Why do i feel lightheaded after i bend over?

Try bending slowly: If you bend very fast you might be draining the blood from your brain, but you should check your BP and your h ;h.

Dizziness: Can occur when you stand up after bending over. This is due to a temporary change in your blood pressure, which can drop quickly, especially if your sick or dehydrated. Younger people like yourself usually recover quickly from this, but older people can have severe symptoms from this. If it persists, then see your doctor to have this evaluated further.
