Hi Krissi,
Thalassemia minor may or may not be associated with feeling sick more often. Being anemic can certainly cause you to become more fatigued and possibly more prone to getting infections. The best way to deal with this is to ensure that you are taking proper vitamins and supplements. Under the vitamins and supplements section we have listed many vitamins that thal minors may find helpful. Be sure to avoid iron in vitamin supplements and iron is not suitable for thal minors unless if specific iron testing indicates an actual deficiency in iron. Vitamin C should help you in strengthening your immune system, and even more so vitamin D can help you with your immune system.
You can ask your doctor for a test to determine if you have a vitamin D deficiency. Having a vitamin D deficiency causes you to have more colds and leaves you fatigued.
Best of luck and please feel free to ask any other questions that you may have,
Sharmin
