If you mother is not insulin
dependent, that means that she has Type 2 diabetes
that mean that she is on another antidiabetic
medication. 280 is a high sugar and if she is taking her medication then probably the dose needs to be adjusted to get better control over her blood sugar levels. It is advisable that you visit your doctor and he will decide further alteration of her medication. Also, she should be on a diabetic diet and I would advise regular exercise which will be of assistance in lowering her blood sugar levels. Other then that she should continue with her COPD
treatment as advised by the doctor.
