Vitamin D deficiency is increasingly recognized as a common health concern in the UAE, despite abundant sunlight. Limited sun exposure due to indoor lifestyles, sunscreen use, cultural clothing practices, and dietary insufficiency contribute to widespread deficiency. Vitamin D plays a vital role in bone health, immune function, muscle strength, and overall well-being.

Patients with vitamin D deficiency may experience fatigue, muscle aches, bone pain, frequent infections, or mood changes. In children, deficiency can affect bone development, while in adults it may contribute to osteoporosis or increased fracture risk.

Primary care physicians identify deficiency through blood testing measuring serum 25-hydroxyvitamin D levels. Many cases are detected during routine health screenings.

Management includes vitamin D supplementation tailored to deficiency severity. Oral supplementation is commonly prescribed in daily, weekly, or monthly regimens. Severe deficiency may require higher initial doses under medical supervision.

Dietary sources such as fortified dairy products, fatty fish, and eggs are encouraged. Safe sun exposure for short durations may support natural synthesis, though supplementation remains the most reliable correction method.

Vitamin D plays a role in immune resilience, making deficiency correction particularly relevant in regions with frequent respiratory infections. Follow-up testing ensures normalization of levels.

In high-risk groups such as elderly individuals, pregnant women, and individuals with obesity, regular monitoring is advised.

Vitamin D deficiency is preventable and treatable. Early detection and structured supplementation improve musculoskeletal health and overall vitality.
