You are not that underweight, and you should be able to menstruate again once you make some lifestyle changes. I had a brief encounter with anorexia/bulimia in college and ammenorhea, so I understand where you're coming from. Making the changes listed below, and gaining as little as 3-5 lbs should help your body regain its cycle. Since you've struggled with anorexia, you can focus your obsessive/compulsive tendencies on healthy eating and some sort of outlet/hobby that makes you healthy.
1) balanced diet - focus on veggies, fruit, PROTEIN and FAT which are essential for hormone production (organic/non-processed). you don't need to eat many more calories if any, they just need to come from healthy sources. I know this can be hard when you have an eating disorder but your body really needs nutrition in order to ovulate/menstruate. irregular eating patterns will also mess with your hormones (eg binging, purging, and regular fasting) 2) sleep - you need to get at least 7 hours of sleep a night for normal hormone production and to regulate stress hormones. in addition, sleep is really important for memory and learning. 3) minimize high intensity/long duration workouts - excessive exercise can put a lot of stress on the body and interfere with your LH surge. incorporate swimming, walking, pilates and yoga to reduce stress and boost mood. 4) find some other activity to focus on other than food/school/exercise - finding a hobby, job or activity that allows you to socialize and be happy can do wonders for your health 5) avoid taking birth control or any artificial hormones - these will prevent you from becoming in touch with your feminine self and regain back your natural cycle 6) flirt with boys - engaging with boys/men may awaken your sexual energy and help you regain your cycle. women that have sex regularly also have more regular cycles.View Thread
