How can i lose only 2 pounds when taking my first diuretic? thought i had more water weight than that.

Diuretics: Diuretics are not effective medications for weight loss. They are intended for persons who have conditions that cause them to retain excess fluid, such as certain heart or kidney problems. If a person without these problems takes diuretics, what happens is that the diuretics pull fluid out of the circulation system, making you feel faint and dizzy, and then the fluid comes right back.
