A twisted stomach in humans, known medically as gastric volvulus, occurs when the stomach rotates more than 180 degrees on itself, creating a closed-loop obstruction that traps food, fluid, and gas inside. The most common cause in adults is a defect in the diaphragm, usually a paraesophageal or hiatal hernia, that gives the stomach enough room to flip. Less frequently, the condition arises because the ligaments anchoring the stomach to surrounding organs are too loose, allowing it to move freely and rotate on its own. Though rare, gastric volvulus is a genuine surgical emergency when it strikes acutely, and its causes are more varied than most people realize.
How the Stomach Normally Stays Put
Your stomach is not just floating loosely inside your abdomen. It is tethered in place by a set of ligaments that connect it to the spleen, the liver, the diaphragm, and the colon. These fibrous bands keep the stomach oriented correctly even when you bend, twist your body, or fill it with a large meal. When these anchoring ligaments are intact and taut, the stomach has very limited freedom of movement.
Problems begin when those ligaments become lax or fail to develop properly. Looseness in these peritoneal attachments allows the stomach to become hypermobile, and a hypermobile stomach is one that can rotate on itself.1PubMed. Abdominal twists and turns: part I, gastrointestinal tract torsions with pathologic correlation This ligamentous laxity can happen with aging, after trauma, or simply as an anatomical variation someone is born with. In cases where no other structural abnormality is found, doctors classify the volvulus as “idiopathic,” meaning the loose ligaments alone are the culprit.2Journal of Education and Teaching in Emergency Medicine (JETem). Gastric Volvulus
Diaphragmatic Hernias and the Adult Stomach
By far the most common trigger for gastric volvulus in adults is a paraesophageal or hiatal hernia. In this situation, part of the stomach pushes upward through an opening in the diaphragm (the muscular sheet separating the chest from the abdomen). Once a portion of the stomach has migrated into the chest cavity, it loses the stabilizing support of the surrounding abdominal organs and the diaphragm itself. That freed-up portion can then rotate, sometimes dramatically.
A paraesophageal hernia is distinct from the more common sliding hiatal hernia most people associate with acid reflux. In a paraesophageal hernia, the stomach rolls up alongside the esophagus rather than simply sliding upward. This rolling creates exactly the kind of abnormal positioning that can lead to a twist. Case reports consistently show patients presenting with gastric volvulus on a background of large paraesophageal hernias, sometimes in combination with other abdominal wall defects like incisional hernias from prior surgery.3PubMed Central. Two Hernias, One Patient: A Case of Organoaxial Gastric Volvulus in a Paraesophageal Hernia With an Incisional Hernia A systematic review of acute gastric volvulus complicating paraesophageal hernias found that this combination continues to carry a poor prognosis despite advances in surgical technique.4PubMed Central. Acute paraesophageal hernia with gastric volvulus. Results of surgical treatment: a systematic review and meta-analysis
Because paraesophageal hernias tend to enlarge with age, older adults are the group most commonly affected by gastric volvulus. The diaphragm weakens over decades, the hiatal opening stretches, and more of the stomach gradually slides upward. A large meal or a spike in intra-abdominal pressure from coughing, straining, or bending can then be enough to tip the balance and cause a rotation.
The Two Main Ways the Stomach Twists
Not all gastric volvulus looks the same. The stomach can twist along different axes, and the type of twist affects both how the condition presents and how surgeons approach it.
- Organoaxial: The stomach flips along its long axis, so the greater curvature (the bottom curve) ends up on top and the lesser curvature drops below. On a CT scan the stomach appears to have a horizontal lie. This is the most common type and is strongly associated with diaphragmatic hernias.5PubMed Central. Gastric organoaxial volvulus: A lethal twist and a rare cause of acute abdomen
- Mesenteroaxial: The stomach rotates around a short axis running from the middle of its lesser curvature outward. The lower portion of the stomach (the antrum) flips upward above where the esophagus enters, giving the stomach a vertical lie on imaging. This type is less common and more often associated with chronic, intermittent symptoms.
- Mixed: A combination of both rotation patterns, which is the least common form.
Distinguishing between these types matters because organoaxial volvulus tends to produce complete obstruction and strangulation more quickly, making it a more urgent surgical emergency. Mesenteroaxial volvulus, by contrast, can sometimes smolder as a chronic condition with repeated episodes of partial twisting and untwisting.
Recognizing the Symptoms
The classic presentation of acute gastric volvulus was described over a century ago and goes by the name Borchardt’s triad. It consists of three symptoms occurring together: severe upper abdominal pain and distension, retching or vomiting that produces little or nothing, and the inability to pass a tube through the nose into the stomach.6PubMed Central. Gastric volvulus, Borchardt’s Triad, and Endoscopy: A Rare Twist That last sign is telling: when the stomach has twisted more than 180 degrees, the passage from the esophagus into the stomach is kinked shut, which is why the retching is “unproductive” and why a tube cannot get through.
This triad has been reported in roughly 70 percent of cases.7Radiology Case Reports. A case report of gastric volvulus, a rare cause of acute abdomen That leaves a significant minority who do not present with the full set, which is one reason gastric volvulus is considered difficult to diagnose on first encounter. The condition can mimic a heart attack, gallbladder disease, or a simple case of food poisoning. An acute presentation often includes nonspecific but severe abdominal pain, nausea, and in more advanced cases, signs that the stomach wall is losing its blood supply.8PubMed Central. Chronic Intrathoracic Gastric Volvulus Management: Could Less Be More?
The tricky part is that chronic gastric volvulus often looks nothing like this. People with a chronic or intermittent twist may experience vague upper abdominal discomfort, early fullness after eating, occasional nausea, and sometimes chest pain, all of which can easily be attributed to reflux or functional dyspepsia. Some patients endure these symptoms for months or years before anyone considers the stomach itself might be rotating intermittently.
How Imaging Confirms the Diagnosis
CT scanning has become the primary tool for identifying gastric volvulus. A study evaluating radiologists’ ability to spot the condition on CT found they were about 90 percent accurate, with substantial agreement between readers.9PubMed Central. CT of Gastric Volvulus: Interobserver Reliability, Radiologists’ Accuracy, and Imaging Findings That is reassuringly high, though the roughly 10 percent miss rate underscores the diagnostic difficulty when the twist is incomplete or the images are ambiguous.
The most reliable CT signs are an abnormal transition point where the lower stomach suddenly narrows without any visible mass or lesion causing it, and the antrum sitting at the same level as or higher than the fundus (the top of the stomach). When both of these findings are present together, sensitivity and specificity for gastric volvulus reach 100 percent in at least one well-designed study.10PubMed. Computed tomography findings of acute gastric volvulus Barium swallow studies and upper endoscopy also play a diagnostic role, particularly when CT findings are equivocal or when the clinical picture strongly suggests the diagnosis despite a less-than-definitive scan.11PubMed Central.

Gastric Volvulus in Children
Although the condition overwhelmingly affects older adults, children are not immune. Pediatric gastric volvulus tends to have different underlying causes than the adult form. Rather than age-related hernias, children more often present with congenital abnormalities: a diaphragm that did not form properly (congenital diaphragmatic hernia), ligaments that never fully developed, or abnormal fixation of the stomach and intestines during fetal development.12PubMed Central. Acute gastric volvulus and congenital diaphragmatic hernia, case report and review
Paraesophageal hiatus hernias are rare in newborns, and when one does occur alongside gastric volvulus the combination is rarer still.13PubMed Central. Congenital paraesophageal hiatus hernia with gastric volvulus When a young child presents with sudden vomiting, abdominal distension, and an inability to tolerate feeds, pediatric surgeons have to keep the diagnosis on their radar. The danger is heightened in children because the stomach wall in a young child may not tolerate the compromised blood flow as long as an adult’s might. In one reported case, a six-year-old developed complete gastric necrosis along with ischemia of surrounding organs due to the extreme pressure buildup inside the twisted stomach.14Journal of Pediatric Surgery Case Reports. Acute gastric volvulus with total gastric necrosis and ischemia of the spleen and kidney
When Previous Surgery Creates the Problem
One of the more frustrating causes of gastric volvulus is prior abdominal surgery. Adhesions, the bands of scar tissue that form after any operation in the abdomen, can create fixed points around which the stomach rotates. Ironically, even operations designed to fix stomach-related issues can set the stage for a twist. A case report described a 53-year-old woman who developed mesenteroaxial gastric volvulus caused by an adhesion that formed after a previous Nissen fundoplication, a surgery originally performed to treat severe acid reflux.15PubMed Central. Gastric Volvulus After Nissen Fundoplication: A Case Report
This is a recognized but uncommon complication. The Nissen procedure involves wrapping the top of the stomach around the lower esophagus, which changes the normal anatomy and creates new fixation points. If the wrap loosens or adhesions develop in the wrong places, the stomach’s axis of rotation changes. The clinical lesson is that people who have had prior upper abdominal or diaphragmatic surgery and develop new-onset upper abdominal symptoms should have gastric volvulus at least considered in the workup, even if the symptoms seem like a straightforward return of reflux.
What Happens When the Twist Is Not Corrected Quickly
The urgency surrounding acute gastric volvulus comes from what happens to the stomach wall once it twists completely. The rotation kinks the blood vessels supplying the stomach, progressively starving the tissue of oxygen. If the twist is not relieved, the stomach wall begins to die, a process called necrosis. The stomach has an unusually rich blood supply compared to most other parts of the gastrointestinal tract, which normally protects it. But a complete volvulus can overcome even that redundancy, particularly when combined with massive gastric distension that raises pressure inside the organ.14Journal of Pediatric Surgery Case Reports. Acute gastric volvulus with total gastric necrosis and ischemia of the spleen and kidney
Once the stomach wall breaks down, the risk of perforation, sepsis, and death climbs steeply. Gastric volvulus is considered a life-threatening emergency that is notoriously hard to diagnose on initial presentation, which compounds the danger.16PubMed Central. Fatal gastric volvulus: forensic pathology considerations and postmortem CT findings In rare instances, the twist is severe enough to compromise blood flow not just to the stomach but to nearby organs. The spleen and the left kidney, both of which share vascular connections with the stomach, can suffer collateral ischemia when the twist is extreme.
Outcomes improve dramatically when the condition is recognized and treated promptly. But even with modern surgical care, the combination of acute gastric volvulus and a large paraesophageal hernia remains associated with significant morbidity and mortality.4PubMed Central.

How a Twisted Stomach Is Treated
Treatment depends on whether the volvulus is acute or chronic, whether the stomach tissue is still viable, and what underlying defect caused the twist in the first place. In an acute emergency with signs of obstruction or ischemia, surgery is the mainstay. The goals are to untwist the stomach, assess the tissue for necrosis, repair whatever structural problem allowed the twist (typically a hernia), and then fix the stomach in place so it cannot rotate again.
Laparoscopic surgery has become the preferred approach when the patient’s condition allows it. In one series, surgeons performed laparoscopic reduction of the volvulus, removed the hernia sac, closed the widened hiatal opening by stitching the diaphragmatic muscle edges together, and then performed a fundoplication to prevent reflux. To keep the stomach from twisting again, they anchored it to the front abdominal wall using a gastrostomy tube, a procedure called gastropexy.17PubMed Central. Laparoscopic repair of gastric volvulus In less complex cases, laparoscopic anterior gastropexy alone has been reported as effective for preventing recurrence.18PubMed Central. Chronic Gastric Volvulus with Laparoscopic Gastropexy after Endoscopic Reduction: A Case Report
For patients who are poor surgical candidates due to age or other medical conditions, endoscopic decompression can serve as a temporizing measure. An endoscope passed through the mouth can sometimes untwist the stomach and relieve the obstruction. In one reported case of a 92-year-old man with both a gastric volvulus and a sigmoid volvulus (a twist of the large intestine), doctors used upper endoscopic decompression initially and later performed a laparoscopic gastropexy. That case also illustrated a rare complication of treatment itself: after the gastropexy, the patient developed bleeding and ischemia of the stomach.19PubMed Central. Coexisting Organoaxial Gastric Volvulus and Sigmoid Volvulus With Complications While treatment complications are unusual, they reinforce that even the fix carries risk, particularly in elderly or frail patients.
Chronic Gastric Volvulus and the Question of When to Operate
Acute gastric volvulus demands urgent surgery. Chronic gastric volvulus presents a harder decision. Some patients have a partially twisted stomach that rotates back on its own, producing intermittent symptoms but never a complete obstruction. These people may live with episodic pain, nausea, and early satiety for a long time. The question of whether and when to operate on a chronic, recurrent twist remains debated.
Some clinicians argue that elective surgical repair is warranted once the diagnosis is established, because each episode of partial twisting carries a risk of progressing to a full, acute volvulus. Others take a more conservative view in patients who are elderly or have multiple comorbidities, reasoning that the risks of major surgery may outweigh the uncertain probability of a future acute event.8PubMed Central. Chronic Intrathoracic Gastric Volvulus Management: Could Less Be More? There is no large randomized trial comparing watchful waiting to elective repair, so the decision comes down to individual risk assessment between surgeon and patient.
A Brief Historical Note
The first documented case of gastric volvulus dates to 1866, described by an Italian pathologist named Berti during an autopsy. It took another three decades before a surgeon named Berg performed the first successful operation for the condition in 1897.20American Journal of Case Reports. Spontaneous Acute Mesenteroaxial Gastric Volvulus Diagnosed by Computed Tomography Scan in a Young Man For most of the time between then and now, the condition was diagnosed primarily through clinical suspicion and barium swallow X-rays, a combination that inevitably missed many cases. The advent of CT scanning in recent decades has substantially improved detection, and the shift toward laparoscopic techniques has made surgical repair less invasive. Still, the fundamental challenge has not changed much in over a century: the condition is rare enough that many physicians go an entire career without seeing one, which means the biggest barrier to treating it remains thinking of it in the first place.
