Hello,
Welcome to Healthcare Magic,

In our todays Hurry-burry lifestyle & working in airconditioned offices, vit -D deficiency is becoming a major health concern.
Vit-D is synthesized in our body just underneath our skin through the sun light , so we call it as SUNSHINE VITAMIN.

Vit -D is essential for following metabolisms:-

1.Vit-D helps in minerilization of bone by increasing the absorption of calcium through the intestines and there by strengthens your bone.
2.Recent evidences say vit-D is very essential in preventing the cardiovascular diseases.So every physician prescribing vit-D along with general prescription
3. Vit-D increases the sensitivity of insulin on the peripheral tissues there by decreases the chances of eary onset of Diabetes.


In case of deficiency of vit-D :-

1.Your bones becomes weak gradually, and there is chance of fractures
2.There is increased risk of cardiovascular diseases

All the above consequences can be reversible if you start the vit -D ASAP.

coming to precautions :-
1.Expose to morning and evening sun light(Like sun bathe in a nice beach)
2.Vit-D is generally present in animal based, including fish and fish oils, egg yolks, cheese, fortified milk, and beef liver.

Your next question about root cause :-

Most of the times the defeciency is due to improper intake of vit -d containing foods and lack of exposure to sunshine. so you dont require any further tests.

Discuss with your family physician and start Vit-D ASAP.

Detailed Answer:
Hello,
Thanks for contacting me on Healthcare Magic,

Apart from the lack of sun-exposure there are two main causes of Vit -d deficiency,

1. Dietary abscence of Vit -D
2. Malabsorption of Vit -D through gut.

Other causes include :-

1.patients who are on anti-epileptic drugs like phenytoin,phenobarbitone
2.Diabetic patients
3.Patients with improper kidney function like CKD (chronic kidney disease) due to either long standing diabetes or hypertension
4.patients who are on dialysis

So , my final conclusion is that the possible reason for low vit d levels in your case is due to Lack of sun exposure and Dietary deficiency of vit D. Because I dont find other medical illness in you.

Try this :-
If you are a non-veg person eat good amount fish, beef/lamb liver ,egg, milk.
