Triglycerides are a form of lipid (fat) present in the blood. They are the most prevalent form of fat in the body and are mostly produced from dietary fats and carbs. Triglycerides provide energy to the body, however having excessive amounts of triglycerides might indicate an underlying health problem.

Several causes can contribute to low triglyceride levels, including:

• Underlying medical issues: Triglyceride levels can be reduced by illnesses such as starvation, hyperthyroidism (overactive thyroid), liver disease, and some hereditary abnormalities.
• Medications: Triglyceride levels can be reduced as a side effect of some medications, such as cholesterol-lowering pharmaceuticals like statins, fibrates, or omega-3 fatty acid supplements.
• Diet and lifestyle: A low-fat and carbohydrate diet, as well as a restrictive diet, such as fasting or malnutrition, can result in low triglyceride levels.
• Genetic factors: Some people have a genetic disorder called familial hypobetalipoproteinemia, which can cause low triglyceride levels.

High triglyceride levels can signify numerous issues:

• A diet heavy in refined carbs, sweets, and bad fats can contribute to elevated triglyceride levels.
• Obesity: Being overweight or obese is frequently associated with higher triglyceride levels.
• Sedentary lifestyle: A sedentary lifestyle and a lack of physical activity might contribute to elevated triglyceride levels.
• High triglycerides are frequently found in conjunction with other disorders such as abdominal obesity, high blood pressure, high blood sugar, and low levels of high-density lipoprotein (HDL) cholesterol.
• High triglyceride levels can be caused by hereditary causes such as familial hypertriglyceridemia in some situations.
• Diabetes, renal illness, liver disease, and an under-active thyroid (hypothyroidism) are among medical problems that can lead to increased triglycerides.
