What Are the Effects of Diabetes on Kidney Health?

How Does Diabetes Affect the Kidneys?

The kidneys contain millions of tiny blood-filtering structures called nephrons. Their job is to remove waste and excess fluid from the blood. When blood glucose remains high over time, it can damage the blood vessels and filtering structures inside the kidneys. High blood pressure, which commonly occurs alongside diabetes, can place additional stress on the kidneys. Over time, this damage can contribute to diabetic kidney disease, also called diabetic nephropathy. Kidney damage can reduce the kidneys' ability to filter waste properly. It can also cause proteins such as albumin to leak into the urine. Albumin in the urine, known as albuminuria, can be an early sign of kidney damage.

What Are the Effects of Diabetes on Kidney Health?

Diabetes may affect kidney health in several ways:

1. Protein May Leak Into the Urine

Healthy kidneys generally prevent significant amounts of albumin from passing into urine. When kidney filters become damaged, albumin may begin to appear in urine. A urine albumin-to-creatinine ratio (UACR) is commonly used to detect and monitor this problem.

2. Kidney Filtration May Decline

Doctors use estimated glomerular filtration rate (eGFR) to assess how well the kidneys are filtering blood. Tracking eGFR over time can help healthcare professionals identify changes in kidney function and monitor CKD.

3. Chronic Kidney Disease May Progress

Diabetic kidney disease can develop slowly. Without appropriate management, CKD can become more advanced and may eventually lead to kidney failure. However, early detection and appropriate medical management can help slow progression.

4. Heart and Blood Vessel Risks Can Increase

Kidney disease is closely connected with cardiovascular health. CKD can contribute to complications such as cardiovascular disease, while diabetes and high blood pressure can increase the risk of kidney damage.

What Are the Warning Signs of Diabetic Kidney Disease?

One challenge with diabetic kidney disease is that early stages may have few or no obvious symptoms. This is why regular testing is important for people with diabetes. As kidney disease becomes more advanced, symptoms may include swelling, changes in urination, tiredness, nausea, or other health changes. These symptoms can have many possible causes, so anyone experiencing them should discuss them with a healthcare professional rather than assuming they are caused by diabetes.

How Is Diabetes-Related Kidney Disease Diagnosed?

Kidney health is generally evaluated using blood and urine testing. A blood test can measure creatinine and help calculate eGFR, while a urine test can measure albumin and creatinine. NIDDK recommends annual assessment of urine albumin and eGFR for people with type 2 diabetes and for people who have had type 1 diabetes for five years or more, with more frequent monitoring when clinically appropriate.

How Can You Protect Your Kidneys If You Have Diabetes?

Managing diabetes is an important part of protecting kidney health. Depending on your individual condition, your healthcare professional may recommend managing blood glucose, blood pressure, cholesterol, nutrition, physical activity, weight, and medications.

NIDDK notes that blood pressure control, appropriate diabetes management, prescribed medications, nutrition counseling, physical activity, maintaining a healthy weight, adequate sleep, and avoiding smoking can all be important components of CKD management. If you already have kidney disease, do not stop or change prescribed medicines without speaking with your healthcare professional.

Can Ayurveda Support Kidney Health?

At Karma Ayurveda, we recognize that people with diabetes and kidney concerns may be interested in holistic approaches. Ayurvedic practices may be considered as a complementary wellness approach, such as supporting healthy lifestyle habits and nutrition.

However, diabetic kidney disease requires appropriate medical evaluation and monitoring. Ayurvedic products or supplements should not be used as a replacement for prescribed diabetes or kidney treatment. Some supplements can interact with medications or may be unsuitable for people with reduced kidney function. Discuss any Ayurvedic herbs or supplements with your U.S. healthcare professional, particularly if you have CKD, take prescription medicines, or are pregnant. Karma Ayurveda can provide educational information about Ayurvedic approaches to kidney wellness, while medical diagnosis and treatment decisions should remain under the guidance of qualified healthcare professionals.

FAQs

1. Can diabetes cause kidney disease?

Yes. Diabetes is a major cause of chronic kidney disease. Persistently high blood glucose can damage kidney blood vessels and filtering structures over time.

2. What is the first sign of diabetic kidney disease?

Albumin in the urine can be an early sign of kidney damage and may occur before noticeable symptoms. A urine albumin-to-creatinine ratio can help detect albuminuria.

3. How often should people with diabetes have kidney tests?

NIDDK recommends yearly assessment of eGFR and urine albumin for people with type 2 diabetes and for those with type 1 diabetes lasting five years or more. Your healthcare professional may recommend testing more often depending on your health.

4. Can diabetic kidney disease be prevented or slowed?

Managing blood glucose and blood pressure, following an appropriate treatment plan, maintaining healthy lifestyle habits, and monitoring kidney function can help prevent or slow kidney damage.

5. Can Ayurveda treat diabetic kidney disease?

Ayurveda should not be presented as a replacement for evidence-based medical treatment for diabetic kidney disease. If you are interested in Ayurvedic care, discuss it with your healthcare team and choose a qualified practitioner who understands your kidney function, diabetes, and medications.
