[|Human|] When I stand up my vision goes away and I become very dizzy and usually have to find something to hold on to until it comes back which has been anywhere from 10-30 seconds each time it happens. It leaves me feeling disoriented and it happens almos every time I stand up or sit up from laying down. I m only 17 years old. What is happening to me and how can I fix it?
[|AI|]  DearWelcome to ChatDoctorWe understand your concerns went through your problem description and I suggest you not to worry much about it.Instead, start doing physical activities and exercise. You are just 17, and I hope you are healthy. This vision problem is out of dizziness and dizziness is due to rush of blood to head. And this shows lack of exercise. Atleast 20 to 25 sit-ups daily and other physical exercises for one hour should help you. Don't worry. Hope this clears your doubts. Available for further clarifications. Good luck.
