She's on metformin for the diabetes, an anti-depressant, blood pressure med, baby aspirin, and vitamins, as well as oxygen almost around the clock. When not eating she's in bed. Her diet's pretty good thanks to a high-protein, sugar-free shake mix, but my father gives in to her demands for goodies such as fruit, bread, & potato chips. Don't know if that's enough to create cravings; her fasting blood sugar level is between 136 and 160 lately. She forgets what just happened and often argues after a full meal that no one gave her anything to eat. Could it be part of the dementia - has anyone else experienced this?
