My daughter is 20 years old, trim and fit.  She has high triglicerides (sp?).  She had been experiencing increasing frequent occurrences of a racing hear and chest pain which lasts for days.  They are not always coincident.  She had an EKG and they said it was fine.  What could this be?
Hello! Thank you for asking on Chat Doctor! I understand your concern, and would explain that her symptoms may be related to a metabolic disorder like hyperthyroidism, which is a dysfunction of the thyroid gland. High triglycerides can also be related with pancreatitis, and a hormonal imbalance (like ovarian cysts). So a comprehensive differential diagnosis should be done to establish the possible cause of her symptomatology. I would recommend consulting with her GP for a careful physical examination, a chest x-ray, and abdominal ultrasound and some blood lab tests
