Vitamin D deficiency for expat residents

Living in a sunny country does not automatically mean that vitamin D levels are adequate. Work, commuting, heat avoidance, clothing, sunscreen use, darker skin pigmentation and time spent indoors can all affect how much ultraviolet light reaches the skin. Food traditions and changes after moving country can also alter vitamin D intake.

Symptoms such as fatigue, generalised weakness, bone discomfort or low mood can have many causes, including disrupted sleep, stress, infection or another medical condition. Tell the clinician where you previously lived, how long you have been in the UAE, and whether you have test results or treatment records from another country.

Make a list of medicines, supplements, dietary restrictions and relevant diagnoses. Bring previous laboratory reports if available, including the date and the units used by the laboratory. Do not assume that a supplement bought abroad has the same strength or ingredients as a local product. A clinician can decide whether a blood test is needed and recommend a plan that fits your health, routine and pregnancy status if relevant.

Arrange a routine assessment for persistent tiredness, muscle weakness, bone or joint pain, or a history of deficiency without follow-up. Seek urgent help for sudden severe weakness, confusion, a serious fall, or intense pain after a minor injury. These symptoms need prompt assessment rather than self-treatment with supplements.

Could my daily routine or diet contribute to low vitamin D? Are my overseas test results comparable with local testing? Should I continue, change or stop my current supplement? When should my level or symptoms be reviewed?
