Is he suffered previously with that problem??
Yes it is possible that pancreatitis patients may develop
loose motion, due to insufficient level if pancreatic
lipase or
amylase etc.
Until examination is done it is difficult to say what it is.
Please check his serum amylase or lipase , get
ultrasound abdomen.
Avoid fatty food, eat low quantity food with increased frequency.

smoking and caffeine drinks.
If symptoms not improved please consult your gastroentrologist he will examine and treat you accordingly.
