@eileenb1022 There are lots of things that can be toxic or things that can cause an immune response. It's like having a big bucket that you fill up with things your body doesn't like, and when you accumulate enough of it, the body reacts with an immune response like an allergy, or can attack it's own tissues in an autoimmune response. Toxic things are stored in the body in different places because they are not easily eliminated, and those can be a root cause of why the body attacks itself in an autoimmune disease. My thyroid condition was an autoimmune condition, and after toxic metals were removed from my body, the autoimmune condition improved. That is evidence according to my doctor that the silver dental fillings were causing it. They contain silver, tin and mercury (which is very toxic) and when they break down with age and wear, mercury gas leaches out exposing the person to toxic vapors. Have you heard of mercury contamination in fish, and how doctors recommend not eating a lot of larger fish at the top of the food chain since mercury will accumulate in the larger fish?

In root canals, they used a compound called gutta percha which contains cadmium, a heavy metal. Heavy metals are hard to eliminate from the body. Lead is a heavy metal, and you have probably heard of lead poisoning from a person eating lead. It was used in paint years ago and kids were chewing on peeling paint chips causing lead poisoning, so lead was removed from paint. In my a case, with a failing root canal, the bone in my jaw was exposed to the bacterial infection in the tooth and the cadmium which could enter my blood.

I was just sharing information that comes from environmental medicine regarding autoimmune conditions. Some doctors will tell you they don't know what causes the body to attack itself, and others will point to a known or suspected cause. Your doctor will need to advise you as to what they think may be causing your symptoms. You mention your low thyroid function which I have too, and mine is definitely connected to mercury exposure from dental amalgam. My blood work confirmed it with before and after measurements of antibodies that were attacking my thyroid. Perhaps you don't have any of these dental fillings. In the 60's and 70's there were not many other materials that could be used for filling cavities. Perhaps your thyroid condition has a different cause.

Food allergies can be completely separate from toxic substances, but my experience suggests that by removing toxic metals, my food allergies and seasonal allergies with asthma improved a lot. If you think back to the "bucket', I was able to empty some of that stuff and my health improved. This is something a naturopath may discuss. Detox diets are common recommendations from alternative medicine providers. The body has specific detox pathways that either work well if you are healthy or maybe not so well when there is disease.

Have your doctors linked your gall bladder issues with diet? Have they recommended lists of foods to be avoided since your surgery?
