Esophagus disorders are problems with how your esophagus works. The esophagus is the tube that carries food from your mouth to your stomach. You usually don't notice it unless you swallow something too big, hot, or cold. You might also notice it if something is wrong. When that happens, you might feel pain or have trouble swallowing (dysphagia).

The cause depends on the type of disorder. Some run in families. Others are linked to allergic reactions to food or substances in your environment. Sometimes, the cause is unknown.

You may be more likely to develop an esophagus disorder if you:

• Are overweight or have obesity
• Are pregnant
• Take certain medicines
• Have had radiation treatmentt to your neck or chest
• Smoke or are around secondhand smoke

The most common esophagus problem is gastroesophageal reflux disease (GERD). This happens when the muscle at the bottom of your esophagus doesn't close properly. Stomach acid can move back up and irritate the esophagus.

Other esophagus disorders include:

• Heartburn is a burning feeling in your chest or throat. It is often caused by acid reflux.
• Barrett's Esophagus happens when the lining of your esophagus changes. It is often caused by chronic (long-term) GERD.
• Achalasia is a problem where the lower muscle in your esophagus doesn't relax like it should.
• Esophageal Spasms are muscle contractions that cause chest pain or swallowing problems.
• Eosinophilic Esophagitis (EoE) is a rare condition where certain white blood cells (eosinophils) build up in the esophagus, causing swelling, pain, and trouble swallowing.
• Esophageal Cancer is a type of cancer that starts in the tissues of the esophagus.

Symptoms can be different for each condition but may include:

• Pain in your chest, abdomen (belly), or back
• A cough or sore throat that doesn't go away
• Trouble swallowing or feeling like food is stuck
• A hoarse voice or wheezing
• Heartburn or a burning feeling in your stomach
• Tasting acid or food in the back of your mouth
• Food or liquid coming back up into your mouth (regurgitation)
• Losing weight without trying

Get medical help right away if you have chest pain with shortness of breath, or pain in your jaw or arm. These could be signs of a heart problem.

Your health care provider will ask about your symptoms and medical history. They may order one or more tests, such as:

• Upper gastrointestinal (GI) endoscopy. This test uses a tiny camera to look inside your esophagus and stomach.
• Biopsy. This test takes a small tissue sample to check.
• Barium swallow. This test uses imaging to see how you swallow.
• Esophageal manometry. This test checks how well your esophagus moves food to your stomach.
• Esophageal pH test. This test measures how often acid backs up into your esophagus and how long the acid stays there.

Treatment depends on what's causing the problem and your overall health. Some esophagus disorders get better with over-the-counter medicines, diet changes, or lifestyle changes. Others may need prescription medicine or surgery.

Without treatment, some disorders may lead to other problems, such as pneumonia, from food entering the windpipe. GERD, Barrett's esophagus, and achalasia can also raise your risk for esophageal cancer.

You can help prevent or reduce symptoms by:

• Not smoking and limiting alcohol
• Eating smaller meals
• Avoiding eating close to bedtime
• Wearing loose-fitting clothes
• Sleeping on your left side or raising the head of your bed
• Maintaining a healthy weight

Sometimes, after eating a large meal or lying down too soon after eating, you might feel acid coming up into your throat. This is called gastroesophageal reflux (GER). It happens when the muscle at the end of your esophagus (the tube that carries food from your mouth to your stomach) doesn't close properly. Stomach contents can then move back up and irritate the esophagus.

Having reflux occasionally is common. But if you have symptoms two or more times a week or if they cause damage to the lining of your esophagus, you may have gastroesophageal reflux disease (GERD). GERD is a chronic (long-lasting) condition that can cause discomfort and, over time, lead to other health problems.

Anyone can have GERD, including infants and children.

GERD can happen when the muscle at the bottom of your esophagus becomes weak or relaxes at the wrong time. You are more likely to have GERD if you:

• Are overweight or have obesity
• Are pregnant
• Smoke or are around secondhand smoke
• Have a hiatal hernia (when part of the stomach pushes up into the chest)

Certain foods, drinks, or medicines can also make GERD worse.

The most common symptom of GERD is heartburn. This is a burning feeling in your chest or throat. You can also have GERD without having heartburn. Other symptoms may include:

• Tasting acid or food in the back of your mouth
• A dry cough or hoarse voice
• Asthma-like symptoms
• Trouble swallowing

Get medical help right away if you have chest pain with shortness of breath, or pain in your jaw or arm. These can be signs of a heart problem.

Your health care provider will ask about your symptoms and medical history. They may recommend tests such as:

• Upper GI endoscopy to look at the esophagus and stomach lining with a tiny camera.
• Biopsy to check a small tissue sample.
• X-Ray to take pictures of the upper digestive system.
• Esophageal pH test to measure how often acid backs up the esophagus and how long the acid stays there.
• Esophageal manometry to check how well your esophagus moves food when you swallow.
• Transnasal esophagoscopy to look for damage to the esophagus by using a small tube with a camera.

Most people can manage GERD with lifestyle changes and medicine. In rare cases, surgery is needed.

Lifestyle changes can include:

• Eating smaller meals and avoiding lying down for at least 2-3 hours after eating
• Avoiding foods that trigger symptoms, such as spicy foods, chocolate, caffeine, or fatty foods
• Losing weight if needed
• Raising the head of your bed
• Quitting smoking

Medicines can include:

• Over-the-counter medicines, such as antacids
• Prescription medicines

If not treated, GERD can cause problems like inflammation of the esophagus, scarring, or changes in the tissue lining (Barrett's esophagus). It can also worsen asthma or cause chronic (long-term) cough or hoarseness.

You may be able to improve symptoms of GERD by:

• Avoiding alcohol and trigger foods
• Eating smaller meals
• Not eating close to bedtime
• Wearing loose-fitting clothes
• Sleeping on your left side or raising the head of your bed
• Maintaining a healthy weight

Bowel incontinence is the inability to control your bowels. When you feel the urge to have a bowel movement, you may not be able to hold it until you get to a toilet. Millions of Americans have this problem. It affects people of all ages - children and adults. It is more common in women and older adults. It is not a normal part of aging.

Causes include:

• Constipation
• Damage to muscles or nerves of the anus and rectum
• Diarrhea
• Pelvic floor disorders

Treatments include changes in diet, medicines, bowel training, or surgery.

A bowel movement is the last stop in the movement of food through your digestive tract. Your stool passes out of your body through the rectum and anus. Another name for stool is feces. It is made of what is left after your digestive system (stomach, small intestine, and colon) absorbs nutrients and fluids from what you eat and drink.

Sometimes a bowel movement isn't normal. Diarrhea happens when stool passes through the large intestine too quickly. Constipation occurs when stool passes through the large intestine too slowly. Bowel incontinence is a problem controlling your bowel movements. Other abnormalities with bowel movements may be a sign of a digestive problem.

If you have a swallowing disorder, you may have difficulty or pain when swallowing. Some people cannot swallow at all. Others may have trouble swallowing liquids, foods, or saliva. This makes it hard to eat. Often, it can be difficult to take in enough calories and fluids to nourish your body.

Anyone can have a swallowing disorder, but it is more common in older adults. It often happens because of other conditions, including:

• Nervous system disorders, such as Parkinson's disease and cerebral palsy
• Problems with your esophagus, including GERD (gastroesophageal reflux disease)
• Stroke
• Head or spinal cord injury
• Cancer of the head, neck, or esophagus

Medicines can help some people, while others may need surgery. Swallowing treatment with a speech-language pathologist can help. You may find it helpful to change your diet or hold your head or neck in a certain way when you eat. In very serious cases, people may need feeding tubes.
