    ### Response:
    Intestinal pseudo-obstruction is a digestive disorder in which the intestinal walls are unable to contract normally (called hypomotility); the condition resembles a true obstruction, but no actual blockage exists. Signs and symptoms may include abdominal pain; vomiting; diarrhea; constipation; malabsorption of nutrients leading to weight loss and/or failure to thrive; and other symptoms.
