Patients with generalized anxiety disorder (GAD) often have multiple medical comorbidities. The
adrenal system and genetic and environmental factors are intermediaries between anxiety and medical
illnesses such as chronic pain conditions and gastrointestinal, cardiovascular, endocrine, and respiratory
disorders. Medical disorders associated with anxiety include migraine, rheumatoid arthritis, peptic
ulcer disease, irritable bowel syndrome, coronary heart disease, hyperthyroidism, diabetes, asthma,
and chronic obstructive pulmonary disorder.
