Questions about when to begin oral meds

>While visiting my mom today, I checked her blood sugar log. She's checks twice a day, and it runs between 150 and 170 -- consistently, and for quite a while now.<

With only two checks a day (and I assume one of them is fasting), it's hard to know what's really happening. If she starts out at 150, for instance, her post-meal levels could be well into the 200s. Whatever, this is not a good situation. Yes, she's 74, but she could very well have 20+ more years of life ahead of her. With her permission, it'd be nice if you could have a phone conversation with her doc. He probably thinks her A1c is acceptable (if he's not ordering one at least once a year, that's malpractice, IMO), since she might be coming in at 7.0 or so. But her blood sugars are high enough to cause physical hunger, definitely. You're right-- to mask that with anti-anxiety meds sounds more like an effort just to keep her quiet than anything? You suspect dementia; has she been evaluated by an old-age specialist, a gerontologist? Yeah, metformin would seem to make a lot more sense than ativan or something. Can you consult with her doc?
