Renal failure occurs when the kidneys stop working properly. The kidneys are responsible for filtering waste from the blood, converting vitamin D into calcitriol, and maintaining a balance of calcium and phosphorus in the body. When the kidneys malfunction, phosphorous waste builds up in the blood and overrides calcium, leading to hypocalcemia.
Kidney failure occurs due to age, infection, high blood pressure, or genetic autoimmune disorders. It's important to get a checkup regularly to monitor your body for signs of potential kidney issues. Some of the symptoms of kidney failure include a lack of appetite, swelling in the feet and ankles, muscle cramps, nausea, and difficulty breathing. Although these symptoms individually can have other causes, taken collectively they are a sign of renal malfunction.
You can also improve the likelihood that your kidneys will remain healthy by eating a balanced diet, getting moderate exercise, and drinking plenty of water. Water decreases the work kidneys have to do and helps them last longer. Maintaining a healthy diet also keeps blood pressure low.
