Diuretics or "water pills" as they as sometimes know as, are drugs that increase the rate of urine flow. They increase the rate of sodium excretion from the body. Many people have notice that eating salty foods causes them to retain fluids, sometimes causing puffiness around the eyes or swollen ankles. Salt is sodium chloride. Sodium is the main determinant of the water volume outside of the cells or extracellular water. A diuretic that causes sodium to be lost in the urine decreases the volume of the extracellular water.
  When excess fluid accumulates in tissues or body cavities, problems can occur. For example, excess fluid that collects in the air sacs and tissues of the lungs, referred to as pulmonary edema, interferes with the ability of the lungs to provide adequate respiration and can be life threatening.
  There are several prescription diuretics available online. You may now obtain prescription antibiotics safely and easily online through "no prescription required" online pharmacies.
