Get tested: Repeated infections in a young person suggests a weakness in the immune system. Some immunodeficiencies are genetic & show up in early adulthood. Others may be acquired such as hiv. A specialist needs to sort this out.Other diseases can mimic infection such as autoimmune disease. This requires special testing. Always maximize your general health with proper rest, nutrition & exercise.

See an allergist: People with allergies have constant inflammation in the nose and sinuses. Nonallergic people can typically handle the inflammation of a viral infection without much trouble; but in an allergic person, adding the viral inflammation on top of the underlying allergic inflammation makes perfect conditions for bacteria to grow. Treating the underlying allergic inflammation usually helps immensely.

Further Inquiry: Recurrently ill can be a sign of immune defiency or allergy. There also can be other factors at play such as ciliary dyskenisia or gastroesophageal reflux. It would be worth discussing with your doctor and considering a referral for allergy testing as well as evaluation of your immune system if these are truly documented bacterial infections.
