This question tests recognition of the secondary causes of raised triglycerides.
- 1, 2 and 3: wrong, because it drags in hypothyroidism, which mainly raises cholesterol rather than triglycerides.
- 2, 3 and 4: wrong for the same reason - hypothyroidism does not belong on this list.
- 1, 3 and 4: correct. A simple way to remember triglyceride-raising causes is alcohol, obesity/diabetes, azotaemia (renal failure), and thiazides - three of those four match this option exactly.
- 1, 2 and 4: wrong, because although it correctly keeps alcohol and renal failure, it swaps in hypothyroidism instead of thiazide therapy.
Correct answer: 1, 3 and 4 - alcohol excess, thiazide therapy, and chronic renal failure.
