vízhajtó

A vízhajtó, often translated as diuretic, is a substance that promotes diuresis, which is the increased production of urine. This leads to a reduction in the amount of extracellular fluid in the body. Diuretics work by affecting the kidneys' ability to reabsorb water and electrolytes, essentially flushing them out of the body.

There are several classes of diuretics, including thiazides, loop diuretics, and potassium-sparing diuretics, each with a different mechanism of action and potency. They are commonly used in medicine to treat conditions such as hypertension (high blood pressure), heart failure, edema (swelling), and certain kidney disorders. By reducing fluid volume, diuretics can lower blood pressure and alleviate the strain on the heart.

While generally safe and effective when prescribed by a healthcare professional, diuretics can have side effects. These may include electrolyte imbalances (such as low potassium or sodium levels), dehydration, dizziness, and increased urination frequency. It is important to use diuretics only under medical supervision and to follow dosage instructions carefully. Some natural substances are also considered to have mild diuretic properties, such as certain herbs and teas, though their efficacy and safety are not always as well-established as pharmaceutical diuretics.
