Pancreas Pancreatic Insufficiency & Liposoluble Vitamin Deficiency

I know this is a stupid question, but is it because the steatorrhea causes malabsorption of liposoluble vitamins? And if this is the case, why? Thanks. I'm reading Biochemistry and I came across this roadblock. Don't laugh!

because you have pancreatic deficiency, you cant break down the fats in your duodenum and hence that are poo'ed out (steatorrhea). Since the fats arent broken down and absorbed, fat-soluble vitamins and also not broken down and absorbed. so you have a deficiency of fat-soluble vitamins.

Pancreatic Enzymes that are responsible for lipid digestion are not functioning

These include :

1) Lipase -> Triglyceride

2) Cholesterol Ester Hydrolase -> Cholesterol Esters

3) Phospholipase A2 -> Phospholipids

Pancreatic Insufficiency & Liposoluble Vitamin Deficiency causes steatorrhea and malabsorption. Not the other way around (like it was phrased in your question ). Steatorrhea is a sign of malabsorption of lipids.
