Problems of the Digestive System
Indigestion
Heartburn
Gas
Constipation
Nausea
Diarrhea
Lesson 2
Indigestion can be caused from eating too much food, eating too quickly, and eating foods that are spicy or high in fat.
Indigestion
Problems of the Digestive System
This feeling of fullness can sometimes be accompanied by gas and nausea.
Stomach disorders and stress can contribute to indigestion.
Lesson 2
Heartburn
Heartburn results from acid reflux, or the backflow of stomach acid into the esophagus, which causes a burning sensation.
Problems of the Digestive System
Heartburn can also be a symptom of a hiatal hernia.
Frequent or prolonged heartburn can be an indication of more serious digestive disorders.
Lesson 2
Gas
Excessive gas can result in cramps or an uncomfortable feeling of fullness in the abdomen.
Problems of the Digestive System
Most foods that contain carbohydrates or complex sugars can cause gas.
Fats and proteins produce less gas than carbohydrates.
Lesson 2
Constipation
Problems of the Digestive System
It can be caused by not drinking enough water or consuming enough fiber to move wastes through the digestive system.
Following a diet of fruits and vegetables, drinking at least eight 8-ounce glasses of water each day, and getting regular physical activity are the best ways to avoid constipation.
Laxative drugs may be used to treat constipation but can cause diarrhea, abdominal cramps, and gas.
Constipation is a condition in which feces become dry and hard and bowel movements are difficult.
Lesson 2
Nausea
Problems of the Digestive System
Nausea is the feeling of discomfort that sometimes precedes vomiting.
Motion sickness, pathogens, some medications, and dehydration can cause nausea.
Vomiting is a reflex in which the contents of the stomach are brought back up the esophagus and out of the mouth.
Lesson 2
Diarrhea
Diarrhea is the frequent passage of watery feces that results when digested food passes too quickly through the large intestine.
Problems of the Digestive System
Diarrhea may result from changes in eating style, overeating, emotional turmoil, or nutritional deficiencies.
To avoid dehydration during an episode of diarrhea, drinkplenty of water and other fluids.
Medical attention should be sought if diarrhea persists formore than 48 hours.

Peptic ulcer
Cirrhosis
Crohn’s disease
Colon cancer
Colitis
Hemorrhoids
Tooth decay
Lesson 2
Gallstones
Problems of the Digestive System
Gallstones are formed when cholesterol in bile crystallizes andblocks the bile duct between the small intestine and thegallbladder.
Symptoms include pain in the upper right portion of the abdomen, nausea, vomiting, and fever.
Treatment includes taking medication that dissolves the stones or having the stones broken down by high-intensity ultrasound waves.
Lesson 2
Appendicitis
Problems of the Digestive System
Appendicitis is caused if bacteria or other foreign matter block the appendix and prevent the release of its secretions.
Symptoms of appendicitis include pain in the lower right portion of the abdomen, fever, loss of appetite, nausea and vomiting, and tenderness in the area of the appendix.
Treatment involves surgical removal of the appendix.
Lesson 2
Gastritis

Symptoms of gastritis include pain, indigestion, decreased appetite, and nausea and vomiting.
Treatment includes avoiding irritants and taking medicationsor antibiotics to eliminate infection.
Problems of the Digestive System
Lesson 2
Lactose Intolerance
Lactose intolerance involves insufficient production of lactase, so undigested lactose remains in the small intestine.
Bacteria in the digestive tract ferment ingested lactose, which leads to abdominal cramps, bloating, gas, and diarrhea.
People who are lactose intolerant should choose alternate sources of calcium, such as fortified soymilk.

Lesson 2
Peptic Ulcer
Peptic ulcers can be caused by regular use of anti-inflammatorydrugs such as aspirin and by a bacterial infection caused by Helicobacter pylori.
Symptoms include nausea, vomiting, and abdominal pain that worsens when the stomach is empty.
Treatment includes medications that neutralize acid or eliminate infection and avoiding irritants such as aspirin, cigarette smoke, and alcohol.

Lesson 2
Cirrhosis
Destruction of liver tissue, usually caused by prolonged and heavy alcohol use, results in cirrhosis, or scarring of the liver tissue.
Alcohol interferes with the liver’s ability to break down fats.
Liver tissue is destroyed and replaced with useless scar tissue, preventing normal liver function.
Cirrhosis can lead to liver failure and may cause death unlessa liver transplant is performed.

Crohn’s Disease
