Study Notes
DIGESTION D5 Digestive Health
- Digestive disorders are discussed, including causes and treatments
- The concept of the gut microbiome and its role in human health will be introduced
- Canada's Food Guide recommends a balanced diet for the body's metabolic activities
- Food group intake varies by factors like age, gender, and lifestyle
- Ulcer forms when the protective mucus layer in the stomach erodes, often caused by acid-resistant bacteria (Helicobacter pylori)
- Smoking, caffeine, alcohol, and stress can worsen ulcer symptoms
- Inflammatory Bowel Disease (IBD) is a general term for intestinal inflammation
- Crohn's Disease, an autoimmune IBD, can affect any part of the digestive tract, often the ileum, and results in painful diarrhea and rectal bleeding
- Colitis, another autoimmune type of IBD, affects the innermost lining of the colon, and results in loose/bloody stool, cramping, skin lesions, and joint pain.
- Irritable Bowel Syndrome (IBS) is diagnosed when symptoms are present but no serious underlying cause is found
- Stress is an important factor in IBS
- IBS treatments include laxatives (for constipation), and sometimes antidepressants or a low-FODMAP diet
- Hepatitis is liver inflammation in three types: A (often from contaminated water), B (spread through sexual contact, highly contagious), and C (contracted from contact with infected blood)
- Cirrhosis occurs when scar tissue replaces healthy tissue in the liver, frequently caused by chronic alcoholism and/or Hep C.
- Gallstones are small, hard cholesterol-derived crystals that form in the gallbladder
- Risk factors for gallstones include obesity, alcoholism, and family history.
- Anorexia nervosa involves an intense fear of gaining weight combined with a distorted self-image, a BMI below 85% of recommended, and severe long-term effects like cardiac arrest.
- Bulimia nervosa involves recurrent episodes of food restriction followed by binge eating and behaviors meant to purge the body of food and prevent weight gain.
GUT MICROBIOME AND GUT-BRAIN AXIS
- The human microbiome is the community of native bacteria living in and on the human body
- There are 10 times more bacterial cells in the human body than human cells
- The microbiome plays a key role in human health and disease
- Different bacteria perform various functions in different parts of the body
- The gut-brain axis is the two-way communication between the central nervous system (CNS) and the enteric nervous system (ENS).
- This is influenced by factors of the gut microbiome, which plays a role in nutrient delivery, motility and secretion
- Microbes produce metabolites like butyrate, which can affect brain cells
- Cytokines can influence neurophysiology, and serotonin produced in the gut may influence signals in the brain.
