GERD

FAQs on GERD

What is gastroesophageal reflux disease (GERD)?

GERD causes stomach contents (food or liquid) to leak backwards into the esophagus (the tube from the mouth to the stomach). The backwash can irritate the esophagus, causing heartburn and other symptoms.

What are the symptoms?

The common symptoms of GERD include chronic heartburn (burning pain in the chest) and regurgitation. Less common symptoms include chronic cough, sore throat, and a hoarse voice.

Who is at risk?

Those at risk for GERD include males and people with a family history of gastrointestinal symptoms. Obesity can increase the risk of GERD up to six-fold. Hiatal hernia, smoking, pregnancy, scleroderma, and excessive alcohol consumption are also risk factors.

How many people have GERD?

GERD affects 1 in 6 adult Canadians. 

How is GERD diagnosed?

GERD is often diagnosed based upon symptoms and response to anti-reflux medication. Yet, symptoms alone are not enough to diagnose GERD, and testing is required for conclusive diagnosis. Clinical studies reveal that as many as one in three patients taking proton pump inhibitors (PPIs) do not have GERD. If you have a diagnosis of GERD based upon symptoms, take PPIs regularly, and still have reflux symptoms, speak to a GI about a reflux test.

Are there certain medical conditions associated with GERD?

Being overweight is a definite aggravating factor for reflux by increasing intrabdominal pressure.

Patients with long standing diabetes may develop decreased gastric emptying due to nerve injury to the stomach. This can also occur after certain stomach surgeries. Ulcers or cancers that block the stomach from emptying can cause reflux. Certain medications can contribute to reflux. Scleroderma is a rheumatological problem that can lead to reflux secondary to poor esophageal emptying and a decreased lower esophageal sphincter pressure.

Can reflux cause cancer?

15% of patients who have GERD may develop a Barrett’s esophagus which results in a change in the normal esophageal mucosa to a type of lining that is more of an intestinal type. A gastroscopy with esophageal biopsies is the only definitive way to make this diagnosis of a Barrett’s esophagus.. There are no specific symptoms for Barrett’s esophagus and the risk of a cancer developing in the setting of a Barrett’s esophagus is very low.

Do the medications for GERD cure acid reflux?

The medications are very effective to treat reflux. However they do not cure the disease. The medications work to decrease the acid production by the stomach and once you stop the drugs the stomach returns to its normal ability to make acid. The symptoms of heartburn will therefore often recur after the medication is stopped. If altering lifestyle measures do not prevent the symptoms from recurring then individuals may require medication on a long term basis. This may include using it as necessary when symptoms recur. Some individuals need medication on a daily maintenance basis.

Does having GERD for a long time put me at risk of other illnesses?

Some people may experience problems from acid reflux in areas other than the esophagus. These are called extraesophageal symptoms. Sometimes the acid can spill over into the throat region and vocal cords and cause problems with a voice change, hoarseness, sore throat, and lump-like feeling in the throat region.

If the acid spills into the lungs, it can cause problems with cough, asthma, or infections. These symptoms can be the primary problem of reflux and the person may not even complain of associated burning in the chest or throat region. Some people develop a condition known as Barrett’s esophagus, which is severe damage to the cells lining the bottom of the esophagus. Doctors believe Barrett’s esophagus may increase the chance of developing esophageal cancer.

I am pregnant and am suffering from GERD. Is something wrong?

It is very common during pregnancy for reflux to be a problem. The fetus increases the abdominal pressure and the hormones of pregnancy may decrease the lower esophageal sphincter pressure. Also If the stomach doesn’t empty because of a motility problem or a blockage then there is a greater risk for acid to reflux into the esophagus.

I have GERD. Are there complications that I should be aware of before considering surgery?

Complications can occur from surgery with 5-10% of patients. These include making the wrap too tight and developing problems swallowing one’s food, accidental injury to the spleen requiring removal of the spleen, post-operative hernia formation developing diarrhea, inability to burp and loosening of the wrap over time with recurrent reflux needing medication.

I have GERD. When should I consider having surgery?

There are some special circumstances where surgery may be of value for those having troublesome retrosternal burning and extraesophageal symptoms of cough, asthma, voice change and pulmonary infections despite of a trial with at least a double dose of a proton pump inhibitor. It is important to confirm that there is increased acid present in the esophagus with a pH test. Some people who regurgitate fluid that is very troublesome may benefit from surgery. There are some people who respond to the drugs but have side effects from the drugs, find them too expensive or simply don’t like taking medications. This group would benefit from surgery.

People who continue to have symptoms even with a twice a day dose of a proton pump inhibitor and the 24 hour ph test is normal should look to be tested for other problems as this is not in keeping with acid reflux.

I have heard about bacteria that can cause problems. Do these contribute to reflux?

The bacterium is called Helicobacter pylori (H. pylori). This is a common bacterium that infects the stomach and may cause about 10% of people with the bacterium to develop an ulcer. As a rule, one does not look for H. pylori in the setting of reflux.

Is there anything that can be done through the scope to treat reflux?

There have been some endoscopic techniques that have been developed that can increase the lower esophageal sphincter pressure but presently they are more experimental and do not have a role in the treatment of reflux.

What does it mean if I don’t get better with GERD medications?

The medications we use to treat acid reflux are very effective. There is a very small percentage of people who continue to experience acid reflux even with the medications. However there is a group of patients who have symptoms suggestive of reflux and yet there is no increased acid present. These patients may be refluxing bile that is produced by the liver and pancreatic secretions from the pancreas.  Medical treatment of this group may also be challenging and a foam barrier and prokinetic drugs may be helpful.

Sometimes more than one drug may be necessary to threat this problem. Some people may also experience hypersensitivity of the esophagus to normal amounts of acid or contractions of the esophageal wall. This is called visceral hypersensitivitiy. Stress may be a contributing factor to esophageal visceral hypersensitivity. A certain class of antidepressants called tricyclic antidepressants which alter the way the brain perceives painful stimuli may be of value in these situations.

Are treatment options available?

GERD can be treated with lifestyle changes, such as weight loss, healthier, smaller meals, and not eating Just before bed time. Prescription and over-the-counter medicines, like proton pump inhibitors, can lower the amount of acid released in your stomach. 􀀩or patients who do not respond to lifestyle changes and medication, anti-reflux procedures may also be an option.

What happens if GERD goes untreated?

In addition to its negative impact on health-related quality of life, GERD may lead to serious diseases including Barrett’s esophagus. Over a quarter of GERD patients may progress to Barrett’s esophagus in their lifetime. If untreated, Barrett’s esophagus may progress to esophageal cancer. Esophageal cancer may not be curable depending on the stage at diagnosis. It has a low five-year survival rate of 14%.

What is a hiatus hernia? Could this be causing my heartburn?

Normally the esophagus is located above the diaphragm and the stomach is below the diaphragm. The lower esophageal sphincter lies at the level of the diaphragm in between the esophagus and stomach. The diaphragm is a muscle that separates the chest from the abdomen. A hiatus hernia occurs when a portion of the stomach adjacent to the esophagus pushes up thru the diaphragm and rests above the diaphragm in the chest region.

A hiatus hernia is a common occurrence and often causes no problems. Many individuals have reflux and do not have a hiatus hernia. In some individuals it may contribute to reflux. The diaphragm squeezes on the sphincter when it is normally located at the level of the diaphragm and helps to increase the pressure in this region.

When the sphincter is situated above the diaphragm in the setting of a hiatus hernia the diaphragm can no longer assist the effect of the lower esophageal sphincter pressure. Also sometimes acid can be trapped in the hiatus hernia and be a reservoir for acid to more readily reflux into the esophagus.
