Can Calcium Deficiency Cause Dizziness?

Calcium deficiency typically does not lead to dizziness. However, low calcium levels can cause symptoms such as leg cramps. In more severe cases, it may result in tetany — which includes symptoms like muscle spasms in the hands and feet — and even seizures. For middle-aged and elderly individuals, calcium deficiency can contribute to osteoporosis and may increase the risk of compression fractures. It is important to address calcium deficiency promptly through oral supplements such as calcium tablets or calcium carbonate D3, and in some cases, intravenous calcium gluconate may be necessary. Additionally, increasing sun exposure can help the body synthesize vitamin D, which plays a key role in calcium absorption.

Common Causes of Calcium Deficiency

There are several reasons why someone might develop a calcium deficiency. In adolescents, it can occur due to rapid growth, which increases the body's demand for calcium. In older adults, calcium loss tends to be more common, often due to age-related changes in bone metabolism. Another significant factor is the use of certain medications over a long period. For example, blood pressure medications such as calcium channel blockers — including amlodipine, sustained-release nifedipine, and controlled-release nifedipine — can contribute to reduced calcium levels with prolonged use.

How to Prevent and Manage Calcium Deficiency

To prevent and manage calcium deficiency effectively, it's important to maintain a balanced diet rich in calcium sources such as dairy products, leafy green vegetables, and fortified foods. Regular physical activity and adequate vitamin D intake — either through sunlight exposure, diet, or supplements — are also crucial for maintaining strong bones and optimal calcium levels. If you're taking medications that may affect calcium absorption, consult with your healthcare provider to monitor your levels and adjust your supplementation as needed.
