People with thalassemia make less hemoglobin and have fewer circulating red blood cells than normal, which results in mild or severe microcytic anemia. Thalassemia can cause complications, including iron overload, bone deformities, and cardiovascular illness.

Condition details

People with thalassemia can get an overload of iron in their bodies, either from the disease itself or from frequent blood transfusions. Too much iron can result in damage to the heart, liver, and endocrine system, which includes glands that produce hormones that regulate processes throughout the body. The damage is characterized by excessive deposits of iron. Without adequate iron chelation therapy, almost all patients with beta-thalassemia accumulate potentially fatal iron levels. If both parents are carriers of the thalassemia gene there is a 1 in 4 chance of a child acquiring Thalassemia. Carriers of the gene display no symptoms except anaemia or borderline anaemia. It is therefore important to consider genetic counselling prior to starting a family if both parents originate from areas where Thalassemia is prevalent (Mediterranean countries/usa/ north Africa/middle east).
