Forty-year-old women who love to urinate all the time may be physiological factors, but also may be the manifestation of certain diseases, such as infections, kidney disease, etc., should consult a doctor in time to identify the cause of the disease. 1. Physiological factors: Forty-year-old women recently always love to urinate, usually due to drinking too much water, the environment temperature is too low, and so on. If the patient usually drink too much water, the amount of urine will increase, and the number of times of urination will also increase; in the low temperature environment, the human body sweating is reduced, the excess water needs to be discharged through the urine, so the amount of urine increases. 2. Pathologic factors: (1) urinary tract infection: if only the number of urination increases, but the amount of urine is very small each time, it is usually due to the bladder, urethra and neighboring organs are stimulated by inflammatory substances produced by infections such as cystitis, urethritis and so on, which cause women to always urinate recently. (2) Kidney diseases: such as chronic nephritis, chronic pyelonephritis, or endocrine metabolic system diseases, such as diabetes mellitus, uremia, etc., can also cause women to urinate frequently. In addition to the above factors, other factors can not be ruled out. It is recommended that patients go to regular hospitals as soon as possible for examination, and give targeted treatment after the doctor clarifies the cause of the disease.
