Understanding Acid Reflux: Causes and Solutions

About 20% of people in the U.S. suffer from acid reflux, also known as gastroesophageal reflux disease (GERD). This condition can really affect how you live your life¹. This article will look into the reasons, signs, problems, diagnosis, and ways to treat this ongoing issue.

Acid reflux happens when stomach contents, including acid, go back up into the esophagus. This can cause pain and harm the esophagus lining². Being overweight, pregnant, or having certain habits can make GERD worse¹. It’s important to know the causes and find ways to deal with it.

Key Takeaways

• Acid reflux, or GERD, affects about 20% of people in the U.S¹..
• Smoking, eating big meals, and some medicines can make acid reflux worse¹.
• Being overweight, pregnant, or having certain health issues can also lead to GERD¹.
• Food like high-fat and spicy dishes, and drinks like coffee and soda can trigger acid reflux¹.
• Managing acid reflux might mean changing your lifestyle, taking medicine, or even surgery in some cases³.

What is Acid Reflux?

Acid reflux, also known as gastroesophageal reflux disease (GERD), happens when stomach acid flows back into the esophagus. This can cause discomfort and even damage⁴. The acid can irritate the esophagus, leading to heartburn, regurgitation, and trouble swallowing⁴.

It happens when the lower esophageal sphincter (LES) relaxes too much. This muscle acts as a valve between the esophagus and stomach⁴. Acid reflux is common and affects many people worldwide, impacting their life quality if not treated⁵.

Occasional acid reflux is normal, especially after eating a big or spicy meal⁵. But if it happens often or doesn’t go away, it could be GERD. GERD is a chronic acid reflux that can cause serious problems like esophagitis, esophageal stricture, and Barrett’s esophagus. This last one is a precancerous condition that raises the risk of esophageal cancer⁴.

Understanding the Causes of Acid Reflux

Many things can lead to acid reflux and GERD, like a hiatal hernia, being overweight, pregnancy, and certain habits⁶. Knowing what causes acid reflux helps in managing and preventing it.

• Hiatal hernia: This is when part of the stomach bulges through the diaphragm, weakening the LES and making acid reflux more likely⁶.
• Obesity: Being overweight puts pressure on the stomach and weakens the esophageal sphincter, raising the risk of acid reflux⁶.
• Pregnancy: Hormonal changes and the growing baby can press on the stomach, relaxing the LES and causing acid reflux⁶.
• Lifestyle factors: Smoking, some foods and drinks, and eating habits can make acid reflux worse⁶.

Knowing what causes acid reflux helps people manage their symptoms and lower the risk of serious problems⁵.

“Acid reflux is a common condition that can be managed with a combination of lifestyle changes and medical treatment.”

Symptoms of Acid Reflux

Acid reflux, also known as gastroesophageal reflux disease (GERD), shows up in many ways⁷. Common signs include heartburn, a sour taste, regurgitation, nausea, and bloating⁷. Other signs are a dry cough, throat clearing, hoarseness, and even tooth enamel erosion⁷.

It can be a tough condition, with⁸ over 60 million American adults having heartburn at least once a month⁸. For pregnant women, it’s common by the third trimester due to hormonal changes⁸.

Don’t ignore acid reflux, as it can turn into a serious condition, gastroesophageal reflux disease (GERD)⁹. If not treated, GERD can cause inflammation, bleeding, and make swallowing hard⁹.

Recognizing the Symptoms

Acid reflux symptoms can be mild or severe and often include a burning chest sensation, known as heartburn⁷. Other signs are a sour taste, regurgitation, and chest pain at night⁷.

If these symptoms don’t go away or get worse, see a doctor⁹. Understanding acid reflux symptoms helps people take steps to manage it and find relief.

“Acid reflux is a common condition that can significantly impact an individual’s quality of life. Recognizing the symptoms and seeking appropriate treatment is crucial for managing this condition and preventing potential complications.”

Causes of Acid Reflux

Acid reflux, also known as gastroesophageal reflux disease (GERD), is a common issue. It happens when stomach contents, including acid, flow back into the esophagus¹⁰. This can be caused by a hiatal hernia, obesity, pregnancy, certain foods, and some medicines.

A hiatal hernia is a common cause of acid reflux¹¹. Pregnancy can also lead to acid reflux, especially in the third trimester, and it goes away after giving birth¹¹.

Certain foods and drinks can make acid reflux worse. These include alcohol, carbonated drinks, chocolate, citrus fruits, coffee, fatty or fried foods, tomatoes, garlic, onions, mint, and spicy foods¹¹¹². Smoking also raises the risk by harming the mucus membranes and making the LES muscle work less well¹¹¹².

Being overweight or obese is a big risk factor for acid reflux¹¹¹². Eating a big meal and then lying down can also cause acid reflux. Snacking before bed and some medicines like aspirin or ibuprofen can make it worse¹¹¹².

“Certain foods and drinks can trigger heartburn and acid reflux, like coffee, tomatoes, alcohol, chocolate, and fatty or spicy foods.”¹²

Knowing what causes acid reflux helps in finding the right treatment. By avoiding these triggers, people can reduce or prevent acid reflux symptoms.

Hiatal Hernia and Acid Reflux

A hiatal hernia happens when part of the stomach bulges through the diaphragm. This can lead to acid reflux¹³. It can weaken the muscle at the bottom of the esophagus, letting stomach acid flow back up¹³. Symptoms include heartburn, chest pain, fatigue, and trouble swallowing¹³.

Small hiatal hernias might not cause any symptoms and are often found by accident during check-ups¹³. But bigger ones can cause food and acid to flow back up, leading to discomfort¹⁴. Sometimes, surgery is needed to fix these problems¹⁴.

Hiatal hernias can be caused by age, being overweight, or previous surgeries¹⁴. People over 50 are more likely to get one due to aging¹⁴. Being overweight also increases the risk because it puts pressure on the stomach muscles¹⁴.

Certain activities and health issues can also raise the chance of getting a hiatal hernia¹⁵. Activities like coughing a lot, straining during bowel movements, or lifting heavy can put pressure on the stomach muscles¹⁵. People born with a big hiatus are more likely to get a hiatal hernia too¹⁴.

If you have ongoing symptoms, see a doctor right away¹⁴. Not all hiatal hernias need treatment right away, but getting help can prevent serious problems like chronic acid reflux¹⁵.

“Hiatal hernias are a common condition, and while many people with this condition may not experience any symptoms, it is important to be aware of the potential risks and seek medical attention if necessary.”

Obesity and Acid Reflux

Being overweight is a big risk for acid reflux and GERD¹⁶. It puts pressure on the stomach, which can weaken the LES. This makes it relax too much, letting stomach acid flow back up¹⁷. Even a little extra weight can increase the risk of GERD¹⁷.

Fat tissue makes estrogen, which relaxes the LES more. This can cause a hiatal hernia and more acid reflux¹⁶. Carrying extra weight around the stomach puts more pressure. This can lead to a hiatal hernia and more acid reflux¹⁸. Obesity can also mean higher levels of pancreatic enzymes and bile, making stomach acid irritation worse¹⁸.

The Link Between Obesity and GERD

Studies show a strong link between obesity and GERD¹⁸. A 2003 study from Scandinavia found being overweight or obese makes GERD six times more likely¹⁸. Higher obesity levels are linked to more severe acid reflux symptoms¹⁸.

Even a bit of weight gain can up the risk of GERD¹⁸. A study in the New England Journal of Medicine found a clear link between BMI and GERD risk¹⁸.

Losing weight can really help with acid reflux¹⁷. Just a few pounds lost can ease heartburn and GERD symptoms¹⁷. Bariatric surgery, like Roux-en-Y gastric bypass, can also help those with a BMI of 35 or higher and diabetes lose weight and reduce GERD symptoms¹⁷.

Not all bariatric surgeries work the same for GERD. Gastric sleeve surgery might not be best for those with GERD or Barrett’s esophagus¹⁷. Choosing the right surgery can lead to fewer GERD symptoms after¹⁷.

Along with weight loss, quitting smoking and avoiding certain foods and drinks can also help manage GERD symptoms¹⁷¹⁶¹⁸.

Pregnancy and Acid Reflux

Pregnancy often leads to acid reflux, also known as GERD during pregnancy. This happens due to hormonal changes and increased pressure on the stomach from the growing fetus¹⁹²⁰²¹.

The growing uterus puts pressure on the stomach, making stomach contents flow back up into the esophagus²⁰. The hormone progesterone also relaxes the muscles in the body. This includes the muscle that separates the stomach from the esophagus, letting acid reflux²¹.

Acid reflux symptoms often start in the second trimester of pregnancy¹⁹. Women may feel heartburn, regurgitation, and a sour taste in their mouth, especially after eating big or fatty meals¹⁹²⁰.

• Symptoms of indigestion and heartburn during pregnancy are more common from 12 weeks onwards¹⁹.
• Indigestion may be more likely if you are very full while pregnant¹⁹.
• Smoking while pregnant can lead to indigestion, low birth weight, premature birth, and SIDS¹⁹.
• Alcohol consumption during pregnancy can cause indigestion and long-term harm to the baby¹⁹.

To manage acid reflux during pregnancy, women may use over-the-counter medications like antacids and alginates¹⁹. But, it’s crucial to talk to a healthcare provider before taking any medication. Some may not be safe with prenatal vitamins or could have other risks²⁰.

Acid reflux during pregnancy can be tough, but it usually goes away after the baby is born²¹. Until then, pregnant women can try to ease their symptoms by avoiding large meals, eating slowly, and raising the head of their bed²¹.

Lifestyle Factors Contributing to Acid Reflux

Some medical conditions can make acid reflux worse, but lifestyle choices can also play a big role. Smoking, eating certain foods, and poor eating habits can all make acid reflux symptoms worse. It’s important to know how these factors affect you to manage acid reflux better.

Smoking and Alcohol Consumption

Smoking is a big risk factor for acid reflux. It relaxes the muscle that keeps stomach acid down, letting it flow back up²². Smoking also lowers saliva production, which helps neutralize stomach acid. Drinking alcohol can also weaken this muscle and make more stomach acid, making reflux worse²².

Dietary Triggers

Some foods and drinks can make acid reflux worse. Citrus fruits, tomatoes, chocolate, mint, garlic, onions, and coffee are common culprits²³. A vegetarian diet might lower the risk of acid reflux, but eating more protein and fat can increase it²³. It’s key to find out which foods make your reflux worse and avoid them.

Eating Habits

How you eat can also affect acid reflux. Eating big meals, eating before bedtime, and lying down right after can make reflux worse²³. Drinking a lot of liquids, coffee, and strong tea can also make reflux worse, while vitamins and nutrients can help²³.

Changing your lifestyle can help manage acid reflux. This includes losing weight, quitting smoking, drinking less alcohol, and changing your diet²². By making these changes, you can reduce the impact of acid reflux on your health.

“Lifestyle changes are now seen as a first step in treating GERD because of the side effects of long-term PPI use.”²³

Complications of Chronic Acid Reflux

Occasional acid reflux is common, but long-term acid reflux, or GERD, can cause serious problems²⁵²⁶. These issues include inflammation in the esophagus, a condition called Barrett’s esophagus, and even esophageal cancer.

Esophageal Inflammation and Damage

Stomach acid can cause inflammation and irritation in the esophagus, known as esophagitis²⁶. This can lead to scarring and narrowing of the esophagus, making swallowing hard²⁶. If not treated, esophagitis can get worse.

Barrett’s Esophagus

Chronic acid reflux can change the esophageal lining to tissue like the intestine’s, known as Barrett’s esophagus²⁵²⁶²⁷. This condition raises the risk of esophageal cancer, especially adenocarcinoma²⁷.

Esophageal Cancer

Esophageal cancer is a serious issue from chronic acid reflux²⁵²⁷. GERD slightly increases the risk, and Barrett’s esophagus raises it more, especially with a family history²⁵²⁷. Symptoms of esophageal cancer are often late, making treatment tough²⁵.

Chronic acid reflux also affects dental health²⁶. Stomach acid can damage tooth enamel, causing decay and other dental problems²⁶.

Managing acid reflux with diet changes, losing weight, and quitting smoking, along with medication, can prevent these issues²⁵²⁶²⁷.

Diagnosing Acid Reflux

Gastroesophageal reflux disease (GERD) affects many people²⁸. It’s a chronic condition that needs accurate diagnosis. Healthcare providers use tests to find out if someone has acid reflux and GERD.

Endoscopy

An upper GI endoscopy looks at the upper GI tract, like the esophagus and stomach²⁹. It helps doctors see if there are any problems, like inflammation or a hiatal hernia, that cause acid reflux²⁸.

pH Monitoring

Esophageal pH monitoring uses a catheter or a wireless capsule to check for stomach acid in the esophagus²⁹. This test confirms GERD and checks if treatments work²⁹.

Manometry

Esophageal manometry checks how well the esophagus muscles work together³⁰. It’s important to rule out other conditions that might seem like GERD before surgery³⁰.

Doctors might also suggest a barium swallow test to look at how the esophagus moves and find any structural issues³⁰.

These tests help doctors give the right treatment for acid reflux and GERD²⁸. Sometimes, heartburn after eating or lying down is normal. But for those with GERD, symptoms can be mild or severe and vary a lot²⁸.

“Accurate diagnosis is key to effective management of acid reflux and GERD. Healthcare providers utilize a range of tests to identify the underlying causes and severity of the condition, ensuring the most appropriate treatment can be provided.”

Knowing how acid reflux and GERD are diagnosed helps people work with their doctors. Together, they can find the best way to manage this chronic condition²⁸²⁹³⁰.

Acid Reflux Medications

Managing acid reflux often means using different medications. There are both over-the-counter and prescription options. It’s key to know how they work and their possible side effects.

Over-the-Counter Acid Reflux Medications

Antacids like Tums, Rolaids, and Maalox neutralize stomach acid. They help with heartburn and mild acid reflux symptoms³¹. But, they might cause constipation, diarrhea, and change bowel movement color.

H2 blockers, such as Pepcid AC and Zantac 360, cut down stomach acid production. This gives longer relief³¹. The Zantac brand was recalled in 2020 because it had a cancer-causing agent.

Proton pump inhibitors (PPIs), like Nexium 24HR, Prevacid 24HR, and Prilosec OTC, reduce acid production a lot. They help with severe acid reflux symptoms³¹.

Prescription Acid Reflux Medications

For acid reflux that doesn’t go away or is very bad, doctors might prescribe stronger drugs. Prescription H2 blockers, like Tagamet HB, are stronger than what you can buy over-the-counter³¹.

Prescription PPIs, including Nexium, Prevacid, Prilosec, and Protonix, can control acid production even better³¹. Side effects of H2 blockers and PPIs might include headache, diarrhea, stomach pain, bloating, constipation, nausea, and gas.

If over-the-counter drugs don’t help or if you need them for more than two weeks, see a healthcare provider³¹. Some drugs, like antibiotics, bisphosphonates, and nonsteroidal anti-inflammatory drugs, can make acid reflux worse³².

Choosing the right medication and following the dosage and duration is key to managing acid reflux well. Doctors can help pick the best treatment based on your symptoms, health history, and how you react to different drugs³³³¹³².

Surgical Treatment for Acid Reflux

If lifestyle changes and medicines don’t help with acid reflux, or if there’s a risk of Barrett’s esophagus, surgery might be an option³⁴. Common surgeries for GERD include the LINX procedure and fundoplication.

The LINX procedure uses magnetic beads to strengthen the lower esophageal sphincter and stop acid reflux³⁴. This surgery is minimally invasive and has good results. Most people don’t need GERD meds and stay symptom-free for five years³⁴. But, it’s not for everyone, especially those with big hiatal hernias³⁴.

Fundoplication wraps the stomach around the esophagus to keep acid from flowing back up³⁵. This surgery, like the Nissen or Toupet methods, often means no more GERD meds³⁴. People usually feel better within a week³⁴. Some might have side effects like swallowing issues, bloating, and gas, but these usually go away in a few weeks³⁴.

Surgery might be suggested if medicines don’t work well or if there’s a big risk of serious esophageal problems³⁵. Before surgery, you might need blood tests, esophageal manometry, pH monitoring, upper endoscopy, and X-rays to check the reflux and any other issues³⁵. Laparoscopic fundoplication is the top choice for GERD surgery because it helps you recover faster and has fewer risks³⁶.

Surgery can really help with acid reflux for many people. But, it’s important to talk about the risks and benefits with your doctor to see what’s best for you³⁵.

Lifestyle Changes to Manage Acid Reflux

Changing your lifestyle can help manage acid reflux and GERD symptoms³⁷. These changes focus on the main causes of reflux. They offer long-term relief and protect the esophagus from further damage.

Dietary Adjustments

First, find and avoid foods that trigger acid reflux³⁷. Foods like coffee, tea, and spicy foods can cause problems. Eating foods that are good for GERD can make a big difference.

• Eat more fiber-rich foods like whole grains and vegetables to prevent overeating and reduce heartburn risk³⁸.
• Try alkaline foods like bananas and melons to balance stomach acid and ease acid reflux³⁸.
• Drink watery foods like celery and cucumber to help dilute stomach acid and ease heartburn³⁸.
• Add ginger to your diet for its anti-inflammatory effects and to help with heartburn³⁸.

Portion Control and Timing

Changing how you eat can also help with acid reflux³⁷. Eating big meals can put pressure on the valve between the stomach and esophagus. Eating smaller, more often can help.

Don’t eat close to bedtime and skip snacks before sleeping to stop stomach acid from flowing up³⁷. Raising your bed head can also help with nighttime reflux³⁷.

Weight Management and Lifestyle Factors

Keeping a healthy weight is key for managing acid reflux³⁷. Being overweight can affect the valve in your esophagus and cause reflux. Losing weight can help reduce heartburn for many people³⁹.

Smoking and drinking too much alcohol can also cause acid reflux³⁷. Nicotine can weaken the muscle that keeps stomach acid down, while alcohol can make reflux worse³⁷. Quitting smoking can improve GERD symptoms³⁹.

Living a healthy life, eating right, exercising, and avoiding bad habits can cut down on acid reflux³⁷. If symptoms don’t get better, seeing a gastroenterologist is a good idea to find the right treatment³⁸.

“The management of GERD involves a step-by-step approach guided by a medical professional, taking into account the individual’s symptom severity.”³⁷

Acid Reflux in Babies and Children

Acid reflux and gastroesophageal reflux disease (GERD) are common in infants and children. Sometimes, babies spit up, which is normal. But if it happens a lot or is very bad, it might be serious and needs a doctor⁴⁰.

Reflux is normal in babies and happens often. It gets less common as they grow older. After 18 months, it’s rare for reflux to keep happening⁴⁰. In some cases, it can cause weight loss or slow growth, which means there might be a bigger health issue⁴⁰.

Some babies are more likely to have reflux. This includes those born too early, with lung or brain conditions, or who had esophagus surgery before⁴⁰. Most of the time, reflux in babies goes away by itself. But if it happens a lot, it might lead to GERD later on⁴⁰.

In older kids, having reflux as a baby might mean they’ll get GERD later⁴¹. Signs of GERD include being very fussy, not sleeping well, eating poorly, wheezing, hoarseness, and bad breath⁴². If a child shows these signs, they should see a doctor. GERD in kids can cause serious problems if not treated⁴².

There are ways to help with reflux in babies. Changing the diet, burping more, and having them sleep on their back can help⁴². If these don’t work, a doctor might prescribe medicine. Surgery is rare, and most babies outgrow it by 18 months⁴².

Parents should watch for reflux symptoms in their kids and get help if it doesn’t get better or gets worse. With the right care, most kids with acid reflux or GERD can feel better and avoid serious problems⁴².

The Connection Between Asthma and Acid Reflux

Asthma and acid reflux, or GERD, are closely linked⁴³. Doctors have found a strong link between asthma and heartburn. If you have asthma, you’re more likely to have heartburn⁴³. The link involves stomach acid affecting the airways.

GERD may show up if asthma symptoms start in adulthood or get worse after eating or activity⁴³. Some asthma medicines, like Prednisone and albuterol, can make acid reflux worse⁴³.

Treating acid reflux can help improve asthma symptoms⁴³. Over-the-counter drugs like antacids and proton-pump inhibitors can help manage GERD⁴³. Changing your lifestyle, such as raising your bed, eating smaller meals, and quitting smoking, can also help⁴³.

The Prevalence of GERD in Asthma Patients

Research shows asthma patients are more likely to have GERD⁴⁴. About 15% to 65% of asthma patients use proton pump inhibitors for GERD and severe asthma⁴⁴. Yet, a 2009 study found PPIs didn’t help severe asthma attacks much⁴⁴.

Strategies for Managing GERD-Induced Asthma

For kids, avoiding acid reflux means burping them during feeding and keeping them upright after⁴⁴. Adults can manage GERD by avoiding trigger foods and eating smaller meals⁴⁴.

Other ways to ease asthma symptoms include exercise and certain foods⁴⁴. Symptoms of GERD-induced asthma include wheezing and coughing⁴⁴. Inhalers can help, but they don’t fix the root GERD problem⁴⁴.

GERD breathing problems are often treated with medication and lifestyle changes⁴⁴. If symptoms don’t get better, you should see a doctor⁴⁴.

The Link Between Laryngopharyngeal Reflux and Asthma

About half of asthma patients also have GERD⁴⁵. Doctors look for GERD as a cause of asthma in adults or when asthma doesn’t get better⁴⁵.

Managing asthma from laryngopharyngeal reflux means changing your lifestyle and possibly taking medication⁴⁵. Surgery can also help⁴⁵.

Conclusion

Acid reflux and GERD affect many people, with up to 27.8% of Americans dealing with them⁴⁶. It’s important to know the causes, symptoms, and how to get help. This is key to managing acid reflux and lowering the risk of serious problems.

Being overweight, smoking, some medicines, and what we eat can make acid reflux worse⁴⁷. Changing these things can help. For example, losing weight, quitting smoking, and eating better can ease symptoms and prevent more serious issues like esophagitis and esophageal cancer⁴⁷.

For those with ongoing or severe acid reflux, there are many treatment options⁴⁷. This includes both over-the-counter and prescription drugs, and sometimes surgery. Working with doctors and taking action can help manage acid reflux. This keeps the digestive system healthy and improves life quality⁴⁸.
