Chapter 10.3 Digestive Disorders

Peptic Ulcers

  • A sore in the stomach/duodenum lining

    • Cause: a weakened mucus layer (used for acidic protection)– the tissue is then exposed to gastric gases

    • Symptoms: abdominal pain, bloating, nausea, loss of appetite

    • Treatment: antibiotics, meds to reduce acidity, no alcohol or smoking

Inflammatory Bowel Disease (IBD)

  • Chronic (meaning long-lasting) inflammation in the intestines

    • Cause: No known cause, possibly a defective immune system

    • Treatment: A special diet and prescribed medication

  • Crohn’s disease: Anywhere in the alimentary canal

    • Symptoms: Thinner bone/muscle development

  • Ulcerative Colitis: IBD in the large intestine

    • Symptoms: Bloody stools, cramps, abdominal pain

Constipation

  • Stool moves too slowly through the digestive tract, slow bowel movements of 2-3 per week, small/dry stools

    • Cause: Not enough water, weak nerve/muscle movement, not enough fibre, lack of exercise

Hepatitis A, B, and C

  • Liver inflammation

    • Cause: Caused by a viral infection

  • Types:

    • Hepatitis A: Caused through contaminated water

    • Hepatitis B: Caused through sexual contact (needs vaccine protection)

    • Hepatitis C: Caused through blood contact

Cirrhosis

  • Chronic illness, scar tissue starts to replace healthy tissue

    • Cause: Alcoholism, Hepatitis C

    • May result in liver failure

Gallstones

  • Cholesterol begins to form crystals in the gallbladder, soon growing into small/solid masses

    • Treatment: Ultrasound shock waves, medication, removal of gallbladder

Diabetes

  • Chronic illness, cells can’t make glucose

    • Cause: lack of insulin in the bloodstream

  • Types:

    • Type 1 Diabetes: An auto-immune disease, the pancreas stops producing an adequate amount of insulin (child–young adult)

    • Type 2 Diabetes: Caused by a lack of exercise, sometimes obesity (adult–)

    • Gestational Diabetes: Pancreas unable to produce enough insulin during pregnancy

  • Possibly 5 Types, according to a Swedish Study in 2018

    • Cluster 1: Severe autoimmune diabetes (also known as Type 1)

    • Cluster 2: Severe insulin-deficiency

    • Cluster 3: Severe insulin resistant

    • Cluster 4: Mild-obesity related

    • Cluster 5: Mild-age related

  • Treatment:

    • Daily insulin injections/insulin sprays, expensive

    • Trijardy: 3 medications prescribed for Type 2

      • Metformin, Empagliflozin, and Linagliptin

    • Rybelsus: Hormonal injection of glucagon (similar hormone to peptide), it stops the liver from producing an excess amount of sugar and helps the pancreas to make more insulin

      • However, it risks creating thyroid tumours

Endoscopy

A procedure in which an instrument is introduced into the body to give a view of its internal parts.

  • A camera and light are attached to a tube that’s slowly sent down the alimentary canal

  • The process can confirm medical problems, observe illness difficult to see through a x-ray, and allows for doctors to visually see the inner lining
