Suddenly heavy head and light feet, consider central and peripheral causes: First, central causes, such as acute cerebrovascular disease, cerebral infarction, cerebral hemorrhage, patients can suddenly have symptoms of heavy head and light feet, dizziness, and may also be accompanied by slurred speech, crooked mouth, limb weakness and other symptoms. In this case, the patient should go to the hospital for a CT or MRI scan of the head to rule out any central causes and to provide timely symptomatic treatment. Second, peripheral causes, such as vestibular dysfunction, benign positional vertigo, cervical spondylosis, etc., can also cause sudden heavy head and light feet, accompanied by violent vertigo attacks. However, the onset of symptoms in these patients is mostly related to the change of body position, without other accompanying neurological symptoms. Symptomatic treatment can be given for these episodes of light-headedness, and oral anti-vertigo medication can be given.
