Often IBS starts in adolescence, and in most cases onset occurs before the age of 40. For most patients, IBS tends to be a chronic condition that flares up from time to time. Many patients can relate the onset of their IBS symptoms to specific important and perhaps upsetting events in their lives, while other patients suffer from IBS that is brought on by routine, everyday stress. Each person is different, and no one can define what stress means to you. Normal bowel habits can vary from one to two times a day to once a week.
Food is another important factor.
Certain foods may bring on symptoms of IBS in some people. If this is the case with you, your doctor will help you determine which foods to avoid. On the other hand, the lack of certain foods may also be an important factor. Generally speaking, high-fiber foods help normalize bowel function. You may never be completely cured of IBS, but fortunately there are some things you can do to help yourself, such as avoiding stressful situations that bring on your symptoms.
