Hi, I had gone through your question and understand your concerns. The normal range for high triglycerides is under 150mg/dl and cholesterol is under 180mg/dl for your age. You should be worried but not too much. Your cholesterol is not that high to be very worried. You may easily get back to normal range. I see similar cases amongst young people who visit my clinic. In the first meeting, I advise my patients to go on lifestyle modifications for three months. I retest them again after three months and if they continue to be in high range then I advise them to take statin group of medicines like Atorvastatin and Pravastatin. You can discuss this with your treating Doctor. For the next 2-3 months, try to follow the following guidelines. Then get your cholesterol checked again. High fiber diet, green leafy vegetables, fruit. Cut down the processed food. White bread, doughnuts, white sugar, pizza should be completely avoided. A 40 minute physical activity every day like morning walk, evening walk or a visit to the gym or swimming pool. Start on these changes and get back to me in 2 to 3 months. Wish you good health.
