AbstractA considerable portion of the world's population practices fasting, for religious purposes like Ramadan or to adopt a healthier lifestyle such as intermittent fasting. During this period, individuals undergo metabolic changes that alter their internal environment. The literature was analysed to identify a possible relationship between fasting and the development of Helicobacter pylori-induced peptic ulcers. This found that fasting does not affect the incidence of peptic ulcers, and studies that saw an increase in the incidence were not significant. However, remodelling of the gastric environment and increases in concentrations of H. pylori were recorded. There is no relationship between fasting and the risk of developing H. pylori-induced peptic ulcers, suggesting that individuals with uncomplicated ulcers are not at risk of developing further ulcers and can participate in fasts provided they take the recommended measures.
