Because involuntary panic attacks can be caused by other medical conditions, such as mitral valve prolapse, thyroid problems, hyperglycemia, side effects from certain types of medications, recreational drug use (such as marijuana), stimulants, etc., it’s best to discuss your panic attacks and symptoms with your doctor to rule out any medical cause.
The degree of accompanying stress response and its physiological, psychological, and emotional changes are directly proportional to the degree of anxiety. For example, if you are only slightly concerned, such as being slightly nervous about meeting someone new, the body produces a small degree stress response. The small degree stress response can be so slight that you don’t even notice it.

People who have repeated, persistent attacks or feel severe anxiety about having another attack are said to have panic disorder. Panic disorder is strikingly different from other types of anxiety disorders in that panic attacks are often sudden and unprovoked.[18] However, panic attacks experienced by those with panic disorder may also be linked to or heightened by certain places or situations, making daily life difficult.[19]
Shortness of breath is a common symptom of panic attacks that can make you feel frantic and out of control. Acknowledge that your shortness of breath is a symptom of a panic attack and that this is only temporary. Then begin by taking a deep breath in for a total of four seconds, hold for a second, and release it for a total of four seconds. Keep repeating this pattern until your breathing becomes controlled and steady. Focusing on the count of four not only will prevent you from hyperventilating, but it can also help to stop other symptoms in their tracks.
The cause of anxiety disorders is a combination of genetic and environmental factors.[47] Anxiety can stem itself from certain factors: genetics, medicinal side-effects, shortness of oxygen.[48] Risk factors include a history of child abuse, family history of mental disorders, and poverty. Anxiety disorders often occur with other mental disorders, particularly major depressive disorder, personality disorder, and substance use disorder.[49] To be diagnosed symptoms typically need to be present at least six months, be more than would be expected for the situation, and decrease functioning.[10][49] Other problems that may result in similar symptoms including hyperthyroidism, heart disease, caffeine, alcohol, or cannabis use, and withdrawal from certain drugs, among others.[49][7]
Panic attacks can happen during the day or night. Some people have one panic attack then don't ever experience another, or you might find that you have them regularly, or several in a short space of time. You might notice that particular places, situations or activities seem to trigger panic attacks. For example, they might happen before a stressful appointment.
If constant worries and fears distract you from your day-to-day activities, or you’re troubled by a persistent feeling that something bad is going to happen, you may be suffering from generalized anxiety disorder (GAD). People with GAD are chronic worrywarts who feel anxious nearly all of the time, though they may not even know why. Anxiety related to GAD often shows up as physical symptoms like insomnia, stomach upset, restlessness, and fatigue.

If you are greatly afraid, however, such as being terrified that there is a burglar in your home that is about to harm you, the body produces a high degree stress response. We generally experience high degree stress responses as being anxiety attacks: where the changes are so profound they get our full attention. The greater the degree of anxiety and stress response, the more changes the body experiences.
Dialectical Behavior Therapy (DBT) is form of Cognitive therapy that emphasizes individual psychotherapy as well as group skills training to help people learns new skills and strategies—including mindfulness and distress tolerance– to manage their anxiety and panic.  According to the American Psychological Association therapists who practicing DBT aim to strike a balance between validation and change by clearly communicating acceptance of who the client is and the challenges the client faces, while at the same time helping the client to learn new skills to improve emotion regulation, interpersonal communication skills and how to participate in life and cope with problems without defaulting to impulsive behavior.
Occasional anxiety is an expected part of life. You might feel anxious when faced with a problem at work, before taking a test, or before making an important decision. But anxiety disorders involve more than temporary worry or fear. For a person with an anxiety disorder, the anxiety does not go away and can get worse over time. The symptoms can interfere with daily activities such as job performance, school work, and relationships.
