Hello. I'm sorry your mother-in-law is having so many problems. Her shortness of breath
is undoubtedly due to her left ventricular failure, and her heart failure
is probably the combined result of her poorly controlled diabetes
and high blood pressure
. It sounds like these problems were controlled while your mother-in-law was in the hospital, but since her discharge she appears to have slipped back into her old pattern. You didn't mention whether her diabetes was controlled with insulin
while she was hospitalized, but it does sound like she needs it now, at least temporarily. During illnesses, some diabetics cannot control their blood glucose
with oral medications alone. In addition, most physicians will prescribe insulin when a diabetic patient's blood glucose is consistently above 250, as this could indicate beta-cell failure. (Beta-cells are the specialized cells in your pancreas
that produce insulin. In most type 2 diabetics, the beta-cells eventually "wear out" and no longer make enough insulin to keep their blood glucose under control. At this point, they need to begin using insulin.)
Your mother-in-law should contact her doctor again. If she isn't already monitoring her own blood glucose levels, she'll need to learn how to do that if the doctor decides to prescribe insulin. She should also be checking her own blood pressure on a regular basis.
I hope that anwers your question, and I hope things go well for your mother-in-law.
