Thank you very much for the useful information.
Some people have allergy issues and continuous/recurrent exposure to the allergens can lead to ongoing inflammation and secondary infections.
So if not already get your self screened for allergies (an immunologist is the right person to consult).
Also a condition in which the immune system does not work effectively, called common variable immune deficiency (CVID) is some thing which should be considered in a person who undergoes repeated infections. Again an immunologist is the right person to help you in this situation.
As far as strengthening of the immune system is concerned, one has to diagnose any pathology/problems in the immune system first, only which can direct a specific and targeted management plan.
There are however, some general measures which may boost up your immune system. Please click on the links below i have searched for you.
These are beautifully written articles, easy to understand.
I hope this clarifies and answers your question.
Wish you good luck.
