(CKD; Chronic Renal Disease)

The doctor will ask about symptoms and health history. A physical exam may be done. Blood and urine tests will be done to see how well the kidneys are working.
Other tests will be done to find a cause. You may need to see a doctor who treats kidney diseases.
There is no cure. The goal of treatment is to prevent or slow damage and manage problems. Options are:
The doctor may advise stopping or changing any medicines that hurt the kidneys.
Medicines may be given to:
- Control health problems that hurt the kidneys, such as high blood pressure and diabetes
- Manage problems caused by CKD, such as swelling, nausea, or feeling tired.
The doctor may advise:
- Not smoking
- Dietary changes
- Regular exercise
People with severe CKD may need:
