The high cystitis season is coming again! You have to hold your urine when you are busy, and you don't even have time to go to the bathroom? It's hot, you sweat a lot and don't drink enough water. If you still have bad habits such as holding your urine, beware of cystitis coming to you! In hot summer, when the body sweats to regulate body temperature, if water is not replenished in time, the urine volume will start to decrease and the urine concentration will increase, so that the urethra can not be flushed through urine, which will easily lead to a large number of bacteria breeding in it, leading to cystitis. Can holding urine lead to cystitis? Bladder has the function of resisting bacteria. Under normal circumstances, the human body should be able to destroy invading bacteria when urinating, but bacteria may also remain in the bladder because they attach to the urethra or bladder wall or grow too fast. If you hold your urine for a long time, it will lead to bladder bloating. If the bladder expands and cools for a long time, it will reduce the blood flow in the bladder, thus reducing the resistance of the bladder and making it easier for bacteria to multiply in the bladder. In addition, when you are stressed or tired, you are more likely to suffer from cystitis. An article written by practical nurse Broussy, who is registered in the United States, points out that for people with healthy urinary organs, holding urine will not cause danger, but it may cause discomfort. In addition, for patients with overactive bladder, holding urine is also one of the important trainings to exercise bladder function. However, for the following people, holding urine may increase the risk of urinary tract infection and kidney disease: prostatic hypertrophy, neurogenic bladder dysfunction, kidney disease, urinary retention, and holding urine by pregnant women itself is not the cause of urinary tract infection and inflammation. However, if there is no fixed time to urinate and empty the bladder, bacteria will stay in the bladder more easily and even multiply rapidly. When these bacteria invade the urinary tract, it may cause urinary tract infection and inflammation. The National Institute on Aging also suggests that you should urinate every 3-4 hours, because holding urine for too long may lead to bladder muscle weakness and increase the possibility of bladder infection. Symptoms of cystitis According to MedlinePlus, the health education information website of the National Library of Medicine, the symptoms of cystitis include: turbid urine, or blood in urine with a strong smell or odor, and low fever (not all patients have this symptom). Pain or burning sensation when urinating, compression and spasm in the center of abdomen or lower back. There is often a strong sense of urination, even after urination. In addition, for the elderly, mental change or confusion may be the only sign of latent infection.
