Final Exam Review Sheet

1. Causes of Celiac Disease
Celiac disease is a digestive autoimmune disorder that causes damage in the lining of the small intestine when foods with gluten are eaten. Glutens are a form of protein found in some grains. The damage to the intestine makes it hard for the body to absorb nutrients especially fat, calcium, iron and folate. The body’s immune system is designed to protect it from foreign invaders. When people with celiac disease eat foods containing gluten, there immune system forms antibodies to gluten which affect the intestinal lining. This causes inflammation in the intestines and damages the villi. (Villi are hair like structures on the lining of the small intestine). Nutrients from food are usually absorbed by the villi. If the villi are damaged the person cannot absorb nutrients properly and ends up malnourished no matter how much they eat.

2. Describe the Term Hiatal Hernia
Anytime that an internal body part pushes into an area where it doesn’t belong it’s called a hernia. The hiatus is an opening in the diaphragm, usually the esophagus (food pipe) goes through the hiatus and attaches to the stomach, but in a hiatal hernia the stomach bulges up into the chest through that opening. Two main types of hiatal hernias are sliding and paraesophageal (next to the esophagus).
Sliding Hiatal Hernia – is the most common type of hernia. In a sliding hiatal hernia the stomach and the part of the esophagus that joins the stomach slide up into the chest through the hiatus.
Paraesophageal Hernia- is less common but more concerning. Part of the stomach squeezes through the hiatus landing next to the esophagus. Even though u may not have symptoms it’s dangerous because the stomach can become “strangled” and have its blood supply shut off.
