Transcript Digestion # 2

Problems of the Digestive System
 ulcer: a hole or sore inside the stomach or small intestine
often caused by H-Pylori bacteria
 Our stomachs are covered by mucus which protects the lining.
 heartburn: is when stomach acids move up the
esophagus. We call it "heartburn" but it is from the
esophagus which is behind the heart. Eating too much or
irritating foods can cause heartburn. (Also called
G.E.R.D)
Gallstones
-Gallstones are pieces of solid material that form in the gallbladder
-These stones develop because cholesterol and pigments in the bile
sometimes form hard particles
Causes:
-Genetics
-Body weight
-Decreased motility of the gallbladder
-Diet
Treatment: Surgery
Digestive Disorders

and the immune system responds by damaging the villi in the small
intestine and interferes with absorption of nutrients from food.

 Constipation -
too much water is removed from waste resulting
in stools that are too hard and difficult to excrete (Increase fiber in diet
and get enough fluids to prevent this )
 Choking - food is trapped in windpipe (failure of epiglottis to close
the airway when swallowening)
Lactose Intolerance
 Is the inability to digest a lot of lactose (sugar found in
milk).
 Caused by a shortage of the enzyme lactase
Salmonella
 Salmonella - Bacteria found on raw chicken and
eggs...undercooked meat can cause salmonella
poisening which can lead to death
 Ecoli - Bacteria that live in the intestinal tracks of
animals and birds and is transmitted to humans
when we eat food that is contaminated with animal
feces.
Colitis
 Is a disease involving the inflammation of the colon
or other parts of the large intestine.
 Chrons disease is a type of inflammatory colitis. It is
a chronic inflammatory disease affecting mostly the
small and large intestine.
 Occurs when the body’s immune system, attack your
body’s own tissues
Appendicitis
 appendix becomes blocked with mucus causing the
bacteria that usually lives in your appendix to become
infected and then multiply resulting in inflammation.
