Thank you for the query.
I would want to know the age of your mother in law. I would also like to enquire the duration of her
diabetes, her HbAic levels and the dose of glimeperide that she is taking.
Your husband is right in one way, with a blood sugar as low as 40mg%,
antidiabetic medications should not be given. A sugar level of 40mg%, indicates
hypoglycemia, which is not desirable in a diabetic subject. Infact when she is having low sugar level, she needs to be given
glucose water. I would request you to maintain a record of her blood sugar (either by self monitoring of blood glucose by a glucometer or by laboratory investigations of Fasting blood sugar and Post prandial blood sugar-2hrs). The dose of her anti-diabetic medications may need to be adjusted , if she keeps on having hypoglycemia (sugar levels less than 60-70mg%). You need to keep a close watch to see whether she is having any diet-exercise-drug imbalance.
It is suggested that she should undergo a renal parameter testing (Serum urea,
creatinine and urine for spot ACR). Please consult her physician with the investigation reports, because as I have mentioned, she may need dose adjustment of her medications.
Hope this helps you out.
