In addition to the emotional turmoil and the physical manifestations that Caroline and Kirstie describe panic attacks can cause palpitations, pounding heart or accelerated heart rate; sweating; trembling or shaking; sensations of shortness of breath or smothering; feelings of choking; chest pain or discomfort; nausea or abdominal distress; feeling dizzy, unsteady, light-headed or faint; chills or overheating; numbness or tingling; feelings of unreality (derealization) or being detached from oneself (depersonalization); fear of losing control or “going crazy”; and fear of dying.
Given that anxiety attacks aren’t specifically outlined as a diagnosis in the DSM-5, the usage of the word is open to interpretation and different individuals may use it in varying ways and circumstances. For one person, an anxiety attack might be overthinking about a specific worry to the extent that they are unable to concentrate on anything else; for another, anxiety attack might refer to sweating and shortness of breath when faced with a certain situation.
Panic attacks may also be caused by substances. Discontinuation or marked reduction in the dose of a substance such as a drug (drug withdrawal), for example an antidepressant (antidepressant discontinuation syndrome), can cause a panic attack. According to the Harvard Mental Health Letter, "the most commonly reported side effects of smoking marijuana are anxiety and panic attacks. Studies report that about 20% to 30% of recreational users experience such problems after smoking marijuana."
A panic attack may be a one-time occurrence, although many people experience repeat episodes. Recurrent panic attacks are often triggered by a specific situation, such as crossing a bridge or speaking in public—especially if that situation has caused a panic attack before. Usually, the panic-inducing situation is one in which you feel endangered and unable to escape, triggering the body’s fight-or-flight response.
If you have anxiety that’s severe enough to interfere with your ability to function, medication may help relieve some anxiety symptoms. However, anxiety medications can be habit forming and cause unwanted or even dangerous side effects, so be sure to research your options carefully. Many people use anti-anxiety medication when therapy, exercise, or self-help strategies would work just as well or better—minus the side effects and safety concerns. It’s important to weigh the benefits and risks of anxiety medication so you can make an informed decision.
People with generalized anxiety disorder (GAD) display excessive anxiety or worry, most days for at least 6 months, about a number of things such as personal health, work, social interactions, and everyday routine life circumstances. The fear and anxiety can cause significant problems in areas of their life, such as social interactions, school, and work.
