Hi Thanks for writing to Health care magic Chronic pancreatitis is a chronic inflammation of pancreas. Due to repeated insults on pancreas by toxic substances like alcohol, oxidant stress, autoimmune and other insults pancreas develops chronic inflammatory changes and fibrous tissue in it. This pancreas looses its exocrine i.e digestive function as well as its endocrine i.e insulin secreting function. The ultrasound abdomen shows heterogenous pancreas in chronic pancreatitis. One important condition to be differentiated in this case is a pancreatic cancer. Consult ur treating doctor to find the cause and proper treatment at the earliest. Thanks and regards
