Three highs, also known as high blood pressure, high blood sugar and high blood fat, may cause diabetes, arteriosclerosis, renal lesions, coronary heart disease, myocardial infarction, cerebral infarction, cerebral hemorrhage and so on. 1. Diabetes mellitus: long-term three highs will induce sugar metabolism disorders, thus causing endocrine diseases such as diabetes mellitus. 2. Arteriosclerosis: due to abnormal blood lipids, it is possible to cause the increase of vascular wall deposits, thus leading to arteriosclerosis. 3. Renal lesions: long-term hypertension may cause hypertension, sexual kidney damage, causing renal lesions. 4. Coronary heart disease: high blood pressure and high blood fat can easily cause coronary artery atherosclerosis, thus causing coronary heart disease. 5. Myocardial infarction: if the three highs are not regulated and treated in time, resulting in coronary artery sclerosis and stenosis, may cause myocardial infarction and other diseases. 6. Cerebral infarction, cerebral hemorrhage: long-term stimulation of three highs will cause cerebral vascular abnormalities, resulting in cerebral infarction, cerebral hemorrhage and other diseases. Suffering from three highs need to go to the hospital as soon as possible for examination and treatment, and follow the doctor’s instructions for treatment.
