For at least 9 months, I've been having a mix of mostly loose stools and some constipation. Along with that, I sometimes have bloating and frequently have stomach upset. During some weeks, my bloating is so bad that I will go from weighing 120 lbs. to 125 in one week and then the next week, I will go back to weighing 120 lbs, which is my normal weight. I rarely snack in between meals, and do not drink a lot of soda. I often have stomach upset after eating lunch or dinner. I haven't had a menstrual cycle since I had an IUD removed which was at least a year ago. I do not know if this is related. I will appreciate any information you can provide. Thanks!
