When the patient lowers his head to work with the symptoms of dizziness, it is necessary to consider that it may be caused by postural hypotension, which occurs when the cerebral blood supply is insufficient and the patient will show the symptoms of dizziness. There is also cervical spondylosis, vertebral artery type of cervical spondylosis, when the patient lowers the head, the vertebral artery will be compressed, will also lead to the patient to appear dizziness symptoms. There is also low head, may lead to spasm of the vertebral artery, the patient will appear dizziness, and the degree of dizziness will be heavier, may be accompanied by nausea, vomiting, panic, cold sweat symptoms. The symptom of dizziness when the patient works to lower the head is also not excluded from being caused by benign paroxysmal positional vertigo, also known as otolithiasis. Because the otolith particles in the equilibrium receptors are dislodged, of course, when the head is lowered, with the change of head circumference, the otolith will stimulate the cell membrane of the semicircular canals, resulting in episodic dizziness with the symptom of rotating vision, and it is recommended that the patient consults the hospital to do the positional test for clarification.
