Gastroesophageal Reflux Disease (Gerd)

Your stomach acid sometimes flows back up into your food pipe (esophagus). This is called acid reflux. It happens when a muscle at the bottom of your esophagus, which usually keeps stomach acid down, relaxes when it shouldn't. This backflow can cause a burning sensation in your chest, called heartburn, and other uncomfortable feelings.

Acid reflux is a common problem that many people experience occasionally. However, if it happens often or constantly, it can lead to a condition called Gastroesophageal Reflux Disease, or GERD. GERD happens when stomach acid regularly flows back up into your esophagus, irritating the lining.

Most people can handle the discomfort of GERD by making changes to their lifestyle, like eating smaller meals and avoiding foods that trigger it. Medicine can also help. In rare cases, surgery might be necessary to ease symptoms.

Gastroesophageal Reflux Disease (GERD) is a common condition where stomach acid flows back up into the food pipe. This can cause various symptoms.

Common signs of GERD include:

• Heartburn: A burning feeling in your chest, often after eating. It's frequently worse when you're lying down or at night.
• Acid reflux: You might feel food or a sour liquid coming up into your throat.
• Upper belly or chest pain: This pain can be a symptom of GERD, and sometimes is mistaken for other problems.
• Difficulty swallowing (dysphagia): This means you have trouble getting food down.
• Feeling a lump in your throat: A sensation of something being stuck in your throat.

If acid reflux happens more often at night, you might also notice:

• Chronic cough: A persistent cough can be a sign of nighttime reflux.
• Sore throat or hoarseness (laryngitis): This happens when the vocal cords become inflamed, often due to acid irritation.
• Asthma problems getting worse: Acid reflux can worsen existing asthma or lead to new asthma problems.

It's important to remember that these are just some of the possible symptoms. If you're experiencing these or other unusual digestive issues, it's best to talk to a doctor for proper diagnosis and treatment. The doctor can determine if your symptoms are due to GERD or another condition.

If you have chest pain, especially if it's accompanied by trouble breathing or pain in your jaw or arm, get medical help right away. These could be signs of a heart attack, and prompt attention is vital.

It's also a good idea to see a doctor if:

• You're having very bad or frequent heartburn (GERD).
• You're using over-the-counter heartburn medicine more than twice a week.

Heartburn that's severe or happens often could be a sign of a more serious problem. A doctor can help figure out what's going on and recommend the best treatment plan. Taking heartburn medicine too often can also cause other health issues, so it's important to talk to a healthcare professional about your situation.

Acid reflux, also known as GERD, happens when stomach contents come back up into the esophagus too often. This can be stomach acid or, less commonly, other substances from the stomach.

Imagine your esophagus as a tube connecting your mouth to your stomach. At the bottom of the esophagus is a special ring of muscle called the lower esophageal sphincter (LES). When you swallow, this muscle relaxes to let food and liquids pass into your stomach. Then, it closes again.

If the LES doesn't relax and close properly, or if it gets weak, stomach contents can flow back up into the esophagus. This constant flow of acid or other stomach material irritates the lining of the esophagus, much like how rubbing sandpaper against skin would cause it to become sore and inflamed. This irritation is what causes the symptoms of GERD.

A hiatal hernia happens when part of your stomach pushes up through your diaphragm, a muscle separating your chest from your abdomen. This can cause a problem called acid reflux.

Several things can make acid reflux (GERD) more likely:

• Being overweight or obese: Extra weight puts pressure on your stomach, making it easier for stomach acid to flow back up.
• Hiatal hernia: As mentioned, this is when part of your stomach moves into your chest, which often worsens acid reflux symptoms.
• Pregnancy: A growing baby puts pressure on the stomach and can also weaken the valve between the stomach and esophagus, allowing acid to reflux.
• Connective tissue disorders (like scleroderma): These conditions can affect the muscles and tissues around the esophagus and stomach, making it harder for them to function properly and increasing the risk of acid reflux.
• Slow stomach emptying: If your stomach takes longer to empty, food stays in there longer, giving stomach acid more time to flow back up.

Things that can make acid reflux symptoms worse include:

• Smoking: Smoking can weaken the muscles that help prevent acid reflux.
• Large or late meals: Eating a lot of food at once or eating close to bedtime gives your stomach more acid to work with and can also relax the valve between your stomach and esophagus.
• Certain foods: Fatty, fried, or spicy foods can trigger reflux in some people because they can relax the valve and increase stomach acid production.
• Certain drinks: Alcohol and coffee can also relax the valve and increase acid production, leading to more reflux.
• Certain medicines: Some medications, like aspirin, can irritate the lining of the esophagus and make reflux symptoms worse.

Chronic inflammation in the esophagus (the tube that carries food from your mouth to your stomach) can lead to several problems over time.

• Esophagitis: This is when the lining of the esophagus becomes inflamed. Stomach acid can irritate and damage the esophagus's tissue, causing inflammation, bleeding, and sometimes a sore called an ulcer. This inflammation can make swallowing painful and difficult. Think of it like a burn on the inside of your food pipe.

• Esophageal Stricture: Repeated exposure to stomach acid can cause scar tissue to form in the esophagus. This scar tissue gradually narrows the food passage, making it harder to swallow. It's like a pipe getting gradually squeezed, making it harder for food to move through.

• Barrett's Esophagus: Damage from stomach acid can change the cells that line the lower part of your esophagus. This change is called Barrett's esophagus, and it increases your risk of getting esophageal cancer. These changes are a sign that the esophagus is being hurt by acid over a long period. It's important to note that having Barrett's esophagus doesn't automatically mean you'll get cancer, but it does make you more likely to.

These problems are often related to conditions like acid reflux, where stomach acid backs up into the esophagus. If you have persistent heartburn, difficulty swallowing, or other symptoms, it's crucial to talk to your doctor. Early diagnosis and treatment can help prevent these complications from getting worse.

Doctors use various tests to diagnose and monitor gastroesophageal reflux disease (GERD). GERD happens when stomach acid flows back into the esophagus, causing discomfort.

How is GERD Diagnosed?

A doctor might suspect GERD based on your symptoms and a physical exam. To confirm the diagnosis or check for problems, they might recommend these tests:

• Acid (pH) Monitor: A small device, like a thin tube (catheter) inserted through your nose or a capsule swallowed during an endoscopy, is placed in your esophagus. This device measures how often and for how long stomach acid flows back up into your esophagus. The device is connected to a small computer you wear. The capsule passes out of your body in your stool after a few days.

• Upper Digestive System X-ray: This test uses X-rays after you drink a special, chalky liquid that coats your esophagus and stomach. This makes the organs show up clearly on the X-ray, allowing the doctor to see if there are any problems like narrowing or blockages. Sometimes, a barium pill is swallowed instead of the liquid. This can help identify narrowing in the esophagus that might be causing trouble swallowing.

• Esophageal Manometry: This test measures how well the muscles in your esophagus contract and relax when you swallow. It's often used if you have trouble swallowing. The test measures the strength and coordination of the esophageal muscles.

• Esophagoscopy (Endoscopy): A thin, flexible tube with a tiny camera at the end is inserted through your mouth and down your throat into your esophagus. This allows the doctor to see the esophagus, stomach, and the beginning of your small intestine (duodenum) directly. While an endoscopy can't always detect reflux, it can find inflammation in the esophagus or other problems. The doctor may also take a small tissue sample (biopsy) during the procedure to check for complications like Barrett's esophagus (changes in the lining of the esophagus). If a narrowing is found, the doctor can sometimes stretch or widen it during the procedure to improve swallowing.

These tests help doctors understand the cause of your symptoms and determine the best treatment plan. Each test has its own advantages and limitations, and a doctor will recommend the most appropriate one based on your individual situation.

Managing Gastroesophageal Reflux Disease (GERD)

Gastroesophageal reflux disease (GERD) happens when stomach acid flows back up into the esophagus, causing discomfort and sometimes damage. Fortunately, there are several ways to manage GERD, often starting with simple lifestyle changes and over-the-counter medications.

Lifestyle Changes and Over-the-Counter Medications

Most doctors recommend trying lifestyle changes and non-prescription medications first. These include things like eating smaller meals, avoiding foods that trigger your symptoms (like spicy or fatty foods), and losing weight if you're overweight. Raising your head slightly while sleeping can also help. If these simple steps don't work after a few weeks, prescription medications or further testing might be needed.

Over-the-Counter Medications for GERD

Several over-the-counter options can help neutralize stomach acid or reduce its production:

• Antacids: These medications, like Mylanta, Rolaids, and Tums, work by neutralizing stomach acid. While they can provide quick relief, they won't heal any damage to the esophagus caused by acid reflux. Taking too many antacids can cause side effects like diarrhea or, rarely, kidney problems.

• Histamine (H-2) Blockers: These medicines, such as cimetidine (Tagamet HB), famotidine (Pepcid AC), and nizatidine (Axid), reduce the amount of acid your stomach produces. They don't work as quickly as antacids but provide longer relief, sometimes up to 12 hours. Stronger versions are available with a prescription.

• Proton Pump Inhibitors (PPIs): These are stronger acid blockers than H-2 blockers and allow time for the damaged esophageal lining to heal. Over-the-counter PPIs include lansoprazole (Prevacid), omeprazole (Prilosec OTC), and esomeprazole (Nexium). Always talk to your doctor before starting any new medication.

Prescription Medications for GERD

Prescription-strength medications for GERD can be more potent and come in stronger forms of H-2 blockers and PPIs.

• Prescription-strength PPIs: These include esomeprazole (Nexium), lansoprazole (Prevacid), omeprazole (Prilosec), pantoprazole (Protonix), rabeprazole (Aciphex), and dexlansoprazole (Dexilant). While generally safe, possible side effects include diarrhea, headaches, nausea, or, in rare cases, low levels of vitamin B-12 or magnesium.

• Prescription-strength H-2 blockers: These are stronger versions of the over-the-counter H-2 blockers.

Surgical Options for GERD

If medications don't control GERD or you prefer to avoid long-term medication use, surgery might be an option.

• Fundoplication: This surgery involves wrapping the top part of the stomach around the lower part of the esophagus to strengthen the valve that prevents acid reflux. This can be done using a minimally invasive technique called laparoscopic surgery. The wrapping can be partial (like Toupet fundoplication) or complete (like Nissen fundoplication). Your doctor will recommend the best type for you.

• LINX Device: This is a small, flexible ring of magnetic beads placed around the connection between the esophagus and stomach. The magnets keep the valve closed to prevent acid reflux, but allow food to pass through easily. It is a minimally invasive procedure.

• Transoral Incisionless Fundoplication (TIF): This newer procedure uses an endoscope (a thin tube with a camera) to tighten the lower esophageal sphincter with small fasteners. It's a less invasive surgery than other fundoplications, with quicker recovery times. TIF may not be an option if you have a large hiatal hernia, but it can sometimes be combined with other procedures.

Important Considerations

Obesity can increase the risk of GERD. If you are overweight, your doctor might suggest weight-loss surgery as a treatment option. Always discuss all treatment options and potential side effects with your healthcare provider before making a decision. They can help you determine the best approach for your specific needs.

Making lifestyle changes can often help reduce how often you get acid reflux. Here are some tips:

• Quit smoking. Smoking weakens the muscle that keeps stomach acid from coming up into your esophagus, making reflux more likely.

• Raise your bed. If heartburn bothers you at night, elevate the head of your bed. Use blocks of wood or cement, placing them under the bed frame at the head. You need to raise the head about 6 to 9 inches. If you can't raise your bed, you can use a wedge between your mattress and box spring to achieve the same elevation for your upper body. Putting extra pillows under your head isn't as effective.

• Sleep on your left side. Try to sleep on your left side. This can help prevent stomach acid from flowing back up into your esophagus.

• Wait before lying down. Give your stomach at least three hours to digest food before lying down or going to bed.

• Eat mindfully. Chew your food thoroughly and take your time eating. Put your fork down after each bite and pick it up again only when you've chewed and swallowed that bite.

• Avoid trigger foods and drinks. Some foods and drinks can make acid reflux worse. These include alcohol, chocolate, caffeine, fatty foods, and peppermint. Knowing your personal triggers can be helpful.

Some herbal remedies, like ginger, chamomile, and slippery elm, are sometimes suggested for GERD (Gastroesophageal Reflux Disease). However, there's no strong scientific evidence that these remedies treat GERD or repair damage to the esophagus. If you're considering using alternative therapies, talk to your doctor first. They can give you personalized advice.
