Lyme Disease and Autonomic Neuropathy
Lyme Disease and Autonomic Neuropathy Lyme disease, caused by the bacterium Borrelia burgdorferi and transmitted through tick bites, is often recognized for its hallmark symptoms such as erythema migrans (the classic bull’s-eye rash), fever, fatigue, and joint pain. However, beyond its initial presentation, Lyme disease can have long-lasting, complex effects on various bodily systems, including the nervous system. One of the less commonly discussed but significant neurological complications is autonomic neuropathy, which can profoundly impact a patient’s quality of life.
Lyme Disease and Autonomic Neuropathy Autonomic neuropathy refers to damage or dysfunction of the autonomic nervous system, the part of the nervous system responsible for involuntary bodily functions such as heart rate, blood pressure regulation, digestion, temperature control, and bladder function. When Lyme disease infects the nervous system—a condition known as neuroborreliosis—it can trigger inflammation and damage that extend into these autonomic pathways. The result can be a range of symptoms that are often misunderstood or misdiagnosed, including dizziness, fainting, abnormal sweating, gastrointestinal disturbances, urinary problems, and cardiovascular irregularities.
The pathophysiology behind Lyme-associated autonomic neuropathy involves the spirochete’s ability to invade the central and peripheral nervous systems. Once inside, it causes inflammation and immune responses that can damage nerve fibers, including those of the autonomic nervous system. This damage disrupts normal nerve signaling, leading to dysautonomia, or malfunction of autonomic functions. The variability of symptoms depends on the extent and location of nerve involvement, making diagnosis challenging. Lyme Disease and Autonomic Neuropathy
Lyme Disease and Autonomic Neuropathy Patients with Lyme-induced autonomic neuropathy often report a constellation of symptoms that can fluctuate throughout the day. Some may experience orthostatic hypotension—a sudden drop in blood pressure upon standing—leading to dizziness and fainting. Others might have abnormal heart rhythms, gastrointestinal issues like naus
ea, bloating, or constipation, and temperature regulation problems, such as excessive sweating or inability to sweat properly. These symptoms can significantly interfere with daily activities, social interactions, and mental health.
Diagnosis of autonomic neuropathy linked to Lyme disease requires a comprehensive clinical evaluation. Blood tests that confirm Borrelia infection, combined with neurological assessments and autonomic function tests—such as tilt-table testing, heart rate variability analysis, and sweat tests—help establish the connection. It is crucial for healthcare providers to consider Lyme disease in patients presenting with unexplained autonomic symptoms, especially in endemic areas or following possible tick exposure.

Lyme Disease and Autonomic Neuropathy Treatment approaches focus on eradicating the infection with appropriate antibiotic therapy, which can help reduce ongoing inflammation and prevent further nerve damage. Additionally, managing symptoms of autonomic dysfunction may involve medications to stabilize blood pressure, improve gastrointestinal motility, or regulate heart rhythm. Supportive therapies, including physical therapy and lifestyle modifications, are also vital in improving patient outcomes.
Understanding the link between Lyme disease and autonomic neuropathy emphasizes the importance of early detection and comprehensive care. Patients experiencing persistent, unexplained autonomic symptoms should seek medical attention, particularly if they have a history of tick exposure or reside in endemic regions. By addressing both the infection and its neurological consequences, healthcare providers can help restore function and enhance quality of life for those affected by this complex disease process.
