Dysphagia
Dysphagia
Difficulty swallowing, possibly due to muscular issues, obstructions like tumors, or neurological problems such as stroke.
Acid Reflux
Acid Reflux
Weak sphincter between the esophagus and stomach leads to acid reflux, causing irritation and pain (heartburn).

Study Notes
- Dysphagia is difficulty swallowing, potentially stemming from esophageal musculature issues, obstructions like tumors especially squamous cell carcinoma higher up or adenocarcinomas lower down, or neurological events such as a stroke.
Acid Reflux
- A weak sphincter between the esophagus and stomach allows acid to reflux, causing irritation, pain, and heartburn.
- Chronic oesophagitis results from persistent acidic gastric content reflux.
Barrett’s Oesophagus
- Prolonged acid reflux leads to this condition.
- Abnormal columnar epithelium replaces the normal stratified squamous epithelium in the distal esophagus.
- It is considered a premalignant condition.
Oesophageal Varices
- Portal venous system overload, often due to cirrhosis, diverts blood to the esophagus through connecting vessels.
- This causes submucosal veins in the lower esophagus to dilate.
Gastritis
- It involves gastric tissue inflammation, potentially leading to mucosa damage or erosion.
- Persistent erosion results in ulceration, which can hemorrhage, perforate, heal via fibrosis, or develop into malignancy.
- Forms include erosive and chronic gastritis.
Peptic Ulcer
- Formation of an ulcer in the stomach or duodenum occurs due to disrupted nervous and hormonal regulation within the gastroduodenal system, and is a chronic recurrent disease
Common Intestine Disorders
- Duodenal ulcers arise from unprotective mucosa reacting to acidic chyme.
Coeliac Disease
- It damages mucosal villi, leading to malabsorption and subsequent diarrhea.
Jaundice
- The liver's inability to excrete bilirubin, a hemoglobin breakdown product, triggers it to accumulate in the blood.
- Pre-hepatic jaundice is caused by excess hemoglobin breakdown.
- Post-hepatic or obstructive jaundice results from bile duct obstruction, bile back-up, and consequent liver damage.
Gallstones
- These form from precipitated bile acids and cholesterol in the gallbladder.
- Gallstones are often asymptomatic, they can cause painful biliary colic if they move within the gallbladder, or obstruct biliary outflow.
- Pancreatic tumors might also obstruct outflow.
Malabsorption
- Intestinal absorption can be affected by several conditions.
