3. Frequent use of anti-inflammatory drugs
Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, naproxen, and diclofenac are widely used for pain and inflammation. However, chronic or excessive use of these medications can cause kidney damage by reducing blood flow to the kidneys and inducing inflammation in kidney tissues.
This effect is especially concerning for people over 50, who may already have reduced kidney reserve. NSAID-induced kidney injury can lead to acute kidney failure or contribute to the progression of chronic kidney disease.
If you rely on NSAIDs regularly, discuss safer alternatives and appropriate dosages with your healthcare provider. Avoid self-medicating for prolonged periods without medical supervision.
4. Diet rich in ultra-processed foods
Ultra-processed foods—including fast food, packaged snacks, processed meats, and sugary beverages—contain high levels of additives, preservatives, and hidden sodium. These substances increase the kidneys’ workload and promote inflammation that impairs their filtering ability.
Additionally, these foods often lack essential nutrients and fiber, contributing to obesity, diabetes, and hypertension, all established risk factors for kidney disease.
Reducing ultra-processed food consumption by focusing on whole foods like fruits, vegetables, whole grains, and lean proteins supports kidney health and overall metabolism.
5. Excess sugar
High sugar intake, especially added sugars and fructose, contributes to elevated blood glucose levels and insulin resistance. Poorly controlled blood sugar is a leading cause of diabetic nephropathy, a form of kidney damage that arises from diabetes mellitus.
Chronic hyperglycemia damages the glomeruli, the kidney’s filtration units, leading to proteinuria (protein in the urine) and progressive kidney function loss.
Limiting sugar consumption, particularly from sweetened beverages, desserts, and processed foods, is critical for preventing diabetes-related kidney complications.
