Unfortunately, Lasix is the modern equivalent of bleeding, cupping and leeches. In the old says, these techniques were used to drop and patient's blood volume and thereby alleviate swelling and congestive heart failure. Poor George Washington was bled to death in treatments for his "pleurisy"
Lasix is a drug which temporarily poisons the smallest functioning part of the kidney , the ascending tubule of the loop of Henle of the kidney tubules where it stops the normal re-absorption of salt , potassium and water from the filtered fluid in the causing a huge increase in the output of urine (diuresis). Prolonged use of Lasix (Furosemide) is associated with significant losses of sodium, chloride, potassium and body water and other minerals.
Lasix is best used to treat excessive fluid accumulation caused by congestive heart failure, liver or kidney failure but should NOT be used to reduce post-surgical swelling. Doing so affects the fluid and salt balance and can dangerously lower potassium risking potentially fatal heart rhythm abnormalities, serious metabolic disorders. But, despite all of these risks once the patient stops taking it and drinks, the swelling reappears. Lasix has also been misused to lose weight - it does not really work this way either.
Surgical swelling will subside with time. It will NOT be hastened in with Lasix or other diuretics.
