medium for microorganisms, such as bacteria, viruses, fungi, mycoplasma, etc., which can lead to diabetic ketoacidosis in serious cases. Ketoacidosis is an acute complication of diabetes, and untimely resuscitation can cause death of patients; 6. Other diseases: If infection occurs in diabetic patients, it may can accumulate skin, and some patients may have secondary infection if not treated in time, and the infection will aggravate and cause sepsis, or lead to diabetic foot. Diabetic patients should follow medical advice to apply hypoglycemic drugs for treatment, such as glipizide, glipizide, etc., and to use them continuously, not to stop or intermittently use them on their own, so as not to cause significant fluctuations in blood sugar. In daily life diabetic patients can eat coarse grains, such as oats, buckwheat, etc., eat less food containing high sugar, such as honey, sugar cane, groundnuts, etc., and can increase exercise, including slow walking, to a certain extent can assist in controlling blood sugar.
