Can Lyme Disease Cause Stomach Problems? Gastroparesis and GI Symptoms Explained
Can Lyme disease cause stomach problems? Yes. In some cases, Lyme disease can disrupt the autonomic nervous system, leading to nausea, vomiting, abdominal pain, reflux, and delayed stomach emptying known as gastroparesis.
In rare but serious cases, symptoms can become severe enough to require intravenous nutrition.

How Lyme Disease Affects the Digestive System
Lyme disease can disrupt the autonomic nervous system, which controls digestive motility.
When this system is impaired, patients may develop:
- Nausea and vomiting
- Abdominal pain and bloating
- Reflux
- Difficulty tolerating food
- Delayed gastric emptying (gastroparesis)
This reflects a motility problem—not just a stomach problem.
Case Report: Severe Gastroparesis in Lyme Disease
A 25-year-old woman with chronic Lyme disease developed progressive gastrointestinal symptoms that became life-threatening.
Her illness began with loss of appetite and progressed to:
- Constant nausea and vomiting
- Severe reflux and regurgitation
- Inability to tolerate solid food
She underwent gallbladder removal, but symptoms returned.
Eventually:
- A feeding tube was placed
- She required total parenteral nutrition (TPN) to maintain weight
Imaging showed delayed stomach and small intestine emptying—consistent with gastroparesis.
Despite multisystem illness, Lyme disease was not treated.
Why This Case Matters
This case highlights a critical pattern:
Multisystem symptoms were attributed to nerve damage—without considering ongoing infection.
Lyme disease is known to affect:
- The nervous system
- The immune system
- Autonomic regulation
When these systems are disrupted, gastrointestinal symptoms may become severe.

Could Persistent Infection Play a Role?
Some studies suggest Borrelia burgdorferi may persist after standard treatment.
Animal models have demonstrated viable organisms following antibiotic exposure.
While the clinical implications remain debated, this raises an important question:
Could ongoing infection contribute to persistent gastrointestinal symptoms?
Clinical Takeaway
Lyme disease can cause gastrointestinal symptoms—including gastroparesis—through autonomic dysfunction.
- Symptoms may include nausea, vomiting, reflux, and food intolerance
- Severe cases may require nutritional support
- Multisystem illness should prompt broader evaluation
Recognizing this pattern may help avoid delayed diagnosis and improve care.
Frequently Asked Questions
Can Lyme disease cause gastroparesis?
Yes. Autonomic nerve dysfunction can impair stomach motility.
Why are symptoms often missed?
They may be attributed to unrelated gastrointestinal conditions or nerve damage alone.
Can Lyme disease persist after treatment?
Some evidence suggests persistence in animal models, though this remains debated.

In 1999, my 7yo daughter had a known tick attachment. First symptom were persistent ankle pain At age 8, she had chronic constipation, resulting in 4 trips to ER and 2 overnight hospital admissions. More water and fiber were not effective remedies. At puberty at 12, her health collapsed. She had two Lyme bands and got IV treatment Tilt table at 14 got POTS dx. At 28yo, she remains disabled.
You are not alone. This article on autonomic dysfunction affords some insight into the potential role of autonomic dysfunction in Lyme disease.
I have had chronic Lyme for 4 yrs with terrible digestive problems.
I self diagnosed myself with Lymes after no one seemed to be able to figure it out. I had a total of 24 days of doxycycline and was pronounced cured. I originally had severe back pain in my right kidney area that has decreased significantly but still have a burning sensation in the left front flank area where my intestines are along with some joint pain. I’m taking Meloxicam for pain. I’ve been extremely tired and can’t seem to stay awake when in a vehicle. I don’t feel I’m over it and wondering if I’m ever going to feel normal again.
I have Lyme disease patients who are better in 24 days if they get treated at the time of a rash. I have patients who have failed 24 days who benefit from further treatment for Lyme and coinfections.
