[|Human|] Thank you....I often get lightheaded after bending over. I am quite tall (6 3 ) and while I am 66 years old this has been a lifelong issue since I was a young adult. It generally goes away in a minute or so. I am in good health and am not overweight nor do I have any chronic health issues. The only medication I take is 10mg of Lipitor at night. Thank you, Bourke Corcoran YYYY@YYYY
[|AI|]  Hi, Thanks for writing in. The feeling of lightheaded after bending down is explainable. The brain gets its blood supply from the heart through the carotid and vertebral arteries. The carotid arteries transmit the blood along the front and sides of the neck region and the vertebral arteries run through the spine. When bending, it is possible that there is decreased blood flow to the brain momentarily and since you are experiencing it from when you were a young adult, it looks likely due to positional changes of the cervical spine and mild pressure on the vertebral arteries when you bend down. Lipitor (atorvastatin) is used to treat high cholesterol and will help in clogging your arteries should there be any blocks due to aging. This will enable good flow of blood to your brain. Please do not worry.
