Re: prediabetes. is it possible to control diabetes with diet alone?
It is possible, Lorene, but it's more difficult when you can't exercise. You can try low-carbing and see if that helps, but if you find your blood glucose levels starting to creep up, you may have to go on medication. Of course, that may be temporary until you have your knee replacements; sometimes if you can get into a good low-carb and exercise routine, you can then go off medication.
Talk to your doctor about it and see what he/she thinks. This is also going to depend on just how "pre" your pre-diabetes actually is...if you're edging close to the actual diabetes level, you may want to just go with medication until after you've had your knee replacements.
