老年人消化系统的功能特点古人云:“年老者胃日弱,容纳少而传化迟;老人肠胃皮薄,多则不消,膨腹短气”。也就是说老年人消化机能减退,表现在口腔、食管、胃肠及肝脏、胰腺均老化。口腔黏膜随增龄而角化增加,唾液腺萎缩、唾液分泌减少;舌和咬肌萎缩,咀嚼无力,舌味蕾减少,味觉减退;牙龈退化萎缩,牙齿脱落;食管老化,蠕动及收缩力减弱。胃黏膜萎缩,胃液分泌减少。40岁起,胃蛋白酶原分泌明显减少,胃的消化作用减弱。60岁以上的老年人约有35%为盐酸偏低或缺乏,对进入胃细菌的杀灭作用减弱或丧失,促胰液素的释放亦降低。胃平
The features of the elderly digestive system Ancients said: “The elderly stomach weak day, containing less transfer delay; the elderly gastrointestinal skin thin, and more do not eliminate, abdominal distension short.” In other words, the elderly digestive function decline, manifested in the mouth, esophagus, gastrointestinal and liver, pancreas are aging. Oral mucosa increased with age and keratosis increased salivary gland atrophy, decreased saliva secretion; tongue and masseter muscle atrophy, chewing weakness, decreased taste buds, taste buds; gingival degeneration and atrophy, tooth loss; esophageal aging, peristalsis and contractility weakened. Gastric mucosal atrophy, decreased gastric secretion. 40 years old, pepsinogen secretion was significantly reduced, the digestion of the stomach weakened. About 35% of elderly people over the age of 60 are low or low levels of hydrochloric acid, a weakened or loss-killing effect on gastric bacteria, and a decrease in the release of secretin.
