Morphology

lactase + deficiency

Given knowledge of 'lactase' (the enzyme that breaks down lactose) and 'deficiency' (a lack or insufficient amount), a B1 learner can directly infer that 'lactase deficiency' means having too little lactase. The compound follows a regular medical pattern ('X deficiency') that is compositional and cross-linguistically common, so the meaning is predictable from the parts.

Etymology

Lactase deficiency comes from lactase, the body 'enzyme' that breaks the milk sugar 'lactose', and deficiency, meaning 'not having enough'. So lactase deficiency literally means not having enough lactase, which explains why people with it cannot digest milk and often feel uncomfortable after eating dairy.
