Yawning all the time is cerebral hypoxia

Yawning all the time, may be a manifestation of cerebral hypoxia, can be seen in a variety of reasons, such as insufficient blood supply to the brain can be caused, can occur in a variety of diseases, such as severe hypotension, severe hypovolemia can be shown. If there is a heart disease, such as severe arrhythmia, severe coronary heart disease, may cause heart pump volume reduction, resulting in brain hypoperfusion may cause cerebral insufficiency. If the patient has vascular stenosis, some stress cases, can also show. If there is cerebral atherosclerosis, such as middle-aged and elderly patients with a history of hyperlipidemia, diabetes and hypertension, increased blood viscosity, poor vascular elasticity, lumen stenosis, tube wall stiffness, some stress cases may also cause cerebral insufficiency.
