3. Diuretics.
If you are taking diuretics, or water pills, more than likely your need to urinate more frequently is the result of those pills. Water pills are often used to treat several different medical conditions; examples include problems with the kidneys and liver, edema (swelling of the tissues throughout the body), as well as high blood pressure. Diuretics increase the production of sodium (salt) that the kidneys release into the urine.
The salt also removes water from your blood, which decreases the amount of fluid that flows through the arteries and veins; hence why diuretics are often used to treat high blood pressure. The increased amount of salt and water that are entering your urine leads to an increased need to urinate. If you have been prescribed diuretics and find that you’re urinating more often than usual, it is likely the result of the medication that you are taking.
