Causes of chronic lightheadedness include migraines, anxiety, low blood sugar, dehydration and anemia, according to Mayo Clinic. Patients with medical conditions such as low blood pressure, labyrinthitis and benign paroxysmal positional vertigo also experience chronic lightheadedness.
Patients with low blood pressure experience dizziness after changing positions, eating or standing for a long period of time, notes Healthline. Other symptoms of low blood pressure include fainting, blurry vision, depression and nausea.
Labyrinthitis is an inner ear infection that is typically caused by a virus, explains MedlinePlus. Patients with the condition experience dizziness with vertigo, as well as nausea, vision problems and hearing loss. Doctors treat patients with labyrinthitis using medications that treat the symptoms, including antihistamines, antivertigo drugs and steroids. Lifestyle changes such as resting, avoiding sudden movements and balance therapy also help with managing the symptoms of labyrinthitis.
Benign paroxysmal positional vertigo, also known as BPPV, occurs when the buildup of calcium carbonate crystals within a tube in the inner ear responsible for balance becomes loose, according to Cleveland Clinic. Patients with the condition experience dizziness as a result of head movements, such as when sitting up in bed or rolling over. BPPV is treated using the particle repositioning procedure, which involves a patient performing movements that reposition that crystal buildup to its proper place.
