Eat greasy things feel dizzy causes include patients blood flow redistribution, insufficient blood supply to the brain, as follows: 1, patients blood flow redistribution: eat greasy things after the gastrointestinal system needs to be mobilized, the digestion and absorption of greasy food, this time the blood flow is easy to redistribute, focus priority to the gastrointestinal tract, the blood flow to the brain will be reduced, the brain is very sensitive tissue to ischemia, hypoxia The brain is very sensitive to ischemia and hypoxia of the tissues, sometimes produce dizziness symptoms, for the feeling of dizziness; 2, cerebral blood supply is insufficient, eat greasy things after the patient’s blood lipids will rise significantly, if the patient himself has hyperlipidemia or blood viscosity is too high, the circulation of blood will be slowed down. If the patient has cerebrovascular lesions, resulting in partial narrowing of blood vessels, there will be a lack of blood flow, reduced blood supply to the brain, causing dizziness, mainly caused by ischemia of the posterior circulation.
