My brother- in- law, who is 72 has been recently diagnozed with beta-thalassemia.  He is also diabetic and has thyroid problem.  Presently, his haemoglobin level is at 8.  He feels weak and his appetite is poor.  He is in Mumbai.  His family doctor advised him to visit CMC Vellore, but that is quite far.  For him it may be difficult to undertake such a trip.  What should be the next step?  Is there any good specialist in Mumbai whom he can consult?  As we were made to understand, he will need blood transfusions?  When he will need it?  And which is the best place to undrgo the procedure? (In Mumbai)

Summarized question: When is blood transfusion needed for beta thalassemia?
