What are long term effects of Down syndrome?

Long-term (chronic) constipation problems. Sleep apnea (because the mouth, throat, and airway are narrowed in children with Down syndrome) Teeth that appear later than normal and in a location that may cause problems with chewing. Underactive thyroid (hypothyroidism)
