Many people who learn about Lyme disease wonder about its causes and whether family members could inherit it. A common question patients ask is this: “Is Lyme disease genetic?”
The short answer is no — Lyme disease itself is not genetic. You cannot inherit the infection directly from your parents through DNA. However, your genetics may still influence how your body responds to infections and inflammation. Some people have genetic tendencies that make chronic symptoms more likely after infections like Lyme.
Understanding the difference between genetic risk factors and how Lyme disease actually spreads can help people better protect themselves and seek care if symptoms arise.
At Lindgren Functional Medicine in Green Bay, our care team works with patients to investigate complex chronic illnesses and underlying infections — including tick-borne diseases — through a root-cause, functional medicine approach.
What Causes Lyme Disease?
Although people sometimes wonder if Lyme disease runs in families, it is actually caused by a bacterial infection.
The illness develops when a person is infected with Borrelia burgdorferi, a bacterium transmitted through the bite of infected blacklegged ticks (often called deer ticks).
These ticks can carry the bacteria after feeding on infected animals such as mice or deer. When they attach to humans and feed for long enough, they can transmit the bacteria into the bloodstream.
This means Lyme disease is classified as a tick-borne illness, not a hereditary condition.
How Infection Typically Occurs
Most infections occur through…
- Tick bites during outdoor activities
- Contact with wooded or grassy environments
- Exposure in areas where infected ticks are common
Ticks are extremely small — often no larger than a poppy seed in early life stages — so people may not notice a bite.
Can Lyme Disease Be Passed Down Genetically?
Because Lyme disease is caused by bacteria, it cannot be inherited through your genes.
You cannot be born with the infection simply because a parent had Lyme disease in the past.
However, genetics can still play a role in how someone experiences illness.
Genetic Factors and Chronic Inflammation
Some individuals have genetic traits that influence…
- Immune system responses
- Detoxification pathways
- Inflammatory reactions
These differences may affect how the body responds to infections such as Lyme disease. For example, some people clear infections quickly, while others may experience prolonged inflammation or lingering symptoms.
Functional medicine practitioners often look at these genetic tendencies toward Lyme disease because they can help explain why two people exposed to the same infection may have very different outcomes.
At Lindgren Functional Medicine, practitioners emphasize that many health conditions — including chronic infections — are influenced by the interaction of genes, environment, and lifestyle.
Can Lyme Disease Be Passed from Mother to Baby?
Another important question related to the topic of whether Lyme disease is genetic involves pregnancy.
Lyme disease is not genetic, but researchers have explored whether the bacteria could be transmitted from a pregnant mother to her baby.
Current medical evidence suggests that…
- Transmission during pregnancy is rare
- Most pregnancies with treated Lyme disease result in healthy outcomes
However, untreated infections during pregnancy could theoretically increase certain risks.
Because of this, pregnant patients who suspect Lyme disease should seek prompt medical evaluation and treatment.
Healthcare providers may recommend testing and monitoring to ensure both mother and baby remain healthy throughout the pregnancy.
Everyday Lyme Exposure Risks in Wisconsin
People living in the Upper Midwest should be aware that Lyme disease exposure is relatively common in certain environments.
Wisconsin consistently reports some of the highest Lyme disease rates in the United States. The climate and ecosystems in the region allow ticks to thrive.
Areas around Green Bay include forests, wetlands, and recreational parks — beautiful places to hike and spend time outdoors, but also habitats where ticks can live.
Common exposure scenarios include the following:
- Hiking wooded trails
- Gardening or yard work
- Camping
- Hunting
- Walking dogs in tall grass
- Playing in wooded areas
Ticks often live in the following places:
- Leaf litter
- Tall grasses
- Shrubs and brush
- Forest edges
Because they wait on vegetation and latch onto passing animals or people, even brief outdoor activity can sometimes lead to exposure.
A Functional Medicine Perspective on Tick-Borne Illness
At Lindgren Functional Medicine, our team emphasizes personalized care for complex health concerns. Our philosophy centers on identifying the root causes behind symptoms rather than relying on one-size-fits-all treatments.
Patients may receive…
- Comprehensive health evaluations
- Advanced laboratory testing
- Individualized nutrition plans
- Lifestyle and stress-management strategies
- Targeted therapies designed to support healing
This whole-body approach can be particularly helpful for conditions influenced by inflammation, immune function, and environmental exposures.
Protecting Yourself from Lyme Disease
Although Lyme disease is not genetic, prevention remains important — especially in regions where ticks are common.
Simple precautions can significantly reduce risk.
Tick Prevention Tips
When spending time outdoors…
- Wear long sleeves and pants
- Use EPA-approved insect repellents
- Stay on clear trails when hiking
- Perform tick checks after outdoor activities
- Shower soon after coming indoors
- Check pets for ticks as well
Removing ticks quickly, preferably within 24 hours, reduces the likelihood of infection. If you find a tick attached to your skin, remove it as soon as possible using fine-tipped tweezers. Grasp the tick as close to the skin’s surface as possible and pull upward with steady, even pressure — avoid twisting or jerking, which can cause parts of the tick to break off in the skin. After removing the tick, clean the bite area and your hands with soap and water or rubbing alcohol. Dispose of the tick by placing it in alcohol, sealing it in a bag, or flushing it down the toilet.
When to Seek Medical Support
If you live in a tick-prone area and experience symptoms such as unexplained fatigue, joint pain, or flu-like illness after outdoor exposure, it may be worth discussing testing with a healthcare professional.
Early detection can make treatment simpler and more effective.
For individuals who continue to experience unexplained symptoms, a deeper investigation into immune function, inflammation, and environmental exposures may provide valuable insight.
Personalized Care at Lindgren Functional Medicine
So, is Lyme disease genetic? No. Lyme disease itself is caused by bacteria transmitted through tick bites, not by inherited genes. However, genetic factors may influence how your immune system responds to infections and inflammation.
If you are concerned about possible Lyme exposure, chronic symptoms, or other complex health issues, the team at Lindgren Functional Medicine in Green Bay, Wisconsin, offers a personalized approach designed to uncover root causes and support long-term wellness.
At Lindgren Health, practitioners take time to understand each patient’s health story and develop individualized plans that address underlying imbalances affecting the body.
