Your Kidneys: The Unsung Heroes of Your Body

by Vinayak

Your kidneys are two bean-shaped organs located in your lower back. They play an important role in your body by filtering waste products from the blood, regulating blood pressure, and producing hormones that control red blood cell production and help keep your bones strong. This article discusses the functions of the kidney, how to protect it, and the stages of kidney disease, as well as prprovidesome statistics on kidney disease and recommends a kidney-friendly diet.

Functions of the Kidney

Your kidneys are responsible for filtering waste products and excess fluid fluids from your blood. They also help regulate electrolyte levels in your body, such as sodium and potassium. In addition, the kidneys produce hormones that regulate blood pressure, control red blood cell production, and help maintain healthy bones.

Kidney disease affects millions of people worldwide. In the United States, an estimated 37 million people have kidney disease, and more than 700,000 suffer from kidney failure. Diabetes and hypertension are the most common causes of kidney disease. Early detection and treatment of kidney disease can help slow or prevent the progression of the disease.

How to protect your kidneys

There are several ways to protect your kidneys and keep them healthy. These include:

  • Drinking plenty of water: drinking plenty of water can help flush toxins from your kidneys.
  • Eating a balanced diet: A diet rich in fruits, vegetables and whole grains can help protect your kidneys.
  • Maintain a healthy weight: Being overweight can increase your risk for kidney disease.
  • Exercise regularly: Regular exercise can help reduce your risk of kidney disease.
  • Avoid smoking: Smoking can damage the kidneys and increase the risk of kidney disease.

Do’s and don’ts to avoid kidney disease

To avoid kidney disease, it is important to follow these rules:


  • Control your blood pressure: High blood pressure can damage your kidneys over time.
  • Control your blood sugar: High blood sugar can also damage your kidneys.
  • Take medicines as directed: some medicines can damage your kidneys if taken improperly or in high doses.
  • Get regular kidney function tests: Regular kidney function tests can help detect early signs of kidney disease.

Do not:


  • Excessive use of pain medications: Excessive use of pain medications such as ibuprofen or aspirin can damage your kidneys.
  • Smoking: Smoking can damage your kidneys and increase your risk for kidney disease.
  • Consuming too much salt: Consuming too much salt can increase blood pressure, which can damage the kidneys over time.

Stages of kidney disease

There are five stages of kidney disease, ranging from mild damage (stage 1) to kidney failure (stage 5). In the early stages of kidney disease, there may be no symptoms. Therefore, it is important to test kidney function regularly to detect signs of damage. Treatment for kidney disease depends on the stage and severity of the disease.

Kidney function tests

Kidney function tests measure how well your kidneys are working. These tests include blood tests, urine tests, and imaging tests. Regular kidney function tests are important to detect signs of kidney damage early when treatment is most effective.

Blood urea nitrogen (BUN):

Blood urea nitrogen (BUN) is a test that measures the amount of nitrogen in your blood that comes from the waste product urea. Urea is produced when your body breaks down protein. If your kidneys are not working properly, they may not be able to remove urea from your blood, resulting in high BUN levels.


Creatinine is a waste product produced by your muscles and removed from your blood by your kidneys. A creatinine test measures the level of creatinine in your blood. High creatinine levels may indicate that your kidneys are not working properly.

Glomerular Filtration Rate (GFR):

The glomerular filtration rate (GFR) is a measure of how well your kidneys philtre waste from your blood. This test is usually calculated based on your creatinine level, age, gender and race. A GFR below 60 may indicate kidney disease.

Urine albumin creatinine ratio (ACR):

The urine albumin-to-creatinine ratio (ACR) measures the amount of protein albumin in your urine compared to the amount of creatinine. Albumin is a type of protein that is not normally found in urine. If your kidneys are not working properly, albumin can get into your urine, indicating kidney disease.

The importance of renal function tests:

Kidney function tests are important to detect kidney disease at an early stage before symptoms appear. Early detection allows timely intervention to prevent further damage to your kidneys. Kidney function tests can also help monitor the progression of kidney disease and the effectiveness of treatment.

Interpreting the results of kidney function tests:

Kidney function test results can vary depending on your age, gender and general health. Your doctor will interpret your test results and explain what they mean for your kidney health. If your test results indicate kidney disease, your doctor may recommend additional tests or refer you to a nephrologist, a specialist in kidney disease.

Kidney-friendly diet

A kidney-friendly diet includes foods that are low in sodium, phosphorus and potassium. It also includes foods that are rich in fibre and protein. The following foods should be included in a kidney-friendly diet

  • Fruits and vegetables
  • Whole grains
  • Lean protein, e.g. chicken or fish
  • Low-fat dairy products
  • Healthy fats, such as olive oil or avocado


Your kidneys are vital organs that perform important functions to keep your body healthy. To protect your kidneys and prevent kidney disease, you need to adopt a healthy lifestyle, go for regular check-ups and follow a kidney-friendly diet if necessary. By taking care of your kidneys, you can lower your risk of developing kidney disease and enjoy better overall health.
