If there is a blockage of the pancreatic duct
, then pancreatic insufficiency
due to the lack of digestive hormones in the gut might lead to malabsorbtion, as well as malnutrition
. That could lead to fatigue
through different mechanisms (eg. anemia). Severe Vitamin defficiency like in your case can certainly be associated with the aches and pains described.
Nevertheless dear patient, it is of utmost inportance to proceed with further investigations on why there is dilatation and blockage of the pancreatic duct, to reach a specific diagnosis.
Hope it helps.
