Why Does My Stomach Burn? Common Causes and How to Fix It

Experiencing a burning sensation in your stomach is a common complaint that many people face at some point in their lives. It can vary from a mild discomfort to a severe, painful experience that affects daily activities. This burning feeling may be localized in the upper abdomen or may radiate to the chest. While stomach burning may be temporary for some, for others, it can become a recurring problem that demands attention. Understanding the causes and effective solutions can significantly improve your quality of life.

This article explores the common causes of stomach burning, how to identify them, and offers solutions for relief. Additionally, it delves into how food sensitivities and intolerances could be the hidden culprits behind this discomfort. You’ll also find out about relevant tests, like the Food Sensitivity Test and Food Intolerance Test, and how they can help you determine triggers for your stomach issues.

Understanding the Sensation of Stomach Burning

Before diving into the causes of stomach burning, it's essential to understand the sensation. A stomach burn can be described as a sharp, warm, or painful feeling in the upper abdomen, often accompanied by nausea, bloating, or a sour taste in the mouth. Some individuals might feel this burning sensation after eating or drinking certain foods or beverages, especially acidic or spicy ones.

This discomfort can stem from irritation of the stomach lining or other gastrointestinal issues. When the stomach lining is inflamed or when gastric acids come in contact with sensitive tissues, it can cause a burning sensation. Understanding the root cause of the burning is key to finding the most effective treatment.

Common Causes of Stomach Burning

Gastroesophageal Reflux Disease (GERD)

One of the most common causes of stomach burning is Gastroesophageal Reflux Disease (GERD). GERD occurs when stomach acid or bile irritates the food pipe (esophagus), causing heartburn and a burning sensation in the chest or upper abdomen. When acid leaks into the esophagus, it leads to a feeling of discomfort or a sour taste in the mouth.

Symptoms include:

  • Burning sensation in the chest or stomach

  • Regurgitation of food or sour liquid

  • Difficulty swallowing

  • Coughing, wheezing, or sore throat

If you experience these symptoms frequently, GERD could be the culprit. Treatment options typically include antacids, H2 blockers, or proton pump inhibitors (PPIs), which work to reduce acid production and soothe the esophagus. Additionally, lifestyle changes such as avoiding spicy foods, chocolate, caffeine, and alcohol can help reduce GERD symptoms.

Peptic Ulcers

Another potential cause of stomach burning is peptic ulcers. These are open sores that develop on the lining of the stomach or the upper part of the small intestine. The most common cause of ulcers is an infection with the bacterium Helicobacter pylori (H. pylori), though regular use of nonsteroidal anti-inflammatory drugs (NSAIDs) can also lead to ulcer formation.

Symptoms include:

Peptic Ulcers
  • Burning or gnawing sensation in the stomach

  • Pain that worsens when the stomach is empty

  • Nausea or vomiting

  • Loss of appetite or weight loss

Peptic ulcers can be treated with antibiotics (for H. pylori infection) and medications to reduce stomach acid. Avoiding NSAIDs and alcohol may also help in preventing further irritation.

Food Sensitivity and Food Intolerances

Food sensitivities and intolerances are another prevalent cause of stomach burning, especially when consuming certain foods that the body has difficulty digesting. Food sensitivities or intolerances can trigger stomach discomfort, bloating, and a burning sensation. Common intolerances include lactose intolerance, gluten intolerance, and fructose malabsorption.

  • Lactose intolerance occurs when your body lacks the enzyme lactase needed to break down lactose, the sugar found in dairy products. This leads to digestive discomfort, bloating, and stomach cramps.

  • Gluten intolerance (or non-celiac gluten sensitivity) is when the body reacts negatively to gluten, a protein found in wheat, barley, and rye. It can cause abdominal pain, bloating, and burning sensations in the stomach.

  • Fructose malabsorption is a condition where the body cannot absorb fructose properly, leading to digestive issues.

To identify which food may be the cause of your symptoms, an At Home Food Sensitivity Test or Food Sensitivity Test Kit can be incredibly helpful. These tests can provide insights into which foods are triggering your stomach discomfort. A Gluten Sensitivity Test and a Lactose Intolerance Test can specifically help identify intolerances to these substances.

For individuals suffering from food sensitivities, managing symptoms often involves eliminating or reducing the intake of problematic foods. In some cases, individuals may find relief by consuming enzyme supplements that aid digestion.

Stress and Anxiety

Stress and anxiety can also contribute to stomach discomfort. The body’s fight-or-flight response activates when under stress, which can alter gut function and lead to stomach burning. Stress can increase acid production in the stomach, contributing to symptoms like heartburn and stomach irritation.

Solutions include:

Stress and Anxiety
  • Stress management techniques such as mindfulness, deep breathing exercises, and yoga.

  • Regular physical activity to help reduce anxiety and tension.

  • Seeking professional help for managing chronic stress or anxiety disorders.

Medications

Certain medications, especially nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and aspirin, can irritate the stomach lining and cause a burning sensation. Other medications, including antibiotics, steroids, and blood thinners, may also contribute to stomach discomfort. If you suspect your medications are causing your symptoms, consult your healthcare provider about potential alternatives or adjustments.

Alcohol Consumption

Excessive alcohol intake is another common cause of stomach burning. Alcohol can irritate the stomach lining, increase stomach acid production, and slow down the digestive process. People who consume alcohol regularly may experience symptoms of acid reflux or gastritis, leading to a burning sensation.

To minimize discomfort, reducing alcohol intake or avoiding it altogether can alleviate symptoms. Additionally, drinking plenty of water to stay hydrated may help mitigate some of the stomach irritation caused by alcohol.

When to Seek Medical Attention

While most cases of stomach burning are temporary and can be managed at home, there are instances when medical attention is necessary. If you experience any of the following symptoms, it's important to consult a healthcare provider:

  • Severe or persistent stomach pain

  • Vomiting blood or black, tarry stools

  • Unexplained weight loss or difficulty swallowing

  • A new or worsening burning sensation in the stomach

These could be signs of more serious conditions such as ulcers, gastrointestinal bleeding, or even stomach cancer.

Home Remedies and Self-Care Options

While it’s always best to seek medical advice for recurring or severe symptoms, there are several home remedies and self-care options that can help alleviate mild stomach burning:

Home Remedies and Self-Care Options

Dietary Adjustments

  • Avoid spicy, fatty, and fried foods, as they can irritate the stomach lining and exacerbate burning sensations.

  • Incorporate more fiber-rich foods, such as fruits, vegetables, and whole grains, to support digestion.

  • Smaller, more frequent meals may help reduce acid production and prevent irritation.

Hydration

Staying well-hydrated is essential for overall digestive health. Drinking water can help dilute stomach acid and wash down irritants, alleviating discomfort.

Over-the-counter Remedies

  • Antacids such as Tums or Rolaids can neutralize stomach acid and provide quick relief from burning sensations.

  • H2 blockers and proton pump inhibitors (PPIs) are available over the counter and can reduce acid production in the stomach.

Lifestyle Changes

  • Avoid lying down immediately after meals to prevent acid reflux.

  • Elevate the head of your bed if you experience burning at night to prevent acid from flowing back into the esophagus.

  • Wear loose-fitting clothing to reduce pressure on your stomach.

Long-Term Management Strategies for Stomach Burning

If stomach burning is a recurring issue, making long-term changes to your diet, lifestyle, and stress management practices is essential. In addition, seeking professional advice from a gastroenterologist can help identify underlying conditions that may require specific treatment.

A Food Sensitivity Test or Gluten Intolerance Test can be valuable tools in determining whether food sensitivities or intolerances are contributing to your symptoms. Testing for lactose intolerance and gluten sensitivity can help pinpoint problematic foods and guide dietary changes.
