Ckd patient with hyponatremia. is it safe to take 650 mg sodium bicarbonate with 40 mg lasix (furosemide) to prevent water retention? is sodium bicarbonate renoprotective?

Depends: Bicarbonate (sodium bicarbonate (sodium bicarbonate)) is not reno-protective. However, high acid levels in the blood affect heart function, muscle function and kidney function. Reducing the blood acid level (seen by a rising bicarbonate (sodium bicarbonate) level or pH level) improves muscle function including the heart which improves kidney circulation. It also allows the kidneys to better control potassium levels. You can help the process by avoiding sodas!

Hyponatremia: You need to have your physician (P) find out why you have hyponatremia (H). Some of its causes are salt losing disorders of the kidney, inappropriate ADH (vasopressin) secretion, Addison's disease, high glucose levels and diuretic abuse, amongst others. I would ask your P's advice before you take the drugs you mentioned. If you mistreat H, it will only get worse with potentially serious consequences. Good luck.

Nephrologist: Without knowing your levels of electrolytes,bun and creatinine, the question of sodium bicarbonate administration is difficult to answer. It's more common to use lasix (furosemide) for diureses but it can worsen kidney function. A nephrologist, who knows @ll your findings is best qualified to answer your questions which are complicated.
