Why am I always constipated? Usually I don't have many bowel movements.but I haven't had one in over a week! I feel so heavy and grossAnd my stomach is so bloatedThis has happened before and I took some laxatives, but I don't want to do it anymoreIsn't there something I can do to avoid constipation all together?I also lead a pretty healthy lifestyleThis week for example I did a TON of walking, so it shouldn't be due to lack of exerciseI also drink a lot of water (I only drink water and coffee), eat fiber (usually i have bread and yesterday i had fiber 1) and I also eat a lot of vegetablesHELP!
