This cross-sectional study aims to determine the prevalence of lactose intolerance among patients with chronic diarrhea, assess its correlation with age and gender, and evaluate common symptoms in affected patients. The study will collect demographic data, conduct lactose intolerance testing via PCR, and use a symptom questionnaire.
The study is designed as a cross-sectional analysis conducted at a single healthcare center. Its primary objectives are: To determine the point prevalence of lactose intolerance in patients suffering from chronic diarrhea (lasting more than four weeks). To explore potential correlations between lactose intolerance and demographic factors such as age and gender. To identify the most common symptoms associated with lactose intolerance in this patient population. Methodology: Data Collection: Demographic information (age, sex, medical history, and diarrhea duration) will be gathered. Lactose Intolerance Testing: Polymerase Chain Reaction (PCR) will be employed to diagnose lactose intolerance. Symptom Questionnaire: A standardized questionnaire will be administered to document symptoms like abdominal pain, bloating, flatulence, diarrhea, and nausea.
