That uncomfortable heat radiating from your stomach can be alarming and puzzling. You’re not alone if you’ve ever wondered, “Why Does My Stomach Feel Hot Inside?” This burning sensation is a common complaint with a range of potential causes, most of which are not serious. However, understanding these causes can help you find relief and know when to seek medical advice.
This article delves into the common reasons behind that hot feeling in your stomach, exploring everything from everyday indigestion to less frequent but important conditions. We’ll cover associated symptoms, treatment options, and crucial guidance on when it’s time to consult a healthcare professional.
Common Culprits Behind the Burning Feeling
Let’s explore five of the most frequent reasons why you might be experiencing a hot sensation in your stomach:
1. Indigestion (Dyspepsia): The Usual Suspect
Indigestion, also medically known as dyspepsia, is a very common condition characterized by a group of symptoms occurring together in the gut, and a burning stomach is a hallmark sign.
It’s estimated that around 25% of adults in the United States experience indigestion each year. Many describe this as a burning feeling specifically in the upper abdomen.
Several lifestyle and dietary factors can trigger indigestion, including:
- Dietary Indiscretions: Overindulging in alcohol, coffee, or carbonated beverages; eating too quickly; or consuming highly acidic, spicy, or fatty foods.
- Stress: Emotional and physical stress can significantly impact digestion.
- Smoking: Nicotine can irritate the digestive system.
- Medications: Certain medications, such as some antibiotics and nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, are known to cause indigestion.
Furthermore, indigestion can be a symptom of underlying health conditions:
- Acid Reflux (GERD): This occurs when stomach acid flows back up into the esophagus, the tube connecting your mouth and stomach. This backflow can cause a burning sensation often felt behind the breastbone, commonly known as heartburn.
- Functional Dyspepsia: This refers to chronic indigestion where no specific underlying cause can be identified. Individuals with functional dyspepsia may experience a burning sensation in the stomach area, typically just below the rib cage.
Accompanying Symptoms of Indigestion
Beyond the burning sensation, indigestion can manifest with other uncomfortable symptoms such as:
- Early Satiety: Feeling full very quickly during a meal or uncomfortably full after eating.
- Bloating and Gas: Increased abdominal distension and flatulence.
- Frequent Burping: Burping that may bring up food or stomach fluids.
- Stomach Noises: Gurgling or growling sounds from the abdomen.
Managing Indigestion
Fortunately, most cases of indigestion can be managed effectively with lifestyle adjustments, dietary modifications, and over-the-counter medications.
Dietary changes that can alleviate symptoms include reducing or avoiding:
- Alcoholic Beverages
- Carbonated Drinks
- Caffeinated Drinks
- Highly Acidic Foods (e.g., tomatoes, citrus fruits)
- Spicy Foods
- Fatty and Greasy Foods
Over-the-counter antacids, such as sodium bicarbonate or esomeprazole, can neutralize stomach acid and provide relief from the burning sensation.
However, if indigestion symptoms persist for more than two weeks, it’s important to consult a doctor to rule out any underlying medical conditions.
2. Food Intolerances: When Food Turns Against You
Food intolerances can also trigger a burning feeling in the stomach, along with other symptoms that mimic indigestion [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6423694/]. Unlike food allergies, food intolerances don’t involve the immune system but rather the digestive system’s difficulty in processing certain foods.
Common food intolerances include:
- Lactose Intolerance: Difficulty digesting lactose, a sugar found in dairy products.
- Gluten Intolerance (Non-Celiac Gluten Sensitivity): Sensitivity to gluten, a protein found in wheat, barley, and rye.
- FODMAP Intolerance: Intolerance to certain types of carbohydrates (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols).
Even without a specific intolerance, some foods and drinks can irritate the gut lining and cause symptoms. Spicy foods and alcohol are prime examples of substances that can lead to gut irritation.
Additional Symptoms of Food Intolerance
Besides a burning stomach, food intolerances can manifest with a variety of symptoms, including [https://www.nhs.uk/conditions/food-intolerance/]:
- Bloating
- Gas
- Diarrhea
Adverse reactions to food intolerances can also extend beyond digestive issues and present as:
- Headaches
- Fatigue and Low Energy
- Nausea and Vomiting
- Constipation
- Joint Pain
- Skin Rashes
Managing Food Intolerances
The primary approach to managing food intolerances is identifying and avoiding the culprit food or drink. An elimination diet, guided by a dietician, can be helpful in pinpointing triggers.
While complete avoidance may be necessary initially, a dietician can often help you find ways to reintroduce small amounts of the triggering food back into your diet over time, as tolerance can sometimes be built.
To gain a deeper understanding of food intolerances and allergies, resources like the ZOE Science & Nutrition podcast offer valuable insights.
3. Peptic Ulcers: Sores in the Stomach Lining
Peptic ulcers are sores that develop in the lining of the stomach or the upper part of the small intestine (duodenum). A common cause of peptic ulcers is infection with Helicobacter pylori (H. pylori) bacteria [https://www.niddk.nih.gov/health-information/digestive-diseases/peptic-ulcers-stomach-ulcers/symptoms-causes].
A burning sensation in the stomach is the most frequently reported symptom of a peptic ulcer.
The pain associated with peptic ulcers can occur anywhere between the belly button and the breastbone and is often more pronounced on an empty stomach.
Other factors besides H. pylori infection can contribute to peptic ulcers, including long-term use of NSAIDs and certain medical procedures involving the stomach or small intestine. Interestingly, men have been found to have a higher risk of developing peptic ulcers compared to women.
Associated Symptoms of Peptic Ulcers
In addition to the characteristic burning stomach pain, peptic ulcers can also cause:
- Bloating
- Belching
- Feeling Full Quickly
- Acid Reflux
- Nausea
If an H. pylori infection is the underlying cause of the ulcers, individuals may also experience a decreased appetite and unintentional weight loss. It’s important to note that peptic ulcers don’t always present with noticeable symptoms.
Treatment for Peptic Ulcers
Treatment for peptic ulcers depends on the cause. If H. pylori infection is identified, a doctor will typically prescribe antibiotics to eradicate the bacteria. Proton pump inhibitors (PPIs) may be prescribed to reduce stomach acid production, particularly if NSAID use is a contributing factor.
Peptic ulcers can take several months to heal completely with appropriate medical management.
4. Medication Side Effects: NSAIDs and Stomach Burning
Nonsteroidal anti-inflammatory drugs (NSAIDs), commonly used to relieve pain and reduce inflammation, are known to cause indigestion and peptic ulcers, both of which can manifest as a burning sensation in the stomach.
People commonly take NSAIDs to manage conditions like joint pain, headaches, and premenstrual symptoms. These medications are also used to alleviate symptoms associated with viral infections like colds, flu, and COVID-19.
Commonly used NSAIDs include ibuprofen, naproxen, diclofenac, and aspirin.
Other Potential Side Effects of NSAIDs
Besides stomach issues, NSAID use can lead to other side effects, such as:
- Headaches
- Dizziness
- Drowsiness
In rarer cases, more severe reactions can occur, including:
- Allergic Reactions
- Liver, Heart, Kidney, or Circulation Problems
- Strokes
Minimizing and Managing NSAID Side Effects
If you are taking NSAIDs and develop a burning sensation in your stomach, it’s crucial to discuss alternative pain management strategies with your doctor.
Taking NSAIDs with food and plenty of water may help reduce the risk of developing side effects.
5. Irritable Bowel Syndrome (IBS): A Chronic Digestive Condition
Irritable bowel syndrome (IBS) is a long-term condition affecting the digestive system, characterized by a wide array of symptoms.
While abdominal pain in IBS is often described as stabbing, aching, sharp, or throbbing, it can also be experienced as a burning sensation, as pain perception varies significantly from person to person.
IBS is a prevalent condition, affecting approximately 5-10% of the global population.
The International Foundation for Gastrointestinal Disorders reports that abdominal pain is the primary reason why most individuals with IBS seek medical attention.
Research studies indicate that women are twice as likely as men to develop IBS in the United States. These studies also suggest that women with IBS may experience a worsening of symptoms, including abdominal pain, during menstruation.
Accompanying Symptoms of IBS
IBS is characterized by significant changes in bowel habits, which can manifest as constipation, diarrhea, or alternating between both.
Other common symptoms of IBS include:
- Acid Reflux
- Bloating and Abdominal Swelling
- Excessive Gas
- Low Energy Levels
- Nausea
Managing IBS Symptoms
Diagnosing IBS can be challenging as there is no single diagnostic test. Doctors typically rule out other conditions, such as celiac disease and inflammatory bowel disease, before considering an IBS diagnosis.
Managing IBS symptoms often involves identifying and modifying dietary triggers [https://www.nhsinform.scot/illnesses-and-conditions/stomach-liver-and-gastrointestinal-tract/irritable-bowel-syndrome-ibs/managing-irritable-bowel-syndrome-ibs]. These triggers can include certain sweeteners or processed foods containing resistant starch.
The low-FODMAP diet is a commonly recommended approach for managing IBS. This diet restricts certain types of carbohydrates and sugars that are poorly absorbed in the small intestine.
Dr. Will Bulsiewicz, ZOE’s U.S. Medical Director and a board-certified gastroenterologist, suggests that simple dietary modifications can provide rapid symptom relief for some IBS patients: “Cut out caffeine, alcohol, and spicy and fatty foods.”
He also mentions that peppermint oil, probiotics, and fiber supplements can be helpful, but finding the right approach often involves some experimentation. A dietitian can guide individuals in adjusting fiber intake to manage constipation and diarrhea effectively.

Could Stomach Cancer Be the Cause?
While less common, stomach cancer can also cause a burning sensation in the abdomen, particularly in later stages when symptoms become more apparent. However, it’s crucial to remember that a burning stomach is far more likely to be due to more common conditions like indigestion, infection, or ulcers.
Stomach cancer is relatively rare, accounting for approximately 1.5% of new cancer diagnoses in the U.S. Moreover, the incidence of stomach cancer is declining by about 1.5% annually. The American Cancer Society estimates around 26,500 new cases will be diagnosed in the United States in 2023.
Key Takeaways: Common Causes of Stomach Burning
In summary, several factors can lead to a burning sensation in your stomach. The most frequent causes include:
- Indigestion
- Food Intolerances
- Peptic Ulcers
- Certain Medications
- Irritable Bowel Syndrome (IBS)
Although stomach cancer is a possibility, it is significantly less likely than the other causes listed above.
When to Seek Medical Attention
While a burning sensation in your stomach is often benign, certain accompanying symptoms warrant prompt medical evaluation. Seek medical help if you experience any of the following along with stomach burning:
- Frequent Vomiting
- Vomiting Blood
- Black or Tarry Stools
- Blood in Stools
- Dizziness or Fainting
- Loss of Appetite
- Unexplained Weight Loss
- Sudden, Severe Abdominal Pain that Doesn’t Subside
- Difficulty Swallowing or Painful Swallowing
- Pain in Arm, Chest, Jaw, or Neck
- Shortness of Breath
- Yellowing of Skin or Eyes (Jaundice)
Additionally, if the burning sensation persists for more than 2 weeks, it’s advisable to consult a doctor.
Diagnosis: Unraveling the Cause
To determine the underlying cause of your burning stomach, your doctor will gather information about your symptoms and medical history [https://gi.org/topics/abdominal-pain/]. Keeping track of the following details can be helpful:
- Location of the Pain
- Frequency of the Burning Sensation
- Timing of Symptoms and Pattern (e.g., after meals, at night)
- Whether the Pain Radiates to Other Areas
- Any Accompanying Symptoms (e.g., vomiting, nausea, diarrhea, constipation)
Your doctor will perform a physical examination to check for tenderness, swelling, and assess bowel sounds. If the cause remains unclear, further diagnostic tests may be ordered, including:
- Blood, Urine, and Stool Tests
- Imaging Tests (X-rays, MRI, CT Scans)
- Endoscopy (insertion of a thin, flexible tube with a camera into the stomach)
Diet and Lifestyle Strategies for Prevention
Dr. Bulsiewicz emphasizes the importance of dietary changes in managing acid reflux [https://joinzoe.com/learn/heartburn-causes-and-what-to-do], and these principles extend to general digestive health and preventing stomach burning. It’s not just what you eat, but how you eat that matters.
Dr. Bulsiewicz’s recommendations include:
- Mindful Eating: Eating slowly and in a relaxed environment, savoring your food.
- Avoid Post-Meal Reclining: Refrain from bending over or lying down immediately after eating.
- Time for Digestion: Allow 3-4 hours for digestion before going to bed.
- Gradual Fiber Increase: Gradually increase fiber intake in your diet.
He also advocates for the Mediterranean diet, which prioritizes:
- Fruits, Vegetables, and High-Fiber Whole Grains
- Legumes, Seeds, and Nuts
- Olive Oil as Primary Fat Source
- Limited Lean White Meat, Fish, Dairy, and Eggs
For managing IBS, Dr. Bulsiewicz highlights the crucial role of the gut microbiome [https://joinzoe.com/learn/podcast-conquer-ibs]:
“If you have irritable bowel syndrome — or frankly, even if you don’t — we should all be orienting our diet and lifestyle toward supporting the gut microbiome, because ultimately the gut microbiome plays a central role in the development of IBS.”
