Hello,
People suffering from diabetes type 2 basically two problems.
One is less insulin production and other is
insulin resistance.
An ideal anti diabetic medicine is that which reduces cellular insulin sensitivity,reduces excess intestinal glucose absorption,reduces production of glucose from liver,promotes
weight loss and reduces cardiovascular complications.
METFORMIN is the only anti diabetic which does all the above mentioned actions and so it is the most desirable drug for control of diabetes.The maximum dose of METFORMIN which can be given in a day is 2550 mg.
So essentially you are taking too less a dose of metformin.Your doctor is right in increasing he dose of metformin from 250 to 1000 mg a day,as it is one of the safest anti diabetic drug.
As far as
glyburide and
GLICLAZIDE is concerned,both belong to
sulfonylureas class,but since glyburide is long acting and has more chances of developing
hypoglycemia ,doctors generally avoid it .
But since you have been using it for past 8 years,there is no harm in continuing it but the dose may be increased to double.
Gluburide is given once a day as it is long acting.
you may discuss about it with your doctor and abide by her instruction,as she is your well wisher and her judgement should not be doubted.
Thanks
