Clinically relevant maldigestion may occur earlier than overt symptoms of EPI3,11-13

Steatorrhea, the most common clinical manifestation of EPI, may not appear until the disease is advanced and may be absent when patients limit fat intake to avoid symptoms.

There may be significant maldigestion and malabsorption in patients without the classic clinical sign of steatorrhea.
