Diabetes mellitus, commonly known as diabetes, is a chronic condition that exists in two primary forms: Type 1 and Type 2. If diabetes is left uncontrolled, it can severely affect various organs, including the kidneys. Uncontrolled diabetes is one of the leading causes of kidney failure worldwide. Research indicates that between 30% and 50% of people with diabetes (Lin et al., 2018) may develop kidney problems. The risk of kidney disease increases due to factors such as uncontrolled diabetes, chronic high blood pressure, a family history of kidney disease, and the prolonged duration of diabetes.
Kidney Complications Associated with Diabetes
The kidneys play a crucial role in filtering waste products from the body, which are then excreted through urine. When this filtering system is damaged—due to diabetes, high blood pressure, or other factors—important substances like protein may start leaking from the body through the urine. Although early detection and control of diabetes and blood pressure can help manage this condition, prolonged damage can lead to complete kidney failure. It is essential to adopt a healthy lifestyle, as well as manage diabetes and blood pressure under the guidance of a healthcare professional, to maintain kidney health.
How to Keep Your Kidneys Healthy
For diabetics, following specific guidelines is crucial for keeping the kidneys healthy. Controlling blood sugar and blood pressure within recommended limits is vital. Regular monitoring through blood tests, including urine tests to check for protein, can help assess kidney function and detect issues early. Dietary adjustments are also important, and following your doctor’s advice on diet, particularly regarding salt and protein intake, is key. It is advisable to limit animal protein and opt for plant-based sources when possible. Maintaining a healthy weight can reduce the strain on your kidneys, and avoiding smoking is essential since it can exacerbate kidney damage. Always consult with your doctor before taking any new medication to ensure it doesn’t harm your kidneys.
If the Kidneys are Damaged
If kidney damage progresses to the point of failure, a kidney transplant or dialysis may be required. Though beneficial yet both treatments are costly and carry some risks, making it crucial to take preventive measures to protect kidney health. For those with existing kidney disease, lifestyle changes are essential. Engaging in regular exercise, avoiding raw or fried salt, meeting protein needs primarily through vegetable sources, and refraining from foods high in saturated fat, such as beef fat, are important steps. Additionally, avoiding painkillers that can harm the kidneys and quitting smoking are necessary for maintaining kidney health. Along with these lifestyle changes, taking appropriate medication as prescribed by a doctor can be beneficial. Regular check-ups to monitor kidney function are essential to managing the condition effectively.
