Gastrointestinal Symptoms of Lyme Disease
Gastrointestinal symptoms of Lyme disease may occur when infection affects the digestive system or disrupts normal immune and inflammatory responses. Some patients experience nausea, abdominal discomfort, diarrhea, or other digestive disturbances during Lyme illness.
Digestive symptoms may appear early in infection or develop later as the disease progresses. Because gastrointestinal complaints are common in many medical conditions, Lyme disease may not always be considered as a possible cause.
This page highlights gastrointestinal manifestations associated with Lyme disease and links to clinical articles discussing these symptoms in more detail.

Why Gastrointestinal Lyme Symptoms Are Often Overlooked
Digestive symptoms are frequently attributed to viral illness, food intolerance, or stress. As a result, Lyme disease may not initially be considered when patients present primarily with gastrointestinal complaints.

Editor’s note: In my clinical experience, gastrointestinal symptoms may occur in Lyme disease, although they are less widely recognized than neurologic or musculoskeletal manifestations.
