A glass of baking soda water may sound like a simple kitchen remedy, but claims that it can “reset” damaged kidneys in three hours are not supported by medical evidence.
Baking soda (sodium bicarbonate) does have legitimate medical uses in certain situations. Doctors may prescribe it to some people with chronic kidney disease who develop metabolic acidosis. However, this is a medical treatment that requires appropriate testing and dosing—it is not the same as drinking a homemade baking-soda mixture.
Why Baking Soda Is Sometimes Discussed With Kidney Disease
Healthy kidneys help regulate the body’s acid-base balance. In some people with advanced chronic kidney disease, the blood can become too acidic.
A healthcare professional may prescribe sodium bicarbonate in selected cases to help correct this problem.
That does not mean that baking soda repairs damaged kidney tissue or restores kidney function within hours.
Why You Shouldn’t Experiment With Large Amounts
Baking soda contains a substantial amount of sodium. Taking too much can potentially contribute to:
- Increased sodium levels
- Fluid retention
- Increased blood pressure
- Swelling
- Electrolyte disturbances
- Metabolic alkalosis
These problems can be particularly concerning for people who already have kidney, heart, or blood-pressure problems.
