Gastrointestinal symptoms at a glance

Gastrointestinal symptoms involve any upset to your gastrointestinal system—your esophagus, stomach, intestines, rectum, or anus, plus your liver, gallbladder and pancreas. These symptoms include nausea, heartburn, mucositisinflammation and ulceration of the mucous membranes lining the digestive tract, usually as an adverse effect of chemotherapy and radiotherapy treatment for cancer, vomiting, constipation, diarrhea, bloating, gas, and pain. These symptoms can be caused or triggered by cancer, by cancer treatments, by some medications and other medical conditions, and by other symptoms such as anxiety, depression, stress, or pain. 

Managing gastrointestinal symptoms can greatly improve your quality of life and also your overall health by affecting your body weight and your ability to complete cancer treatment.
