Initial recovery was challenging and took my intestines a little bit to recover. Yes, some nausea initially but I think that was more the pain medication than surgery. Whipple procedure took my intestines longer to recover and to be able to eat than the distal pancreatectomy/splenectomy. No long term effects from the surgery other than challenges with constipation and/or intestines working like normal. That comes from my intestines being rerouted during the modified Whipple. Linzess has been helpful. Everyone is different and I wish you smooth sailing through the procedure!
