Older Adult by Mind Map: Older Adult

1. Gastrointestinal

1.1. Age related changes

1.1.1. Teeth Dentin production decreases and it become more fibrous. This causes teeth to become more fibrous. Nerve chamber become more narrow Causes less sensation in the teeth. Bone density lessens Increases the number of cavities on the teeth Gingiva retract Tooth loss is typical of aging

1.1.2. Tounge Taste sensation is decreases Sweet sensation is lost more so than sour, salty, and bitter sensations.

1.1.3. Saliva 1/3 the production amount t compared to young adults.

1.1.4. Jaw Mastication becomes harder as the muscles in the jaw become weaker

1.1.5. Esophagus Delayed esophageal emptying and dilation occur Discomfort can result as food stays in the esophagus longer Decreased gag reflex

1.1.6. Stomach Decreases motility Decrease in pepsin and hydrochloric acid production result in poorly digested food and indigestion

1.1.7. Small intestine Fat absorption is slower Vitamin B, B12, D, calcium, iron, dextrose, and xylose absorption are decreased

1.1.8. Large intestine Decrease in mucus production Makes it more difficult for stool to pass through the intestinal walls Loss of sensation in the internal sphincter, and fewer nerve impulses to the lower bowel Makes it more difficult for an older adult to know when they need to evacuate their bowels.

1.1.9. Liver Decreased ability to stabilize cholesterol Causes increased incidence of gallstones

1.1.10. Pancreas Ducts become dilated, and the entire organ prolapses eventually

13.1.3. Hope Expectation for something in the future Some look forward to the wonders of tomorrow Hope gets some through their suffering because they know better things lie at the end

13.1.4. Dignity Since worth in most of the world is determined by appearance, and status, older adults look toward their relationship with God for dignity and worth

13.1.5. Foregiveness Forgiving others and allowing others to forgive you is an important part of aging, as it mends relationships that are important in the later years

13.1.6. Gratitude Losses are typically great in old age, and being grateful for what a person had, or hat they still have is helpful in combating the negative emotions of loss

13.1.7. Transcendence This allows older adults to feel they are part of something greater, which makes dealing with difficult situations easier

13.1.8. Expression of faith Prayer, scripture reading, rituals, all help a person to become more in tune with their faith and they are important practices as older adults Spiritual distress can make it seem like God has abandoned a person, or they are not worthy. This can have detrimental effects on a persons mind and health, and they need to be consoled.

14. Nutrition

14.1. Human needs changes

14.1.1. Fiber Soluble fibers decrease cholesterol, improve glucose control in diabetics, and prevents obesity. Increased fiber reduces risk of colon cancer

14.1.2. Carbohydrates Reduce carb intake! Increased intake of carbs can cause unusually high release of insulin, causing hypoglycemia
