Your kidneys perform important functions every day, including filtering waste from the blood and helping maintain the body's fluid and mineral balance. Kidney problems may develop gradually, and some conditions may not cause obvious symptoms in the early stages. Understanding kidney health and managing important risk factors can support long-term wellbeing.
What do the kidneys do?
The kidneys are two organs located in the lower back area of the body. Their main role is to filter the blood and remove waste and excess fluid through urine. They also help maintain the balance of fluids and minerals in the body.
The kidneys are also involved in functions related to blood pressure, red blood cell production and maintaining healthy bones. This makes kidney health an important part of overall health.
Common factors that can affect kidney health
Several health conditions and lifestyle factors can increase the risk of kidney problems. Managing these factors can be an important part of protecting kidney function.
- Diabetes or persistently high blood sugar
- High blood pressure
- Excess body weight
- Smoking and tobacco use
- Family history of kidney disease
- Previous kidney problems or certain medical conditions
- Long-term or inappropriate use of certain medicines
Warning signs that should not be ignored
Some kidney conditions may not cause noticeable symptoms early on. However, certain changes can indicate that medical evaluation is needed.
- Persistent changes in urination
- Blood in the urine
- Swelling around the ankles, feet or face

Simple habits that support kidney health
Protecting kidney health involves taking care of your overall health. Healthy lifestyle habits and regular medical checkups can help manage factors that may affect kidney function.
- Manage blood pressure: Keep blood pressure under control through healthy habits and medicines when prescribed.
- Keep blood sugar under control: Good diabetes management can help reduce the risk of kidney damage.
- Stay physically active: Regular suitable physical activity supports overall health and healthy body weight.

Why regular kidney health checks matter
People with diabetes, high blood pressure, a family history of kidney disease or other risk factors may benefit from regular kidney health assessments. Your doctor can recommend appropriate blood or urine tests based on your individual health needs.
Identifying kidney problems earlier can provide an opportunity to address underlying causes and manage risk factors before kidney function is significantly affected.
Stay appropriately hydrated
Adequate fluid intake is part of maintaining normal body function. However, fluid requirements are not the same for everyone. People with certain kidney, heart or other medical conditions may receive specific fluid recommendations from their doctor.
