Excerpt from the article: The natural approach to lowering triglycerides
"Although over consumption of carbohydrates and/or alcohol are the most common causes of high triglycerides, other contributing factors include:
Prolonged stress
Excessive caffeine (more than 4 cups of coffee daily)
Cigarette smoking
Hypothyroidism (underactive thyroid)
Some pharmaceuticals such as Prednisone (corticosteroid), hormone replacement therapy, antifungals, Accutane (acne treatment), Remeron (antidepressant) and several liver and kidney drugs."
