Many hypertensive patients have elevated fasting blood sugar sooner or later, but the elevation is small, between more than 5.9 – less than 7.2mmol/l, it is likely to develop into type II diabetes, and it is possible to restore normal blood sugar with good treatment. So at this time, we should pay great attention to the control of blood sugar, first of all, change the diet, try to avoid sweet food and reduce the amount of food; at the same time, we should adjust the antihypertensive drugs, not to use drugs that have an impact on glucose metabolism, such as β-blockers, diuretics; choose drugs that have a protective effect on the pancreatic cells, such as ACE or ARB, rather than the other way around.
