Functional Dyspepsia

Functional dyspepsia is a term used to describe recurring signs and symptoms of indigestion that have no obvious cause. It is one of the most common functional gastrointestinal disorders, characterized by persistent pain or discomfort in the upper abdomen. Unlike an ulcer, which is a physical sore in the stomach lining, functional dyspepsia is a disorder of sensation and movement. Patients often experience "early satiety"—feeling full shortly after starting a meal—as well as bloating, belching, and a burning sensation. Because the stomach appears normal during an endoscopy, the condition is often attributed to the stomach’s inability to relax properly to accommodate food or an oversensitivity of the stomach lining to acid and stretching.

Treatment for functional dyspepsia is highly individualized because the triggers vary from person to person. Doctors may suggest a combination of dietary changes, such as eating smaller, more frequent meals and avoiding high-fat foods that slow stomach emptying. Medications like Proton Pump Inhibitors (PPIs) can help if acid sensitivity is a factor, while prokinetic agents may be used to improve stomach motility. In cases where the nerves of the stomach are hypersensitive, low-dose neuromodulators (tricyclic antidepressants) are often effective at "numbing" the pain signals. Managing stress and anxiety is also a key component, as the gut-brain axis plays a major role in how upper GI sensations are processed.
