Acid Reflux Explained: Causes and Heartburn Link

If you’ve ever experienced a burning feeling in your chest after eating spicy foods or when lying down, you may have noted what heartburn is all about. But what causes this unpleasant feeling? Generally, it is due to a common condition referred to as acid reflux. Knowing what is acid reflux, its causes, and how it leads to heartburn will help you manage your symptoms, and positively impact your health and well-being.

This blog will discuss acid reflux causes, the difference between acid reflux and heartburn, the symptoms of acid reflux, and answer some commonly asked questions.

What Is Acid Reflux?

Acid reflux occurs when the stomach acid comes back up into the esophagus-- the esophagus is the tube that connects your mouth to your stomach. The lower esophageal sphincter (LES) is a valve that keeps stomach acid from flowing in the opposite direction. If this valve is weak or relaxes when it should not, acid flows into the esophagus and irritates it.

This backward flow of acid is the primary contributor to the unpleasant symptom of heartburn. However, acid reflux is not solely about heartburn; over time it could lead to more serious complications than, including esophagitis or Barrett's esophagus.

Acid Reflux Causes: Why Does It Happen?

Knowing acid reflux causes can help you minimize episodes of reflux, which is pertinent to your healthcare. Here are some common reasons reflux occurs:

• Weak or Relaxed LES: If the valve doesn't close tight enough, acid can move up.
• Hiatal Hernia: A condition where part of the stomach pushes through the diaphragm into the chest, weakening the LES.
• Obesity: Weight can increase pressure on the stomach which can make the acid reflux into the esophagus.
• Diet and Lifestyle: Fatty Foods, chocolates, caffeinated beverages, spicy food, or alcohol can trigger reflux.
• Smoking: Affects the LES and increases acid secretion.
• Pregnancy: Hormones increase abdominal pressure, which can or will cause reflux.
• Certain Medications: Some drugs like aspirin, ibuprofen, and muscle relaxants may relax the LES.

What Causes Heartburn and Its Relation to Acid Reflux?

Heartburn is the most recognized symptom of acid reflux. It is described as unrelenting burning pain that is behind the breastbone and rising swiftly toward your throat. The reason for this pain is the acidic content of the stomach is irritating the lining of the esophagus.

While many tend to use the two terms interchangeably, note that acid reflux and heartburn/GERD are related but do not mean the same thing. Acid reflux is the backward movement of acid into the esophagus; Heartburn is experienced sensation/symptom to some degree depending on the acid irritation.

Symptoms of Acid Reflux

Recognizing the symptoms of acid reflux can help you get treatment sooner. Symptoms can be mild to severe and can include:

• A burning feeling in your chest (heartburn) especially after eating or when bending overRegurgitation of sour-tasting or bitter-tasting acid going into your throat or mouth
• Even though food may get stuck in the esophagus or feel as if it is stuck
• Chronic cough or throat clearing
• Hoarseness or sore throat, especially when you wake up in the morning
• Sensation of a lump in your throat

If you have symptoms of acid reflux more than two times a week, it could be diagnosed as Gastroesophageal Reflux Disease (GERD), a chronic version of acid reflux.

Difference Between Acid Reflux and Heartburn

Many ask about the difference between them since they often occur together. Here’s a simple explanation:

Aspect	Acid Reflux	Heartburn
What it is	The backward flow of stomach acid into the esophagus	The burning sensation caused by acid reflux
Cause	Weak LES, lifestyle, medical conditions	Acid irritating esophageal lining
Symptoms	Regurgitation, chest discomfort, throat issues	Burning pain behind the sternum, sometimes sour taste
Can occur independently	Often can’t be felt unless it causes heartburn	Occurs as a result of acid reflux irritation

In short, acid reflux is the condition, and heartburn is the most common symptom describing that condition’s discomfort.

How to Manage Acid Reflux and Heartburn

Preventing acid reflux is only about making lifestyle changes and dietary changes:

• Eat smaller meals and avoid lying down right afterward
• Avoiding trigger foods (spicy, fatty, acidic foods).
• Maintaining a healthy weight
• Quit smoking and reduce your alcoholic beverages
• Raise the head of your bed if your symptoms worsen when you sleep at night.
• Loose-fitting clothing

If lifestyle changes are not enough to help you, medications may be the next step, but you should seek the guidance of a healthcare provider to diagnose you and develop a treatment plan that is right for you.

Understanding what is acid reflux and how it causes heartburn helps you recognize symptoms and manage the condition better. Acid reflux occurs when stomach acid flows back into the esophagus due to a weakened LES or other factors, leading to the burning chest pain called heartburn. By adopting healthy habits, adjusting your diet, and knowing the acid reflux causes, you can reduce discomfort and protect your digestive health.
