Lyme disease is a complex condition that may lead to lingering symptoms long after the initial infection. Some individuals experience ongoing fatigue, joint discomfort, neurologic symptoms, or cognitive changes that do not fully resolve with standard care alone.

From a functional medicine perspective, evaluation often focuses on immune response, inflammation, detoxification pathways, and how the infection may have disrupted multiple body systems. Care is individualized and guided by clinical history, appropriate testing, and overall functional status rather than a single lab marker.
