Hypercalcemia describes an abnormally high amount of calcium in the blood. Calcium is an important mineral for the human body. It is important for the normal functioning of the muscles, cells, nerves, and organs. Calcium also helps the bones stay strong and is vital to blood clotting. However, too much calcium in the blood can weaken the bones. It can also lead to problems with the functionality of the brain and heart. Extremely high calcium levels in the blood can even be life-threatening.
Individuals with mild cases may not experience any symptoms. Others may get headaches, fatigue, nausea, constipation, vomiting, decreased appetite, abdominal pain, muscle twitches, muscle cramps, bone pain, increased thirst, frequent urination, and muscle weakness. Neurological symptoms include depression, irritability, and memory loss. Severe cases can lead to confusion, fainting, and heart palpitations.
