What is she eating in the meantime..obviously we can't recommend from here with this complicated a case, but I would think that anything that would cause blood sugar to rise in a regular diabetic prone person..fruits, juices, pop, starches of any kind...would probably make it worse...green vegetables, healthy fats and meats would lower it..but again, her situation is so complicated that ordinary situations might not apply or her eating may be so restricted that she has to eat the bs raising foods and take the insulin...it is unfortunate that she will probably never find a doctor that could tell her the best plan..but that is almost universal.
