The feeling of always having to urinate and not being able to pass much urine is medically known as frequent urination. There are many causes of frequent urination, the common ones are: a. Infectious diseases, most commonly acute and chronic cystitis in women, due to inflammatory stimulation causing congestion of the bladder mucosa, producing the urge to urinate, and no obvious urine in the bladder, so there will be a feeling of urination, but not much urine discharge. In this case, oral or static antibiotic treatment is needed to relieve the symptoms. Second, urinary tract obstruction disease, most commonly in older men with prostate enlargement, produces urination due to more residual urine in the bladder. However, the obstruction of the urinary tract causes the urethral pressure to rise, resulting in difficulty in urination, which means that the symptoms of frequent and urgent urination will occur. If you have such symptoms, you will need medication or surgery.
