Gastro intestinal disease/medicine Flashcards
functions of GI tract
1) turns food into energy
2) waste removal
3) intake of water – hydration
key symptoms associated with GI disfunction
vomiting haematemesis weiht loss jaundice melaena diarrhoea abdominal pain
dysphagia
difficulty in swallowing
dysphagia problem types
oropharyngeal
oesophageal
gastric
history of dysphagia
duration solids or liquids pain weight loss previous MH medications SH
oropharyngeal dysphagia
difficulty initiating swallowing
difficulty with choking, nasal regurgitation
drooling, hardness etc
after initiation of swallowing at pharynx and upper oesophageal spincter
what can cause oesophageal dysphagia
benign musocsal disease (reflux may be benign peptic structure) or maligant or motility disorder (oesophageal spasm , achalasia, oesophageal pouch)
gastric dysphagia
carcinoma
outlet obstruction
peptic ulceration
pharyngeal pouches
defect between constrictor and transverse cricopharyges muscle
- due to incoordiantion of swallowing in pharynx, leads to herniation through cricopharyngeal muscle leading to formation of pouch
diagnosis oh pharyngeal poiches
barium swallow
management of dysphagia
treat underling cause
if nutritionally deplete may need supplementation
what leads to upper abdominal discomfort and cause
gastro oesophageal reflux disease
- excessive relaxation of lower oesophageal sphincter and raised intra abdominal pressure
symptoms of gastro oesophageal reflux discomfort
- heartburn
- epigastric pain
- acid reflux
- waterbrash
- nausea
- vomiting
- tooth decay
- asthma
management of pts with reflux
lifestyle advice (avoid late meals, sleep upright, weight loss, smoking cessation, reduction in alcohol
surgery
H2 agonist (release symptoms)
PPI
PPI examples
proton pump inhibitors
omeprazole
lansoprazole
hiatus hernia
pressure lost between the abdonomal and thoracic cavities
leads to reflux
types of hiatus hernia
prestage
sliding hiatal hernia
paraoesophageal
sliding hiatial hernia
- gastrooesophageal junction and the abdominal part of the oesophagus and cardia of stomach move upwards through diaphragmatic hiatus into the thorax
paraoesophageal hiatal hernia
- upward movement of gastric fundus, normal positioned junction (gastric oesophageal)
i. e. not all of it moves up, pouch forms above where It should be
diagnosis of peptic ulcers + treamtnet
1) test for H pylori and then treat
2) treat patients with active suppression therapy
3) endoscopic therapy if bleeding
4) surgical intervention
