Low triglycerides (39)


Dear Dr.
Ke: My triglyceride level is low (39), high-density lipoprotein (HDL) is 66, low-density lipoprotein (LDL) is 116, and total cholesterol is 185.
My height is 174 cm and weight is 67 kg.
I have been following a "DASH diet" for two years and exercise regularly 2 to 4 times a week (1 to 2 hours each session), playing basketball and running.
My blood pressure has decreased from 150/100 to 135/90.
I eat very lightly, but I consume flaxseed oil and nuts daily, and I eat at least one serving of meat every day, often including fish.
Am I not getting enough oil in my diet? What symptoms can low triglyceride levels (39) cause in the body?

Dr. Ke Taiyuan reply Internal Medicine


Low triglycerides are related to diet and serve as one of the energy sources for the body after metabolism.
Your total cholesterol is not very low, and your high-density lipoprotein (HDL) is also not low.
Your BMI is within the normal range, so your nutritional status should be fine.
There is no need to worry about low triglyceride levels.

More Info


Low triglyceride levels, such as the reported value of 39 mg/dL, can raise questions about potential health implications, especially when considered alongside other lipid profile components like high-density lipoprotein (HDL) and low-density lipoprotein (LDL) cholesterol. In general, triglycerides are a type of fat (lipid) found in your blood, and they serve as a significant energy source for the body. They are derived from the foods we eat, particularly fats and carbohydrates, and are also produced by the liver.


Health Implications of Low Triglycerides
1. Nutritional Status: Low triglyceride levels can sometimes indicate a lack of sufficient caloric intake or malnutrition. However, in your case, given the balanced diet and regular exercise, this is less likely. Your diet, which includes flaxseed oil, nuts, and regular protein sources like meat and fish, suggests that you are consuming healthy fats and proteins.

2. Metabolic Health: Low triglyceride levels are often associated with a lower risk of cardiovascular diseases. They can indicate good metabolic health, particularly when combined with a healthy lifestyle, as you have described. Your HDL level of 66 mg/dL is also favorable, as higher levels of HDL cholesterol are linked to a reduced risk of heart disease.

3. Potential Symptoms: While low triglycerides are generally not a cause for concern, extremely low levels can sometimes be associated with certain health issues. These may include:
- Hormonal Imbalances: Very low triglycerides can affect hormone production, particularly sex hormones, which may lead to symptoms such as fatigue or changes in mood.

- Nutrient Deficiencies: If triglycerides are low due to inadequate dietary fat intake, it could lead to deficiencies in fat-soluble vitamins (A, D, E, K), which can have various health implications.

- Pancreatitis: Although high triglycerides are a known risk factor for pancreatitis, very low levels are not typically associated with this condition. However, it’s essential to maintain a balanced level.


Dietary Considerations
Your current diet appears to be well-structured, focusing on healthy fats and regular physical activity. However, if you are concerned about your triglyceride levels being too low, consider the following dietary adjustments:
- Increase Healthy Fats: Incorporate more sources of healthy fats, such as avocados, olive oil, and fatty fish like salmon. These can help ensure that you are getting enough energy and essential fatty acids.

- Monitor Caloric Intake: Ensure that you are consuming enough calories to meet your energy needs, especially given your active lifestyle. If you are exercising regularly, your caloric expenditure may be high, necessitating a higher intake.

- Consult a Nutritionist: If you have ongoing concerns about your triglyceride levels or overall dietary balance, consulting with a registered dietitian or nutritionist can provide personalized guidance tailored to your health goals.


Conclusion
In summary, while low triglyceride levels can sometimes raise concerns, in your case, they appear to be a reflection of a healthy lifestyle and diet. As long as you are feeling well and maintaining a balanced diet, there is likely no need for alarm. However, if you experience any unusual symptoms or have further concerns, it is advisable to consult with a healthcare professional for a comprehensive evaluation. Regular monitoring of your lipid profile and overall health will help ensure that you remain on track with your health goals.
