Drinking more water and urinating more will increase the pressure on the kidney. Will drinking water hurt the kidney?

0 1 drinking water and drainage mechanism

First of all, the design of our human body is very exquisite. Under normal circumstances (no disease), our body has a perfect system to adjust the water intake and discharge of the human body.

The regulation of water mainly involves these organs of human body.

Brain hypothalamus osmotic receptor and drinking water center

In the hypothalamus of the brain, there is a chemical receptor called osmotic pressure receptor. They can feel the salt content in our blood. When the salt content is too high, they will tell the drinking water center in the brain that they feel thirsty and remind the body that they need to drink water. People will want to drink water and find water to drink.

When we are full of water, the salt concentration in the blood decreases, and then the osmotic pressure sensor feels that thirst disappears and people don't want to drink water.

If you drink too much water, the salt concentration will continue to drop. Our osmoreceptors tell our pituitary gland to reduce the secretion of hormones, thus increasing the discharge of urine. In experiments, scientists found that as long as the drinking center of hypothalamus is destroyed, animals (including humans) will not drink water, and they will not feel thirsty or want to drink water. When you stimulate this part with electric current, the animal will continue to drink water.

pituitary gland

Pituitary gland is the archduke tube of human hormones, which can secrete a variety of hormones. One of the antidiuretic hormones is called? Diuretic hormone?

Diuresis, as the name implies, is to promote the excretion of urine. Antidiuretic? Just don't let the urine out.

The use of antidiuretic hormone in pituitary gland can affect the urine output produced by kidney.

When you drink too much water, the secretion of antidiuretic hormone will decrease, so the amount of urine will increase, which will help to expel excess water from the body.

If the salt in the urine is too much or secreted too much, the water in the kidney will be secreted less. This is one of the reasons why eating too much salt often leads to high blood pressure. )

kidney

The kidney is an important organ for us to excrete water from the body. Every day, we excrete about 1600-2000ml of urine. At the same time, there are many wastes, such as uric acid, creatinine and other human wastes, which are also excreted through urine.

The antidiuretic hormone affects the urine output of the kidney.
