Hi, thanks for the query to H.C.M.C.
Type 2 diabetes
usually not require insulin
and this type of diabetes is in obese
Anyway the problem is this that your mother is losing weight due to loss of appetite according to you.
2nd query is that why doctor prescribed "meglu" as she is already on anti diabetic drugs.
As far as concerned about weight loss
that was due to use of byetta.
byetta when given to a patient in type 2 it causes weight loss and that is the part of this treatment to regulate weight of patient.
Same thing happen in your mother case so need not to worry.
Now a days many doctors prefers to use metformin
in combination with byetta and results are very nice .
For loss of appetite you can use many appetizers after consultation with a doctor as many sugar free products are available in market.
Have a good luck for speedy recovery of mother.
