High triglyceride levels usually accompany low HDL (good) cholesterol and often travel with tendencies toward high blood pressure and central (abdominal) obesity. These are the markers of metabolic syndrome and insulin resistance, very common disorders that increase risks of heart and adult-onset diabetes. You should definitely begin a more healthy diet, and you will find this will improve your health in more than one aspect. Also, you should begin taking omega-3 oil supplements, which come as fish oil. You will want to get regular exercise; lose weight if you're overweight; reduce the amount of saturated fats and trans fat in your diet; and cut back on alcohol, avoiding beer especially. (Even small amounts of alcohol can elevate triglyceride levels.)
I'm not sure if the high triglycerides are the cause or have any impact on your current symptoms, however it is always worth a try to lower your cholesterol since it is a healthy idea anyway.
