Study Notes

  • Aging involves progressive and broadly predictable changes that are not homogenous, with organs aging at different rates influenced by genetics, lifestyle, and environment.
  • Aging increases susceptibility to diseases, resulting in diminished physiological reserves, a concept known as homeostenosis.
  • New GI complaints in older adults should be investigated for underlying diseases rather than attributed solely to aging.

Parts of the GI System and Aging

  • The oral mucosa epithelial lining thins, gums recede, and the risk of tooth decay increases with age.
  • Maxillary and mandibular bones shrink, leading to erosion of tooth sockets.
  • Taste recognition and detection of sweet, sour, salty, and bitter flavors decrease due to a reduction in the number and density of taste buds, ultimately leading to disinterest in food, anorexia, malnourishment, and weight loss.
  • Muscle contractions that initiate swallowing slow down, increasing pharyngeal transit time and potentially causing dysphagia.

Esophagus

  • Gastroesophageal Reflux Disease (GERD) is more common in the elderly due to decreased upper and lower esophageal sphincter pressure, impaired motility, decreased intra-abdominal lower esophageal length, and increased hiatus hernia.

Stomach

  • Aging-related changes in the stomach include decreased capacity, reduced mucosal prostaglandin, mucus secretion, blood flow, and bicarbonate, making it more prone to NSAID-induced damage and ulcers.
  • Intrinsic factor secretion is maintained, and peptic ulcer disease is correlated with NSAID use and physiological changes.

Small Intestine

  • The small intestine is relatively well-preserved but exhibits moderate villus atrophy and coarsening of mucosa.
  • Absorption of zinc and calcium decreases with age, Filipinos are generally vitamin D deficient.

Colon

  • Aging-related changes in the colon include atrophy of mucosa and muscularis propria, increased fibrosis and elastin, abnormal myenteric ganglia, and decreased muscle strength.
  • Reduced perception of anorectal distention, constipation, increased prevalence of atherosclerosis, and decreased colonic propulsive motility is common.
  • Diverticular disease is also common.

Liver

  • Livers become brown due to an increase in lipofuscin (a brown pigment with no clinical significance) and more fibrotic, with a decrease in hepatic volume and weight.
  • Phase I reactions decrease with age, while Phase II reactions are unaffected.

Pancreas

  • The pancreas experiences changes such as increased duct diameter, decreased weight, duct hyperplasia, and lobular fibrosis, but these changes have minimal clinical significance.

Gallbladder

  • Aging of the gallbladder results in decreased sensitivity to CCK, leading to an increase in gallstone prevalence.

Altered Signs and Symptoms - Anorexia of Aging

  • Physiologic factors, decreased salivation, altered smell and taste, dental disorders, memory loss, depression, social changes, polypharmacy, chronic conditions, and difficulty swallowing can all contribute.

Dysphagia

  • Esophageal motility abnormalities and extrinsic compression by the aorta can cause dysphagia.
  • Dysphagia aortica is mechanical obstruction of the esophagus due to compression from an abnormally dilated aorta, especially in older women with short builds, hypertension, and kyphosis.

Diarrhea

  • Dietetic indiscretions, food intolerance, medication side effects, and an increased susceptibility to infection.
  • Conditions like motility disorders or gastrointestinal surgeries can lead to luminal stasis, contributing to diarrhea.

Constipation

  • Immobility, perineal problems, medications, decreased fluid/caloric intake, and elevated toilet seats.

Fecal Incontinence

  • Loss of voluntary control of defecation causes anxiety, fear, embarrassment, and reclusiveness.

Fecal Impaction

  • Increased rectal compliance, impaired rectal sensation, misperceptions about bowel habits, and metabolic, muscular, or neurological diseases can cause fecal impaction.

Deciphering Nutrition Labels

  • Obesity is a pandemic; countries with lower BMIs now have high BMIs due to the adoption of Western diets.
  • Food item with a high sugar content typically contains high fructose corn syrup, corn syrup, honey, and dextrose.

Nutrition Facts Label

  • Lists nutrients from one serving of food in descending order from highest to lowest quantity.
  • The nutrition facts label includes serving size, calories, nutrients, % daily value, fats, cholesterol, sodium, carbohydrates, protein, vitamins, and minerals.

Parts of Nutrition Labels - Serving Size

  • This details the serving size and number of servings per container and helps calculate actual serving size.
  • The computation for the actual serving size is (servings per container) x (serving size)

Labeling Terms for Sodium

  • Salt/Sodium-free: < 5 mg of Na per serving
  • Very Low Sodium: ≤ 35 mg of Na per serving
  • Low Sodium: ≤ 140 mg of Na per serving
  • Reduced Sodium: At least 25% less Na than the original product

Nutrient Content on Nutrition Labels

  • 100 calories is moderate, while 400 calories or more is high
  • Aim low in saturated fat, trans fat, cholesterol, and sodium while aiming high in vitamins, minerals, and fiber.
  • A good source of a certain nutrient is 10-19% of the Daily Value per serving, whereas an excellent source is 20% or more.
