Calcium deficiency in the elderly first manifests as pain in multiple bones and joints throughout the body, such as heel, knee, lumbar, and neck pain. Due to the decrease in blood calcium, spasmodic contraction of muscles may also occur, causing leg cramps. In addition, calcium deficiency can cause changes in the vertebral space, leading to a hunchback and a decrease in height. A few patients may also show symptoms such as itchy skin, loss of appetite, constipation, and loose teeth loss. Prolonged calcium deficiency can lead to significant osteoporosis and predisposition to compression fractures.
