Is it okay to hold your urine the night before a pregnancy ultrasound?

In fact, many people often have the problem of holding urine. Especially in winter or autumn, the weather is often not as hot as in summer. So many people fell asleep when they went to bed. Even if you have to pee. But I don't want to get up to pee anymore. People at this time are often more prone to cystitis, and the same is true for pregnant women. Is it good to hold urine at night when pregnant?

1. When 200cc of urine accumulates in the bladder, people will begin to feel the urge to urinate. If you do not urinate at this time, the bladder still has storage space. However, when it continues to accumulate to 500-600cc, the bladder will become over-inflated and the muscles that control urination will swell and relax. For people who do not often hold their urine, these muscles will quickly regain their elasticity. However, if you often force yourself to hold your urine, these muscles will become loose, making it easy for you to suffer from frequent urination and urinary incontinence in the future.

2. When you hold your urine for a long time, you will experience lower abdominal pain, frequent urination, and a feeling of incomplete urination when you urinate for the first time. This is because the over-full bladder compresses the nerves in the bladder that control urination. If you hold your urine frequently or continuously, it is very likely to cause permanent damage to the neurons and may also cause urinary incontinence in the future.

3. The bladder originally collects urine that has been metabolized by the human body. The products want to be discharged from the body, so urine contains a large number of bacteria. Fortunately, the mucous membrane inside the bladder has a certain antibacterial effect. Under normal circumstances, these bacteria will be flushed out of the body due to urination. However, if urine is held back for a long time, the resistance of the bladder mucosa will be reduced, giving bacteria an opportunity to cause urinary tract infection. In severe cases, it will reach the bladder and kidneys, causing symptoms such as acute cystitis and hematuria.

4. In addition, some people will experience urine reflux during acute cystitis. When the bacteria-laden urine flows back into the kidneys, it may cause acute pyelonephritis and hydronephritis, which will not only affect the function of the kidneys, but may also lead to renal failure or even dialysis in the future.

In fact, holding urine at night during pregnancy is a very bad behavior. And it needs to be changed. In fact, many pregnant women will have the problem of frequent urination when they reach the late stage of pregnancy. If you don't want to get up and hold your urine, it will often lead to cystitis.
