Hello, since you have thalassemia there is a strong suspicion that your pancreas has been damaged by chronic iron overload. The chelating therapy surely helps but not always (and not completely). If this is your case, then Voligbose might help with postprandial blood glucose but it won t target the source of your problems which is (presumably) insulin deficiency due to pancreatic destruction. If insulin is really missing you should take it regardless of the blood glucose levels to prevent serious complications like ketoacidosis. Voligbose is usually given to type 2 patients who have an almost adequate insulin production. Your doctor is the right person to investigate (by evaluating your history and laboratory tests) whether your diabetes is type 1 or type 2 and modify your treatment accordingly. I hope I ve helped! I ll be glad to ask any further questions you may have. You can contact me again if you d like! Kind Regards!
