Prostate surgery usually refers to the surgical treatment of prostate enlargement. If the recovery after surgery is good and there is no discomfort of bloating and vomiting after drinking water, it is appropriate to drink more water. However, you should not drink too much water to avoid water intoxication and so on. Drinking more water can ensure that there is enough urine, which can flush the urethra, which is conducive to diluting the concentration of urine, preventing the production of urinary tract infections, preventing urinary tract stones and so on, which is good for the body. At the same time, the postoperative diet of prostate enlargement surgery should be light, do not eat too spicy, cold, stimulating food, eat more fresh vegetables and fruits. Patients should quit smoking and alcohol, and avoid heavy labor to avoid postoperative bleeding. After the prostate surgery, it is recommended to have regular checkups, and if there are any uncomfortable symptoms, they need to be diagnosed and treated under the guidance of a professional doctor.
