Both hyperglycemia and hypertension are serious, but hyperglycemia is more serious than hypertension because the damage to blood vessels is much higher than the damage to blood vessels. Although hypertension cannot be completely cured, it can be controlled within a stable range by insisting on taking antihypertensive drugs for a long time. Although hyperglycemia can be controlled by insulin or oral hypoglycemic drugs, hyperglycemia is actually a metabolic disease, and even if the blood sugar is controlled within the normal range, the damage to blood vessels still exists, but the damage can be less if the blood sugar is controlled smoothly. Moreover, the treatment of hyperglycemia is very long, and if a certain drug is applied to treat hyperglycemia, long-term application is likely to produce drug resistance.
