Are you concerned that your kidneys might be failing? Here’s a concise rundown of what you need to know about kidney failure and the symptoms to watch for, as they can signal serious trouble if ignored.
Kidneys are small but mighty organs, working tirelessly to filter about half a cup of blood every minute, removing waste and excess water to create urine, according to the National Institute of Diabetes and Digestive and Kidney Diseases. Beyond that, they play a critical role in maintaining the body’s balance—regulating blood pressure, supporting red blood cell production, and keeping bones strong. When kidneys falter, this harmony collapses, potentially triggering issues like hypertension, anemia, or bone weakness.
Kidney failure specifically refers to when these organs can no longer perform their essential tasks adequately. It can stem from various causes—think diabetes, obesity, smoking, poor diet, or even kidney stones—but today, we’re zeroing in on failure itself. The warning signs are often subtle at first, yet they become hard to miss as the condition worsens.
Key symptoms include swelling in your legs, feet, or ankles due to fluid buildup, persistent fatigue, headaches, and unexplained itching. You might also notice stomach upset, a metallic or altered taste in food, or a loss of appetite. Physical clues like muscle cramps, pain, numbness, or stiffness can crop up too. The most telling red flag? A sharp drop in urination—either producing less than usual or stopping altogether.
If you spot three or more of these symptoms, don’t wait—consult a doctor. Even if your only sign is reduced urination, it’s urgent enough to warrant a visit to your primary care provider, who can refer you to a specialist for tests. Early detection and treatment are key to slowing the disease’s progression and protecting your health.
