The BioHeal Ottawa Lyme Institute

The BioHeal Ottawa Lyme Institute is a cornerstone of the clinics’ operations. Lyme is a debilitating disease which for some reason has become politicized making it doubly hard for those afflicted with it to get thoughtful, unified treatment across the country.

As a tireless champion for those suffering from Lyme disease and coinfections, Dr. Marie Matheson, ND, has brought her considerable knowledge and training to BioHeal Ottawa. What's more, we've assembled a team of practitioners with strong credentials and driving interest in chronic conditions, including Lyme disease, to offer you and your family the best care possible.

Lyme Disease & Co-Infections


Lyme Disease and Co-Infections

Lyme disease is an illness caused by the bacterium, Borrelia burgdorferi, which can be spread through the bite of certain types of ticks (other possible vectors include fleas, spiders, mosquitoes, etc.). Ticks feed on deer, mice and migratory birds, which play a role in spreading the geographic footprint where the Lyme disease bacteria can be found.

The more basic description of Lyme disease, however, is that it is not straight forward to treat. IT mimics a great many other illnesses and for that reason there is no “one treatment” for all. A good Lyme doctor will need to tailor make a treatment to each individual.

When doctors insist on treating only if a positive testing result occurs, patient treatments are often delayed, leading to a worsened condition.  This is especially true when the treatment is based solely on the often-inconclusive “Elisa” test.

At this time, Lyme is still best treated based on clinical evidence. As a patient, this is the fork in the road to be concerned about as it will easy to tell a seasoned expert from a health care practitioner who is in over their heads. It takes years of extra education, training and patient visits to help patients make sense of all the symptoms they have and know which to treat first.

Dr. Marie and the doctors at BioHeal Ottawa will use a multi-faceted approach for this multi- factorial illness. We are not opposed to the use of antibiotics in treatment but specialize in treating exclusively with natural therapies, for those who either have plateaued with antibiotics, had unwanted side effects or believe that their bodies have a better response with natural products. Choices are made with the patient and your BioHeal doctor working as a team.

Chronic Illness


Chronic Illness

One way or another chronic illnesses are born of, or heavily contributed to by, chronic infections (and toxicity). The conventional medical arena has ‘labelled’ illnesses, like Parkinson’s Disease, Multiple Sclerosis, or Chronic Fatigue Syndrome, but in the end, all are established, primarily, from chronic infections (and toxicity), within their particular expression of it. At BioHeal Ottawa, we treat the underlying causes of chronic conditions in an effort to clean the terrain of your body from which disease states are able to take root and progress.

  • Lyme Disease & Co-Infections
  • Chronic Fatigue Syndrome
  • MS
  • Parkinson’s Disease
  • Neurological conditions
  • Crohn’s / Colitis / IBS
  • Scleroderma
  • Vitilago
  • Autoimmune

Limbic System Injury


Limbic System Injury

It’s virtually impossible to be in a chronic state of illness and not have emotional implications. Perhaps the other way of seeing this is that chronic stress responses often lead to dysregulation of the Limbic System.

The limbic system is a complex area of the mid-portion of the brain that attaches emotional responses to all the inputs we feel in our body through all our senses. It is completely integrated with the immune system and the nervous system. This means that, when illnesses progress from acute phase and into chronic stages or eventually into autoimmune stages, the body may have already created miles of negative neuro-pathways that were born due to the body’s innate protective mechanism that is the limbic system.

But, when impaired, the limbic system can become hypersensitive and send inappropriate signals to many of the body’s health systems, leading to symptoms that seem out of sorts and overly dramatic. Over a longer term, this condition of hyper sensitivity can further destabilize the entire immune system.

Fortunately, there are ways to treat limbic system dysregulation and many of the witnessed results are dramatic for the patient.

Autoimmune Illness


Autoimmune Illness

Autoimmune phenomena are identified as occurrences where the body’s own immune system mounts an attack against the very body it is there to protect by way of incessant, yet abnormal, inflammatory responses. It is as if contact with a once real infection incorrectly imprinted on the immune system whereby it thinks that the infection is ever present in the body, even after tests indicate it has been eliminated, and mounts ongoing reactions to otherwise healthy tissues within the body. The ongoing attack can lead to devastating damage within the body.

Fortunately, there are now treatments to rebalance your body’s immune response to various factors … like resetting a system … that put out the overreacting immune response.
