Video: Colonoscopy with polypectomy GERD KRISTEN HEBERT What is GERD? GERD - Gastroesophageal Reflux Disease When acid from the stomach is allowed to travel backwards into the esophagus Due to a weak or malfunctioning Lower Esophageal Sphincter (LES) This causes irritation and damage to the esophagus Symptoms Frequent heartburn Often worsens after lying down Bitter taste in the mouth Vomit Breath Sore throat Chest pain Difficulty swallowing Feeling of a lump in your throat Dry cough What often triggers GERD? Diet Choices: Peppermint, fried or fatty foods, spicy foods, coffee, chocolate and alcohol Cigarette smoking Obesity Pregnancy Lying down immediately after eating Conditions such as Hiatal Hernia and delayed stomach emptying Why is it a problem? Esophagitis Narrowing of the esophagus (Esophageal stricture) Hoarseness and vocal problems Difficulty breathing, shortness of breath Tooth decay Ulcers in the esophagus Higher chance of esophageal cancer Reduced quality of life Ulcers Stricture Cancer Tooth Decay How is it diagnosed? Symptoms Barium Swallow x-ray Endoscopy pH monitoring If video does not work, click here. How to manage GERD Medications ◦ Antacids ◦ H2 Blockers ◦ Proton pump inhibitors Maintain a healthy weight Eat smaller meals and avoid foods that trigger heartburn Elevate the head of your bed Don’t lie down immediately after meals Avoid smoking Extreme cases- surgery to improve lower esophageal sphincter Works Cited http://www.webmd.com/heartburn-gerd/guide/ http://www.mayoclinic.org/diseasesconditions/gerd/basics/definition/con-20025201 http://www.health.com/health/gallery/0,,20496029,00.html Food allergies (“food hypersensitivity”) Definition: abnormal response to food triggered by immune system 8 1 2 5 3 6 Top 8= 90% of reactions Dairy Eggs Peanuts Tree nuts Fish Shell fish Soy Wheat 7 4 • 1/3 people either have a food allergy or modify fam. diet Can be • More likely if in family outgrown!! • Affects 6-8% of children • About 4% adults • Can be life threatening →Anaphylactic shock If you are allergic to: Birch pollen Ragweed pollen Grasses Mugwort pollen You may also have a reaction to: Apples Carrots Celery Hazelnuts Peaches Pears Raw potatoes Bananas Melons (cantaloupe, honeydew and watermelon) Melons (cantaloupe, honeydew and watermelon) Orange Peanut Tomatoes White potato Apples Bell pepper Carrots Celery Garlic Onion Some spices (caraway seeds, parsley, coriander, anise seeds, fennel seeds) Treatment: -Avoid the food!! -Read your food label/ingredients! *In Emergencies: Epipens* Sites Used.. • http://www.mayoclinic.org/diseases-conditions/food-allergy/expert-answers/food-allergy/faq20058538 • http://www.mayoclinic.org/diseases-conditions/food-allergy/basics/definition/con-20019293 • http://www.webmd.com/allergies/guide/food-allergy-intolerances • http://www.mayoclinic.org/drugs-supplements/epinephrine-injection-route/proper-use/drg-20072429 • http://www.mayoclinic.org/diseases-conditions/food-allergy/in-depth/food-allergies/art-20045949 Lactose Intolerance • Lack of lactase allows lactose to reach large intestine (colon) undigested. • Bacteria “feast” on lactose producing acids and gasses bloating, cramping, gas, diarrhea, etc. • If you avoid all dairy your diet is likely to be deficient in calcium and possibly vit. D Living with Lactose Intolerance 1) Purchase lactose free dairy products. 2) Make it part of a larger meal. 3) Spread out your dairy intake over several meals. 4) Take lactase tablets 30 minutes prior. 5) Use alternate sources to avoid calcium deficiencies. Alternative sources of calcium • Spinach • canned salmon • sardines with bones • calcium-fortified orange juice, • raw broccoli • canned white tuna • calcium-fortified soy milk • Dark green leafy vegetables • Almonds Lactose Intolerance vs. Milk Allergy Know the difference Q&A
