Whipple's isease is a rare, systemic infectious disease caused by the bacterium Tropheryma whipplei. First described by George Hoyt Whipple in 1907 and commonly considered a gastrointestinal disorder, Whipple's disease primarily causes malabsorption but may affect any part of the body including the heart, lungs, brain, joints, and eyes. Weight loss, diarrhea, joint pain, and arthritis are common presenting symptoms, but the presentation can be highly variable and approximately 15% of patients do not have these classic signs and symptoms. Whipple's disease is significantly more common in men, with a striking 87% of patients being male. When recognized and treated, Whipple's disease can usually be cured with long-term antibiotic therapy; untreated the disease is ultimately fatal.
