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?

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.).

I have had 7 infections so far this year, most viral like cold and gastroenteritis. I never need treatment. But I'm concerned I have immune problem?!

I have had 7 infections so far this year, most viral like cold and gastroenteritis. I never need treatment. But I'm concerned I have immune problem?!

Immunodeficiency: If you have had infections which resolved spontaneously it would be very improbable that they are due to some defect in immune function. Generally these would seldom resolve if your immune system was at fault. If you are concerned about HIV disease the best thing to do would be to go and be tested. If this is somatization and anxiety a therapist might be helpful. Good luck. Read more

Immune: If you had the same virus and you have recovered and you have a normal immune system, you should be immune and not susceptible from transmission of that virus back to you. (by the way, the best name for this is gastroenteritis. It's not really the flu because it is highly unlikely that the virus causing these symptoms is an influenza strain.). Read more
