Hello, my 14 yr old daughter has hemoglobin H. It is apparently minor since she lives a normal life. We do not have a special diet or take any sort of supplements or vitamins. She swims about 2 hrs a day (swim team) and is fairly good (one of the best in her team). My question: How will starting her menstrual cycle affect her? If doctors generally advise normal women to take iron or eat more meat during the women s cycle, because of low iron or blood, how will a period affect someone with hemoglobin H? Thank you.
