I am so sorry to hear of the health issues you and your wife have been dealing with over the past year. I am not an MD, so I can't answer your questions regarding if something was missed by the health care professionals that your wife saw. I can tell you that you may never know the "why's" of what has happened to her, and that's OK. I hope that she is under the care of an endocrinologist (diabetes specialist). That is who may have the answers to some of your questions. The important thing is that you are there for her and support her through all of it (and you writing this e-mail tells me that you already do!). I myself have had medical mishaps occur and it is truly counterproductive to dwell on things that we may never know the answers to. It is true that people with diabetes are at higher risk for vascular abnormalities along with other types of complications. Maintaining optimal blood glucose control is extremely important in avoiding the major complications of diabetes. Stroke and diabetic retinopathy are some of those complications. I know what it's like to care for someone with diabetes as I am the mom of a 16 year old who was diagnosed at the age of 21 months. It is not easy, but making healthy lifestyle choices with food and exercise may prevent further complications, so I hope that you continue to support her in everything that she goes through. She is very lucky to have someone who cares so much. I wish you and her the best in her recovery process.
