Several factors contribute to GI issues in cancer patients:
Tumor location: Tumors in the GI tract can cause direct obstruction or bleeding. Treatment side effects: Chemotherapy and radiation can damage the lining of the GI tract, leading to symptoms like nausea, vomiting, and diarrhea. Medications: Painkillers and other drugs used in cancer treatment can cause constipation or other GI disturbances. Nutritional deficiencies: Cancer and its treatments can affect nutrient absorption, leading to malnutrition and associated GI symptoms.
