Mrs. Sita is 54 year old housewife . She developed diabetes 4 years ago and was constantly feeling tired in-spite of following diet, physical activity and oral hypoglycemic medication. 

Most of the regular check ups done revealed normal study. This tiredness sometimes better and sometimes worst now part of her life. Recently, tiredness increased to an extent which impaired her activities of daily living. That's when vitamin D levels was done which showed 11.78 ng/ml indicating she was deficient for vitamin D which was reason for her unexplained tiredness. 

She followed the report with doctor who gave her oral supplements  and she felt much better. 

India is a tropical country with an abundant sunlight . Despite which many deficient cases of vitamin D are seen.

Vitamin D is synthesised by our skin from cholesterol  in our body upon exposure to the sunlight through a chemical reaction.
