Figure 1 Annual totals and changes over time in number of patients undergoing colonoscopy for overt lower gastrointestinal bleeding, requiring hospitalization, requiring transfusions, and using antithrombotic drugs and nonsteroidal anti-inflammatory drugs (1995 to 2013). The incidence of lower gastrointestinal bleeding (LGIB) started to increase rapidly in 2002-2003, associated with increases in the number of patients hospitalized, receiving blood transfusions, using antithrombotic drugs (ATDs), and using nonsteroidal anti-inflammatory drugs (NSAIDs).
