What symptoms typically show up when someone has metabolic syndrome or insulin resistance?

Metabolic syndrome itself is usually diagnosed by a cluster of measurable factors rather than symptoms you'd necessarily feel: high blood pressure, high blood sugar, extra weight around the waist, and abnormal cholesterol/triglyceride levels. Insulin resistance specifically can be pretty silent for a long time, though some people notice increased hunger, fatigue after meals, or skin changes like darkened patches (acanthosis nigricans) around the neck or armpits. Because it's often symptom-light, it's usually picked up through routine bloodwork rather than how someone feels day to day.
