### 1. Potential Differential Diagnoses

For a 13-year-old male with sudden, severe upper abdominal pain, consider:

- **Acute gastritis or peptic ulcer disease** (with or without perforation)
- **Acute pancreatitis**
- **Biliary colic or cholecystitis** (less common in males, but possible)
- **Gastroenteritis**
- **Splenic pathology** (e.g., infarct, rupture—rare but possible)
- **Gastric volvulus**
- **Esophageal rupture (Boerhaave syndrome)** (rare, but severe)
- **Diabetic ketoacidosis** (if diabetic)
- **Referred pain from lower lobe pneumonia**
- **Musculoskeletal pain** (if history of trauma)
- **Toxic ingestion** (if history suggests)
- **Intestinal obstruction or volvulus**

### 2. Recommended Diagnostic Tests

- **Physical examination**: Assess for peritonitis, guarding, rebound tenderness, Murphy’s sign, etc.
- **Vital signs**: Assess for fever, tachycardia, hypotension, tachypnea
- **Laboratory tests**:
  - CBC, electrolytes, renal function, liver function tests
  - Amylase/lipase (for pancreatitis)
  - Urinalysis
  - Blood glucose
  - Inflammatory markers (CRP, ESR)
- **Imaging**:
  - Abdominal ultrasound (first-line, especially for biliary or pancreatic pathology)
  - Abdominal X-ray (look for free air, obstruction)
  - Consider CT abdomen if diagnosis remains unclear or if severe findings
- **Other**:
  - EKG (if cardiac cause suspected)
  - Stool studies (if diarrhea present)

### 3. Urgency Level

**High**  
- Sudden, severe abdominal pain in a child is always concerning and warrants urgent evaluation to rule out surgical or life-threatening causes (e.g., perforated ulcer, pancreatitis, volvulus, splenic rupture).

---

### 4. Key Observations and Clinical Notes

- Onset, duration, and character of pain (sudden and severe is worrisome)
- Associated symptoms: vomiting, fever, jaundice, diarrhea, chest pain, shortness of breath
- Past medical history (not provided)
- Recent trauma, ingestion, or illness
- Family history of GI or metabolic disorders
- Physical exam findings: tenderness, guarding, rigidity, distension, bowel sounds

---

### 5. Red Flags to Watch For

- Signs of peritonitis (rebound tenderness, guarding, rigidity)
- Hemodynamic instability (hypotension, tachycardia, shock)
- Persistent vomiting (especially bilious or bloody)
- Signs of GI bleeding (hematemesis, melena)
- Altered mental status
- Severe dehydration
- Jaundice
