The most common symptoms of<unk> is are severe upper abdominal or left upper quadrant burning pain radiating to the back,<unk> a, and vomiting that is worse with eating. The physical examination will vary depending on severity and presence of internal bleeding. Blood pressure may be elevated by pain or decreased by dehydration or bleeding. Heart and respiratory rates are often elevated. The abdomen is usually tender but to a lesser degree than the pain itself. As is common in abdominal disease, bowel sounds may be reduced from reflex bowel paralysis. Fever or jaundice may be present. Chronic<unk> is can lead to diabetes or<unk>  cancer. Unexplained weight loss may occur from a lack of<unk>  enzymes hindering digestion. Complications Early complications include shock, infection, systemic inflammatory response syndrome, low blood calcium, high blood glucose, and dehydration. Blood loss, dehydration, and fluid leaking into the abdominal cavity (ascites) can lead to kidney failure. Respiratory complications are often severe. Pleural effusion is usually present. Shallow breathing from pain can lead to lung collapse.<unk>  enzymes may attack the lungs,<unk> ng inflammation. Severe inflammation can lead to intra-abdominal hypertension and abdominal compartment syndrome, further impairing renal and respiratory function and potentially requiring management with an open abdomen to relieve the pressure. Late complications include recurrent<unk> is and the development of<unk>  pseudocysts—collections of<unk>  secretions that have been walled off by scar tissue. These may<unk>  pain, become infected, rupture and bleed, block the bile duct and<unk>  jaundice, or migrate around the abdomen. Acute necrotizing<unk> is can lead to a<unk>  abscess, a collection of pus<unk> d by necrosis, liquefaction, and infection. This happens in approximately 3% of<unk> s or almost 60% of<unk> s involving more than two pseudocysts and gas in the pancreas.
