The relationship between changes in barometric pressure and dizziness has been described in medical literature, particularly in patients suffering from migraine related vertigo and Ménière’s disease. Both of these vestibular disorders are characterized by an episodic nature. This means that the symptoms come and go, in spells. For some people, these episodes can be triggered by changes in atmospheric pressure, such as weather changes before a storm or travelling from sea level to higher altitude. Read our post on Facebook about this topic. You mention the recurrent nature of your dizziness – vestibular neuritis is not classically recurrent like you describe. It is usually caused by a single viral or bacterial attack on the vestibular nerve. Symptoms typically start quite suddenly and may include severe vertigo and vomiting lasting for several hours. This is due to a loss in function of the vestibular nerve that can be temporary or permanent. During the recovery stage, which can last for several weeks, symptoms gradually improve and plateau. We recommend speaking to your family doctor and/or your ENT doctor (otolaryngologist) about the episodic/recurrent nature of your dizziness and vasovagal spells. Further investigation may be warranted into their cause.
