- Low HDL
- Hypertension
- Hyperglycemia

what are three common medical diagnoses associated with developing a hiatal hernia
- nonerosive GERD (1/4 of patients develope HH)
- severe erosive esophagitis (3/4)
- barretts esophagus (90%)
what is the pathophysiologic cause of hiatal hernias
Caused by movement of the LES above the diaphragm
what is the difference between a sliding esophageal hernia (type 1) and a paraesophageal hernia (type 2)
- sliding is widening of the hiatal tunnel causing the gastric cardia to herniate or “slide” upwards
- paraesophageal is laxity of gastric ligaments that normally prevent displacement of the stomach, this allows portions to be displaced above hiatal tunnel
95% are type 1
what are the MC risk factors for hiatal hernias
- being >50
- obesity
what is the presentation of a sliding hiatal hernia
increased frequency and severity of GERD symptoms!
what is the presentation of a paraesophageal hiatal hernia
- less GERD s/s than sliding
- epigastric pain
- postprandial fullness
- NV
what differentiates internal vs external hemorroids
- internal = above dentate line
- external = below dentate line
what are causes of hemorroids
increased venous pressure 2/2:
