Why Do I Feel Dizzy and My Vision Is Blurry When Walking in the Morning? What Should I Do?
Upon waking up in the morning and walking, experiencing blurred vision and dizziness may be caused by orthostatic hypotension, benign paroxysmal positional vertigo (BPPV), or Ménière's disease.
1. Orthostatic Hypotension: When a person stands upright, due to the force of gravity, approximately 500~1000ml of blood flows into the lower extremities, which can lead to decreased venous return, decreased cardiac output, and decreased blood pressure. Therefore, when changing positions upon waking up in the morning, the aforementioned symptoms may appear. These symptoms usually alleviate or disappear after lying down flat.
2. BPPV: The cause is unknown but may be related to accelerated otolith degeneration, decreased absorption capacity, and reduced otolith stability due to aging. Changes in hormone levels, calcium metabolism disorders, and osteoporosis may also be predisposing factors. When the patient's head moves to a specific position, transient dizziness and characteristic nystagmus may occur. Treatment can involve otolith repositioning maneuvers.
3. Ménière's Disease: It is an idiopathic endolymphatic hydrops disease of the inner ear. The main mechanism is an imbalance in the production and absorption of endolymph. Patients may also experience the aforementioned symptoms. Treatment can include medications such as Diazepam Tablets, Diphenhydramine Hydrochloride Tablets, and Difenidol Hydrochloride Tablets, as prescribed by a doctor.
Additionally, it could also be caused by conditions such as hypertension. It is crucial to seek medical attention promptly to avoid delaying treatment.
