Alternative Names:Hernia – hiatal, Hiatus hernia.
.Hiatal hernia is a condition in which a portion of the stomach protrudes upward into the chest, through an opening in the diaphragm. The diaphragm is the sheet of muscle that separates the chest from the abdomen. It is used in breathing.
The diaphragm normally has a small opening (hiatus) that allows your food tube (esophagus) to pass through on its way to connect to your stomach. The stomach can push up through this opening and cause a hiatal hernia.

The esophagus runs through the diaphragm to the stomach. It functions to carry food from the mouth to the stomach.The esophagus passes through the diaphragm just before it meets the stomach, through an opening called the esophageal hiatus.
A hiatal hernia occurs when part of the stomach protrudes up into the chest through the sheet of muscle called the diaphragm. This may result from a weakening of the surrounding tissues and may be aggravated by obesity and/or smoking.
In most cases, a small hiatal hernia doesn’t cause problems, and you may never know you have a hiatal hernia unless your doctor discovers it when checking for another condition. But a large hiatal hernia can allow food and acid to back up into your esophagus, leading to heartburn and chest pain. Self-care measures or medications can usually relieve these symptoms, although a very large hiatal hernia sometimes requires surgery.
There are two major kinds of hiatus hernia:
The most common (95%) is the sliding hiatus hernia, where the gastroesophageal junction moves above the diaphragm together with some of the stomach.
The second kind is rolling (or paraesophageal) hiatus hernia, when a part of the stomach herniates through the esophageal hiatus and lies beside the esophagus, without movement of the gastroesophageal junction. It accounts for the remaining 5% of hiatus hernias.
A third kind is also sometimes described, and is a combination of the first and second kinds.
Small hiatal hernias
Most small hiatal hernias cause no signs or symptoms.
Large hiatal hernias
Larger hiatal hernias can cause signs and symptoms such as:
*Heartburn, worse when bending over or lying down
A hiatal hernia by itself rarely causes symptoms — pain and discomfort are usually due to the reflux of gastric acid, air, or bile. Reflux happens more easily when there is a hiatal hernia, although a hiatal hernia is not the only cause of reflux.
A hiatal hernia occurs when weakened muscle tissue allows your stomach to bulge up through your diaphragm. It’s not always clear why this happens, but pressure on your stomach may contribute to the formation of hiatal hernia.
How a hiatal hernia forms
Your diaphragm is a large dome-shaped muscle that separates your chest cavity from your abdomen. Normally, your esophagus passes into your stomach through an opening in the diaphragm called the hiatus. Hiatal hernias occur when the muscle tissue surrounding this opening becomes weak, and the upper part of your stomach bulges up through the diaphragm into your chest cavity.
Possible causes of hiatal hernia are:
*Injury to the area
*An inherited weakness in the surrounding muscles
*Being born with an unusually large hiatus
*Persistent and intense pressure on the surrounding muscles, such as when coughing, vomiting, or straining during a bowel movement or while lifting heavy objects.
The following are risk factors that can result in a hiatus hernia.
*Increased pressure within the abdomen caused by:
*Heavy lifting or bending over
*Frequent or hard coughing
*Pregnancy and delivery
*Straining with constipation
*Obesity (extra weight pushes down on the abdomen increasing the pressure)
*Use of the sitting position for defecation
*Drug use, such as cocaine.
In most cases, sufferers experience no discomfort and no treatment is required. However, when the hiatal hernia is large, or is of the paraesophageal type, it is likely to cause esophageal stricture and discomfort. Symptomatic patients should elevate the head of their beds and avoid lying down directly after meals until treatment is rendered. If the condition has been brought on by stress, stress reduction techniques may be prescribed, or if overweight, weight loss may be indicated. Medications that reduce the lower esophageal sphincter (or LES) pressure should be avoided. Antisecretory drugs like proton pump inhibitors and H2 receptor blockers can be used to reduce acid secretion.
Where hernia symptoms are severe and chronic acid reflux is involved, surgery is sometimes recommended, as chronic reflux can severely injure the esophagus and even lead to esophageal cancer.
The surgical procedure used is called Nissen fundoplication. In fundoplication, the gastric fundus (upper part) of the stomach is wrapped, or plicated, around the inferior part of the esophagus, preventing herniation of the stomach through the hiatus in the diaphragm and the reflux of gastric acid. The procedure is now commonly performed laparoscopically. With proper patient selection, laparoscopic fundoplication has low complication rates and a quick recovery.
Complications include gas bloat syndrome, dysphagia (trouble swallowing), dumping syndrome, excessive scarring, and rarely, achalasia. The procedure sometimes fails over time, requiring a second surgery to make repairs.
Lifestyle & Home Remedy:
Lifestyle changes may help control the signs and symptoms of acid reflux caused by a hiatal hernia. Consider trying to:
*Eat several smaller meals throughout the day rather than a few large meals.
*Avoid foods that trigger heartburn, such as chocolate, onions, spicy foods, citrus fruits and tomato-based foods.
*Limit the amount of fatty foods you eat.
*Sit up after you eat, rather than taking a nap or lying down.
*Eat at least three hours before bedtime.
*Lose weight if you’re overweight or obese.
*Elevate the head of your bed 6 inches (about 15 centimeters).
*Work to reduce the stress in your daily life.
Some alternative medicine practitioners claim to have discovered a way to cure a hiatal hernia by pushing the stomach back to its normal position below the diaphragm. Practitioners may use their hands to apply pressure to the abdomen and manipulate the stomach.
There’s no evidence that such manipulation works to cure hiatal hernia. No clinical trials of the technique have been conducted.
But Practicing Regular Yoga Exercise & meditation has definitely got some better effect.
A hiatus hernia normally does not cause any symptoms. The condition promotes reflux of gastric contents (via its direct and indirect actions on the anti-reflux mechanism) and thus is associated with gastroesophageal reflux disease (GERD). In this way a hiatus hernia is associated with all the potential consequences of GERD – heartburn, esophagitis, Barrett’s esophagus, esophageal cancer and dental erosion. However the risk attributable to the hiatus hernia is difficult to quantify, and at most is low.
Besides discomfort from GERD and dysphagia, hiatal hernias can have severe consequences if not treated. While sliding hernias are primarily associated with gastroesophageal acid reflux, rolling hernias can strangulate a portion of the stomach above the diaphragm. This strangulation can result in esophageal or GI tract obstruction and the tissue can even become ischemic and necrose.
Another severe complication, although very rare, is a large herniation that can restrict the inflation of a lung, causing pain and breathing problems.
Most cases are asymptomatic.
Controlling risk factors such as obesity may help prevent hiatal hernia.
