B. SECONDARY HYPERACIDITY
I. REFLUX OESOPHAGITIS
The disorder may be defined as damage to the
esophageal mucosa due to reflux of gastric contents.
Etiology:
Increased reflux of gastric contents into the
esophagus from reduced pressure in the lower
oesophageal sphincter and an increased number of
transient relaxation of the sphincter are the main
factors in the development of reflux esophagitis.
Clinical Features / Symptoms:
1.
Heartburn: This is a sensation of burning or burning
pain located high in the epigastria or behind the
lower end of the sternum often radiating upwards
behind the sternum. It occurs after meals and is
characteristically brought on by lifting or straining
due to an increase in the abdominal pressure.
Heartburn may also occur on lying down in bed at
night, preventing sleep or awakening the patient
several hours after the onset of sleep.
It is sometimes precipitated immediately by acid food
or drink – tomatoes, orange, cola, and alcohol.
2.
Painful Dysphagia: The usual cause is the bolus of
food passing through an inflamed segment of esophagus.
3.
Regurgitation of gastric contents into the mouth may
occur during bending, after large meal or at night.
The patient becomes aware of the regurgitation because
of a bitter taste in the mouth.
4.
Sore throat, Globus sensation (‘lump in throat’),
and hoarseness are other consequences.
Management:
·
Weight reduction
·
Stopping cigarette smoking
·
Meals should be of small volume
·
Alcohol, fatty food, and caffeine should be avoided
·
No snacks must be taken after evening meal to prevent
nocturnal regurgitation
·
Heavy stooping or bending at the waist should be
avoided especially after meals
·
Head in the bed should be elevated by 15 cm.
II. PEPTIC ULCER
The term ‘peptic ulcer’ refers to an ulcer in the
lower esophagus, stomach, or duodenum.
Etiology:
Following factors play a role
·
Heredity
·
Helicobacter pylori
·
NSAID’s
·
Smoking
·
Chronic stress
·
Alcohol
·
Corticosteroids
·
Duodenogastric reflux of bile.
Pathology:
An ulcer forms when there is an imbalance between
aggressive forces, i.e., the digestive power of acid
and pepsin, and defensive factors i.e., the ability of
the gastric and duodenal mucosa to resist this
digestive power. However, in the majority of patients
acid secretion is within normal limits or is
moderately raised. In these individuals, damage to the
gastric mucosal barrier is necessary to facilitate the
damaging effect of acid and pepsin. The initial damage
results from Helicobacter pylori, NSAID’s, and
smoking.
Clinical Features / Symptoms:
Epigastric pain:
Pain is referred to the epigastrium and is often so
sharply localized that the patient can indicate its
site with two or three fingers-the ‘pointing sign’.
Hunger pain:
Pain occurs intermittently during the day, often when
the stomach is empty, so that the patient identifies
it as ‘hunger pain’ and obtains relief by eating.
Night pain:
Pain wakes the patient from sleep and may be relieved
by food, a drink of milk, or antacids; this symptom
when present is virtually pathognomonic for ulcer.
Water brash:
This is a sudden filling of mouth with saliva which is
produced as a reflex response to a variety of symptoms
from the upper GIT, e.g., peptic ulcer pain
Heartburn
Loss of appetite
Vomiting |
