Understanding Kidney Health
The kidneys are a pair of organs located in the lower back that play a vital role in maintaining overall health. They are responsible for filtering waste products, excess fluids, and toxins from the blood. And they help regulate blood pressure, electrolyte balance, and the production of red blood cells.
When the kidneys are not functioning properly, waste products and excess fluids can build up in the body. This leads to a range of health problems, such as high blood pressure, anemia, bone disease, and even kidney failure.
There are many factors that can affect kidney health, including genetics, age, lifestyle choices, and certain medical conditions. It’s important to maintain good kidney health by staying hydrated; eating a balanced diet; avoiding tobacco and excessive alcohol consumption; getting regular exercise; and managing any medical conditions that may affect kidney function.
When Should I Test My Kidneys?
Regular check-ups with a healthcare provider can also help detect any potential kidney problems early on. And which can improve the chances of successful treatment and prevent long-term kidney damage.
In general, adults over the age of 18 should have their kidney function tested at least once a year as part of their routine medical check-up. People with high blood pressure, diabetes, or a history of kidney disease, should have their kidney function monitored more frequently. This is because these health conditions can increase the risk of kidney problems.
If you experience any symptoms that may indicate kidney problems, such as swelling in the legs, feet, or face, changes in urination patterns, or fatigue, you should talk to your healthcare provider about getting your kidneys tested.
If you have a family history of kidney disease, your healthcare provider may recommend starting kidney function testing at an earlier age; such as in your 20s or 30s.
It’s important to note that early detection and treatment of kidney problems can help prevent or slow down the progression of kidney disease, so regular kidney function testing is essential for maintaining good kidney health.
What Blood Tests Help Check your kidney health?
Several blood tests can help assess kidney health and function.
These tests measure various substances in the blood that are processed by the kidneys, such as:
- Creatinine: This waste product is produced by muscles and excreted by the kidneys. Elevated levels of creatinine in the blood can indicate reduced kidney function.
- Blood urea nitrogen (BUN): This waste product is produced by the liver and excreted by the kidneys. Elevated levels of BUN in the blood can indicate reduced kidney function.
- Glomerular filtration rate (GFR): This is a measure of how well the kidneys are filtering the blood. It is calculated based on creatinine levels, age, sex, and other factors.
- Electrolyte levels: The kidneys help regulate electrolyte levels in the body, including potassium, sodium, and calcium. Abnormal levels of these electrolytes in the blood can indicate kidney problems.
Your healthcare provider may also recommend additional tests, such as a urinalysis or imaging studies to evaluate kidney health and function. It’s important to talk to your healthcare provider about your specific health needs and which tests may be appropriate for you.
