Why do I feel dizzy on the left side of my brain but not on the right?

Generally, dizziness occurring on the left side of the brain but not on the right may be caused by factors such as hypoglycemia, benign paroxysmal positional vertigo (BPPV), or vestibular migraine, and symptoms can be relieved through medication or physical therapies.

1. Hypoglycemia: Hypoglycemia may result from an improper diet structure, malnutrition, or similar factors, potentially causing symptoms such as dizziness localized to the left side of the brain, muscle twitching, and other discomforts. Medications like dexamethasone acetate tablets or calcium gluconate zinc oral solution may be used under medical guidance for symptom relief.

2. Benign Paroxysmal Positional Vertigo (BPPV): BPPV may be triggered by head trauma, ischemia of the internal auditory artery, or other factors, leading to symptoms such as dizziness affecting the left side of the brain but not the right, nausea, and other discomforts. Treatments include repositioning maneuvers and vestibular habituation exercises.

3. Vestibular Migraine: Vestibular migraine may be caused by high levels of mental stress, irregular eating habits, or similar factors, resulting in symptoms such as one-sided dizziness (left-side only) and blurred vision. Medications such as betahistine hydrochloride tablets or difenidol hydrochloride tablets may be used under medical supervision to alleviate symptoms.
