• Hydrochloric acid bubbles up esophagus
• Antacids help neutralize HCL
• Bulging of stomach through esophageal hiatus
• Narrowing of pyloric sphincter by enlarged muscle fibers

• First performed in 1989- 21 month old received part of Mother’s liver
– Liver regenerates well
• Also been done for pancreas, kidney and bone marrow
• Yellowish color of sclera, skin, and mucous membranes due to build up of bilirubin
• Three catagories– Excessive production of bilirubin– Dysfunction of liver cells– Blockage of bile drainage
• Formed as a result of precipitation of cholesterol and bile salts in gall bladder
• Diagnosed by ultrasound
• Often no symptoms
• If obstructing the gall bladder, severe pain in upper right side of abdomen
• Can be removed by surgical procedures
