Good morning Doctor! I ve got up this morning and sat for a minute. Later went to washroom for brush teeth and took brush and paste. That time my head was reeling and I was unconsciousness and after a while, I was sitting on the washroom floor. I don t know what happened and came out from washroom and drank some water. Later understood that, I didn t do brush and I fell down and my brush has fallen aside. By reading these articles, I understood that, the blood is not reaching to brain properly and got unconsciousness. Is this true. If so, what could be the remedy. Please advice. My medical history: I have this dizziness when I sat on my toes (or on my foot) for a while and got up immediately. when I consulted a physician and asked this question long ago (around 4 years back). He said that, you are 40 years and these are common problems at that age. Later I have consulted another doctor and asked the same question. he said that it could be because of my D vitamin deficiency. That time I had little D vitamin deficiency. I had high Cholesterol with High Triglycerides, High LDL and Low HDL. But now its controlled and recently in March I had annual checkup and everything is normal. Regards,
