Autoimmune disease occurs when the immune system mistakenly identifies healthy cells as foreign and attacks otherwise healthy tissue. While conventional treatment approaches to autoimmune diseases often focus solely on symptom management, functional medicine strives to address the root causes of these conditions.
Common signs and symptoms of autoimmune conditions can include chronic fatigue, joint and muscle pain, digestive issues, skin changes or rashes, brain fog, swollen glands or tissues, dizziness, hair loss, nerve pain or tingling, weight fluctuations, and chronic headaches or migraines. Depending on the specific autoimmune condition and the individual, symptoms will vary.
Functional medicine seeks to understand the underlying factors that may influence the development or flare-ups of autoimmune diseases. Contributing factors can include infections, environmental exposures, gastrointestinal issues, inflammation, genetics, chronic stress, allergies or sensitivities, and other elements that may lead to immune system dysregulation. Identifying the underlying causes is not intended to provide a cure, but rather to offer a clearer understanding of what may be occurring in the body and to support more effective management.
How do functional medicine doctors determine what may be influencing autoimmune diseases?
Functional lab testing is commonly used to identify contributors to immune dysregulation. These tests may include chronic infection panels, mold toxicity testing, comprehensive stool analysis, organic acid testing, heavy metal screening, food and environmental allergy or sensitivity testing, adrenal studies, and standard blood work.

In addition to a thorough intake and testing process, functional medicine doctors may implement dietary and lifestyle changes, supplement protocols, and medications, all while addressing the underlying causes. By focusing on potential triggers and taking the individual into account, functional medicine providers strive to manage autoimmune conditions more effectively and sustainably.
