How much do genes and everyday life contribute to an autoimmune condition? It is an understandable question, especially when you are looking for something practical to do after a diagnosis.
What is an autoimmune condition?
Autoimmune conditions involve the immune system mistakenly attacking the body’s own tissues. They include different illnesses affecting different organs, such as type 1 diabetes and rheumatoid arthritis. Better Health Channel — Autoimmune disorders.
They need assessment and care suited to the particular condition. A general lifestyle article cannot tell you which condition you have or explain an individual diagnosis. Better Health Channel — Autoimmune disorders.
Why leave out the percentage?
The exact causes are not fully understood. Genetic susceptibility and other factors can contribute, and the pattern differs between conditions. Better Health Channel describes this complexity rather than assigning one fixed percentage to everyone. Better Health Channel — Autoimmune disorders.
You do not need to work out how much of an illness is your responsibility before asking for help.
Make food questions specific
Tell your clinician what you normally eat, any symptoms you have noticed and what changes you are considering. Ask whether you need a dietitian familiar with your diagnosis.
A general balanced diet includes grains, legumes and dairy or suitable alternatives, as well as vegetables, fruit and other protein foods. An individual medical diet needs its own discussion; the old article’s blanket exclusions are not a plan to follow. Healthdirect — A balanced diet.
Our everyday food ideas offer ordinary serving suggestions without disease claims.
Keep your medical team involved
Diagnosis can involve a medical history, examination and tests. Treatment varies with the condition and may include medicines and other care. Better Health Channel — Autoimmune disorders.
Bring questions about your diagnosis, current treatment and follow-up to your GP or specialist. This article does not recommend a supplement, exclusion diet or replacement for that care.
