Some people like to hold urine very much, especially at night, and sleep so well that they prefer to hold urine rather than get up to eliminate it. Many people know that holding urine is a bad habit, especially after many people suffer from chronic renal failure, this situation is firmly not to do. Then why can’t you hold urine in chronic kidney failure, listen to the answer of experts. Urine is the product of kidney metabolism, the kidneys to produce urine to regulate the excess water in the body, excrete the metabolic waste and toxins produced by the body’s metabolism. Every day, the water produced by diet and metabolism in the body enters the kidneys with the blood flow. There are many “filters” called glomeruli in the kidneys. The glomeruli are specialized in filtering water and metabolic waste. When blood flows into the “filters,” the excess water in the blood is filtered out along with the metabolic wastes in the body to form urine. Urine enters the bladder through the ureter and is stored in the bladder, and when it reaches a certain volume, the sensation of urination occurs. Urine is a metabolic product of the body, most of which is not needed by the body, and it is constantly being formed. If you hold urine, more and more urine will be retained in the bladder, and the bladder will increase in size, leading to damage to the bladder muscles due to expansion. Some people hold urine for a period of time, even if the discharge will also feel pain in the abdomen, which is the reason that the bladder is not fully contracted after expansion. In addition, holding urine for too long, the pressure in the bladder increases, which is bound to damage the metabolic function of the kidneys to excrete waste, so that water and metabolic waste accumulate in the body, causing uremia, causing kidney failure and life-threatening. You should not hold urine in any situation except for a short period of time to do certain tests. Outdoor exercise increased, to timely replenish water, play the role of water on the urethra “flushing” to avoid bacterial reproduction; secondly, usually can not hold urine, once the frequency of urination, urinary urgency, painful urination and other symptoms, to promptly seek medical attention, to prevent urinary tract infection caused by acute pyelonephritis or long-term untreated eventually lead to the catastrophe of uremia. Again, pay attention to more rest, overwork may also trigger urinary tract infection, for people with cervicitis, trichomoniasis, mycotic vaginitis and other gynecological disorders to actively treat the original disease, and to actively treat chronic diseases that trigger urinary tract infection, such as diabetes. Finally, eat more fresh vegetables and fruits, avoid eating more greasy and spicy food, and adhere to physical exercise to strengthen the body’s resistance. The reason why chronic renal failure patients cannot hold urine is introduced to you here, you can also see that often hold urine is likely to cause chronic renal failure, so no matter what the reason is, try to hold urine less, so as not to bring serious impact on our health. In addition, once kidney failure occurs, timely and scientific treatment is the most important.
