Explain why pancreatitis patient's stool is foul smelling and oily?

Pancreatitis is a condition in which the pancreas becomes inflamed, leading to a disruption in the production of digestive enzymes. These enzymes are responsible for breaking down fats, proteins, and carbohydrates in the food we eat. When the pancreas is not functioning properly, the body is unable to properly digest fats, leading to oily and foul-smelling stools.

Additionally, the lack of digestive enzymes can also lead to malabsorption of nutrients, which can further contribute to the foul smell of the stool. The undigested fats can also cause the stool to appear greasy or oily.

Overall, the foul-smelling and oily stools in pancreatitis patients are a result of the impaired digestion and absorption of fats due to the dysfunction of the pancreas.
