I am a soon to be college runner and I live a very active lifestyle. Ever since I can remember, I have had stomach and abdominal issues. Over the past 2 years, I have gained over 10 lbs while on a very restricted diet and exercise routine. I run about 50 miles a week, lift weights, bike everywhere, and eat a very healthy diet. I have also not had a period since I began running seriously. I am on no form of birth control or hormone treatment currently. Since I began running, I have been consistently experiencing abdominal pain. At different times this pain has been called gas, constipation, ovarian cysts, and kidney stones. Yet, no one ever really fixes the problem. I am desperate to determine what is causing this discomfort and daily trial. My stomach is consistently distended and it appears that I am pregnant. I wouldn't normally complain but it is starting to hurt my running success and my coach wants me to lose weight. thanks
