1. Obstruction: An obstruction in the urinary tract, such as a kidney stone, enlarged prostate, or tumor, can prevent urine from flowing freely and lead to retention.
2. Nerve damage: Damage to the nerves that control the bladder muscles can disrupt the normal process of emptying the bladder, resulting in urine retention.
3. Medications: Certain medications, such as antihistamines, decongestants, and muscle relaxants, can interfere with bladder function and cause urine retention as a side effect.
4. Infection: Urinary tract infections (UTIs) can cause inflammation and irritation in the bladder, leading to difficulty in emptying the bladder completely and resulting in urine retention.
5. Weak bladder muscles: Weakness in the muscles of the bladder can make it difficult to fully empty the bladder, leading to urine retention.
6. Psychological factors: Stress, anxiety, and other psychological factors can affect bladder function and contribute to urine retention.
