A person can interpret the symptoms of spastic colon, or irritable bowel syndrome, by keeping a diary of the foods he eats and when he experiences symptoms. After a couple weeks, he can compare the foods and symptoms to determine which foods trigger the symptoms, recommends Healthline.
The food diary needs to include all of the foods he eats, when he eats, how he feels when he eats and the occurrence and intensity of any symptoms. A small notebook or a note app on a smartphone work for this, as long as the person can keep track of the foods and symptoms no matter where he is eating or experiences symptoms. While some symptoms appear after a few hours, others may take a few days. The pattern that forms after two or more weeks of tracking food consumption and symptoms should help him interpret which foods trigger his symptoms, according to Healthline.
Foods that often cause symptoms in people with spastic colon include fried or fatty foods, caffeinated drinks, artificial sweeteners, high-fructose corn syrup, candy, chocolate and alcohol. Others include dairy products, broccoli, beans, cabbage and some fruits. Keeping a food diary is useful because not everyone with IBS has a reaction to these foods, or they may experience a reaction to other foods, explains Healthline.
