The causes of hypocalcemia can range from hormonal imbalances to an improper diet. Without adequate calcium, blood has difficulty coagulating, the heart may skip beats or stop beating altogether, muscles may have difficulty contracting, nerves may have difficulty functioning, and bones may become brittle. Hypocalcemia, a condition characterized by abnormally low levels of calcium, can have an adverse effect on a number of different body systems including circulation, muscles, nerves, and bone. When the body cannot maintain this level, a person will experience hypo- or hypercalcemia. The normal level of calcium in the blood is about 10 mg/dL. Calcium ions are needed not only for bone mineralization but for tooth health, regulation of the heart rate and strength of contraction, blood coagulation, contraction of smooth and skeletal muscle cells, and regulation of nerve impulse conduction. Explain the process of calcium homeostasisĬalcium is not only the most abundant mineral in bone, it is also the most abundant mineral in the human body.Describe the effect of too much or too little calcium on the body.By the end of this section, you will be able to:
