Hi. I am 56 years old and have Hashimoto Syndrom. I have been struggling with constipation for a couple of years. I have had a colonoscopy 7 years ago and can not get another for 3 more years due to not having polyps. With that said, I feel as though the food I eat does not get passed my large intestine. Therefore, there is discomfort through the rest of the digestive track and I am producing hard and small stools. I have been keeping a journal of the meals I eat for the past month. I eat prunes, yogurt, vegetables, bran. But, to no avail.
