90 yr old woman, with heart problem, depression, anxiety and diabetes which I keep under control with diet (the dr took her off all meds when she moved in with me, while living alone 10 yrs ago she was on meds because she ate wrong), except for some time now she has been midnight eating. She will raid the cookie jar or bread box like crazy. In front of people (anyone) she acts like she just can't eat, like a poor little thing, but she eats a lot when no one is looking. She weighs between 190-195 lbs. She barely eats 1000 calories a day that anyone sees, but eats a lot when no one is looking. I can hear her in the kitchen at night, I even saw her there, she is awake and looking for foods to bring back to her room. I have not approached her because my children think I will scare her and she will fall (again, she's broken bones in other falls). So we let this go, but she is gaining weight and it is affecting her. The dr said she does not take any pill that would cause this (she had the same thing when on sleeping pills). She naps a great deal during the day, and complains she doesn't sleep at night. She barely moves around (using her walker) during the day, she says her legs just won't move. (Although we had the PT here some months ago and she states that her legs are strong.) It seems she just doesn't want to move around during the day, but is quite capable moving at night. I'm worried about what the eating is doing to her, she has gained 20 lbs in 6 months and her blood sugar is too high. The dr wants me to control her carbs and salt intake, but how do I do that when most of what she eats I have nothing to do with? My son-in-law wants me to put a lock on the pantry, is that the only way? It's not that I have all this unhealthy food in my home, but I do have some cookies and chips, stuff she knows she should not be eating. Any suggestions?
