Sometimes when I stand up or even sit up, i get really dizzy, my head starts to pound, and my vision blacks out. I thought it could be from getting up too fast, but it happens even when I am moving slowly. Why does this happen? Is it serious? I am 16 and 130 pounds.
Hi, Thank you for posting your query. I have noted your symptoms. Based on the description, we need to exclude postural hypotension- a Chat Doctor. This can be confirmed by checking blood pressure in lying down and in standing position. We also need to exclude anemia- a deficiency in hemoglobin. I hope my answer helps. Please get back if you have any follow-up queries or if you require any additional information. Wishing you good health,
