Previous research has demonstrated a number of conditions, such as sleep disturbance, fatigue, depression, spastic colon and mitral valve prolapse, associated with fibromyalgia. The present report describes additional symptoms and medical conditions that appear to be associated with the syndrome based on a survey of 554 individuals with fibromyalgia compared with a group of 169 controls. Individuals with fibromyalgia self report a greater incidence of bursitis, chondromalacia, constipation, diarrhea, temporomandibular joint dysfunction, vertigo, sinus and thyroid problems. Symptomatic complaints found statistically more prevalent in fibromyalgia patients included concentration problems, sensory symptoms, swollen glands and tinnitus. Other associations occurring with significant increased frequency were chronic cough, coccygeal and pelvic pain, tachycardia and weakness. Our previous report on inheritance patterns in fibromyalgia was reaffirmed with 12% reporting symptomatic children and 25% reporting symptomatic parents. Of the respondents, 70% noted that their symptoms were aggravated by noise, lights, stress, posture and weather.

Mild mitral valve prolapse, hypoglycemia, irritable colon, and premenstrual syndrome are examples of anatomico-physiologic phenomena that largely overlap with normal. Such "overlap syndromes" become labeled disease entities by the medical community through a process called medicalization. This report uses mitral valve prolapse (MVP) to exemplify the effects of medicalization on patients, physicians, and society. Ascertainment bias and insufficient controlled clinical studies have led to the description of a clinical entity replete with false associations (e.g., mitral valve prolapse syndrome) and overly pessimistic prognostication (e.g., risk of sudden death or endocarditis), leading to clinical overreaction, overtreatment, and unnecessary induction of disability. Though some physical complications may be prevented by recognizing severe MVP, there is substantial risk of iatrogenic harm by attributing complex symptoms and illness behavior to mild MVP, which is probably a normal variant. A three-dimensional analysis of illness experience is presented that may be of use in conceptualizing the clinical approach to overlap syndromes such as mild MVP. Conservative criteria for the diagnosis of significant MVP have been developed at the National Institutes of Health. Treatment of patients with mild MVP must emphasize that it is a normal variant without serious consequences. Because the risks of overmedicalization are so substantial, the impact of diagnostic labels on individual patients and society must be analyzed continually.

Epidemiological studies have found significant comorbidity between panic disorder and many medical illnesses. The authors discuss the accumulating psychiatric and medical literature addressing comorbidity between panic disorder and cardiac, respiratory, gastrointestinal, and neurological illnesses. Cardiac symptoms such as chest pain and palpitations, as well as certain disorders such as mitral valve prolapse, hypertension, and cardiomyopathy, share significant comorbidity with panic disorder. Researchers have also shown significant comorbidity between panic disorder and chronic obstructive pulmonary disease, irritable bowel syndrome, and migraine headache. Pathophysiological mechanisms that may explain the association between panic disorder and comorbid medical illnesses, such as autonomic dysregulation of cardiac activity and smooth muscle tone and dynamic abnormalities of the coronary microvasculature, are discussed as well.
