The growth of male prostate never stops.
It is said that it is never too old to learn, and the prostate is never too old to grow.
The prostate in male childhood is only the size of chestnuts. When the prostate of middle-aged and elderly people can grow to the size of an orange, it has also been seen clinically to be larger than an apple, more than 200g g g.
Therefore, prostate hyperplasia and prostate cancer are almost the inevitable fate of every elderly man. In the past, because of the short life span, the incidence of related diseases was less.
In the future of longevity and aging, the incidence of prostate diseases will be higher than most people think. Therefore, after men are over 60 years old, regular physical examination must be included in the relevant examination of prostate;

Alcohol can stimulate urination, and the core of "hangover" is hydration.
This is because alcohol can inhibit the secretion of antidiuretic hormone (ADH) by pituitary gland, which reduces the reabsorption of water by kidney, so urine will increase, so it has diuretic effect. Every intake of 1 ml alcohol can lead to about 4 ml urine excretion.
One of the causes of headache after hangover is dehydration of the central nervous system (brain and spinal cord) and nerve stretching caused by dehydration after drinking.
Therefore, try not to drink too much, and supplement a lot of water before and after drinking, which not only helps alcohol metabolism, but also quickly relieves discomfort. The core principle of all kinds of so-called "hangover soup" and "hangover drink" also lies in replenishing water.
The principle of action of antidiuretic hormone, alcohol inhibits the production of antidiuretic hormone, so it leads to a lot of urination and dehydration after drinking.

It's nice to hold your urine, bladder crematorium
Holding your urine will damage your bladder. This is not only bad for men, but also bad for women.
Urination is an unconditional reflex. Urine produced by the kidneys (renal tubules and collecting ducts) flows to the bladder. When the urine in the bladder accumulates to a certain amount, the bladder receptor sends out a signal, and the central nervous system receives the signal and feeds it back to the cerebral cortex for mediation, thus producing urination.
It is common to hold your urine when you are in a hurry, but if you hold it for a long time, it will be more than just "holding it".
When you hold your urine, the bladder will be blocked at the air outlet like a balloon, and the pressure on the inner wall will increase. In order to accommodate more urine, the bladder wall will also become thinner due to expansion.
It will also put pressure on the surrounding "neighbors":
Health hazards include:
1. Destroy bladder elasticity
If you hold your urine for a long time (more than ten years), it will lead to the decrease of the elasticity of bladder smooth muscle, which will easily lead to urinary incontinence or eventually disrupt the normal physiological reflex of urination.
In layman's terms, you can't pee if you have urine, and you always want to pee if you don't.
2. Induce infection
Urine stays in the bladder for too long, and if it is a patient with renal insufficiency, the chance of bacterial infection will greatly increase. Once urine returns to the ureter and kidney, the toxic substances in it will cause kidney infection, urinary tract infection, nephritis and even uremia.
3. Affect renal function
If the bladder is under high pressure for a long time, the contractility of the bladder will be
