What Are Kidney Disorders?
Kidney disorders are conditions that affect how the kidneys work. Your kidneys play an important role in filtering waste from the blood, balancing fluids, and helping control blood pressure.
Kidney disorders can develop for many reasons. Common causes and risk factors include:
- Diabetes
- High blood pressure
- Infections
- Autoimmune conditions
- Family history of kidney disease
- Kidney stones or urinary blockage
- Long-term use of some pain medicines
- Smoking
- Inherited conditions such as polycystic kidney disease
Some kidney problems develop suddenly, while others happen slowly over time. Early care can help protect kidney function and support your overall health.
Symptoms
Kidney disorders can cause a variety of symptoms depending on the condition and how advanced it is. Some people may not notice symptoms in the early stages.
Common symptoms may include:
- Swelling in the legs, feet, hands, or face
- Feeling tired or weak
- Changes in urination
- Blood in the urine
- High blood pressure
- Nausea or loss of appetite
- Pain in the back or side
- Trouble concentrating
- Shortness of breath
How Is It Diagnosed?
Healthcare providers use several tools to evaluate kidney health. Your provider will review your symptoms, medical history, and perform a physical exam.
Testing may include blood work to measure kidney function, urine tests to check for protein or blood, and imaging studies such as an ultrasound or CT scan. In some cases, a kidney biopsy may be recommended to better understand the cause of the problem.
How Is It Treated?
Treatment depends on the type of kidney disorder and how severe it is. Many people can manage kidney disease with lifestyle changes, medications, and regular monitoring.
Treatment may include:
- Managing blood pressure and blood sugar
- Following a kidney-friendly diet
- Taking medications to treat underlying conditions
- Treating infections or inflammation
- Removing or treating kidney stones
For advanced kidney disease, dialysis or kidney transplantation may be needed. Early treatment can often help slow the progression of kidney damage and improve quality of life.
