According to statistics, nearly 40% of people with diabetes are at risk of kidney damage. A diabetologist explains why regular screening is crucial.
Diabetes is a widespread health challenge affecting millions globally. While managing blood sugar is central, it’s important to recognize its impact on other organs—particularly the kidneys. Studies published in the Clinical Journal of the American Society of Nephrology indicate that almost 40% of individuals with diabetes may develop some form of kidney damage over time. This makes routine kidney screening essential for people living with diabetes, as proactive monitoring can safeguard long-term health.
What is the link between kidney disease and diabetes?
Diabetes, especially when poorly controlled, can lead to chronic kidney disease (CKD). High blood sugar can damage the small blood vessels in the kidneys, reducing their ability to filter waste efficiently. Over time, this damage may progress to CKD and, in severe cases, kidney failure, potentially requiring dialysis or transplantation, according to the National Kidney Foundation.
“Chronic kidney disease often develops without noticeable symptoms in its early stages. Many diabetic patients remain unaware of kidney damage until it becomes severe. Regular screenings, including urine and blood tests, can detect early signs and allow timely intervention,” says Dr. Jenish J. Vira, Diabetologist at Diabetes & O Clinic, in an interview with Health Shots.
How common is kidney disease among people with diabetes?
Research from the American Diabetes Association suggests that about 40% of individuals with diabetes are at risk of kidney disease. This statistic underscores the importance of regular kidney checkups. Early detection can significantly improve treatment outcomes, making consistent monitoring essential for those with diabetes.
How do sodium levels affect kidneys?
Beyond regular screenings, lifestyle choices play a major role in kidney health. One critical factor is daily salt intake. High sodium can raise blood pressure, a key risk factor for kidney disease. The World Health Organization recommends a daily salt intake of around 5 grams (about one teaspoon). Yet, many people consume far more, mainly through processed and restaurant foods, according to Frontiers in Nutrition.
Dr. Vira highlights hidden sources of sodium, including:
- Processed snacks
- Canned goods
- Bread and cheese
- Fast food
Excess sodium strains the kidneys, making it crucial for diabetic patients to monitor their intake, as advised by the National Institute of Diabetes and Digestive and Kidney Diseases.
How to adopt a low-sodium diet
Reducing salt intake can help protect kidney function. Here are practical tips:
- Read food labels: Choose lower-sodium packaged foods when possible.
- Cook at home: “Prepare meals from scratch using fresh ingredients to control salt,” suggests Dr. Vira.
- Limit processed foods: Opt for fresh fruits, vegetables, lean meats, and whole grains.
- Use herbs and spices: Enhance flavor without extra salt.
Lowering salt intake can help manage blood pressure, reduce stress on the kidneys, and slow disease progression, according to the Journal of the American College of Cardiology.
Lifestyle tips for managing chronic kidney disease
For those with both diabetes and CKD, focusing on three areas is key:
- Control blood sugar: Proper management reduces complications.
- Maintain a balanced diet: “A nutrient-rich diet supports overall health and kidney function,” advises Dr. Vira.
- Annual kidney checks: Regular tests can catch issues early and simplify management.
Steps to keep kidneys healthy with diabetes
Kidney disease can progress silently, making prevention critical. People with diabetes can take these measures:
- Schedule regular screenings to monitor kidney function.
- Learn how dietary choices impact kidney health.
- Make informed lifestyle decisions to reduce complications.
Routine checkups and a healthy diet help maintain strong kidneys and support overall well-being.
