Irritable Bowl Syndrome is the result of an overactive or lazy colon. If your stools are watery, it is overactive. If you are constipated, your bowl is lazy. The best way to deal with this, is to eat a lot of fibre and wholegrain, this will absorb water, and stimulate your bowl - it is a corrective measure. Also stay away from yeast products, like white bread. Yeast products causes IBS-patients to blow up and have windy flatulence. It is a good idea to clean your stomach out once a month with a laxative, and start afresh. It differs from person to person what food to avoid. Take note of what you have eaten the previous day, and compare it to your IBS symptoms the next day. This way you will learn to listen to your body, and avoid food that your body don't like.
