Lipid Profile: How to Prepare, and What Your Cholesterol Numbers Mean

2026-07-05 · 2 min read

Heart disease arrives a decade earlier in South Asians than in most other populations — which makes the lipid profile one of the most important tests for anyone over 30 in Hyderabad. Here's how to do it right and read it right.

First: the fasting question

Traditionally the lipid profile needs 10–12 hours of fasting — dinner by 9 PM, sample by 8–9 AM, water freely allowed. Fasting mainly affects triglycerides, which spike after meals. If your doctor asked for a fasting lipid profile, book a morning slot or a morning home collection; it's the most comfortable way to do it.

The four numbers

Total cholesterol is the headline figure, but it's the least useful alone — it mixes the good and the bad.

LDL ("bad") cholesterol deposits in artery walls. This is the number doctors treat. Under 100 mg/dL is optimal for most people; those with diabetes or prior heart problems get stricter targets.

HDL ("good") cholesterol carries fat away from arteries. Higher is better — above 40 mg/dL for men, 50 for women. Exercise is the most reliable way to raise it.

Triglycerides reflect diet, alcohol, and how your body handles sugar. Under 150 mg/dL is desirable; very high levels also stress the pancreas.

Why "normal-looking" people should still test

High cholesterol has no symptoms — the first sign is too often a heart event. Slim people, young people, vegetarians: all can have high LDL, because genetics contributes as much as diet. A lipid profile every year (or every 6 months if already elevated) is basic maintenance, like servicing a bike.

What if my numbers are high?

Not a sentence — a signal. Diet changes, 30 minutes of brisk walking, and (if your doctor prescribes them) statins bring LDL down predictably. Retest after about 3 months of changes to see the effect.
