Answer: C - dehydration
One of the hallmark features of pancreatitis is dehydration. Pancreatitis, an inflammation of the pancreas, can lead to several systemic symptoms contributing to dehydration. The inflammation often causes severe abdominal pain, leading to decreased oral intake, including fluids. Vomiting and diarrhea, which are common symptoms, further exacerbate fluid loss. Additionally, the inflammatory process can disrupt the average fluid balance in the body, leading to fluid sequestration in the abdominal cavity, further depleting the body's accessible fluid reserves. The combination of reduced intake and increased loss of fluids makes dehydration a significant concern in managing pancreatitis. Prompt recognition and treatment of dehydration are crucial to prevent complications and support recovery.
