Causes of Anxiety

People can experience anxiety for all sorts of reasons. And doctors don’t fully understand what causes the condition. In some cases, anxiety may be linked to underlying health problems. If your doctor thinks your anxiety may have a medical cause, they may order further tests. Some examples of medical causes are:

  • Heart disease
  • Diabetes
  • Thyroid problems (hyperthyroidism)
  • Respiratory disorders, like chronic obstructive pulmonary disease (COPD) or asthma
  • Substance abuse or withdrawals
  • Withdrawal from alcohol, anti-anxiety medications (benzodiazepines) or other medications
  • Chronic pain or irritable bowel syndrome (IBS)
  • Rare tumors that release certain fight-or-flight hormones


A mental health professional will ask about your symptoms and determine whether you have anxiety. They will use the criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published by the American Psychiatric Association, to help make the right diagnosis.


The main treatments for anxiety disorders are psychotherapy and medications. These different treatment plans will help you to get back to your daily activities.


Known as talking therapy or psychological counseling, psychotherapy involves working with a therapist or counselor to help reduce your anxiety symptoms.

Cognitive Behavioral Therapy (CBT)

Cognitive behavioral therapy is the most effective form of psychotherapy for anxiety disorders. It focuses on teaching you specific skills to reduce or eliminate your symptoms. This therapy will help you to gradually return to the activities you may have avoided. CBT includes exposure therapy, in which you gradually encounter the object or situation that triggers your anxiety. This allows you to build confidence that you can manage the situation and symptoms.


Certain antidepressants are used to treat anxiety disorders. An anti-anxiety medication called buspirone may be prescribed. In some circumstances, your doctor may prescribe other types of medications, such as sedatives, also called benzodiazepines, or beta blockers. These medications are for short-term relief of anxiety symptoms and are not intended to be used for a long-term treatment plan.
