Overactive Immune System Symptoms
Infection & cancer: Your immune system works by recognizing when stuff in your body is different from you. Then it gets rid of that stuff. Such foreign stuff includes pathogens that cause infections like bacteria & viruses & normal cells that mutate into cancerous ones. So signs of a weak immune system are recurrent infection - usually respiratory or gastrointestinal - & decreased surveillance of cancerous changes. ...Read more

Why is a person with autoimmune more susceptible to the common cold? An overactive immune system should fight it off?
Good question: Ironically people with autoimmune diseases have an immune system that is reved up against normal parts of the body yet also is not efficient at fighting infections such as viruses that cause the common cold. Also many patients are on medications that suppress the normal immune response to infections such as prednisone, methotrexate, enbrel, humira, or remicade (infliximab). ...Read more

No difference: Sorry to burst any bubbles about diet, infections, and the immune system. But the foods you eat or avoid will make no difference in your cold symptoms or how quickly it clears up. Just maintain a normal diet, with increased fluids if you have fever. Whatever tastes good and goes down easy will be just fine. ...Read more
Does Crohn's cause an overactive immune system or does an overactive immune system cause Crohn's? Stay away from foods that boost the immune system?
Roque immune system: I think one need to think more about a rogue immune reaction thereby causing autoimmune disorder instead of an overactive one. An autoimmune problem happens when the immune system malfunctions and starts attacking one's own tissue thereby leading to illnesses such as Crohn's disease, lupus etc. ...Read more
If the immune system mediated attack on peripheral nerves why would the human body not feel this rather giving symptoms months later when damage done?
Actually, you do...: The pain felt when one has a skin/soft tissue infection or autoimmune process is partly associated with pain receptors of nerves being activated. In certain processes, destruction of painreceptors is felt as "pins and needles" ("peripheral neuropathy").The delay you describe, may be due to other nerves that process the pain signal that are involved in the central nervous system. ...Read more
I hear autoimmune disorders described as an overactive immune system. Does that mean those people can never get sick?

Is it true that terrible cold symptoms are the product of a strong immune system, rather than a weak one? Thank you :)

What could be the reasons why you can have flu without fever? Is it a symptom of having a problem with the immune system?
Everyone is differen: Viral infection affects people in different ways. Some people may not even have symptoms, others become very ill. The fever is the result of the body mounting an immune response to the viral invasion and may possibly be related to how much is viral load is as well as how the body handles the invasion. ...Read more
If you don't get gastroenteritis for years does the immune system become less efficient at fighting it and thus causing severe symptoms when infected?
Consider this...: Lots of things can cause GI distress to recur--incompletely treated infection (e.g. Giardia) or re-exposure with re-infection; maldigestion (pancreatic insufficiency) or malabsorption (celiac sprue); food intolerances with re-exposure to the offending substance (lactose, sorbitol, etc.), irritable bowel syndrome, missed diagnosis (incomplete evaluation), non-gi related problems (uti, pid, etc.). ...Read more
If the immune system mediated an aggressive attack on the whole peripheral nervous system and killed the entire nerves of the body what are symptoms?
Death: Although I just answered your question, important to understand that this would involve a rare progressive irreversible anaphylactic allergic reaction, and this really affects numerous organ systems. However, consider that there are chronic immune disorders that attack peripheral nerves (cidp), and nerves in central brain and spinal cord (ms). This is almost never an all or none situation. ...Read more
