I have not had a bowel movement in 6 days, what should i do?

Constipation: If lifestyle changes don't help (such as drinking plenty of fluids and increasing fiber), then simple over the counter remedies to try would be milk of magnesia or miralax (polyethylene glycol). You can try taking these several days in a row until you get an effect (as long as you are not having pain, nausea or vomiting) if simple things such as this don't work then i'd advise seeing your physician.
