Recent smoking often dizziness is usually the result of three factors. First, smoke intoxication, because of the recent inhalation of excessive or large amounts of nicotine, tar components caused by gas poisoning, then you need to perform oxygen therapy treatment, that is, leave the surrounding nicotine or tar components too dense environment, feasible home oxygen therapy or to the hospital to perform shielded oxygen therapy. Second, recently smoked often feel dizzy, usually because of insufficient blood supply to the heart and brain. Often due to coronary atherosclerotic heart disease or cerebrovascular vertebral basilar artery blood supply is insufficient, and caused by the cardio-cerebral ischemia, and therefore will produce dizziness after smoking. Third, the brain cells lack of oxygen, because of long-term heavy smoking will lead to severe oxygenation of brain cells, will lead to a decrease in blood oxygen saturation, carbon dioxide partial pressure increased, and therefore will lead to dizziness symptoms.
