Every human body has two kidneys, which are primarily in charge of filtering the blood to remove wastes that contain nitrogen, such as urea, creatinine, acids, etc. and to produce urine. Numerous kidney diseases affect millions of people, most of whom are completely unaware of their existence. Due to the fact that most people do not notice any symptoms until the disease has progressed, kidney disease is frequently referred to as a “Silent Killer.” While people routinely have their blood pressure, sugar, and cholesterol levels checked, they neglect to have a simple blood creatinine test done to look for any hidden kidney issues. There are several warning signs of kidney disease, but they are frequently ignored or confused with other pathologies (because of their non-specific nature). As a result, one must be extremely vigilant and should have confirmatory tests performed as soon as any indication of a kidney disorder appears. One should consult a nephrologist to get any questions answered. However, it is advised to have regular kidney tests done if you have hypertension, diabetes, obesity, metabolic syndrome, or coronary artery disease, as well as if you have a family history of any of these conditions or kidney failure, or even if you’re older than 60. Here are some kidney disease early warning signs, though confirmatory tests are the only way to diagnose kidney disease with certainty: The appearance of swelling over the ankles, feet, or legs is one of the early symptoms: At these locations, one will begin to notice edema that pits when pressure is applied and is known as pitting edema. Your shin and ankles will swell as your kidney function starts to decline due to sodium retention.
