Whipple’s disease is a rare infectious disease. It is caused by a bacterium named Tropheryma whippleii.

Whipple’s disease is caused by a specific type of bacteria. This bacterium causes abnormal changes on the wall of the small intestine. These changes disrupt the villi. Villi are tiny, finger-like structures that stick out from the wall of the intestine to help absorb nutrients. As a result, some nutrients are not absorbed properly and do not reach the rest of the body.
