"The fight-or-flight system is hardwired for us humans to manage dangerous situations, and those of us with anxiety have an activated fight-or-flight response when the trigger is not really dangerous," says Beth Salcedo, MD, the medical director of The Ross Center for Anxiety & Related Disorders and board president of the Anxiety and Depression Association of America.
The effects of anxiety on the body Anxiety is a common condition that impacts a person's mental health, and it can also have short- and long-term effects on the body. Anxiety can change the function of the cardiovascular, urinary, and respiratory systems. It can also lead to digestive issues and an increased risk of infection. Learn more here. Read now
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.
Shortness of breath and chest pain are the predominant symptoms. People experiencing a panic attack may incorrectly attribute them to a heart attack and thus seek treatment in an emergency room. Because chest pain and shortness of breath are hallmark symptoms of cardiovascular illnesses, including unstable angina and myocardial infarction (heart attack), a diagnosis of exclusion (ruling out other conditions) must be performed before diagnosing a panic attack. It is especially important to do this for people whose mental health and heart health statuses are unknown. This can be done using an electrocardiogram and mental health assessments.
Anxiety attacks can last anywhere between a few moments to 30 or more minutes. It’s also common for subsequent anxiety attacks to follow, causing the overall anxiety attack experience to last much longer as one episode is followed by another. Even though anxiety attacks eventually end, it’s common for the symptoms and after effects of an anxiety attack to linger for hours or even days, depending upon the severity of the attack and the level of stress your body is under.
Moreover, this hypocapnia and release of adrenaline during a panic attack cause vasoconstriction resulting in slightly less blood flow to the head which causes dizziness and lightheadedness. A panic attack can cause blood sugar to be drawn away from the brain and toward the major muscles. Neuroimaging suggests heightened activity in the amygdala, thalamus, hypothalamus, and brainstem regions including the periaqueductal gray, parabrachial nucleus, and Locus coeruleus. In particular, the amygdala has been suggested to have a critical role. The combination of high arousal in the amygdala and brainstem along with decreased blood flow and blood sugar in the brain can lead to dramatically decreased activity in the prefrontal cortex region of the brain. There is evidence that having an anxiety disorder increases the risk of cardiovascular disease (CVD). Those affected also have a reduction in heart rate variability.
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.
