Hello..my husband had pancreatitis once and he ended up in the hospital in severe pain. The problem was that he had diabetes and didnt know it. His blood sugars were way out if whack and so was his cholesterol. The cholestel problem was so bad that when they did his blood samples, they say he had blobs of fat in his blood...just like when you cook a turkey and the fat floats around and you have to strain it before you make gravy. They had never seen such high triglycerides!
Anyway, the fat plugged up his pancreatic duct, which caused his pancreas to become swollen and which caused excrutiating pain. He was in hospital eight days on painkillers and fluids while they waited for the blockage to clear and swelling to go away. He has been fine since and manages his diabetes.
My understanding is that pancreatitis is very painful, so if you had it, you would probably be in the hospital. My husband didnt throw up when he had pancreatitis. He didnt feel sick...maybe bloated, but it was pain mostly
