Indigestion is subcategorized as either "organic" or "functional dyspepsia", but making the diagnosis can prove challenging for physicians. [6] Organic indigestion is the result of an underlying disease, such as gastritis , peptic ulcer disease (an ulcer of the stomach or duodenum ), or cancer . [ 6 ]
Functional dyspepsia (FD) is a common gastrointestinal disorder defined by symptoms arising from the gastroduodenal region in the absence of an underlying organic disease that could easily explain the symptoms. [3] Characteristic symptoms include epigastric burning, epigastric pain, postprandial fullness, and early satiety.

Simethicone tablets. Simeticone is used to relieve the symptoms of excessive gas in the gastrointestinal tract, namely bloating, burping, and flatulence. [2] [3] While there is a lack of conclusive evidence that simeticone is effective for this use, [4] [5] [failed verification] studies have shown that it can relieve symptoms of functional dyspepsia [6] and functional bloating.
Functional abdominal pain syndrome is a functional gastrointestinal disorder. [4] Functional gastrointestinal disorders (FGD) are common medical conditions characterized by recurrent and persistent gastrointestinal symptoms caused by improper functioning of the enteric system in the absence of any identifiable organic or structural pathology, such as ulcers, inflammation, tumors or masses.
