AIN has several causes:
AIN is more common in older adults. Your chances are also higher if you:
- Take certain medicines
- Have an infection
AIN may cause:
- Lower amounts of urine than normal
- A general feeling of illness—malaise
- Lack of hunger
- Nausea and vomiting
- Pain in your side
- Joint aches
- Low fever
- Blood in your urine (rare)
The doctor will ask about your symptoms and health history. A physical exam and urine tests may point to AIN. You may also have:
AIN care depends on the cause. For example, if medicine you take is harming your kidneys, your doctor will make changes. Care also helps other symptoms such as a rash or fever. AIN care may also involve:
- Antibiotics for bacterial infection
- Corticosteroids to reduce inflammation
- Dialysis —a machine works for your kidneys by filtering your blood
To help lower your chances of AIN, don’t take medicines you know cause kidney problems. Your doctor will find other medicines to help you.
