I have a problem. i can only poop once a week. this has been like this for ever. what can i do to go more?

Fiber/fluids: More than likely, given your age, you suffer from chronic constipation or irritable bowel syndrome-constipation predominant. I would start by increasing your daily fiber intake to 30 grams per day ( ie fiber one cereal) and drink 2 l of non-caffeinated beverage daily. A visit to a gastroenterologist for an evaluation is warranted if that doesn't do the trick.
