Symptoms

Fatigue

Fatigue can signal many things. Here are some tips to help you decipher why you're wiped out and to regain your energy.

Tests and diagnosis

CT scan

A CT scan is an imaging test that uses X-rays to produce detailed images of the inside of your body.

Kidney biopsy

A kidney biopsy — removing a small piece of kidney tissue for viewing under a microscope — helps with diagnosis and treatment of kidney problems.

Ultrasound

Ultrasound imaging uses high-frequency sound waves to create images of structures in your body.

Urinalysis

Urinalysis can be used to assess your overall health, detect a wide range of disorders, or monitor a medical condition or treatment.

Treatments and drugs

Allergy shots

Regular allergy shots may not be your idea of a good time. But they're generally safe — and might provide the long-term allergy relief you need.
