According to your book, people who suffer from anxiety and depression usually find that stress can aggravate symptoms of other diseases. What specific disorder does your book say can be a result of stress, according to scientists?

Autoimmune disorder

Explanation:

An autoimmune disorder occurs when the body's immune system attacks and destroys healthy body tissue by mistake.

The blood cells in the body's immune system help protect against harmful substances. These substances contain antigens. The immune system produces antibodies against these antigens that enable it to destroy these harmful substances.

When you have an autoimmune disorder, your immune system does not distinguish between healthy tissue and potentially harmful antigens. As a result, the body sets off a reaction that destroys normal tissues.

Stress Can Be Especially Detrimental to those with Autoimmune Diseases.

A new study has found an association between stress-related conditions such as anxiety and post-traumatic stress disorder (PTSD) and autoimmune diseases such as type 1 diabetes, celiac disease, and rheumatoid arthritis (RA).
