Question: I work 8 hour shifts, but get forced to work 16 hours shifts through the night time hours a few times a week. I recently had blood work done because I was having symptoms that alarmed me. They seemed to be getting progressively worse as I work these longer hours. Some of my symptoms include a faster than normal resting heart rate while trying to fall asleep (95bpm) after a shift. Others include severe trembling, jaw pains on both sides, and overall full headaches at times. About 10 months ago I was in ER with similar symptoms when I was working longer hours. They ran a chest xrays, troponin tests, and EKG's and said all looked fine. My recent bloodwork numbers are as follows: total cholesterol-169, triglicerides-123, HDL- 43, LDL- 101. I realize the LDL and HDL numbers are close to being out of range which has alarmed me. I was eating poorly and drinking soda at times. In the last few weeks I gave up fast food and soda and started eating berries, oatmeal, vegetables, and taking fish oil pills daily. Any ideas on stress being a factor or could it be cholesterol related due to semi bad HDL and LDL numbers? Thank you for the help.
