Treating & Understanding Autoimmunity
AUTOIMMUNITY – Stop the body’s attack on itself!
Autoimmunity or autoimmune conditions, relate to diseases (of which there are more than 80), where the immune system is attacking the body’s own healthy tissues and cells. This insult on the body by the immune system could be localized, to a specific organ or it could be systemic, effecting various parts of the body. This can change the way an organ or body systems functions and can cause damage and inflammation, resulting in many different symptoms.
CAUSES of AUTOIMMUNITY
Understanding Your Immune System
Our immune system produces antibodies (also known as immunoglobulins) in response to antigens (foreign substance such as bacteria and viruses), this allows our immune system to easily identify and destroy a particular antigen. In autoimmunity the immune system produces antibodies against the nucleus of the body’s own cells, these antibodies are known as autoantibodies or antinuclear antibodies (ANA’s). It’s important to note that not all autoimmune conditions cause ANA levels to rise.
A blood test can determine the presence of ANA’s, if positive it will be commonly reported as a titre, starting weak, moving to higher titres, examples include 1:80, 1:160, 1: 320, 1: 640, 1: 1280, etc etc, the value along with clinical signs and symptoms provides significance to a positive result and progression of disease. ANA test results can be positive in people without any sign and symptoms of autoimmune disease and you may find that medically this not considered relevant. Considering that ANA’s can be present years before signs or symptoms appear, we consider that any ANA should not be dismissed and all the appropriate investigation begin, rather than a “wait and see” approach! A positive ANA will prompt further testing which may be able to narrow down autoimmunity in specific tissues such as thyroid antibodies etc.
What To Test?
It is really important to test certain areas which may be causing the problem or may help treat your autoimmune condition, we have a list of our non-negotiable tests and then others that we may add later if needed. Many times it can be really useful to improve certain nutritional markers, provide certain support and improve digestion and then move on to the next test if and when needed. Examples of some tests: ANA, vitamin D, thyroid antibodies, estrogen, prolactin, anion gap, white cells, inflammatory markers, zinc, selenium, mercury, lead, cadmium, stool tests (parasites, bacterial overgrowth, yeast, microbiome, short chain fatty acids), immunoglobulins, breath tests (Helicobacter pylori, small intestinal bacterial overgrowth SIBO), viruses just to name a few! With heavy metal testing we need to decide if we want to check current exposure or past exposure. With all the testing, we like to start with easily accessible and inexpensive testing first, work in with GP’s when needed and then move on from there. Autoimmune diseases will involve lifestyle changes and depending on the severity of the situation will depend on the extent of changes needed, it is certainly an area that is dependant on lifestyle medicine. With the correct testing treatment can be directed on the areas that will have the best impact.
