👉 Phosphatemia is a condition in which there is an accumulation of calcium ions (Ca2+) in the blood, leading to symptoms such as muscle weakness, cramping, and pain. This can occur when the body's calcium stores are depleted or when calcium levels are too high due to certain medical conditions. It is often associated with kidney disease, where calcium deposits build up in the kidneys, causing them to swell and compress the ureters (the tubes that carry urine from the bladder).
