Lying awake and getting up dizziness may be caused by postural hypotension, benign paroxysmal positional vertigo, and transient cerebral ischemia.
1. Postural hypotension: also known as upright hypotension, is a disease in which blood pressure drops when the body undergoes postural and positional changes, which in turn leads to dizziness, black haze and other symptoms. It often develops when there is a sudden change from a low position to a high position, such as from squatting or lying down to sitting up or standing up. Positional hypotension may also be associated with autonomic dysfunction.
2. Benign paroxysmal positional vertigo: also called otolithiasis, it is a common peripheral vestibular disease, which often manifests as transient vertigo when the head moves to a particular position, and this disease also has the symptom of lying awake and getting up dizziness, and may be accompanied by nystagmus, nausea, vomiting, and a feeling of lightness of the head and feet.
3. Transient cerebral ischemia: transient insufficient blood supply to the blood vessels in the brain, which may occur when the body position changes, and the phenomenon of lying awake and getting up dizzy may occur.
The symptoms of lying awake and getting up dizzy may also be caused by other diseases, such as stroke. If the symptoms persist without relief, please seek medical attention and ask your doctor to identify the cause to avoid delay.
