Hiatal Hernia & Paraesophageal Hernia
Videos
Overview
A hiatal hernia is the abnormal protrusion of an abdominal organ — most often the stomach — through the esophageal hiatus of the diaphragm into the chest (Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022). It is extremely common, reported in roughly 10–50% of adults depending on how it is defined and detected, and is present in up to 94% of patients with reflux esophagitis and about 40% of patients with severe obesity (Bougleux Gomes et al., JOMI, 2023; Howell et al., Scientific Reports, 2020).
Hernias are classified anatomically into four types, and the distinction drives everything about management (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018):
• Type I (sliding) — the esophagogastric junction (EGJ) slides up above the diaphragm. This accounts for roughly 90–95% of all hiatal hernias and is the type most strongly linked to GERD (Bougleux Gomes et al., JOMI, 2023; Howell et al., Scientific Reports, 2020).
• Type II — the EGJ stays in its normal position, but part of the gastric fundus rolls up alongside the esophagus (a true paraesophageal hernia) (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018).
• Type III (mixed) — the most common paraesophageal type, combining features of I and II: both the EGJ and the fundus are displaced into the chest (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018).
• Type IV — a non-gastric organ (colon, spleen, small bowel, or pancreas) herniates alongside the stomach (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018).
Types II–IV are grouped together as paraesophageal hernias (PEH) and behave very differently from sliding hernias — their danger is mechanical (obstruction, twisting, strangulation) rather than purely reflux-related (Andolfi et al., Journal of Laparoendoscopic & Advanced Surgical Techniques, 2016). Small, asymptomatic sliding hernias need no treatment; symptomatic hernias and paraesophageal hernias are where evaluation and, often, surgery come in (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018).
When the top of the stomach rolls up into the chest beside the esophagus, the hernia is called a paraesophageal hernia. Because these hernias can twist, bleed or obstruct, they are covered in detail on our paraesophageal hernia page.
A hiatal hernia develops when the structures that normally anchor the EGJ in the abdomen — the phrenoesophageal membrane and the diaphragmatic crura — weaken or stretch, while the natural pressure difference between the abdomen and chest pulls the stomach upward (Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022). Two mechanisms are generally accepted: (1) long-standing GERD causes esophageal scarring and shortening that pulls the EGJ upward, and (2) chronically increased intra-abdominal pressure combined with a predisposed, lax hiatus pushes the stomach into the chest (D'Urbano et al., Journal of Laparoendoscopic & Advanced Surgical Techniques, 2023). With age, the phrenoesophageal ligament naturally loosens, which is why prevalence rises over the decades (D'Urbano et al., Journal of Laparoendoscopic & Advanced Surgical Techniques, 2023). Congenital hiatal defects are the usual cause in children (D'Urbano et al., Journal of Laparoendoscopic & Advanced Surgical Techniques, 2023).
Risk Factors
- Older age — an independent risk factor, reflecting progressive ligamentous laxity (Dong et al., Surgical Endoscopy, 2025; D'Urbano et al., Journal of Laparoendoscopic & Advanced Surgical Techniques, 2023).
- Male sex — identified as an independent risk factor in a large retrospective analysis (Dong et al., Surgical Endoscopy, 2025).
- Central/abdominal obesity — increased waist–hip ratio and trunk fat show strong genetic associations with hiatal hernia, more so than BMI alone (Dong et al., Surgical Endoscopy, 2025).
- GERD — both a cause and a consequence; about 45% of GERD patients have a hiatal hernia (Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022).
- Chronically raised intra-abdominal pressure — heavy physical labor (an independent risk factor), pregnancy, and repeated vomiting (Dong et al., Surgical Endoscopy, 2025; Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022).
- Thoracic skeletal changes in the elderly — kyphosis, scoliosis, and osteoporosis that alter chest geometry (D'Urbano et al., Journal of Laparoendoscopic & Advanced Surgical Techniques, 2023).
How It Affects the Body
The effect depends on the type of hernia. A sliding (type I) hernia disrupts the antireflux barrier at the EGJ — it separates the lower esophageal sphincter from the supporting crural diaphragm, delays acid clearance, and increases esophageal acid exposure, which is why sliding hernias drive reflux, esophagitis, and complicated GERD (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018). This mechanical barrier failure is also why some patients' heartburn responds to acid suppression but their regurgitation does not (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018).
A paraesophageal hernia acts mechanically: the herniated fundus can twist on itself, compress the esophagus, and obstruct the stomach, while the portion of stomach repeatedly sliding through the hiatus develops shear-related linear ulcers (Cameron lesions) that bleed chronically (Andolfi et al., Journal of Laparoendoscopic & Advanced Surgical Techniques, 2016). Large hernias also occupy thoracic space, which can compress the lungs or even the left atrium and produce shortness of breath (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018).
Complications
- Complicated GERD — reflux esophagitis (graded A–D by the Los Angeles classification), peptic stricture, Schatzki ring, and Barrett's esophagus, which is found in association with the large majority of long-segment Barrett's cases (Maret-Ouda et al., JAMA, 2020; Richter & Rubenstein, Gastroenterology, 2018; Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022).
- Iron-deficiency anemia — from Cameron lesions/chronic occult bleeding; seen in up to 50% of patients with a paraesophageal hernia, and resolving after repair in roughly 72–90% of cases (Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022; Andolfi et al., Journal of Laparoendoscopic & Advanced Surgical Techniques, 2016).
- Gastric volvulus, obstruction, incarceration, and strangulation — the feared mechanical emergencies of a PEH; the risk of an asymptomatic PEH becoming symptomatic is about 14% per year, and acute strangulation/perforation carries mortality as high as 50% (Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022).
- Respiratory compromise — exertional dyspnea or recurrent aspiration pneumonia from thoracic displacement of the stomach (Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022).
- Esophageal adenocarcinoma — the most feared long-term consequence of the reflux–Barrett's pathway (Richter & Rubenstein, Gastroenterology, 2018).
Symptoms and Signs
Many hiatal hernias are asymptomatic and found incidentally on endoscopy or imaging (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018). When symptoms occur, sliding hernias typically produce reflux symptoms — heartburn, regurgitation, and dysphagia (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018). Paraesophageal hernias more often cause mechanical and extra-esophageal symptoms:
• Postprandial fullness, early satiety, nausea, and epigastric or substernal pain, sometimes relieved by vomiting (Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022).
• Dysphagia and regurgitation from EGJ obstruction or volvulus (Bougleux Gomes et al., JOMI, 2023).
• Fatigue from iron-deficiency anemia (occult bleeding) (Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022).
• Breathlessness, chest pain, or recurrent respiratory infections from thoracic compression/aspiration (Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022).
Sudden severe chest or upper-abdominal pain with retching and inability to vomit (Borchardt's triad) suggests acute gastric volvulus and is a surgical emergency (Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022).
Diagnosis
A hiatal hernia can be identified by several complementary tests, each with strengths (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018):
- Upper endoscopy (EGD) — most hernias are found here; it best assesses mucosal consequences (esophagitis, Barrett's, Cameron lesions) but tends to underestimate hernia size and has poor inter-observer agreement (Rohof & Smout, The Esophagus, 2021; Philpott & Sweis, Current Gastroenterology Reports, 2017).
- Barium esophagram — provides excellent anatomic and bolus-transit information and is particularly good for defining paraesophageal anatomy; a crural-to-B-ring distance of ≥2 cm is a common radiographic definition (Rohof & Smout, The Esophagus, 2021; Philpott & Sweis, Current Gastroenterology Reports, 2017).
- High-resolution esophageal manometry (HRM) — considered the most sensitive and specific test for detecting and sizing a hernia (sensitivity ~92%, specificity ~93%), and it assesses esophageal motility, which is essential before any antireflux operation (Rohof & Smout, The Esophagus, 2021; Gyawali et al., ACG Guidelines on Esophageal Physiologic Testing, 2020).
- CT scan — valuable for type IV hernias and suspected volvulus or obstruction (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018).
- Ambulatory pH (or pH-impedance) monitoring — used to objectively document pathologic reflux before repairing a type I hernia for GERD (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018).
Differential Diagnosis
Symptoms overlap with several foregut and non-GI conditions, including GERD without a hernia, achalasia and other esophageal motility disorders, peptic ulcer disease, gastroparesis, functional dyspepsia, eosinophilic esophagitis, and esophageal or gastric malignancy; the mechanical and chest symptoms of a large PEH can also mimic cardiac or pulmonary disease (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018; Andolfi et al., Journal of Laparoendoscopic & Advanced Surgical Techniques, 2016). Objective testing (endoscopy, imaging, manometry, pH monitoring) distinguishes among these (Gyawali et al., ACG Guidelines on Esophageal Physiologic Testing, 2020).
Lifestyle Modifications
For hernias driving reflux, the same measures that help GERD reduce symptoms, with the strongest evidence for weight loss (especially reducing abdominal/visceral fat), elevating the head of the bed, and avoiding meals within about 3 hours of lying down (Fass, New England Journal of Medicine, 2022; Desai et al., ASGE GERD Guideline, 2025). Additional measures include smoking cessation, staying upright during and after meals, eating smaller meals, and limiting individual trigger foods (alcohol, chocolate, peppermint, caffeine, carbonated and high-fat or acidic foods) (Roman et al., Yamada's Textbook of Gastroenterology, 2022; Katz et al., ACG GERD Guideline, 2022). In a large prospective cohort, women adhering to several antireflux lifestyle factors had roughly half the risk of reflux symptoms (Fass, New England Journal of Medicine, 2022). These measures control symptoms but do not repair the hernia itself (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018).
Treatment Options
Treatment is tailored to hernia type and symptoms (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018):
- Observation — small, asymptomatic sliding hernias need no treatment beyond noting their presence (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018).
- Medical therapy — proton pump inhibitors are the foundation for a hernia causing reflux; they control heartburn well but are less effective for regurgitation driven by mechanical barrier failure (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018).
- Surgical repair (the only treatment that repairs the hernia itself) — indicated for symptomatic type I hernias with reflux not controlled by medication (ideally after objective pH testing), for all symptomatic type II/III hernias, for all type IV hernias, and urgently for acute complications (volvulus, obstruction, bleeding, strangulation) (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018). Repair reduces the hernia, excises the sac, closes the crura (with selective mesh), and adds a fundoplication to control reflux and anchor the stomach (Bougleux Gomes et al., JOMI, 2023). For asymptomatic/minimally symptomatic paraesophageal hernias in fit patients, elective repair is now suggested over watchful waiting, whereas conservative management is recommended for frail patients (Markar et al., Surgical Endoscopy [EAES Guideline], 2023).
When to See a Doctor
Anyone with persistent or frequent heartburn, regurgitation, or difficulty swallowing — or an incidental finding of a large hiatal/paraesophageal hernia — should be evaluated, because symptoms that don't respond to standard GERD therapy (especially regurgitation or dysphagia) may indicate a mechanical hernia that warrants surgical assessment (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018). Unexplained iron-deficiency anemia, early satiety, postprandial chest/upper-abdominal pain, or breathlessness in a patient with a known hernia also merit prompt evaluation (Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022).
When to Seek Treatment
Seek emergency care for sudden severe chest or upper-abdominal pain, persistent vomiting or inability to vomit/retching, or inability to swallow saliva — these can signal gastric volvulus, obstruction, or strangulation, which are surgical emergencies with high mortality if untreated (Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022). Non-emergent but important reasons to pursue definitive treatment include reflux or regurgitation inadequately controlled on medication, progressive dysphagia, recurrent aspiration, and anemia attributable to the hernia (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018; Andolfi et al., Journal of Laparoendoscopic & Advanced Surgical Techniques, 2016).
Long‑Term Outlook
With appropriate treatment, long-term quality of life is excellent, though patients should understand that recurrence is the main long-term issue after repair — up to about 48% for large (>5 cm) hernias, versus under 25% at 3 years for hernias smaller than 5 cm, with most recurrences small and asymptomatic (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018). Some patients need ongoing acid-suppressing medication, occasional endoscopic dilation for dysphagia, or—rarely—revisional surgery (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018). Follow-up is driven by symptoms, and patients with Barrett's esophagus require continued endoscopic surveillance regardless of hernia repair (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018).

Prognosis
Most hiatal hernias are small, stable, and never cause problems (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018). Symptomatic and paraesophageal hernias respond very well to minimally invasive repair, with durable symptom relief, high patient satisfaction, and resolution of hernia-related anemia in most patients (Andolfi et al., Journal of Laparoendoscopic & Advanced Surgical Techniques, 2016; Howell et al., Scientific Reports, 2020). Untreated paraesophageal hernias tend to enlarge over time, with roughly a 14% annual risk of becoming symptomatic and a real—if uncommon—risk of acute, life-threatening volvulus (Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022).
Why Choose Dr. de la Cruz‑Muñoz
Hiatal and paraesophageal hernias sit at the intersection of reflux disease and complex foregut anatomy, and outcomes are strongly tied to surgeon and center experience (Bougleux Gomes et al., JOMI, 2023). As a board-certified surgeon with advanced expertise in minimally invasive and robotic foregut surgery, Dr. Nestor de la Cruz-Muñoz, MD, FACS, DABOM emphasizes the complete, guideline-concordant workup these hernias require — upper endoscopy, barium esophagram, high-resolution manometry, and, when GERD is the indication, objective pH testing — before recommending treatment (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018; Gyawali et al., ACG Guidelines on Esophageal Physiologic Testing, 2020). He distinguishes carefully between small sliding hernias that need only medical management and paraesophageal hernias that warrant repair, and performs minimally invasive repair with full sac excision, tension-free crural closure, and an individualized fundoplication (Markar et al., Surgical Endoscopy [EAES Guideline], 2023; Bougleux Gomes et al., JOMI, 2023). Patients receive candid counseling about when to simply observe, when to operate, and the realistic long-term outlook including recurrence risk.
Dr. de la Cruz-Muñoz's team has published research comparing upper GI studies and symptom questionnaires with the intraoperative diagnosis of hiatal hernia during sleeve gastrectomy (Ribieras et al., Surgery for Obesity and Related Diseases, 2023), informing how hiatal hernias are identified and repaired at the time of bariatric surgery.
Hiatal hernia repair combines two areas Dr. de la Cruz-Muñoz knows well: foregut and hernia surgery. In over 25 years of practice he has performed over 15,000 minimally invasive procedures, which also include gallbladder, abdominal and bariatric operations.

FAQ
A hiatal hernia will not disappear or heal on its own — the diaphragm opening does not close back down without an operation, so surgery is the only way to actually repair the hernia (Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022). That said, most hiatal hernias never need surgery. The large majority are small, sliding (type I) hernias, and their symptoms are controlled very effectively without repairing the hernia itself — using proton pump inhibitors plus lifestyle measures such as weight loss, elevating the head of the bed, avoiding meals within 2–3 hours of lying down, and limiting trigger foods (Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018; Sanderson & Escudier, Burket's Oral Medicine, 2021). Surgery becomes the treatment of choice when medication and lifestyle changes fail to control symptoms (especially regurgitation or difficulty swallowing), when a patient prefers not to take lifelong medication, or for larger paraesophageal hernias at risk of mechanical complications (Gonda & Krikhely, Yamada's Textbook of Gastroenterology, 2022; Callaway & Vaezi, Clinical Gastroenterology and Hepatology, 2018).
Yes. Because the esophagus and stomach sit directly behind the heart and lungs, a hiatal hernia can produce chest pain that closely mimics a heart attack, and gastrointestinal causes account for roughly 10–20% of chest pain in outpatients (Anderson et al., Journal of the American College of Cardiology, 2022; Sanderson & Escudier, Burket's Oral Medicine, 2021). Large hernias in particular can cause shortness of breath through several mechanisms — compression of the lungs, reduced lung volumes, obstruction of blood flow into the heart, and microaspiration — and this cardiorespiratory connection has historically been underappreciated (Mahendravarman et al., ANZ Journal of Surgery, 2026). Heart racing and palpitations can also occur, and when they appear suddenly alongside severe chest/abdominal pain, severe vomiting, or inability to pass anything, they may signal that the stomach has twisted or lost its blood supply (volvulus/strangulation) — a medical emergency requiring immediate care (Baiu & Lau, JAMA, 2019). Any new chest pain should be evaluated to rule out a cardiac cause first, but a known large hernia is a recognized and often reversible contributor to these symptoms (Mahendravarman et al., ANZ Journal of Surgery, 2026).
Often, yes, for the right patient. In migration patients who are not bypass candidates, hernia repair with posterior cruroplasty alone has achieved up to 72% reflux resolution (Vosburg et al., American Society for Metabolic and Bariatric Surgery, 2026). Adding a ligamentum teres cardiopexy helped 81% of patients reduce or stop acid medication at one year (Mackey et al., Surgical Endoscopy, 2023). This approach suits patients with good weight loss, a smaller hernia, and no severe esophageal damage. Conversion to bypass is usually better if you have weight regain, Barrett's esophagus, severe esophagitis, or a failed earlier repair (Sabry et al., Journal of Laparoendoscopic & Advanced Surgical Techniques, 2022; Kermansaravi et al., Surgical Endoscopy, 2023).
Yes. The top of the sleeve can slide up through the diaphragm into the chest. This is called intrathoracic sleeve migration, a type of hiatal hernia. Most cases develop months to years after surgery and cause reflux, regurgitation, food intolerance, or trouble swallowing (Aloulou et al., Obesity Surgery, 2024). It is more common than once thought: nearly half of patients converted to bypass for reflux in one series had a migrated sleeve (Crozet et al., Obesity Surgery, 2024). A CT scan, contrast study, and endoscopy confirm the diagnosis (Crozet et al., Obesity Surgery, 2024).
It depends on whether dysplasia is present. For ordinary non-dysplastic Barrett's esophagus, acid-suppression alone does not reliably reverse it — long-term proton pump inhibitor (PPI) therapy may shrink the segment slightly and produce scattered islands of normal squamous lining, but complete regression is rare (Alkhayyat et al., Therapeutic Advances in Gastroenterology, 2020; Spechler et al., Yamada's Textbook of Gastroenterology, 2022). The goals of treatment for non-dysplastic disease are therefore reflux control and reducing the small risk of progression, not elimination of the Barrett's tissue itself, and endoscopic removal is not recommended at this stage (Fitzgerald, New England Journal of Medicine, 2026). When dysplasia or early cancer develops, Barrett's can effectively be eradicated with endoscopic eradication therapy — endoscopic resection of any visible lesion followed by radiofrequency ablation — which resolves intestinal metaplasia in up to ~77% and dysplasia in ~86% of cases and lowers the risk of progression (Rustgi & El-Serag, New England Journal of Medicine, 2014). Even after successful eradication, recurrence is possible, so ongoing surveillance remains necessary (Rustgi & El-Serag, New England Journal of Medicine, 2014). There is also evidence that antireflux surgery (fundoplication) achieves histologic regression more often than medical therapy, because it controls both acid and bile reflux (Wilson et al., Surgical Endoscopy, 2022).
Most people with Barrett's esophagus never develop esophageal cancer. For non-dysplastic Barrett's, the annual risk of progressing to esophageal adenocarcinoma is only about 0.2–0.5% per year (roughly 1 in 200 to 1 in 500 patients each year), and the risk is lower still for short segments under 3 cm (about 0.06% per year) than for longer segments (about 0.31% per year) (Sharma, JAMA, 2022; Spechler et al., Yamada's Textbook of Gastroenterology, 2022). The risk rises substantially only if dysplasia develops — roughly 0.5–0.7% per year with low-grade dysplasia and 5–7% per year with high-grade dysplasia — which is precisely why surveillance endoscopy exists: to catch that change early when it is curable (Rustgi & El-Serag, New England Journal of Medicine, 2014; Fitzgerald, New England Journal of Medicine, 2026). Several steps may lower risk: daily PPI therapy is suggested to reduce neoplastic progression (AGA Guideline, Wani et al., 2025); smoking cessation and weight loss are recommended, since smoking, male sex, older age, and central obesity all increase progression risk (Sharma, JAMA, 2022; Wani et al., AGA Guideline, 2025); and statins have been associated with roughly a 47% lower odds of progression in observational data, though this is not yet guideline-endorsed as chemoprevention (Ko et al., Diseases of the Esophagus, 2025). Aspirin alone has not shown a clear independent benefit (AGA Guideline, Wani et al., 2025).
Hiatal hernia repair is usually done laparoscopically or robotically. The surgeon returns the stomach to the abdomen, removes the hernia sac, frees the esophagus so enough of it sits below the diaphragm without tension, and closes the enlarged opening in the diaphragm with sutures, sometimes reinforced with mesh. A fundoplication (Nissen or Toupet) is usually added to prevent reflux, or a gastric bypass in patients with obesity. Most patients go home within one to two days.
Endoscopy is very useful — it shows the position of the stomach and esophagus, measures the hernia and checks for esophagitis, Barrett's esophagus and Cameron ulcers. But it can underestimate or miss hiatal hernias, especially small or intermittent ones, and imaging and symptom questionnaires can be inaccurate too (Ribieras et al., Surgery for Obesity and Related Diseases, 2023). A barium swallow or CT scan adds anatomic detail, and the final size is often confirmed during surgery.
No. Mesh is used selectively based on the size of the hernia and the quality of the tissue. The foundation of hiatal hernia repair is closing the diaphragm opening with sutures and getting enough esophagus into the abdomen without tension. Mesh reinforcement may reduce early recurrence in large hernias, but long-term benefits are less clear (Oelschlager et al., Journal of the American College of Surgeons, 2011), so the decision is individualized.
