Abdominal pain can originate from various parts of your body, from digestive organs such as your stomach and intestines to nearby organs such as the gallbladder, bladder, ovaries, and muscles in your abdomen. Common causes for abdominal discomfort may include infections, inflammation, blockages, or how the brain interacts with gut processes. Sometimes, the pain is linked to a clear issue, while in other cases, no clear cause might be found.
