The three highs refer to high blood pressure, high blood sugar and high blood lipids. These three highs are extremely harmful to the human body and can accelerate the progress of atherosclerosis, which can cause coronary heart disease, angina pectoris, and even acute myocardial infarction and stroke and other cardiovascular and cerebrovascular diseases if poorly controlled for a long time. High blood lipids also tend to cause pancreatitis and fatty liver. The blood sugar control is not stable, and often this will induce diabetic nephropathy, so the three high for the human body is very harmful. During the day, we should improve our diet and lifestyle habits, including a low-salt, low-fat diet, regular work and rest, eating more fresh fruits and vegetables, and exercising to lose weight. For patients who are found to have abnormalities in these three indicators, they should be actively treated, especially elderly patients, who can take long-term preventive oral lipid-lowering drugs such as atorvastatin and rasulvastatin, which can not only lower blood lipids but also prevent the progression of atherosclerosis. Hypertension itself can accelerate the progression of atherosclerosis, and antiplatelet drugs, such as aspirin, can be applied in combination with antihypertensive drugs. Patients with abnormal blood sugar, for those who have been diagnosed with diabetes, should not only avoid eating, but also actively take oral hypoglycemic drugs, or subcutaneous insulin injections, in order to reduce or prevent complications.
