Yes, stress can trigger and worsen vertigo associated with anxiety. Vertigo is the sensation that the room is spinning, and is a form of dizziness. Dizziness is where you are off-balance, feel like you are going to faint, or feel light-headed. Vertigo is a symptom of vestibular system dysfunction. The vestibular system is located in the inner ear, and it helps you with balance. If you have vertigo and go to the doctor, and the physical examination and laboratory tests come back as normal, then anxiety may be the problem. The problem is that patients with vertigo or dizziness are often referred to specialists, like ENT doctors or neurologists, and when the medical workup is negative, these patients are not referred back to psychiatry for follow-up. This highlights the lack of multidisciplinary treatment of patients who have psychiatric illness with physical symptoms. This is unfortunate, as anxiety disorder, specifically panic disorder with or without agoraphobia, is highly associated with dizziness (Caliman e Gurgel et al., 2007). Sadly, psychiatry is viewed in the medical community with much stigma, and contributes to psychiatry operating at the fringes of medicine and not being fully integrated within it, contributing to the lack of collaborative treatment.
Another study found that patients with dizziness and panic attacks had higher rates of vertigo and agoraphobia compared to those patients who had either dizziness or panic attacks alone (Yardley et al., 2001). So if you have vertigo or dizziness as a main symptom of panic disorder with or without agoraphobia, this may perpetuate avoidant behaviors, as you would likely have worries that you would get dizzy and receive no help, if you were to leave your home. Vertigo associated with anxiety can have devastating consequences, as you most likely have to quit your job and break-off relationships due to your avoidant behaviors and/or agoraphobia.
So stress can trigger or exacerbate your anxiety, and this may lead to vertigo or dizziness. The treatment for vertigo associated with anxiety is to first have patient education, that the vertigo is an anxiety symptom, rather than a physical symptom of a vestibular disorder or other medical disorder. Then you would have the underlying anxiety disorder treated, with vertigo being most associated with panic disorder. A psychiatric consultation may be warranted here, to consider prescription medication treatment for the panic disorder. Also, cognitive behavior therapy would be helpful to address the avoidant behaviors and the maladaptive thinking and coping style. If you prefer self-help methods, then Anxiety Protocol and/or KalmPro can be helpful to eradicate the anxiety.
