- What's a Diuretic?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I have been taking a medication for many years, called a diuretic.
- I know it is a water pill, but that's all. Recently you write that we should
- ask questions about our medications, so I am asking you: what's a diuretic?
-
- ------------------------------------------------------------------------------
-
- ANSWER: I think I suggested you ask your doctor about medications, but if you
- are asking me, I am happy to be your doctor, at least for now. Simply put, a
- diuretic is a medication the increases the production of urine. Our kidneys
- are in charge of that function and manufacture urine in a two step process.
- The first step is to "filter" the blood through the clump of capillaries and
- tubules that form a structure called a "glomerulus". This produces a liquid
- that passes through the tubules of the kidney to reach the main tube that
- passes to the bladder (ureter). As the liquid passes through the tubules, new
- chemicals are excreted into the liquid, while some precious chemicals and
- water itself is reabsorbed back into the body. The final fluid that passes
- down the collecting ducts is called urine. The structure that includes a
- glomerulus, the tubules and the duct is termed a "nephron" and is the basic
- anatomical and physiological structure that kidneys are made of. Now if you
- have that all clear, I can describe just how diuretics work. They may either
- increase the rate at which the glomerulus works, producing more basic fluid,
- or they may decrease the reabsorption that takes place in the tubules. Either
- action results in the production of more urine. Different chemicals that are
- used as diuretics act on different parts of the nephron system, and so
- physicians choose carefully, prescribing the one that is best for their
- patient's condition. Diuretics may be used to prevent or eliminate swelling
- (edema), control hypertension, and treat heart failure. The next question to
- ask your doctor is "What am I taking this medicine for?" Sorry, I can't
- answer that one for you.
