What is the reason for low triglycerides in women

Low triglycerides in women may be caused by long-term dieting, hyperthyroidism, chronic liver disease, malabsorption syndrome, genetic lipid metabolism abnormalities, and other factors.

1. Long term dieting:

Excessive control of diet or long-term insufficient calorie intake can lead to a lack of raw materials for synthesizing triglycerides in the body. When women adopt an extremely low-fat diet to control their weight, insufficient intake of fatty acids directly affects the process of liver synthesis of triglycerides. Physical examinations are common in long-term vegetarian or ketogenic diet groups, often accompanied by symptoms such as weight loss and fatigue.

2. Hyperthyroidism:

Excessive secretion of thyroid hormones can accelerate fat breakdown metabolism, leading to a decrease in serum triglyceride levels. Hyperthyroidism patients often have typical symptoms such as palpitations, excessive sweating, and weight loss. In addition to low triglycerides, laboratory tests also show a decrease in total cholesterol, which needs to be diagnosed through five thyroid function tests.

3. Chronic liver disease:

Liver diseases such as cirrhosis and fatty liver can affect lipoprotein synthesis function. The liver, as the main site of triglyceride synthesis, may experience synthesis disorders when its function is impaired. Such patients often have abnormal liver function indicators such as elevated transaminase and decreased albumin.

4. Malabsorption syndrome:

Intestinal diseases such as Crohn's disease and celiac disease lead to impaired fat absorption. When the small intestinal mucosa is damaged, the fat in the diet cannot be effectively absorbed, resulting in insufficient sources of triglycerides. Patients often experience chronic diarrhea, bloating, and other digestive symptoms, and fecal tests show fat particles.

5. Hereditary lipid metabolism abnormalities:

Familial low beta lipoproteinemia and other genetic diseases can affect lipoprotein assembly. This rare disease is caused by genetic mutations leading to defects in apolipoprotein synthesis, which prevents the normal transport of triglycerides. It can usually be detected from a young age and requires genetic testing for diagnosis.

For mild triglyceride reduction without obvious symptoms, it is recommended to improve by adjusting the diet structure, ensuring daily intake of high-quality fats such as nuts and deep-sea fish, and using unsaturated fatty acid oils such as olive oil for cooking. Patients with combined hyperthyroidism or liver disease should have their blood lipid profile regularly reviewed. It is recommended to engage in moderate intensity aerobic exercise 3-5 times a week to avoid excessive energy consumption caused by fasting exercise. If pregnant women continue to have triglycerides below 0.3mmol/L, it is recommended that the nutrition department consult and evaluate whether medical nutrition intervention is needed.
