I am feeling sudden dizziness with light headness sometimes during evening. Also I feel spin head if I suddenly stand up after siting quite a time. These happens with little vision disturbance and lack of concentration. Also I feel heavy and have balance problem while walking at the same time. All started one month back after recovering from typhoid. First I thought this is kind of side effects from antibiotics At time of treatment it used to happen all the time, but now it happens sometimes in the evening not everyday two three days a week. I have checked all blood count, anemia profile, kidney and liver function, vit D, urine routine etc Everything is normal except vitamin D. Vit D level is very low around 7 ng/ml (30-70) is normal. My question is can VIT D deficiency cause vertigo or dizziness and what medicine is to take to overcome this?
