Abstract
Acute and chronic gastrointestinal problems are common in the setting of excessive alcohol use, and excessive alcohol use is associated with injury to all parts of the gastrointestinal tract. There is mounting evidence of gastrointestinal injury and increased cancer risk even from moderate alcohol consumption. The major causes of alcohol‐related morbidity and mortality within the gastrointestinal system are liver disease, pancreatitis and gastrointestinal cancer. Other alcohol‐related intestinal dysfunction is common but not life‐threatening, leading to diarrhoea, malabsorption and nutritional deficiencies. This review describes non‐neoplastic and neoplastic alcohol‐related disorders of the gastrointestinal tract, omitting the liver, which has been reviewed elsewhere.
