This is my first post on here. I saw that this page was recommended on the NHS website. I'm a 29 year old female and back in January I joined a local gym for my first health check my cholesterol was 4.2 which was a good level. At this time my diet was poor and I hadn't been doing any exercise. My BMI has always been healthy though. Fast forward 7 months later and I've been going to the gym 4 times a week and have been working hard to eat a healthy diet I had my next health check and my cholesterol is now at 5.9!!! I really don't understand what has happened and I'm panicking about it now. Does anyone have any similar stories or advice for me? I would really appreciate any help.
