The first thing to consider is the increase in the number of urination due to drinking a lot of water or not paying attention to abdominal warmth, resulting in the total feeling of urination, while the cold stimulation caused by abdominal distension and pain, generally enhance warmth and control the amount of water can be self-relieved. Next, consider the urinary system diseases: 1, inflammation: such as cystitis, urethritis, etc., mostly due to bacterial infections, due to inflammation stimulation of the mucosa caused by edema, resulting in increased sensitivity of the mucosa, a small amount of urine can produce the desire to urinate, causing frequent urination, but also urgent, painful urination, can be accompanied by the emergence of waist, abdominal distension and pain. Generally, we need to improve the urinary routine, and urine culture, to identify the causative bacteria, and then apply sensitive antibacterial drugs for treatment, and pay attention to maintain a good life and diet; 2, stones: such as bladder stones, urethral stones, bladder stones are common in the narrowing of the urinary tract, while the increase in the concentration of oxalic acid in urine can lead to stone formation, if the stone embedded in the bladder neck can cause urinary retention, so that you feel that there is always the urge to urinate, and at the same time can If the stone is embedded in the bladder neck, it can cause urinary retention, which can make you feel like you always have the urge to urinate, and at the same time, it can cause abdominal distension and pain, which is most obvious when urinating, and can be treated with litholytic drugs or extracorporeal lithotripsy. In addition, when women have the above symptoms, they should also consider gynecological inflammation, as inflammation stimulates the small abdominal distension and pain, and there is always the urge to urinate; for older men, they should also consider prostatic hyperplasia, as the symptoms during the urinary storage period can be manifested as frequent urination, and the symptoms are more obvious at night, and at the same time, due to the reduction of effective bladder capacity, urinary retention can cause small abdominal distension and pain.
