Have they done a diabetes test on him?
If there is another hospital in your town, you may want to go to your family doc and see if he/she endorses the hospital your hubby is in or if he/she would want your hubby in a different hospital. There are many hospitals that have a specialty like cardiac or pulmanary care as well as womens hospitals that concentrate on birthing medicine.
There is a serious problem here and they need to be agresssive to fix this.
Also, make sure that his pain level is managed so he is getting relief! There have been hundreds of studies done on the coralation between proper pain management and speedy recovery!!! If he complains of pain, he needs to be ringing the nurse and keeping her busy with him until they pay attention and help him with his pain! Pancreatitus is super painful and very deadly, please be hard on the staff to make them treat him relentlessly!!
