Vitamin D deficiency fast becoming a global and national health concern: Study
A study conducted by the Diabetes Foundation of India revealed that around 80 per cent of the Indian population has Vitamin D levels less than normal. However, the bigger concern is that the population at large is not even aware of Vitamin D deficiency and its consequences.
The study further revealed that we might live in a country full of sunshine but Indians are still deprived of the sunshine vitamin, Vitamin D – which is called a pro-hormone that influences the expression of more than 200 genes within the human body. According to the study nearly every tissue in the human body has receptors of Vitamin D, be it brain, heart, skin, kidney, pancreas etc. Any deficiency of Vitamin D in the human body is bound to affect normal functioning of all organs having Vitamin D receptors.
Commenting on the same, Dr Banshi Saboo, Founder of Diabetes Foundation of India, said, “Earlier Vitamin D was thought to be responsible for maintaining calcium homeostasis to prevent osteoporosis and maintain bone health. But, in the past decade research has established the strong association of Vitamin D deficiency in diabetes, immunity, asthma, TB, high blood pressure, neuro-muscular function, etc.
Dr Saboo further added, “Low level of Vitamin D is associated with higher incidence of Type 2 diabetes and correcting Vitamin D deficiency improves insulin sensitivity and helps in better management of hyperglycaemia. Also Vitamin D deficiency has been associated with high incidence of Type 1 diabetes.”
As the mother is the sole source of vitamin D substrate for her developing foetus, vitamin D status is very important during pregnancy. Maternal deficiency of vitamin D is linked with abnormal foetal growth and gestational diabetes.
Sunscreen lotions, staying indoors, clothing habits, pollution and minimal exposure to direct sun light (during the period of 10 am to 3 pm) are the major reasons of such widespread deficiency in the Indian population.
Endocrinologist from Mumbai, Dr Manoj Chadha said that Vitamin D deficiency has no defined signs or symptoms. “People who complain of back pains, unexplained muscle pains, general fatigue are the most likely to be Vitamin D deficient. Vitamin D deficiency can be easily corrected by Vitamin D supplementation or some lifestyle changes. In a Vitamin D deficient person, oral 60,000 I.U per week for 8 weeks followed by maintenance dose of 60,000 I.U per month is a reasonably safe method to correct the deficiency”, he added.
Although there are few major studies carried out in India to determine the optimum (sufficient) levels of serum Vitamin D 25(OH) D to be maintained to prevent chronic ailments, globally there is a consensus that Vitamin D deficiency is defined as serum 25(OH) D levels less than 20 ng/ml and insufficiency as serum 25(OH) D less than 30 ng/ml. Whereas serum 25(OH) D levels above 30 ng/ml is found to be sufficient.
Given the fact that Vitamin D receptors are present in various organs and tissues of the human body, maintaining Vitamin D levels in blood above 30 ng/ml may ensure normal functioning of the body organs and protect many from the suffering from chronic ailments.
