In short
Triglycerides are the fat your body stores from surplus calories, and unlike LDL they respond quickly to sugar, alcohol and weight. Here's what the number means, when it becomes a pancreas risk, and what brings it down.

What Triglycerides Are
Triglycerides are the main form in which the body stores fat. After a meal, calories you don't use immediately — especially from sugar, refined starch and alcohol — are converted in the liver into triglycerides and packed into particles (VLDL and chylomicrons) that carry them through the blood to fat tissue.
A fasting level under 150 mg/dL (1.7 mmol/L) is considered normal, 150–199 borderline high, 200–499 high, and 500 or above very high. Because levels swing with recent meals, the test is usually done after a 9–12 hour fast, and a single high reading is normally repeated before anything is decided.
02
Why It Matters
Moderately raised triglycerides are an independent marker of cardiovascular risk and very commonly travel with low HDL, a high waist measurement, raised fasting glucose and raised blood pressure — the metabolic-syndrome cluster that signals insulin resistance. They also point toward fatty liver, which is why a raised SGPT often appears on the same report.
Very high levels — above about 500 mg/dL, and especially above 1000 — carry a separate danger: acute pancreatitis, a painful and sometimes life-threatening inflammation. At that level, lowering triglycerides becomes urgent in its own right rather than a long-term heart-health goal.
03
Common Causes
Excess calories in general, and sugar-sweetened drinks, sweets, white rice and refined flour in particular, are the biggest dietary drivers. Alcohol is a potent one — even moderate regular drinking raises triglycerides in susceptible people. Being overweight, inactivity, and poorly controlled type 2 diabetes all push the number up.
Less obvious contributors include an underactive thyroid, kidney disease, some medicines (certain diuretics, beta-blockers, steroids, oestrogens, isotretinoin and some HIV and antipsychotic drugs), and inherited lipid disorders, which are worth considering when levels are very high or run in the family.
04
What Brings It Down
Triglycerides respond to lifestyle faster and further than LDL does. Cutting added sugar and sweet drinks, swapping refined grains for whole grains and legumes, reducing or stopping alcohol, and losing 5–10% of body weight can each lower levels by 20% or more, and together often normalise a borderline or high result within a few months.
Regular aerobic activity — brisk walking most days — lowers triglycerides and raises HDL. Oily fish twice a week provides omega-3 fats that help modestly; high-dose prescription omega-3 preparations are used for very high levels. When lifestyle change isn't enough, or LDL is also raised, statins are first-line; fibrates are added mainly when the pancreatitis threshold is a concern.
05
Reading It on Your Report
Look at triglycerides alongside HDL, fasting glucose and SGPT. A high triglyceride with low HDL is a stronger warning than either alone, and the ratio of triglycerides to HDL is one of the simplest bedside indicators of insulin resistance. If glucose or HbA1c is also creeping up, the same changes that lower triglycerides will protect against diabetes.
Recheck 6–12 weeks after making changes; the speed of response is a good motivator and confirms whether the cause was mainly diet and alcohol or something that needs a closer look.
