Hi I just read your concerns and I also feel that there is a connection between steroids and diabetes. I have been type 1 diabetic for the last twenty years and there is no hisstory of diabeties in my family. When I was 12 I had leukaemia and subsequent radiotherapy and chemotherapy. I feel that the drugs used to cure my cancer caused damage to my pancreas and the cells that produce insulin. Has anyone else out there become diabetic after chemotherapy ?
Could it be that your suspicions are reversed and that the diabetes was caused by the usual autoimmune malfunction, and that the same autoimmune system malfunction was the cause of the asthma attack? Has your child been tested for the presence of antibodies that show that the immune system is attacking the pancreas? If these antibodies are present (a simple blood test is used to check for them), then it is very likely that the immune system had been attacking the pancreas for a period of months or even years, and that the same autoimmune over-activity caused the allergy symptoms that lead to the asthma attack. Many type 1 diabetics also suffer from allergies or other autoimmune problems such as thyroid malfunctions or celiac disease. It is possible that the steroids had nothing to do wtih the problem, but that the immune system caused both problems. Type 1 diabetes is also sometimes called autoimmune diabetes, and it tends to pop up unexpectedly without other type 1 diabetes being present in the families. Some think that this is because one damaged gene tends to be inherited from each parent, and the two damaged genes produce the autoimmune system problem that sets up the attack on the pancreas.
I am not a physician, but the mom of a type 1 diabetic who also has asthma. I can tell you from personal experience, the steroids that are given to asthmatics do usually raise the blood sugars. Some people it can lower, but for the most part and steroid will raise bloods sugars. You would be surprised how different drugs can affect blood sugars. Whenever we give our daughter her asthma meds we increase her I insulin doses a little to compensate.
I have not found any true correlation that proves that steroids cause diabetes. I have tried because, I have felt the same as you do now as our daughter had a steroidal medication about 4 weeks prior to her diagnosis, with a bad asthma attack and a high fever. When she was diagnosed she didi not have any of the classic symptoms. I was told that it was coincidental . I searched and could not find any proof that one caused the other.
