When the body consumes more water, if there is no urination, it is possible that the body itself is suffering from dehydration. In addition, due to the high ambient temperature, the body loses too much water through the skin mucosa and oral mucosa, so there is a concentration of urine that does not trigger the nerve impulse to urinate. Other factors are caused by specific diseases in the human body, such as abnormal function of bilateral kidneys, and in acute renal failure, none of them will have significant urine filtration. Therefore, even if the body consumes too much water, there will be no urine discharge. Patients can have blood tests for blood creatinine and urea nitrogen levels to clarify the presence of the disease. Other factors are urinary obstruction problems, such as bilateral ureteral stones, urethral stones, urethral stricture, prostatic hyperplasia, neurogenic bladder and other diseases can cause the inability to urinate, resulting in a large amount of urine stored in the bladder, usually with symptoms of lower abdominal bulge, patients are advised to check the urinary ultrasound to clarify the disease.
