🧵 Hernias occur when an organ or tissue protrudes through a weakness in the surrounding muscle or fascia. They often present as a reducible lump that becomes more prominent with coughing or straining, but some carry a high risk of incarceration or strangulation, making early recognition essential. Clinically, the key questions are: Where is the lump? Is it reducible? Is there pain or systemic upset?

🧠 Key Red Flags (Always Assess)

🚨 Severe, persistent pain
🚫 Irreducible, tense hernia
🤢 Vomiting or abdominal distension
🌡️ Fever or systemic toxicity
🩸 Skin erythema over the hernia

📊 Common Types of Hernia – Clinical Comparison

🧠 Type of Hernia	📍 Typical Presentation	🔎 Diagnosis	💊 Management
🧍 Inguinal Hernia	Most common (especially in men) Groin bulge ↑ with standing/coughing Aching or dragging sensation Strangulation → severe pain, vomiting	Clinical exam + cough impulse USS if diagnosis uncertain CT/MRI for recurrent or complex cases	Watchful waiting if asymptomatic Elective repair if symptomatic 🚨 Emergency surgery if strangulated
♀️ Femoral Hernia	More common in women Bulge below inguinal ligament Often small but painful High risk of strangulation	Careful groin exam USS or CT if unclear	⚠️ Early surgical repair recommended Emergency surgery if obstructed/strangulated
👶 Umbilical Hernia	Common in infants & pregnancy Bulge at umbilicus Usually painless	Clinical diagnosis USS rarely required	Observe in children (often closes by age 5) Surgical repair in adults or persistent cases
🔪 Incisional Hernia	At previous surgical scar Bulge increases with strain May be painful or enlarging	Clinical exam CT for size, contents, planning	Usually requires surgical repair Mesh repair reduces recurrence
🔥 Hiatal Hernia	Stomach herniates through diaphragm Heartburn, regurgitation Dysphagia, chest pain	Barium swallow Endoscopy pH studies if reflux prominent	Lifestyle + PPIs first-line Surgery (fundoplication) if refractory
📍 Epigastric Hernia	Midline between umbilicus & xiphisternum Small lump, worse on exertion Often contains fat only	Clinical exam USS or CT if uncertain	Surgical repair if symptomatic Observation if asymptomatic

📚 Teaching Pearls

📍 Location is everything: above vs below the inguinal ligament distinguishes inguinal from femoral.
⚠️ Femoral hernias strangulate early - low threshold for surgery.
🧵 Reducible ≠ harmless - symptoms and progression matter.
🚨 Pain + irreducibility + vomiting = strangulation until proven otherwise.
🩺 Imaging supports diagnosis - but clinical exam is key.
