TOPIC 1. Dysphagia, Upper GI Bleeding & Vomiting Across the Lifespan

One connected view of symptoms, mechanisms, diagnostic clues and safe clinical decisions.

1. THE TOPIC IN ONE CONNECTED FLOW

Difficulty swallowing, gastrointestinal bleeding and persistent vomiting are different presentations, but the same clinical reasoning connects them. Identify the affected function, recognize danger, select investigations that answer the clinical question, and treat the cause. Age and pregnancy change the likely diagnosis and the urgency of intervention.

Presenting symptom

Dysphagia / hematemesis or melena / persistent vomiting

→

Core disturbance

Obstruction or poor motility / mucosal or variceal hemorrhage / reflux or gastric–intestinal obstruction

→

Clinical pattern

Solids vs liquids / perfusion and bleeding signs / bilious vs nonbilious emesis, growth, gestation

→

Targeted assessment

Focused examination, CBC and electrolytes where indicated; endoscopy, manometry or ultrasound according to suspected cause

→

Management

Stabilize first if ill; relieve obstruction, secure hemostasis, rehydrate, treat vomiting and its cause

→

Safer outcome

Prevent aspiration, shock, ischemic bowel, electrolyte injury and nutritional deterioration

2. KEY CLINICAL CONNECTIONS

Dysphagia: pattern directs the test

Solids first, then liquids → mechanical narrowing → upper GI endoscopy; suspicious lesion → biopsy and urgent assessment.
Solids and liquids from onset → motility disorder → manometry after structural disease is excluded.
Coughing as swallowing begins → oropharyngeal dysfunction → aspiration assessment.

Upper GI bleed: instability changes priority

Hematemesis or melena + tachycardia/hypotension → possible major blood loss → airway/circulation assessment and resuscitation before endoscopy.
Ulcer bleeding → endoscopic hemostasis and acid suppression; portal hypertension with variceal bleeding → vasoactive treatment, antibiotics in cirrhosis and endoscopic banding.

Vomiting: age and danger signs decide urgency

Young infant + projectile nonbilious vomiting → pyloric stenosis → ultrasound; gastric acid loss → hypochloremic metabolic alkalosis → correct fluids/electrolytes before surgery.
Neonate + bilious vomiting → possible intestinal obstruction/volvulus → urgent surgical assessment.
Early pregnancy + persistent disabling vomiting → dehydration/electrolyte deficits → fluids, thiamine when indicated, antiemetics and obstetric follow-up.

3. AIM HIGH-YIELD INTEGRATION REVIEW

⭐ Progressive solid-food dysphagia + weight loss → possible malignant narrowing → urgent endoscopy and biopsy.
Dysphagia to solids and liquids from the beginning → consider motility dysfunction → manometry defines the disorder after structural causes are excluded.
⭐ Hematemesis with shock features → ongoing circulatory threat → resuscitation takes priority over definitive endoscopic treatment.
Peptic ulcer versus variceal bleeding → different mechanisms → acid suppression/endoscopic ulcer hemostasis versus portal-pressure-directed therapy and variceal banding.
⭐ Projectile nonbilious vomiting in early infancy → pyloric outlet obstruction → ultrasound diagnosis; acid loss explains alkalosis and the need for preoperative correction.
⭐ Bilious neonatal vomiting → possible obstruction with threatened bowel perfusion → nothing orally, stabilization and emergency surgical assessment.
Thriving infant with small regurgitations → likely physiological reflux; poor growth or feeding-related coughing → investigate disease or aspiration risk.
Severe early-pregnancy vomiting + poor intake → dehydration, electrolyte and thiamine depletion → rehydration, appropriate antiemetics, nutritional attention and clear return precautions.
