Physical Effects of Anxiety and Depression 

Nearly 20% of adults in the United States have some form of anxiety disorder, making it the most common mental illness with 40 million people affected every year. Depression and anxiety are often co-occurring, with nearly 50% of those diagnosed with depression also having an anxiety diagnosis and vice versa, according to the Anxiety and Depression Association of America.  

With many people reporting increased concern over their mental health due to the COVID-19 pandemic, it’s important to understand that both anxiety and depression are treatable. Oftentimes, the earliest signs of anxiety and depression can be physical. Left untreated, both mental illnesses can contribute to significant physical health concerns.  

Causes of anxiety and depression 

  • Anxiety: Everyone faces stress in their lives, but certain types of stress can increase your chances of developing an anxiety disorder that will need treatment. These include trauma experienced as a child or adult, illness-related stress, prolonged stress or worry about a situation and underlying personality traits. As mentioned previously, having depression or other mental health disorders increases your risk for having an anxiety disorder, as does a family history and drug or alcohol misuse. 
  • Depression: There are many possible causes for depression including the brain’s regulation of chemicals and mood, family history and certain medications. Stressful life events and circumstances can also be a factor. Having other mental health disorders also increases the risk for depression.
