Vitamin D deficiency may aggravate diabetes and high cholesterol

Vitamin D functions like a hormone, influencing insulin production, glucose metabolism, fat processing and liver health. Research links low vitamin D levels to a higher risk of type 2 diabetes, metabolic syndrome, non‑alcoholic fatty liver disease and cardiovascular problems such as elevated cholesterol and triglycerides.

Deficiency is common even during summer, as indoor work, extensive sunscreen use and urban air pollution limit UVB exposure. A distinctive symptom noted by clinicians is excessive sweating on the scalp and forehead, alongside fatigue, vague bone‑muscle aches and mood changes. Blood testing for 25‑OH vitamin D is the recommended diagnostic method. Supplementation, especially when combined with weight loss, balanced diet and regular exercise, can modestly improve blood glucose control and lipid markers.

Health professionals advise short daily sun exposure (10–15 minutes in the early morning) and, if needed, medical‑guided vitamin D supplementation to restore optimal levels and support metabolic health.
