Why do elderly hypertension always use diuretics, and can drinking less water produce the same effect?

Because the kidney function of the elderly is not very good, their own excretion function will also be reduced. Therefore, in daily life, we often see the phenomenon of leg edema in the elderly. Diuretics have dual functions in medicine, which can not only lower blood pressure, but also discharge excess water from human body. Therefore, diuretic antihypertensive drugs can kill two birds with one stone for elderly hypertensive patients, so diuretics are mostly chosen when choosing antihypertensive drugs. Drinking less water does not lower blood pressure, because blood pressure has nothing to do with drinking water. The hypotensive effect of diuretics is mainly based on its sodium excretion, so even if the amount of water is reduced, the blood pressure of human body cannot be lowered.

In medicine, there are many kinds of drugs for treating hypertension, and diuretics and antihypertensive drugs are only one of them. The most representative are hydrochlorothiazide tablets and indapamide tablets, both of which are diuretics and antihypertensive drugs. The price of these drugs is also very cheap, the price of each tablet is only about 1 cent, so this antihypertensive drug is very popular among middle-aged and elderly people. In addition to being cheap, diuretics and antihypertensive drugs are also very suitable for elderly patients with hypertension. Diuretics can not only play a drainage role, but also discharge excess sodium ions in the human body, thus lowering blood pressure and achieving the effect of lowering blood pressure.

Patients with hypertension are actually divided into two types. One is patients with hypertension, which means that their systolic and diastolic blood pressure are higher than normal. The second type is patients with hypotension and hypertension, which means that the diastolic blood pressure of patients is higher than the normal value of human body. These two kinds of hypertension patients have different populations.

Hypertension patients are mainly middle-aged and elderly people, and hypertension patients are mainly young people around 30 years old. In addition, the antihypertensive drugs they use are also obviously different. For example, diuretics are the main antihypertensive drugs for middle-aged and elderly people, while valsartan is the main antihypertensive drug for young hypertensive patients. Finally, patients with hypertension and hypotension are more difficult to treat than patients with hypertension. In a word, no matter what kind of hypertension, it will pose a serious threat to our health. In order to prevent the occurrence of hypertension, we must pay more attention to diet and develop a diet habit of low sugar, low salt and low fat.
