Hi Doctor, my father is 58 years old. His lab report shows severe vitamin D deficiency, with a reading of 9 ng per ml. He is not able to sleep, feels depressed, has negative thoughts, and feels very low. Please confirm if his depression and low mood could be caused by vitamin D deficiency?

Yes, low Vitamin D can lead to fatigue, mood swings, and sleep disturbances. With levels this low, supplementation and regular sunlight exposure are needed. Emotional symptoms usually improve gradually with correction.

I recently had a blood test, which showed that my vitamin D level is 3.2, indicating a deficiency. Which type of doctor should I consult, and what precautions should I take immediately? I am also attaching my blood test report.

Answered by Apollo Doctors

My blood test report of 8 April shows 25 OH Vitamin D 17.3 ng/ml and serum calcium 10.3 mg/dl. It is usually said that vitamin D deficiency causes low calcium, but my calcium is almost high. Could there be another problem? I recently passed a kidney stone. Is it related? Is having sun exposure for 15 minutes every morning enough for vitamin D?

I am experiencing frequent mood fluctuations and get anxious easily. Recently, I have gained a lot of weight despite no changes in my food habits, and my thyroid test is normal. I often feel very sad, have no enthusiasm for anything, and feel like giving up easily. My sleeping patterns have changed drastically, I either sleep too much or very little. What could be causing this, and what should I do?
