This is another root cause situation. For autoimmune disease to occur, there are 3 factors that need to be present.
Environmental triggers that turn on the gene
While we can't change number 1, there are things we can do about numbers 2 and 3. For example, autoimmune disease goes hand in hand (in hand) with digestive imbalances, gut infections, and food allergies/sensitivities/intolerances (which can serve as an environmental triggers).
Problems in our guts can cause inflammation there. This upsets the delicate lining of the gastrointestinal tract. That lining is only one cell layer thick! Those cells are held together by tight junctions. Inflammation causes those junctions to become loose, and then we have leaky gut.
Food particles that are not completely digested are able to leak out, and they end up in our blood stream. They are not supposed to be there so our immune system begins to respond. Overtime this heightened immune response can begin to target any area of the body. In the lungs, we can get asthma, in the joints we can get arthritis (rheumatoid and psoriatic) and in the skin we can get atopic dermatitis and psoriasis. These are just some examples of conditions that can be tied to gut issues. You might not even have gastrointestinal symptoms, so while all this is happening, you are unaware of the problems brewing in your gut.
What can be done? Addressing the underlying causes can lessen symptoms and help control progression of your condition. The plan includes:
Using a comprehensive digestive stool analysis to identify gut infections
Getting tested for food allergies and sensitivities
Working with a professional to guide you appropriately, there is no one size fits all approach, you are an individual and a personalized plan must be developed for you based on appropriate assessment of your history, present situation, goals you have for your future, and appropriate testing (like the two mentioned above)
