Study Notes
Digestive System Diseases
- Diseases of the digestive system encompass various conditions affecting the oral cavity, esophagus, stomach, and other parts.
- Upper GI disorders involve the oral cavity, esophagus, and stomach.
- Thought and emotional factors can influence digestive system health and function.
- Malnutrition and nutrient deficiencies are secondary diseases that can result from GI disorders.
- Nutritional support is crucial in managing and preventing complications in digestive system disorders.
Assessment of GI
- Unintentional weight loss is a significant indicator of GI issues.
- Severe malnutrition is defined by percentages of weight loss over time.
- % ideal body weight (Ibw), body mass index (BMI) are used in assessing patients with GI problems.
- Symptoms like nausea (N/V), diarrhea, and dysphagia can signal GI issues.
- Allergies to food and/or medications may affect GI health.
- Lab tests like blood tests (CBC, ferritin, B12, folate) are used to assess the patient's nutritional status.
Digestion
- Digestion involves a mechanical breakdown (physical) and chemical breakdown of food using enzymes.
- Enzymes like salivary amylase, lipase, and pepsin are crucial for digestion.
- Pancreatic enzymes (lipase, protease, amylase) and bile salts also play important roles.
- The small intestine is where most of the absorption of nutrients occurs.
- Various factors can affect digestion and absorption (e.g., medications, diseases, and malnutrition).
Types of Digestion
- Pancreatic phase involves pancreatic enzymes released into the small intestine.
- Intestinal phase involves enzymes released from the small intestine, breaking down remaining nutrients.
- Maldigestion involves issues with any step of digestion, including problems with normal stomach emptying.
Absorption
- Absorption involves taking nutrients and transporting them into the bloodstream.
- Mostly occurs in the duodenum, with absorption of monosaccharides, amino acids, and fatty acids.
- Fat-soluble vitamins (e.g., vitamins A, D, E, K) require bile for absorption.
- Water-soluble vitamins (e.g., B vitamins and C) are absorbed into the intestinal mucosa.
- Malabsorption can arise from various problems (e.g., issues with digestive enzymes, infections).
Functional and Organic Diseases
- Functional diseases don't have structural damage (e.g., ulcerative colitis).
- Organic diseases involve actual structural damage to tissues (tissues).
- Stress and emotional factors can impact digestive function.
Esophageal Diseases
- The esophagus is a muscular tube connecting the pharynx to the stomach.
- Problems with esophageal sphincters (e.g., lower esophageal sphincter (LES)), can cause GERD.
- GERD is gastroesophageal reflux disease.
- Esophageal disorders can be obstructive, inflammatory, or nervous in nature.
GERD (Gastroesophageal Reflux Disease)
- GERD involves reflux of stomach contents into the esophagus.
- Symptoms include heartburn, substernal pain, belching, and esophageal problems
- GERD can impact adults between 20% to 40%.
- Diagnosis is often based on an upper endoscopy.
GERD Pathophysiology
- GERD involves a complex interplay of reduced lower esophageal sphincter pressure, mucosal irritants, decreased gastric motility, and increased intra-abdominal pressure.
- Pregnancy, oral contraceptives, and other factors can contribute to GERD problems
- Specific treatments vary.
