Drinking a lot of water without urination, it is recommended to go to the hospital for further examination to clarify whether it is a disease condition, and then decide how to deal with it: First, it may be that the body itself is dehydrated, and at this time, drinking a lot of water has not replaced the water that has been lost, and at this time, urination will not occur. It is recommended to continue hydration appropriately and then observe whether urination occurs. If there is still no urination, it is recommended to go to the hospital for kidney function check, and if necessary, give diuretics for treatment, or take 1 tablet of tachyphylaxis orally, and observe whether urination increases immediately after oral intake. Secondly, if there is a kidney disease, it is recommended to go to the hospital for a kidney function test as it can appear that you are not urinating after drinking a lot of water. If kidney function abnormalities are diagnosed, it is recommended to use furosemide injection 20mg intravenously and observe whether the urine volume is restored. If it still does not recover, it is recommended to increase the dosage to 40mg of furosemide injection and then observe whether urination is restored. If there is a large amount of water stagnation in the body and there is a progressive rise in renal function, dialysis treatment is needed to release the metabolic waste and water from the body if necessary.
