As discussed, high cholesterol may not show any signs. However, if left untreated for long, it can lead to a condition called atherosclerosis, wherein your arteries become clogged with fatty substances called plaques.

This can in turn block your arteries and stop the blood flow to your legs, giving light to another condition called peripheral arterial disease (PAD).

According to the UK’s National Health Services (NHS), PAD can cause a smelly warning sign, which is associated with critical limb ischaemia (CLI) – an “extremely serious” complication that can be difficult to treat.
