What possible dietary complications could a person develop if they had their pancreas removed?

A. There would be an overproduction of the enzyme trypsin. This would cause an increased rate of protein digestion that could result in the muscle cells being destroyed by the individuals own body. B. They would not produce the pancreatic enzyme trypsin. This would prevent them from breaking down carbohydrates into glucose which could lead to a decrease in the availability of energy in their body. C. They would not produce the enzyme pancreatic amylase. This would prevent them from breaking down proteins into amino acids which could lead to complications in repairing muscle tissue. D. They would not produce the pancreatic enzyme trypsin. This would prevent them from breaking down proteins into amino acids which could lead to complications in repairing muscle tissue.
