People with thalassemia are generally not allowed to donate blood.
Thalassemia is a hereditary hemolytic anemia caused by defective bead protein gene. If you donate blood, you may aggravate the symptoms of anemia, such as pale skin and mucous membranes, dizziness and tinnitus, nausea and vomiting, and in severe cases, palpitation and shortness of breath and shock may also occur.
And because thalassemia patients have one or several kinds of reduced synthesis or inability to synthesize the peptide chain of beads protein, which can cause the structural abnormality of hemoglobin. Therefore, people with thalassemia generally cannot donate blood.
Thalassemia is a hereditary disease, which is difficult to be cured at present, but active treatment can lead to long-term survival. Patients should have a reasonable work schedule, ensure sufficient sleep, avoid overwork, and actively seek medical treatment.
