Sugar causes hunger!
Hi Moore, it could be the insulin, since food can be one of the triggers of insulin, which then triggers hunger (so I've read, not an expert!). It could also just be psychological hunger, especially if you've got a big history with sweets. This would not be unusual at any stage post op.
