Calcium deficiency occurs when the body does not get enough calcium, an essential mineral for strong bones and teeth. This condition can lead to various health issues, including weakened bones, which may increase the risk of fractures and conditions like osteoporosis. Symptoms can include muscle cramps, numbness, and fatigue, making it important to maintain adequate calcium levels through diet or supplements. To prevent calcium deficiency, it's crucial to consume foods rich in calcium, such as dairy products, leafy greens, and fortified foods. Regular check-ups with a healthcare provider can help monitor calcium levels and ensure that individuals are meeting their nutritional needs for overall health.
