can kidney failure cause shortness of breath
1 Shortness of breath â kidney failure is sometimes confused with asthma or heart failure, because fluid can build up in the lungs. 2  Ammonia breath or an ammonia or metal taste in the mouth â waste build-up in the body can cause bad breath, changes in taste, or an aversion to protein foods like meat.o acute renal failure means the kidneys have failed suddenly, often due to a toxin (a drug allergy or poison) or severe blood loss or trauma. Dialysis is used to clean the blood and give the kidneys a rest. If the cause is treated, the kidneys may be able to recover some or all of their function.
