A hiatal hernia occurs when part of the stomach pushes up through the diaphragm and into the chest cavity through an opening called the esophageal hiatus. While many people with hiatal hernias experience no symptoms, others suffer from heartburn, acid reflux, difficulty swallowing, and chest pain. In severe cases, surgery may be necessary. Weight loss after hiatal hernia surgery is a common concern, and this article will explore the reasons behind it, management strategies, and when to seek medical advice.
Understanding Hiatal Hernias
A hernia is a general term for a bulge of tissue through a tear or weakness in a muscular wall. A hiatal hernia specifically involves the stomach pushing through the diaphragm, the muscle wall separating the abdomen and chest.
Symptoms of Hiatal Hernias
Many people with hiatal hernias do not experience any symptoms. However, when symptoms do occur, they are often related to acid reflux (GERD) and may include:
- Heartburn: A burning sensation in the chest, especially after eating.
- Noncardiac Chest Pain: Recurring chest pain that feels like angina but isn't heart-related.
- Indigestion: Feeling full soon after eating, with a burning type of abdominal pain.
- Burping and Regurgitation: Food, gas, and acid rising back into your throat.
- Difficulty Swallowing: A sensation of a lump in your throat when you swallow.
- Sore Throat and Hoarseness: Due to acid irritation.
Other possible symptoms may include nausea, shortness of breath, and upper abdominal or lower chest pain, especially with larger hernias.
Causes and Risk Factors
Hiatal hernias occur when there is a weakness in the tissues surrounding the esophageal hiatus, the opening in the diaphragm where the esophagus passes through. Factors that can contribute to this weakness include:

- Chronic Coughing or Sneezing
- Chronic Straining to Poop (Constipation)
- Chronic Obesity (BMI greater than 30)
- Frequent Vomiting
- Intense Exercise or Heavy Lifting
- Pregnancy and Childbirth
Obesity and age over 50 are also risk factors. Some individuals may have a genetic predisposition due to a larger-than-normal hiatus.
Complications of Hiatal Hernias
The most common complication of hiatal hernias is chronic acid reflux, which can lead to:
- Esophagitis: Inflammation of the esophagus lining.
- Esophageal Stricture: Narrowing of the esophagus due to scarring.
- Barrett's Esophagus: Tissue changes that are considered precancerous.
In rare cases, the hernia can become stuck or compressed, leading to gastrointestinal obstruction, gastritis, or ischemia (reduced blood supply).
Hiatal Hernia Surgery
Surgery is typically considered when symptoms are severe and do not improve with medication and lifestyle changes, or when there is a narrowing of the esophagus. The goal of surgery is to reduce pain and discomfort.
Surgical Procedures
Hiatal hernias can be repaired through traditional open surgery or robotic-assisted laparoscopic surgery. Laparoscopic surgery generally offers fewer risks and faster recovery times. During the procedure, the surgeon pushes the stomach back below the diaphragm and may take steps to prevent recurrence, such as reconstructing or repairing the esophagus.

Weight Loss After Hiatal Hernia Surgery
Weight loss is a common experience after hiatal hernia surgery. This can be attributed to several factors related to the surgery and the recovery process.
Reasons for Weight Loss
- Reduced Appetite: Anesthesia, medications, and discomfort can decrease appetite.
- Dietary Changes: Post-operative diets typically start with clear liquids and progress to soft foods, reducing calorie intake.
- Metabolic Changes: The body's metabolism increases temporarily to heal tissues.
- Digestive Issues: Surgery can temporarily disrupt normal digestive functions, leading to nausea, vomiting, or changes in bowel habits.
- Reduced Physical Activity: Limited activity during recovery can lead to muscle loss if protein intake is inadequate.
- Smaller Stomach Size: The procedure may reduce the size of the stomach, leading to feeling full with less food.
Expected Weight Loss
Most people who undergo hiatal hernia surgery can expect to lose between 5 and 10 pounds. According to studies, patients may lose an average of 5-10% of their body weight in the months following hiatal hernia repair.
The Post-Operative Diet
The goal of a modified post-operative diet is to minimize bloating, nausea, vomiting, dysphagia, and retching. Minimizing these side effects improves patient satisfaction and reduces the likelihood of additional healthcare visits.
- Clear Liquid Diet: Immediately after surgery, patients start with a clear liquid diet once they are fully awake and free of nausea.
- Post-Esophageal Surgery Diet: If clear liquids are tolerated well, patients advance to a "post-esophageal surgery" diet, which is a soft or puree diet designed to minimize dysphagia and avoid retching. Carbonated beverages are avoided to minimize bloating.
- Eating Behaviors: Patients are advised to eat small volume meals, chew food well, eat slowly, and sit upright while eating and for 30-60 minutes following a meal.
- Diet Advancement: Patients typically remain on the puree diet for 2 weeks and then gradually advance their diet if they are doing well. Those still experiencing dysphagia may need to remain on the puree diet for up to 6 weeks.
Dietary Guidelines
- Protein and Caloric Intake: Methods for boosting protein and caloric intake are provided to patients.
- Pill Management: Large pills should be crushed for the first 2 weeks after surgery to avoid retching from pill dysphagia and pill esophagitis.
- Foods to Avoid: Spicy, processed, and fatty foods, as well as carbonated and caffeinated drinks, should be avoided.
Activity Restrictions
Activity restrictions are designed to avoid sudden spikes in intra-abdominal pressure that can result from excessive lifting, strenuous exercise, or blunt force trauma.
- Lifting Restrictions: Patients are advised to avoid heavy lifting, awkward lifting, or excessive straining, including lifting more than 15 pounds for 6 weeks.
- Encouraged Activity: Early and frequent ambulation and non-strenuous activity are encouraged.
Long-Term Follow-Up
- Annual Clinic Visit: Patients should have an annual clinic visit for assessment of gastroesophageal symptoms.
- Routine Imaging: Routine follow-up imaging is not generally recommended for asymptomatic patients.
- Imaging for Symptomatic Patients: Imaging is recommended when symptoms such as heartburn, dysphagia, regurgitation, nausea, vomiting, or retching emerge.
- Barrett's Esophagus: Patients with Barrett's esophagus should continue to have routine surveillance endoscopy. Antireflux surgery should only be offered to treat symptoms of gastroesophageal reflux disease, not as an antineoplastic treatment.
Managing Weight Loss After Hernia Surgery
While some weight loss is normal, it's important to manage it to ensure a healthy recovery.

Nutrition Tips
- Balanced Diet: Focus on nutrient-dense foods high in protein to aid healing and maintain muscle mass.
- Small, Frequent Meals: Eating smaller portions more frequently can help increase calorie intake without overwhelming the digestive system.
- Hydration: Adequate fluid intake is essential, but avoid filling up on liquids before meals.
- Supplements: Nutritional supplements can help meet calorie and protein needs if recommended by a doctor.
Monitoring Recovery
- Consult Healthcare Providers: Regular follow-ups can help monitor weight changes and address any concerns promptly.
- Physical Activity: Gradually reintroducing light exercises, as advised by a doctor, can help rebuild muscle mass and stimulate appetite.
When to Seek Medical Advice
While some weight loss is normal after hernia surgery, significant or rapid weight loss warrants medical attention. Signs to watch for include:
- Persistent Nausea or Vomiting
- Inability to Eat or Drink Adequately
- Signs of Infection: Fever, redness, or swelling at the surgical site
- Severe Pain: That doesn’t improve with medication
The Connection Between Hiatal Hernias and Weight Loss
Doctors often recommend weight loss for overweight hiatal hernia patients, both before and after surgery.
Pre-Surgery
Weight loss can significantly improve and even resolve hiatal hernias, reducing painful symptoms. Gradual, healthy changes are recommended for slow and steady weight loss.
Post-Surgery
The body's response to surgery, loss of appetite, and dietary restrictions can all lead to weight loss. If the stomach lost any of its capacity during the procedure, you may lose weight and keep it off. Rapid weight loss after surgery is not normal, and you should consult your doctor if you lose more than two pounds per week.
Addressing Common Concerns
Will My Stomach Shrink After Hernia Repair?
Repairing a hernia can reduce bulging, making the abdomen appear flatter. While the stomach organ doesn’t actually shrink, the absence of the hernia bulge can make the abdominal area look smaller.
Can a Hernia Cause Weight Loss?
A hernia itself may not directly cause weight loss, but the associated symptoms and treatments can contribute to it.
