Hiatus hernia

Hiatus hernia



Overview

A hiatal hernia happens when the upper part of the stomach bulges through the large muscle that separates the abdomen and the chest. The muscle is called the diaphragm.

The diaphragm has a small opening called a hiatus. The tube used for swallowing food, called the esophagus, passes through the hiatus before connecting to the stomach. In a hiatal hernia, the stomach pushes up through that opening and into the chest.

A small hiatal hernia usually doesn't cause problems. You may never know you have one unless your healthcare team discovers it when checking for another condition.

But a large hiatal hernia can allow food and acid to back up into your esophagus. This can cause heartburn. Self-care measures or medicines can usually relieve these symptoms. A very large hiatal hernia might need surgery.

Symptoms

Most small hiatal hernias cause no symptoms. But larger hiatal hernias can cause:

Heartburn.

Backward flow of swallowed food or liquids into the mouth, called regurgitation.

Backflow of stomach acid into the esophagus, called acid reflux.

Trouble swallowing.

Chest or abdominal pain.

Feeling full soon after you eat.

Shortness of breath.

Vomiting of blood or passing of black stools, which could mean bleeding in the digestive tract.

Causes

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 a hiatal hernia might be caused by:

Age-related changes in your diaphragm.

Injury to the area, for example, after trauma or certain types of surgery.

Being born with a very large hiatus.

Constant and intense pressure on the surrounding muscles. This can happen while coughing, vomiting, straining during a bowel movement, exercising or lifting heavy objects.

Risk factors

Hiatal hernias are most common in people who are:

Age 50 or older.

Obese.

Diagnosis

A hiatal hernia is often discovered during a test or procedure to determine the cause of heartburn or pain in the chest or upper abdomen. These tests or procedures include:

X-ray of your upper digestive system. X-rays are taken after you drink a chalky liquid that coats and fills the inside lining of your digestive tract. The coating allows your healthcare team to see an outline of your esophagus, stomach and upper intestine.

A procedure to look at the esophagus and stomach, called an endoscopy. Endoscopy is a procedure to examine your digestive system with a long, thin tube with a tiny camera, called an endoscope. The endoscope is passed down your throat and looks at the inside of your esophagus and stomach and checks for inflammation.

A test to measure muscle contractions of the esophagus, called an esophageal manometry. This test measures the rhythmic muscle contractions in your esophagus when you swallow. Esophageal manometry also measures the coordination and force used by the muscles of your esophagus.

Treatment

Most people with a hiatal hernia don't experience any symptoms and won't need treatment. If you experience symptoms, such as frequent heartburn and acid reflux, you may need medicine or surgery.

Medicines

If you experience heartburn and acid reflux, your healthcare professional may recommend:

Antacids that neutralize stomach acid. Antacids may provide quick relief. Overuse of some antacids can cause side effects, such as diarrhea or sometimes kidney problems.

Medicines to reduce acid production. These medicines are known as H-2-receptor blockers. They include cimetidine (Tagamet HB), famotidine (Pepcid AC) and nizatidine (Axid AR). Stronger versions are available by prescription.

Medicines that block acid production and heal the esophagus. These medicines are known as proton pump inhibitors. They are stronger acid blockers than H-2-receptor blockers and allow time for damaged esophageal tissue to heal. Proton pump inhibitors available without a prescription include lansoprazole (Prevacid 24HR) and omeprazole (Prilosec, Zegerid). Stronger versions are available in prescription form.

Surgery

Sometimes a hiatal hernia requires surgery. Surgery may help people who aren't helped by medicines to relieve heartburn and acid reflux. Surgery also may help people who have complications such as serious inflammation or narrowing of the esophagus.

Surgery to repair a hiatal hernia may involve pulling the stomach down into the abdomen and making the opening in the diaphragm smaller. Surgery also may involve reshaping the muscles of the lower esophagus. This helps keep the contents of the stomach from coming back up. Sometimes, hiatal hernia surgery is combined with weight-loss surgery, such as a sleeve gastrectomy.

Surgery may be performed using a single incision in the chest wall, called a thoracotomy. Surgery also may be performed using a technique called laparoscopy. In laparoscopic surgery, a surgeon inserts a tiny camera and special tools through several small incisions in the abdomen. The operation is then performed by a surgeon who views images from inside the body that are displayed on a video monitor.

Type of Doctor Department :A gastroenterologist, general surgeon, or thoracic surgeon

Charge Syndrome

Overview CHARGE syndrome is a recognizable genetic syndrome with known pattern of features. It is an extremely complex syndrome, involving extensive medical and physical difficulties that differ from child to child. CHARGE syndrome is correlated with genetic mutation to CHD7 and the prevalence of CHARGE syndrome is 1:10,000-1:15,000 live births. Babies with CHARGE syndrome are often born with life-threatening birth defects. They spend many months in the hospital and undergo many surgeries and other treatments. Swallowing and breathing problems make life difficult even when they come home. Most have hearing two little girls sitting on a carpet, one girl has a trach and is biting her finger.loss, vision loss, and balance problems that delay their development and communication. Despite these seemingly insurmountable obstacles, children with CHARGE syndrome often far surpass their medical, physical, educational, and social expectations. One of the hidden features of CHARGE syndrome is the ...

Dehydration Due to Diarrheal Diseases

Overview Dehydration occurs when you use or lose more fluid than you take in, and your body doesn't have enough water and other fluids to carry out its normal functions. If you don't replace lost fluids, you will get dehydrated. Anyone may become dehydrated, but the condition is especially dangerous for young children and older adults. The most common cause of dehydration in young children is severe diarrhea and vomiting. Older adults naturally have a lower volume of water in their bodies, and may have conditions or take medications that increase the risk of dehydration. This means that even minor illnesses, such as infections affecting the lungs or bladder, can result in dehydration in older adults. Dehydration also can occur in any age group if you don't drink enough water during hot weather — especially if you are exercising vigorously. You can usually reverse mild to moderate dehydration by drinking more fluids, but severe dehydration needs immediate medical treatment. ...

Ataxia with Vitamin E Deficiency

Synonyms of Ataxia with Vitamin E Deficiency AVED Familial Isolated Vitamin E Deficiency Isolated Vitamin E Deficiency General Discussion Ataxia with vitamin E deficiency (AVED) is a rare inherited neurodegenerative disorder characterized by impaired ability to coordinate voluntary movements (ataxia) and disease of the peripheral nervous system (peripheral neuropathy). AVED is a progressive disorder that can affect many different systems of the body (multisystem disorder). Specific symptoms vary from case to case. In addition to neurological symptoms, affected individuals may experience eye abnormalities, disorders affecting the heart muscles (cardiomyopathy), and abnormal curvature of the spine (scoliosis). AVED is extremely similar to a more common disorder known as Friedreich’s ataxia. AVED is inherited as an autosomal recessive trait. Vitamin E deficiency often occurs secondary to disorders that impair the absorption of vitamin E from fat including liver disorders, disorders of fat...
