Some functional dyspepsia affects digestive function, such as those caused by gastrointestinal dyskinesia, while those caused by visceral sensory hypersensitivity do not affect digestive function.
Functional dyspepsia is a disorder of gastric and duodenal function, resulting in a feeling of fullness and belching after meals, accompanied by pain and burning sensation in the upper and middle abdomen, with no organic lesions of the stomach and duodenum.
Gastrointestinal dyskinesia causes delayed gastric emptying and mismatched coordination of gastroduodenal motility, which affects digestive function and leads to functional dyspepsia.
Impaired gastric tolerance causes abnormal distribution of food in the stomach and decreased storage capacity, which also affects digestive function and triggers functional dyspepsia.
Functional dyspepsia caused by visceral sensory hypersensitivity, which triggers a decrease in the sensory capacity of the stomach and causes an early satiety sensation, does not affect digestive function.
Functional dyspepsia has more pathogenic mechanisms, different pathogenic mechanisms have different effects on digestive function, it is recommended to seek timely medical treatment, standardized treatment.
