Answer:
A. Kidney malfunction that causes abnormally high blood volume
Step-by-step explanation:
There are several reasons why you may have kidney failure, but beyond the cause you should take care of your physical health. The loss or insufficiency of renal function can cause problems in the body, such as:
- Anemia
- Heart problems
- Poor nutrition
- High blood pressure
- Cholesterol
- Mineral and bone problems
- Depression
They can be treated to help them not get worse. Keep in mind that kidney failure does not occur suddenly and that some of these problems may have started long before your kidneys failed.
