Hello am 21 yrs. I have send this question earlier. I feel very tired and sluggish. Every time I get up frm bed or chair after a particular amount of time ,I get light headed and dizzy and I have to hold onto something for a few seconds in order to regain my strength. I am not anemic. Am healthy too. Recently I have a cold and that's all. I have no other problem. And another aspect is the weather is very hot so I thought that may be the reason but still even by sitting at home I feel tired and am unable to complete my piled up work too. The main problem is the dizzy spells I have every morning I wake. I would be great if the reply is without any further doubts since I can't reply again .thank you.
