Getting up in the morning and standing unsteadily with a feeling of dizziness may be due to insufficient cerebral blood supply, postural hypotension, cerebrovascular disease, cervical spondylosis and so on. 1. Postural hypotension: when you get up in the morning and change from a lying position to a standing position, the sudden change in position may cause blood to fail to travel upward to the head, resulting in postural hypotension, which leads to temporary insufficient cerebral blood supply and oxygenation, and thus vertigo. 2. Cerebrovascular diseases: Due to cerebrovascular diseases such as cerebral arteriosclerosis and embolism, a change in body position may lead to transient ischemic attack, causing transient ischemia and insufficient blood and oxygen supply to the brain, resulting in vertigo. 3. Cervical spondylosis: patients with cervical spondylosis may suffer from vertebral artery compression due to poor sleeping posture and change of head position when getting up, which may result in insufficient blood supply to the brain and lead to vertigo. Sometimes there will be numbness of the hands, neck pain and other symptoms. 4. People who are obese and snore at night may not breathe well at night due to obstructive sleep apnea, resulting in insufficient oxygen supply to the brain and dizziness in the morning, unsteadiness, headache and other symptoms. Dizziness in the morning, need to pay attention to the situation, timely consultation to clarify the cause, targeted treatment.
