Price: 5 د.ا

Normal Range

Females & Males:

– Less than 150 mg/dL is considered normal.

– 150-199 mg/dL is borderline high.

– 200-499 mg/dL is high.

– 500 mg/dL or higher is very high.

Children:

– Normal range is less than 75-100 mg/dL, depending on age and sex.

Function in the Body

Triglycerides are a type of fat found in your blood. After eating, your body converts calories it doesn’t need into triglycerides, which are stored in your fat cells. Later, hormones release triglycerides for energy between meals. While triglycerides are essential for health, too much can lead to health problems.

Diseases Revealed by the Test

Elevated triglyceride levels can indicate several conditions, including:

– Cardiovascular Disease: High levels of triglycerides can increase the risk of heart disease and stroke.

– Pancreatitis: Extremely high triglyceride levels can lead to inflammation of the pancreas.

– Type 2 Diabetes: High triglycerides are often associated with insulin resistance.

– Metabolic Syndrome: This is a cluster of conditions that occur together, increasing the risk of heart disease, stroke, and type 2 diabetes.

– Hypothyroidism: Underactive thyroid can lead to elevated triglycerides.

– Liver Disease: Fatty liver disease can be associated with high triglycerides.

– Kidney Disease: Reduced kidney function can be linked to elevated triglycerides.

Symptoms

While high triglyceride levels typically don’t cause symptoms, extremely high levels can lead to:

– Abdominal pain (if associated with pancreatitis).

– Fatty deposits under the skin called xanthomas.

– Symptoms of underlying conditions like diabetes or hypothyroidism.

Symptoms of Deficiency and Overdose

Deficiency:

– Triglyceride deficiency is rare and typically occurs in conditions where fat absorption is impaired, such as in malabsorption syndromes or severe malnutrition.

Overdose (Hypertriglyceridemia):

– High triglycerides often present without symptoms but can lead to complications like pancreatitis, characterized by severe abdominal pain.

– If linked to cardiovascular disease, symptoms may include chest pain, shortness of breath, or symptoms of a stroke.

Diagnosis

The triglycerides serum (TRI) test is a blood test usually done as part of a lipid panel during routine health checkups. The test measures the amount of triglycerides in the blood and helps in assessing the risk for heart disease. Fasting for 9-12 hours before the test is often recommended to get accurate results.

Frequently Asked Questions

Q: What can cause elevated triglycerides?

A: Common causes include obesity, poor diet (high in sugars and fats), physical inactivity, smoking, excessive alcohol consumption, certain medical conditions (like diabetes and hypothyroidism), and genetic disorders.

Q: How can I lower my triglyceride levels?

A: Lifestyle changes such as adopting a healthy diet (low in sugars and unhealthy fats), increasing physical activity, losing weight, quitting smoking, reducing alcohol intake, and managing underlying health conditions can help lower triglyceride levels.

Q: Are high triglycerides hereditary?

A: Yes, genetics can play a role in triglyceride levels. Familial hypertriglyceridemia is a genetic disorder that can lead to high triglycerides.

Q: Can medications help manage high triglycerides?

A: Yes, medications like fibrates, niacin, omega-3 fatty acids, and statins can be prescribed to help lower triglyceride levels, especially when lifestyle changes are not enough.

Q: Is fasting necessary for a triglyceride test?

A: Fasting for 9-12 hours before the test is often recommended to get accurate results, as recent meals can temporarily increase triglyceride levels.

Q: What is the connection between triglycerides and heart disease?

A: High triglycerides can contribute to the hardening or thickening of artery walls, increasing the risk of heart disease, stroke, and other cardiovascular problems.

Q: Can children have high triglycerides?

A: Yes, children can have high triglycerides, often due to obesity, poor diet, lack of physical activity, or genetic factors.
