What is a potential complication of untreated Lyme disease?

Untreated Lyme disease, which is caused by the bacterium Borrelia burgdorferi transmitted through tick bites, can lead to various complications if not addressed in a timely manner. One significant complication is carditis, which refers to inflammation of the heart tissue.

Lyme carditis typically manifests as atrioventricular (AV) block, which can lead to symptoms such as palpitations, dizziness, or syncope. In some cases, this condition can progress to more severe heart issues, necessitating medical intervention. It occurs due to the immune response to the Lyme infection, resulting in inflammation that affects the heart's electrical conduction system.

Recognizing carditis as a potential complication highlights the systemic nature of Lyme disease and the importance of early diagnosis and treatment. Addressing Lyme disease promptly can prevent the onset of such serious complications.
