Functional gastro-intestinal disorders (FGID) constitute a major portion of gastro intestinal practice & primary care. They are associated with significant absenteeism from work, impaired health related quality of life, and increased medical costFunctional dyspepsia is one of these functional disorders. It is defined according to the Rome II criteria as persistent or recurrent pain or discomfort centered in the upper abdomen. Dyspepsia subgroup classification is proposed for research purposes based on the predominant symptom into: Ulcer like dyspepsia when pain is the predominant symptom ; Dysmotility like dyspepsia when discomfort is the predominant symptom ; Mixed type dyspepsia where we cant precise the predominent symptom. It is important to know the type of dyspepsia as many patients with nonulcer dyspepsia (functional dyspepsia) are given medication unnecessarily. Subgrouping of functional dyspepsia based on symptoms to identify likely pathophysiological disturbances continues to be controversial but has the potential to help specifically target pharmacological therapy. This study was done on 310 patients of the Egyptianpopulation with ages ranging from 12 to 70 years, all having dyspeptic symptoms. After sheet questionnaire and investigations these patients were divided into two main groups. Group I including 110 patients proved to have organic dyspepsia. They were proved to have the following lesions 50 (45.45%) patients had peptic ulcer disease.19 (17.27%)patients had calcular cholecystitis, 23 (20.9%) patients had liver cirrhosis ,13 (11.81%) patients had fatty liver ,3 (2.72%) patients had diabetes (1st presentation) and 2(1.81%) patients had malignant gastric ulcer. Group II including 200 patients proved to have functional dyspepsia. They were subdivided into three subgroups:Subgroup II a included 74 patients (37%)proved to have ulcer like type dyspepsia where pain was the predominant symptom Subgroup II b included 75 patients (37.5%) proved to have dysmotility like type dyspepsia where discomfort was the predominant symptom . Subgroup II c included 51 patients (25.5%) proved to have mixed type dyspepsia where we can’t say which is the predominant symptom and this proves that functional dyspepsia is highly prevelant amongadult Egyptians suffering from dyspeptic symptoms
