I have a theory about my lipomas. I have just recently been diagnosed with hashimotos which is an auto immune disorder. Apparently having one auto immune disorder puts you at greater risk for other immune disorders. I believe cancerous tumors come from the immune system trying to contain and fight the cancer. And my theory is that lipomas come from the immune system targeting fat cells thinking they are bad invaders so they get contained just as a malignant tumor would. I have several lipomas on my lower arms and thighs. I have just been put on a gluten free diet by my doctor for my hashimotos as well as having to take selenium, probiotics and L glutamine daily. Anyways, I believe lipomas are just another auto immune disorder that just might also be fixed by diet and fixing gut issues since the immune system is tightly connected to gut health. Just my two cents.
