Downside of Diuretics

Is there any harm in taking diuretics?

Dr. Brownstein's Answer:

Diuretics are widely prescribed medications that elevate the rate of urination. They also lower blood pressure and help the kidneys release excess fluid. They are very effective at these tasks.

In fact, diuretics can be life-saving therapies in cases of acute congestive heart failure, during which excess fluid accumulates in the lungs. However, long-term use of diuretics can result in nutritional problems.

That’s because diuretics also increase the body’s loss of magnesium, which is an incredibly important mineral for the heart. Any patient suffering from cardiovascular illness should have their magnesium level evaluated. If the level is low, they should supplement with magnesium, especially if they are prescribed a diuretic. I have found that intravenous magnesium therapies provide near-miraculous results on very ill cardiovascular patients.

Diuretics also cause depletion of calcium, sodium, potassium, and zinc, which is necessary for proper immune system functioning. Patients taking a diuretic should supplement with a multimineral.
