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."
I'd suggest that this question is best answered by a health professional who understands your husband's condition.
