Triglyceride Levels: Normal Ranges and Health Risks

Blood triglyceride levels are an important indicator of lipid metabolism. Normally, their concentration in the blood should be low. This means that fats are efficiently processed by the body and do not linger in the bloodstream. If test results show deviations, one should not delay visiting a specialist. A doctor has named the causes of increases and decreases in this indicator.

Normal Triglyceride Levels in Blood

Normal triglyceride levels depend on a person«s sex and age. For boys and girls, they differ until about age 18. The norm for adult men and women is 0.2–1.7 mmol/L.

Moreover, a triglyceride concentration of 1.70–2.25 mmol/L is considered moderately elevated, 2.26–5.65 mmol/L — elevated, and above 5.65 mmol/L — high.

According to statistics from the Gemotest laboratory for 2025, elevated values were detected in 25% of patients. Among men, exceeding the norm is more common — in 30%, while in women — 20%. In children and adolescents up to 17 years old, elevated values are found in 11%, and lowered — in 2.5%. In people over 65 years old, triglycerides above normal were detected in 26%.

Triglycerides Elevated or Lowered — Causes

Elevated triglyceride levels most often indicate a disorder in fat metabolism. This condition can arise against the background of obesity, metabolic syndrome, type 2 diabetes, some endocrine diseases, kidney pathology, autoimmune processes.

«Additionally, an increase in triglycerides can be triggered by taking certain medications — oral estrogens, beta-blockers, steroids, tamoxifen, antiretroviral drugs, atypical antipsychotics,» listed Yekaterina Kashukh, a medical expert at the Gemotest laboratory. «Moreover, high triglyceride concentration is often observed in hereditary dyslipidemias — congenital disorders of fat metabolism.»

Prolonged high concentration of triglycerides increases the risk of developing atherosclerosis, coronary heart disease, heart attack and stroke, as well as acute pancreatitis (even in the absence of other factors).

Low triglyceride levels are rare in practice and can be associated with strict diets, chronic infectious or inflammatory diseases that are accompanied by exhaustion.

According to statistics from the Gemotest laboratory for 2025, elevated values were detected in 25%. Among men, exceeding the norm is more common — in 30%, while in women — in 20%. In children and adolescents up to 17 years old, elevated values are found in 11%, and lowered — in 2.5%. In elderly people over 65 years old, triglycerides above normal were detected in 26%.

«Triglyceride analysis — an important marker of metabolism. It is recommended to take it regularly, especially for people with excess weight, arterial hypertension, diabetes, or hereditary predisposition to heart and vascular diseases,» emphasized the specialist.
