Weird green mucous in stool, no odor, no pain, have had yellow and clear but not green, should i be concerned? stomach hurts occasionally after eating

Mucus: Mucus in stool occurs with colitis or irritable bowel syndrome. Abdominal discomfort after a meal, and especially if associated with loose stools, is another symptom seen in irritable bowel syndrome. Determine what foods bother you. Avoid harsh roughage in your diet. If symptoms persist or worsen, see your physician or a gastroenterologist for evaluation and treatment.
