Hi. Thanks for your query, albeit short and specific. Noted the history and understood your concerns. Passing stools once or twice in a week may be your natural body clock or habit and may not be needed to take much of a treatment if no symptoms were present. But if there are any symptoms related to the defecation like pain, fullness, bloating or so, you need a proper clinical evaluation, examination and investigations like that of stool, blood and urine. X-ray of the abdomen in standing position to see for the fecoliths. Colonoscopy after proper preparation. CT scan of the abdomen. All thee will help for the proper diagnosis. If a medical cause then enema and laxatives should help you. If there is cany mass, polyp or cancer, you may need a definitive treatment with surgery or so as indicated.
