Digestion Related Disorders

1. Digestion Related Disorders

2. The digestive system • A collection of organs that work together to digest and absorb food. • Includes mouth, esophagus, stomach, intestines, and accessory organs.

3. What organs are affected? • Digestive related disorders can affect one or more of the digestive organs.

4. Disorders • Gastroesophageal reflux disease (GERD) • Lactose intolerance • Ulcers • Appendicitis • Irritable Bowel Syndrome

5. Gastroesophageal Reflux Disease(GERD) • AKA acid reflux • Chronic digestive disease that occurs due to repeated backflow of stomach acid to the esophagus • Causes irritation of esophagus

6. Symptoms • Heartburn – most common • Regurgitation of food or sour liquid • Coughing • Chest pain • Difficulty swallowing • Nausea

7. Treatments • Lifestyle changes • Dietary changes: avoids certain foods(fatty foods, alcohol, acid-containing foods) • Stop Smoking • Chewing gum • Light exercise after meal • Elevate upper body in bed • OTC medication • Antacids – tums, pepto, milk of magnesia • Histamine antagonists • Proton Pump Inhibitor (PPI) • Surgery • 80% success rate • Risks

8. Current news • Stretta Procedure • Type of endoscopic surgery; AKA Minimally Invasive Surgery(MIS) • Uses radiofrequency waves to strengthen the lower esophageal sphincter • Quick procedure and quick recovery time.

9. Lactose Intolerance • The inability or insufficient ability to digest lactose • Caused by a deficiency of the enzyme lactase • Lactase breaks down lactose into glucose and galactose for absorption by the small intestine • Three causes: • 1) Congenital – absence of lactase from birth due to a mutation; very rare • 2) Secondary – diseases that destroy lactase in the small intestine • 3) Primary(Developmental)– natural decrease in lactase after childhood; most common • can vary among different ethnic groups • almost 100% of Asians • 80% of American Indians • 70% of Blacks • 20% of Caucasians

10. Symptoms • Abdominal pain • Abdominal bloating • Gas • Diarrhea • Nausea • Flatulence (passing gas) • Varies in severity among different people

11. Treatments • Dietary changes • Reduce intake of lactose • Milk substitutes such as soy and rice milk • Ingest milk-containing foods during meals. • Supplements of lactase enzyme • Adaptation • Slowly increasing intake of lactose

12. Current News • There is no cure for lactose intolerance

13. Ulcers * Ulcers are sores/wounds located on your digestive track. * Affect about 4 millions Americans a year. * Esophagus, stomach, duodenum. * duodenal ulcers/peptic ulcer- Ulcers located at duodenum (Commonly found here) * gastric ulcers- Ulcers located in stomach. * esophageal ulcers- Ulcers located in esophagus. *Not often too serious, just stomach pain. Sometimes symptoms may not even show. *Serious ulcers often start to bleed. - Perforation: When ulcers start get bigger and break through stomach area. - Obstruction: Stops food from going into stomach when results to vomiting, nauseousness, and weight-loss.

14. Causes of Ulcers: * Before, doctors mistaken it was due to stress or consuming food with too much acid. Digestive tract can be damaged if theres a large amount of acid in the body or digestive tract is already impaired to begin with. * Stress can contribute to worsening an ulcer but does not produce one. *It may be what you eat that produces ulcers, but it depends on different people. *Drinks/food with caffeine or are decaffeinated are most likely to worsen the pain. *After research, ulcers have been proven to be caused by an infection & by anti-inflammatory medicines. *Caused by infection - Helicobacter pylori/H. Pylori *Caused by anti-inflammatory medicines - Long usage may cause ulcers to produce. - Examples: Aspirin, Ibuprofen (one brand name: Motrin), Naproxen (brand name: Aleve), Ketoprofen (brand names: Actron, Orudis KT) and some prescription drugs for Arthritis.

15. Peptic Ulcers Esophageal Ulcers Gastric Ulcers

16. Symptoms: - After you consume food/drink you start to feel worse about an hour or 2 later - After you consume food/drink you feel worse - Waking up feeling pain in the stomach - Getting full quick - Heavy feeling - Bloating - Stomach feels like it's burning - Vomiting *Vomit food from days before(severe ulcer) - Losing weight

17. Treatment/Medicine: * Eliminating the H. pylori bacteria(triple therapy) - Triple therapy: eliminating H. pylori bacteria with collaboration of two antibiotics bismuth subsalicylate (Pepto- Bismol).Triple therapy lessens acid stomach produces. - Other combinations *H2 blockers & proton pump inhibitors - Lessens acid that your stomach produces. You should feel better within 3 days. *Antacids - acid in stomach gets neutralized. *Sucralfate - covers the ulcer in order to shield it from the acid so it eventuall heals. *Misoprostol - lower down amount of acid in body & shields lining of stomach commonly used by those who need to take anti-inflammatory drugs. * Ulcers go away within 2-3 weeks. If symptoms come back, it is recommended to change in to a another type of medicine or take low dosage regardless if there are no ulcers just to keep it from reappearing.

18. Tips: * Refrain from alcohol & smoking. ( damages digestive tract) * Don't use anti-inflammatory drugs like aspirin & ibuprofen. * Obtain caffeine little as possible. * Don't consume spicy food that causes head burn.

19. Appendicitis: - inflammation of appendix. - appendix: small pouch connected to large intenstine. * It is possible to live without an appendix. - most common causes of emergency abdominal surgery in U.S. - Causes: * Blockage by stool, a foreign object, or sometimes a tumor(cancer).

20. Symptoms: • It varies. However, its harder to cure when it comes to children, the elderly , and older women who are trying to have kids. • First symptom is usually around the belly button that becomes more severe if not treated. • When pain gets more severe it migrates to right lower abdomen and above the appendix (McBurney's point). • Could get peritonitis(inflammation of abdominal cavity) • Other symptoms that occur later: Fever, Nausea, Vomiting, Loss of Appetite, Diarrea, Constipation, Chills, Shaking

21. Tests: • Doctors test to see if you have Appendicitis by putting pressure to where your belly button is located. • Usually they can tell by symptoms you indiciate. Abdominal CT scan: x-ray images of the abdomen.     • Abdominal ultrasound: Diagnostic laparoscopy (surgery to look directly) • Before they also used a drug called NeutroSpec, but it was eliminated due to severe side effects.

22. Treatment: •  Appendectomy (removing appendix) • Removing appendix even if its okay to look into your abdomen for other explanations of pain • Get treated for infection from having abscess (dead neutrophils) after rupture of appendix and then getting your appendix removed. • * rupture causes patient to heal slowly

23. Irritable Bowel Syndrome(IBS)

24. What is IBS? • Chronic problem with the large intestine • Food moves through intestines too quickly or too slowly • Causes discomfort and emotional distress • Does not damage large intestine

25. Symptoms of IBS • Bloating and Gas • Mucus in the stool • Constipation • Diarrhea after eating or first thing in the morning • Alternating between Constipation and Diarrhea • Feeling like you need to have bowel movement after just having one • Feeling strong urges to have bowel movement • Abdominal pain and cramping that goes away after bowel movement

Many foods, such as apples, beans and citrus fruits, contain soluble fiber. Psyllium, a natural vegetable fiber, is a also a soluble fiber. You can buy psyllium supplements (some brand names: Fiberall, Metamucil, Perdiem) to drink and you can add it to other foods. • Insoluble fiber helps constipation by moving material through your digestive system and adding bulk to your stool. Insoluble fiber is in whole grain breads, wheat bran and many vegetables.
