Does holding urine cause back pain? What causes back pain from holding urine?

Holding urine is a very bad habit, which may lead to urinary tract infection in severe cases. Some people often hold urine because they are too lazy to get up to urinate. Over time, this causes back pain. What is the reason for back pain when holding urine?

Dangers of holding urine

1. Holding urine affects the normal regular urination function, causing urine to remain in the bladder for too long, increasing the chance of bacterial growth and reproduction.

2. Due to holding urine, the pressure in the bladder increases, making it easy for bacteria to ascend along the ureter and cause pyelonephritis.

3. Frequent holding of urine causes the bladder to expand and remain full for a long time. Over time, the elasticity of the bladder wall decreases, the pressure receptors become blunt, and the bladder contraction force decreases, resulting in an increase in residual urine in the bladder after urination, and even urinary retention.

Causes of back pain due to urine retention

It may be caused by urinary tract infection. Urinary tract infection refers to urinary tract inflammation caused by pathogens invading the urinary tract mucosa or tissues. According to the site of infection, urinary tract infection can be divided into upper urinary tract infection and lower urinary tract infection. The former is pyelonephritis, and the latter is mainly cystitis.
