Janette,
Welcome to thalpal! Thalassemia minor can affect individuals very differently. Some people are minimally affected, and may not have any symptoms at all. Meanwhile, others can have many symptoms including fatigue, dizziness, weakness and others.
Symptoms of thalassemia minor respond very well to a balanced diet, various supplements (listed in the nutrition and supplement section of the forum), and exercise. If you are experiencing symptoms, if you share them with us we can help you find the proper diet and supplements to hopefully alleviate or at least decrease your symptoms.
Once again welcome to thalpal - we are happy to have you on board!!
Sharmin
