What Causes Acid Reflux Disease: Symptoms and Causes

Reviewed by Arturo Gonzalez, M.D.

Acid reflux is a prevalent condition that affects millions globally, causing discomfort and affecting daily life. If you’ve ever felt a burning sensation in your chest after consuming a meal or experienced a sour taste lingering in your mouth, you’re likely familiar with this troubling condition. Gaining a clear understanding of the symptoms and underlying causes of acid reflux is crucial for managing and effectively treating it.

Read on to learn all about acid reflux, its symptoms, causes, and how you can manage it through lifestyle modifications and medical interventions. By becoming informed about this condition, you can take proactive steps to alleviate its impact on your life.

What Is Acid Reflux?

Acid reflux occurs when the acid from the stomach flows backward into the esophagus, the tube that connects your mouth to your stomach. This backward flow of acid can irritate and inflame the lining of your esophagus, resulting in a burning sensation commonly referred to as heartburn. This condition can occur occasionally in many people, but when it becomes frequent, it requires attention.

The Difference Between Acid Reflux and GERD

Acid reflux itself is a common occurrence that many people experience occasionally. However, when acid reflux becomes frequent and severe, it can develop into gastroesophageal reflux disease (GERD), a chronic digestive disorder. GERD occurs when acid reflux happens more than twice a week, leading to inflammation and potential damage to the esophagus. Understanding the distinction between occasional acid reflux and GERD is essential for appropriate treatment and management.

While occasional acid reflux may not necessitate significant medical intervention, GERD requires a more comprehensive approach, as it can lead to complications such as esophagitis, Barrett’s esophagus, and even esophageal cancer if left untreated. Recognizing the severity and persistence of symptoms is crucial for determining the appropriate course of action and seeking medical guidance when needed.

Common Symptoms of Acid Reflux

Recognizing the symptoms of acid reflux is the first step in managing it effectively. Some common signs that may indicate the presence of acid reflux include:

• Heartburn: This is a burning sensation in the chest that often occurs after eating and may be more pronounced at night. It can be uncomfortable and persistent, disrupting daily activities and sleep.
• Regurgitation: This involves a sour or bitter-tasting acid backing up into your throat or mouth, leaving an unpleasant taste and sensation.
• Bloating: Feeling full or bloated even when you haven’t eaten much can be a sign of acid reflux, as excess gas and acid build up in the stomach.
• Burping: Frequent burping can bring up stomach acid, contributing to the discomfort associated with acid reflux.
• Nausea: Feeling sick to your stomach after meals can be a sign of acid reflux, as the stomach acid irritates the digestive tract.
• Hiccups: Persistent hiccups that don’t go away easily may be linked to acid reflux, as the irritation in the esophagus can trigger the diaphragm.
• Sore Throat: A chronic sore throat, hoarseness, or a lump-like feeling in the throat can result from the irritation caused by acid reflux.

GERD Symptoms

GERD symptoms are similar to those of acid reflux but tend to be more severe and persistent. They can include:

• Chronic Heartburn: Persistent heartburn that doesn’t go away with over-the-counter medications can indicate GERD, requiring medical evaluation and treatment.
• Difficulty Swallowing: A feeling of food sticking in the throat or a narrowing of the esophagus can make swallowing difficult and painful.
• Chest Pain: Severe chest pain that might mimic a heart attack can occur with GERD and should be evaluated by a healthcare professional to rule out cardiac issues.
• Chronic Cough: A dry cough that lingers and is often worse at night can be associated with GERD, as the acid irritates the throat and respiratory tract.

What Causes Acid Reflux?

Understanding the causes of acid reflux can help in preventing its occurrence and managing it effectively. Several factors can contribute to the development of acid reflux:

Diet and Lifestyle

Diet and lifestyle choices play a significant role in the onset and exacerbation of acid reflux:

• Eating Large Meals: Overeating can put pressure on the stomach, leading to acid reflux. Consuming smaller, more frequent meals can help alleviate this pressure.
• Lying Down After a Meal: Going horizontal too soon after eating can cause the acid to flow back up, as gravity no longer helps keep the acid in the stomach. It’s advisable to remain upright for at least three hours after eating.
• Certain Foods and Drinks: Spicy foods, citrus, tomatoes, chocolate, mint, garlic, onions, and caffeinated or alcoholic beverages can trigger reflux. Identifying and avoiding these triggers can be beneficial.
• Smoking: Smoking weakens the lower esophageal sphincter, allowing acid to escape more easily into the esophagus. Quitting smoking can significantly improve symptoms.
• Being Overweight: Extra weight can put pressure on the abdomen, pushing up the stomach and causing acid to back up. Weight loss can reduce this pressure and alleviate symptoms.

Medical Conditions

Certain medical conditions can increase the risk of acid reflux:

• Hiatal Hernia: A condition where part of the stomach pushes through the diaphragm into the chest cavity can affect the function of the lower esophageal sphincter, leading to reflux.
• Pregnancy: Hormonal changes and pressure from the growing fetus can lead to reflux, especially in the later stages of pregnancy.
• Delayed Stomach Emptying: Also known as gastroparesis, this condition occurs when the stomach takes longer to empty, increasing the risk of reflux as the stomach contents linger longer.

Managing Acid Reflux

While medication can offer relief, lifestyle changes are often the first line of defense against acid reflux. Adopting healthier habits can significantly reduce symptoms and improve quality of life. Here are some evidence-based strategies for managing acid reflux:

Dietary Adjustments

• Eat Smaller Meals: Instead of three large meals, try five or six smaller ones throughout the day to reduce the pressure on the stomach.
• Avoid Trigger Foods: Identify and avoid foods that trigger your symptoms, and keep a food diary to track your triggers.
• Stay Upright After Meals: Waiting at least three hours after eating before lying down or going to bed can prevent acid from flowing back into the esophagus.
• Chew Gum: Chewing gum increases saliva production, which can help neutralize stomach acid and improve digestion.

Lifestyle Changes

• Lose Weight: If you’re overweight, losing even a small amount can reduce pressure on your stomach and alleviate symptoms.
• Elevate Your Head While Sleeping: Use a wedge pillow or elevate the head of your bed to keep acid down at night, reducing nighttime symptoms.
• Quit Smoking: Smoking cessation can improve symptoms and overall health, reducing the risk of acid reflux and other related health issues.

Medical Treatments

When lifestyle changes aren’t enough, medical treatments might be necessary. It’s important to consult with a healthcare provider for options such as:

• Antacids: Over-the-counter medications that neutralize stomach acid can provide quick relief for mild symptoms.
• H2 Blockers: These medications reduce acid production and provide longer relief than antacids, making them suitable for more persistent symptoms.
• Proton Pump Inhibitors (PPIs): More potent acid blockers that help heal the esophagus and provide long-term relief for chronic acid reflux.
• Surgery: In severe cases, surgical options like fundoplication might be considered to strengthen the lower esophageal sphincter and prevent acid reflux.

When to Seek Medical Advice

While occasional acid reflux is common, persistent or severe symptoms warrant a visit to a healthcare provider. If you experience frequent heartburn, difficulty swallowing, or unexplained weight loss, it’s important to consult Dr. Arturo Gonzalez to rule out more serious conditions and receive appropriate treatment. 

Conclusion

Acid reflux is a manageable condition with the right approach. By understanding the symptoms and causes, making informed dietary and lifestyle changes, and seeking medical advice when necessary, you can take control of your digestive health and improve your quality of life.
