Why does it feel like my insides are burning? Understanding the causes

4 min read

According to Verywell Health, indigestion affects 20% of the population, often causing a burning sensation in the stomach. If you have ever asked, "Why does it feel like my insides are burning?" you are not alone, and the potential causes range from simple dietary issues to more complex medical conditions.

Quick Summary

The internal burning sensation can stem from various conditions, including acid reflux, gastritis, ulcers, and anxiety-related nerve sensitivities, all of which require careful consideration to pinpoint the exact cause and determine the appropriate treatment.

Key Points

  • Digestive Causes: Conditions like GERD, gastritis, and peptic ulcers often cause an internal burning sensation due to acid irritation and inflammation of the digestive tract lining.

  • Nervous System Link: Anxiety and stress can heighten nerve sensitivity, triggering a physical response that feels like internal burning or tingling.

  • Serious Symptoms: Seek immediate medical attention for severe, persistent burning, difficulty swallowing, or signs of internal bleeding like black, tarry stools.

  • Lifestyle Changes: Simple adjustments like diet modification, stress management, and avoiding lying down after eating can offer relief for milder cases.

  • Underlying Conditions: Other medical issues, including pancreatitis and certain infections, can also be responsible for this pain.

  • Professional Guidance: A healthcare provider can provide an accurate diagnosis and treatment plan, especially if at-home remedies are not effective or symptoms are severe.

Common Digestive Causes

The most common culprits behind an internal burning sensation are issues affecting the digestive tract. The esophagus, stomach, and intestines are all lined with sensitive tissues that can become irritated, leading to pain often described as a burning or gnawing feeling.

Gastroesophageal Reflux Disease (GERD)

This is a chronic condition where stomach acid frequently flows back into the tube connecting your mouth and stomach (esophagus). The frequent exposure to stomach acid irritates the esophageal lining, causing a burning sensation in the chest, known as heartburn. Other symptoms include a sour taste in the mouth, chest pain, and difficulty swallowing.

Gastritis

Gastritis is the inflammation of the stomach lining. This inflammation is often the result of an H. pylori bacterial infection, regular use of certain pain relievers (NSAIDs), or excessive alcohol consumption. Besides the burning feeling in the upper abdomen, gastritis can also cause nausea, vomiting, and a feeling of fullness after eating.

Peptic Ulcers

Peptic ulcers are open sores that develop on the inside lining of your stomach and the upper part of your small intestine. A burning stomach pain is a hallmark symptom, though you might also experience bloating, a feeling of fullness, and intolerance to certain foods.

Inflammatory Bowel Disease (IBD)

In some cases, chronic inflammation of the digestive tract, such as Crohn's disease or ulcerative colitis, can cause abdominal pain that feels like burning. For many patients, pain can persist even when the disease activity is low, suggesting nerve sensitivity is also at play.

Systemic and Nervous System Causes

Sometimes, the burning sensation isn't a digestive problem at all but is related to the nervous system or other systemic issues.

Anxiety and Stress

Anxiety can trigger your body's 'fight or flight' response, causing a heightened sensitivity in the nervous system. This increased nerve activity and the release of stress hormones can lead to sensations such as tingling, numbness, or burning in various parts of the body, including internally. Stress can also exacerbate pre-existing digestive conditions like IBS and GERD.

Neuropathy

Peripheral neuropathy is a condition where the nerves carrying signals from the brain and spinal cord are damaged. This can result in a sharp, throbbing, or burning pain, which might be perceived as an internal burning sensation. Conditions like diabetes can cause neuropathy, and sometimes IBD patients may also experience this type of pain.

Other Medical Conditions

Several other health issues can lead to an internal burning sensation, including:

  • Pancreatitis: Inflammation of the pancreas can cause a dull or burning sensation in the upper abdomen that radiates to the back and worsens after eating.
  • Kidney Infection: A bacterial infection in the kidneys can cause symptoms like fever, chills, back pain, and a burning sensation during urination.
  • Food Poisoning: In severe cases, food poisoning can cause neurologic symptoms such as weakness, blurry vision, and abnormal sensations like burning or tingling.

Comparison of Common Causes

Feature Digestive Issues (e.g., GERD, Gastritis) Systemic/Nervous Issues (e.g., Anxiety, Neuropathy)
Primary Cause Irritation or inflammation of the digestive tract lining, often by acid, bacteria, or inflammation Heightened nerve sensitivity and systemic stress response
Typical Location Upper abdomen, chest, or stomach area Can be widespread or specific, often in hands and feet for neuropathy but perceived internally with anxiety
Associated Symptoms Nausea, bloating, vomiting, heartburn, burping Rapid heartbeat, sweating, muscle tension, restlessness, changes in mental state
Triggers Certain foods, alcohol, smoking, NSAIDs Stress, panic attacks, high-anxiety situations
Alleviating Factors Antacids, dietary changes, smaller meals Deep breathing, meditation, stress management techniques

When to Seek Medical Attention

While some burning sensations can be managed at home, others require prompt medical evaluation. It's important to consult a healthcare professional if:

  1. The burning sensation is severe, persistent, or interferes with eating and sleeping.
  2. You experience accompanying symptoms like difficulty swallowing, unexplained weight loss, or persistent nausea.
  3. You pass black, tarry stools or vomit blood (resembling coffee grounds), which can indicate internal bleeding.
  4. You feel dizzy, lightheaded, or faint, which may indicate significant blood loss.
  5. You have severe chest pain, shortness of breath, or an irregular heartbeat, as this can mimic a digestive issue but could be heart-related.

Actionable Steps for Relief

If your symptoms are mild and occasional, you can take several steps to find relief at home. Always consult a doctor before starting a new regimen.

  1. Adjust your diet. Avoid common trigger foods such as fatty or spicy meals, caffeine, alcohol, and acidic foods. Consider a bland diet for a few days to see if symptoms improve.
  2. Eat smaller, more frequent meals. This can reduce the amount of acid in your stomach at any one time and prevent overfilling.
  3. Manage stress. Techniques like deep breathing, meditation, and yoga can help manage anxiety-related symptoms.
  4. Avoid lying down after eating. Wait at least two to three hours after a meal before lying down or going to bed, as this can worsen reflux.
  5. Stop smoking. Smoking can significantly worsen digestive issues like GERD and peptic ulcers.
  6. Maintain a healthy weight. Excess weight puts additional pressure on your abdomen, which can push stomach acid into the esophagus.

For more detailed information on managing symptoms, the National Institute of Diabetes and Digestive and Kidney Diseases provides reliable resources on various gastrointestinal conditions, including GERD.

Conclusion

An internal burning sensation is a signal that something is amiss, but the cause isn't always obvious. While common culprits like GERD, gastritis, and ulcers are frequent offenders, nervous system responses related to anxiety can also create this unsettling feeling. The key to finding relief is to pay close attention to your symptoms, identify potential triggers, and know when to seek professional medical advice. By addressing the root cause, you can effectively manage the discomfort and restore your quality of life.

Frequently Asked Questions

The most common cause is often related to digestive issues, such as acid reflux or Gastroesophageal Reflux Disease (GERD), which occurs when stomach acid backs up into the esophagus and causes irritation.

Yes, anxiety can trigger your body's stress response, which increases nerve sensitivity. This can lead to a perceived internal burning sensation, though it's often not related to a digestive issue but rather to heightened nervous system activity.

You should see a doctor if the burning is severe, persists for more than a few days, or is accompanied by other symptoms like unexplained weight loss, difficulty swallowing, or signs of bleeding such as black or tarry stools.

Yes, certain foods and drinks can trigger or worsen the burning, especially in those with digestive sensitivities. Common culprits include spicy or fatty foods, caffeine, alcohol, and acidic items like tomatoes and citrus fruits.

For mild cases, you can try over-the-counter antacids, avoid trigger foods, eat smaller meals, and refrain from lying down immediately after eating. If the cause is stress-related, deep breathing and relaxation techniques may help.

Yes, peptic ulcers are open sores that develop on the stomach lining and are a common cause of a burning or gnawing stomach pain. This pain often worsens on an empty stomach or after certain meals.

Yes, smoking can irritate the digestive tract and is a known risk factor for developing and worsening conditions like GERD and peptic ulcers, which in turn can cause a burning sensation.
