    Study Notes

    The Gastrointestinal Tract (GIT)

    • The GIT is a vital organ, comprised of an upper and a lower section.
    • The upper GIT includes the mouth, pharynx, epiglottis, esophagus, and stomach.
    • The lower GIT begins at the stomach and continues to the small intestine.
    • The stomach secretes acids, enzymes, and fluids to break down food.
    • Proteins undergo digestion in the stomach.
    • The pyloric sphincter regulates food passage into the small intestine and prevents backflow.
    • The small intestine houses enzymes for digestion, releasing energy from carbohydrates, proteins, and fats.
    • The small intestine cells absorb nutrients into the lymphatic system.

    Diseases of the Esophagus

    • Dysphagia: Difficulty swallowing.
      • Oropharyngeal Dysphagia: Difficulty in the initial stages of swallowing, affecting the oral cavity or pharynx.
        • A neuromuscular condition, often seen in stroke patients and the elderly.
        • Can cause nasal regurgitation, coughing during swallowing, and irritation.
      • Esophageal Dysphagia: Difficulty in the esophagus, preventing food transport from the mouth to the stomach.
    • Gastroesophageal Reflux Disease (GERD): A chronic condition where stomach acid flows back into the esophagus, leading to irritation.
      • Causes:
        • Heartburn
        • Indigestion
        • Asthma
        • A weak lower esophageal sphincter
        • Pregnancy
      • Potential complications:
        • Reflux Esophagitis: Inflammation of the esophagus due to acid reflux.
        • Barrett's Esophagus: A precancerous condition where esophageal cells are replaced with stomach-like cells.
    • Substances that weaken the lower esophagus:
      • Alcohol
      • Caffeine
      • Garlic
      • High-fat foods
      • Onions
      • Antidepressants
      • Calcium channel blockers
      • Smoking
      • Chocolate
    • Conditions that contribute to gastroesophageal reflux:
      • Obesity
      • Pregnancy
      • Wearing tight clothing

    Conditions that affect the stomach

    • Dyspepsia: A condition associated with indigestion in the upper abdomen.
      • Symptoms:
        • Bloating
        • Ulcers
        • Vomiting
        • Persistent bloating
        • Difficulty swallowing air (chewing gum, smoking, drinking with a straw)
        • Rapid weight loss
    • Gastritis: Inflammation of the stomach muscles.
      • Causes:
        • Infection
        • Nonsteroidal anti-inflammatory drugs (NSAIDs)
        • Alcohol
      • Acidobacteria, such as Acidobacter choleium, can contribute to gastritis.
    • Gastritis can hinder the absorption of iron and vitamins.

    Peptic Ulcer

    • An ulceration in the gastrointestinal mucosa (stomach walls) caused by gastric acid and pepsin.
    • Helicobacter pylori: A bacterium linked to peptic ulcer disease.
    • Zollinger-Ellison Syndrome: A condition possibly related to peptic ulcer (clarity needed from additional information).
    • Ulcers: Can be linked to alcohol, stress, smoking, and genetics.
    • Abdominal pain may be relieved by eating.
    • Gastric ulcers can lead to internal bleeding.

    How to Manage Dysphagia:

    • Prioritize soft, non-sticky foods.
    • Avoid dry foods, peanut butter, and cheese.
