Digestive Health Specialists in Arizona

Arizona's colorectal cancer screening rate has historically lagged behind the national average, a gap that the state's large uninsured population and shortage of gastroenterologists outside metro areas helps explain. Colorectal cancer is one of the most preventable cancers when colonoscopy catches polyps early, but roughly 40% of age-eligible Arizonans have not had a screening procedure. The shortage is not evenly distributed: Maricopa County has adequate GI capacity in most suburban markets, while counties like Yavapai, Mohave, and the tribal counties along the eastern part of the state have very few practicing gastroenterologists. Nonalcoholic fatty liver disease (NAFLD), now rebranded as metabolic-associated steatotic liver disease (MASLD), is escalating in Arizona faster than in most states. The state's high rates of type 2 diabetes and obesity, driven partly by dietary patterns across low-income communities and partly by the metabolic effects of heat on physical activity levels, feed directly into liver disease progression. Hepatology practices in Phoenix and Tucson are managing an increasing volume of cirrhosis cases and liver transplant evaluations, and Banner University's liver transplant program is one of a handful in the state with active waiting lists. The border health dimension shapes GI practice in southern Arizona in a specific way. Hepatitis B and C rates are elevated in immigrant populations from Mexico and Central America who use clinics in Tucson, Nogales, and Yuma. Gastroenterologists and hepatologists in these communities screen and manage viral hepatitis at volumes that reflect the border corridor's epidemiology rather than national population averages.
