Gastroenterology Symptoms: When to See a GI Specialist

Gastrointestinal symptoms span a wide spectrum. Persistent or alarming signs warrant evaluation by a gastroenterologist.

Common Symptoms

• Abdominal pain / discomfort (localized, diffuse, cramping, burning)
• Nausea, vomiting (including hematemesis / coffee-ground)
• Diarrhea (acute, chronic, bloody, nocturnal)
• Constipation (infrequent, hard, incomplete evacuation)
• Bloating, distension, excessive gas
• Heartburn, regurgitation, dysphagia, odynophagia
• Rectal bleeding (hematochezia, melena)
• Unintentional weight loss
• Fatigue (may indicate anemia, malabsorption, inflammation)
• Appetite changes, early satiety

Red Flags – Urgent Evaluation

• Age >50 with new symptoms (colorectal cancer screening).
• Family history of GI cancer, IBD, celiac.
• Nocturnal diarrhea, bleeding, weight loss.
• Dysphagia (progressive).
• Iron-deficiency anemia (unexplained).
• Jaundice, dark urine, pale stools.

Diagnostic Tools

• Labs: CBC, CMP, inflammatory markers, celiac serology, stool studies (calprotectin, culture, O&P, fat).
• Endoscopy: EGD, colonoscopy, enteroscopy, capsule endoscopy.
• Imaging: CT/MR enterography, ultrasound, MRI/MRCP.
• Functional: Breath tests (SIBO, lactose), manometry, pH/impedance.

Don't self-diagnose. Many serious conditions mimic benign ones. Early GI consultation improves outcomes.
