How much urine can the bladder hold

The bladder is a very important metabolic organ in the human body. If there is a problem with it, it will lead to very troublesome situations. Therefore, people must ensure that their bladders are not infected by bacteria, and they must not hold urine. Even if the bladder has a certain amount of urine storage, it cannot be held, otherwise it will cause some serious inflammatory diseases in their bodies.

The bladder has a limited capacity to store urine. The so-called "holding urine" means that the urine stored in the bladder exceeds the "physiological capacity of the bladder", but you consciously hold it back and do not discharge it.

People who hold their urine often want to hold it in, but are afraid that the urine will be discharged involuntarily and wet their bed or clothes. Therefore, they have a heavy mental burden. Holding urine for a long time can induce psychogenic enuresis. When they hear the sound of water or see the toilet, they can't wait to discharge urine. If you hold your urine for a long time, the bladder muscles will gradually become loose and weak, and the contraction force will weaken, which will then lead to phenomena such as difficulty in urination and slow urination.

A more serious harm of holding urine is that holding urine for a long time will cause the urine in the bladder and (or) the bacteria in the urine to flow back to the renal pelvis, causing reflux nephropathy and (or) pyelonephritis. Over time, it will lead to damage to the parenchymal structure of the kidney and even renal failure, which is especially common in children.

Holding urine for a long time is not good for health and can cause urinary system diseases. People have all had the experience of holding urine. Some do so because they cannot give up their personal hobbies, and some do so because they are unwilling to leave the "battlefield" of playing cards or chess. However, not being able to urinate in time when feeling the urge to urinate is very bad for health. As the saying goes, "running water does not stagnate." Normal urination can not only excrete metabolic products in the body, but also has a self-cleaning effect on the urinary system. When you hold your urine, the bladder swells, the blood vessels in the bladder wall are compressed, the bladder mucosa becomes ischemic, and the resistance is reduced. Bacteria will take advantage of the situation and grow and multiply rapidly, which can not only easily cause urinary system diseases such as cystitis and urethritis, but in severe cases it can also affect kidney function.

Holding urine can also cause physical and psychological tension, leading to higher blood pressure in patients with hypertension, arrhythmias and even angina pectoris in patients with coronary heart disease, which is tantamount to adding fuel to the fire for the elderly who already have cardiovascular and cerebrovascular diseases. Prostate enlargement is a common disease among the elderly. If you hold your urine for a long time, the already enlarged prostate will suffer even more.

In addition, holding urine will prevent toxic substances in the urine from being excreted from the body in time, prolonging the effect of carcinogens in the urine on the bladder, which can easily induce the occurrence of bladder cancer. According to a research report by American scientists, people who have the habit of holding their urine are 3 to 5 times more likely to develop bladder cancer than the average person. Therefore, holding urine is a very bad habit, and the elderly should develop the habit of urinating at regular times.
