| pubmed-article:11825655 | pubmed:abstractText | The changes in PYY in several gastrointestinal disorders and their possible clinical implications are reviewed. The changes in PYY seem to be an adaptive response to alterations in the patho-physiological condition caused by the disease. This becomes evident in gastrointestinal disorders such as diabetes gastroenteropathy, inflammatory bowel diseases, celiac disease, systemic sclerosis and post-intestinal resection state. On the other hand, changes in PYY in chronic idiopathic slow transit constipation appear to be primary and could be one of the etiologic factors of the disease. PYY does not seem to be involved in colorectal carcinoma. Although gastrointestinal dysmotility in neuro-muscular diseases is evident, PYY is not affected. The changes in PYY in gastrointestinal disorders could be beneficial in clinical practice. Thus, in cases where an increase or decrease in PYY is desirable, a diet that increases or decreases PYY synthesis and release can be followed, or a receptor agonist or antagonist can be utilized. | lld:pubmed |
