High Triglycerides Level. Normal range.

Dear Sira I got Covid 6 months back and was isolated hone since it was mild. After recovery my doctor suggested to go with Lipid test and got results and all are within normal range except triglycerides which was 291. Then doctor suggested me to take Fibral 200mg for one month and then tested again after 2 months. And results are almost same as previous (report attached) Total Chelestrol -208 Triglycerides-269 HDL-38 LDL- 116 Pls suggest it is risky or should I go with any other medicine. My age is 36, Height 5 feet 8 inches and weight is 77kgs. My doc said reduce weight. Pls advise your understanding how risky this figure and what are precautions to be taken to correct above figures within normal range. Thanks in advance.
