What can a person who has not been to the toilet for over two weeks do, to go to the toilet?

Poopless?: Each person with constipation needs to be sure there is no other disease causing it. If constipation is just due to slow movement of the food and poop through the gut, there are many treatments such as: vegetables, water, prune juice, prunes, fiber plus water, miralax (polyethylene glycol), Senokot or other senna, an enema, milk of magnesia, other laxatives, etc... A doctor can evaluate if needed.
