How can I safely use a fleet enema for constipation if I have chronically low potassium?

Will prednisone 10mg for 2 weeks cause low potassium? I have chronically low potassium but doc isn't worried??

Will prednisone 10mg for 2 weeks cause low potassium? I have chronically low potassium but doc isn't worried??

Unlikely: Prednisone can lower the potassium concentration in part by causing fluid retention and dilution of the serum potassium. However, the problem is dose/duration dependent, so a short course of a low dose of prednisone is unlikely to cause a problem. You don't mention that you're on a potassium supplement, but, if you are, you certainly need to continue it. ...Read more

Severely constipated but I have chronically low potassium & a heart condition. Is there any way that I can safely administer myself an enema?

OK to Administer BUT: Heart condition and low pottasium is not a contraiindication to give yourself an enema.But chronic constipation needs to be treated with diet modification by increasing fiber in diet with combination of fruits, vegetables, whole grains and increased fluids. If that does not work you may use a stool softener with or without a laxative, suppsitories if needed. And some people need prescription medicatio ...Read more

What could be the cause of chronic dehydration with slightly low potassium and sodium? I drink 90oz of water a day and put salt on almost all my food.

Fluid balance: The explanation may be complex. Albuterol in high doses can cause low blood potassium. Otherwise, if you are drinking over 90 oz fluid per day and adding salt, and are still appearing dehydrated to your practitioner, then you must be losing fluid and some Na and K from your body somewhere. Possibilities are GI, skin, or kidneys. Some kidney dz cause just that: fluid loss, Na loss, and K loss. ...Read more

I have a low potassium problem and kidney stones problem. Is my hypokalemia the cause of my kidney stones? Or the other way?
