Belching and gastric bloat are uncomfortable symptoms that many people experience and often associate with digestive issues. When these symptoms persist, patients may seek help from a gastroenterologist or internist, who might prescribe proton pump inhibitors, recommend drinking more water, or even suggest testing for conditions like SIBO (Small Intestinal Bacterial Overgrowth). While these treatments can sometimes help, they often miss the mark. In this blog, we’ll explore the common causes of belching and many forms of gastric bloat, why constipation is frequently the main culprit, and how lifestyle factors—like posture and stress—play a bigger role than you might think.
1. When Is Belching Just a Burp (and Normal), and When Is It Over the Top?
Belching is a natural bodily function that occurs when air swallowed during eating or drinking is expelled from the stomach. It’s perfectly normal to burp occasionally, especially after a meal or when drinking carbonated beverages. However, there’s a difference between the occasional burp and excessive belching that may signal a deeper issue.
- Normal Belching: A burp or two after a meal is completely normal, especially if you’ve eaten quickly, consumed fizzy drinks, or swallowed air while talking during your meal. In these cases, your body is simply releasing the excess air trapped in your stomach.
- When Belching Becomes Excessive: If you find yourself belching frequently throughout the day, especially when not associated with meals, or if the belching is accompanied by discomfort, bloating, or other digestive issues, this could be a sign of an underlying problem. Excessive belching can indicate that your digestive system isn’t functioning properly—possibly due to constipation, bacterial overgrowth, or poor motility in the digestive tract.
2. Defining Bloat: Understanding the Different Types
Bloating is a common and often uncomfortable sensation where the abdomen feels full, tight, or distended. It can be temporary and harmless, or it can signal an underlying issue. Understanding the nature of your bloating can help you pinpoint its cause and determine whether further investigation is needed.
- Gastric Bloating: This type of bloating typically occurs after eating certain foods and may be related to an immune response or food intolerance. Common triggers include dairy, gluten, or high-FODMAP foods, which can cause gas and discomfort as your body reacts to the substances.
- Hormonal Bloat: Bloating can also be linked to hormonal fluctuations, particularly in women. For example, ovarian dysfunction or hormonal changes during menstruation, pregnancy, or menopause can cause water retention and bloating.
- Chronic Bloating: If you experience bloating regularly, regardless of diet or hormonal cycles, it could be a sign of a more chronic condition such as irritable bowel syndrome (IBS), small intestinal bacterial overgrowth (SIBO), or even thyroid dysfunction.
3. The Root Causes of Belching and Bloating
While constipation is a common cause of belching and bloating, it is not the only one. There are multiple factors that can lead to these symptoms, and understanding the root cause–or causes, is essential for effective treatment.
- Constipation: When stool builds up in the digestive tract, it can slow down the entire system, causing excess gas and pressure that leads to both belching and bloating. Ensuring regular bowel movements is often the first step toward relief.
- Food Intolerances and Sensitivities: Certain foods, like dairy, gluten, or high-FODMAP foods, can trigger bloating and belching in people with sensitivities. These foods can be harder to digest, leading to gas production and discomfort.
- Bacterial Overgrowth (SIBO): Small intestinal bacterial overgrowth (SIBO) occurs when bacteria that normally reside in the large intestine move into the small intestine. This overgrowth can lead to excessive fermentation of undigested food, producing gas that causes bloating and belching.
- Hormonal Fluctuations: Hormonal changes, especially in women during menstruation, pregnancy, or menopause, can lead to water retention and bloating. These fluctuations can also slow down digestion, contributing to gas buildup.
- Histamine Intolerance: Elevated histamine levels, particularly from consuming aged or fermented foods, can cause bloating and other digestive issues. For those with histamine intolerance, starting a food diary and tracking consumption throughout the year, particularly during allergy season can be beneficial.
- Poor Eating Habits: Fast eating, mouth breathing, or stress-eating can cause you to swallow excess air, which leads to belching. Stress can also slow digestion, further contributing to bloating.
- Autoimmune Diseases: Autoimmune diseases occur when the body’s immune system mistakenly attacks its own tissues. In many autoimmune conditions, the digestive system can be directly or indirectly affected, leading to bloating, gas, and other digestive symptoms.

Autoimmune conditions, such as celiac disease, inflammatory bowel disease (IBD), and even autoimmune thyroid disorders like Hashimoto’s thyroiditis, can significantly impact digestive health and contribute to bloating.
4. Ruling Out Bacterial Overgrowth
Conditions like SIBO disrupt the migratory motor complex (MMC)—the system that cleans out the small intestine between meals, clearing bacteria and food residue. If this system is impaired, bacterial overgrowth can occur, leading to fermentation of undigested food and the production of excess gas.
- MMC and Gut Health: The MMC plays a key role in keeping bacteria levels in check. When it’s not functioning properly—often due to constipation, poor motility, or nervous system fatigue—bacterial overgrowth becomes more likely.
- Avoid Probiotics and Prebiotics for Now: Many patients, eager to avoid antibiotics, turn to probiotics or prebiotics, thinking these will help restore gut balance. However, this can be counterproductive if there’s already bacterial overgrowth present. Instead of feeding the unwanted bacteria, it’s important to first restore motility and address overgrowth.
- Watch for Histamine Levels: Fermented foods, often considered healthy for digestion, can be high in histamines, which may worsen bloating and belching for some people, especially those with histamine intolerance. Elevated histamine levels from foods –examples include cider, beer, wine, kombucha, sauerkraut, and so on, can cause gas, bloating, and other digestive discomforts. It’s important to monitor your intake of these foods closely for symptoms after consuming them.
5. Why Posture and Habits Matter More Than You Think
While digestive health is key, we often overlook simple habits and lifestyle factors that contribute to belching and bloating, such as posture and eating habits.
- Posture: Slouching or sitting in a hunched position during meals can compress the stomach and intestines, making it harder for food to pass through and increasing the chance of trapped air. Sitting upright while eating allows for better digestion and less air intake.
- Mouth Breathing: Many people unknowingly gulp down air when they breathe through their mouth while eating or talking during meals. This excess air has nowhere to go but up, causing belching. Practicing nasal breathing and eating mindfully can reduce air intake and alleviate symptoms.
- Stress-Eating: Stress-eating or eating quickly can cause you to swallow large amounts of air along with your food. When under stress, the body also diverts energy away from digestion, leading to poor breakdown of food and gas buildup. Mindful eating, with slower chewing and deep breathing, can help reduce these effects.
To prevent and manage belching and gastric bloat, consider making these simple but effective lifestyle changes that include eating slowly, adjusting your posture, and practicing nasal breathing. For a list of physician-recommended lifestyle tips, click here.
6. A Deeper Clinical Evaluation: The Functional Medicine Work-Up
In the traditional medical model, a patient presenting with symptoms like bloating, belching, and acid reflux might be referred to a gastroenterologist or internist. Typically, the approach would involve scheduling an endoscopy to rule out structural issues in the esophagus or stomach, along with possibly checking for excess hydrogen and methane gas production via a breath test. The treatment would likely include acid-blocking medications (proton pump inhibitors or H2 blockers) or antibiotics if bacterial overgrowth is suspected.
While these treatments can provide temporary relief, they often miss the underlying root causes, which can lead to recurring symptoms. In functional medicine, the approach is more comprehensive and individualized, recognizing how crucial digestion is to overall metabolism, nutrient absorption, energy production, and immune function. Here’s how we might manage bloating, belching, and acid reflux differently:
The Functional Medicine Approach to Digestive Symptoms
- Comprehensive Digestive Function Testing: Instead of relying solely on structural evaluations (like endoscopies), functional medicine looks deeper at how well your digestive system is actually working. This may involve:
- Stool Analysis: A thorough stool test can assess your gut microbiome balance, inflammation markers, and whether you’re properly digesting and absorbing nutrients. It can also reveal if there’s a lack of beneficial bacteria, or the presence of pathogens or yeast overgrowth.
- SIBO Testing: Like traditional medicine, we may check for excess hydrogen and methane gas production. However, we’ll also consider the broader context of your gut motility and digestion, and why these gases are being produced, rather than simply treating the symptoms.
- Digestive Enzyme and Bile Function: We assess whether your body is producing adequate digestive enzymes and bile acids, which are crucial for breaking down food. Without them, undigested food can ferment in the gut, leading to bloating, gas, and reflux.
- Hormonal Evaluation: Hormonal balance plays a major role in digestion. For instance, sluggish thyroid function can slow down the digestive process, contributing to constipation, bloating, and nutrient malabsorption. We also assess adrenal function and overall stress response, as elevated cortisol levels can interfere with digestion and increase gut permeability.
- Nutrient Absorption and Metabolism: Digestion is key to nutrient absorption, and nutrient deficiencies can have ripple effects throughout the body. We take a close look at how well you’re absorbing essential nutrients like B vitamins, omega-3 fatty acids, and magnesium, which all play roles in gut motility and energy production.
- Food Sensitivities and Intolerances: We explore possible food sensitivities or intolerances that may be triggering symptoms. Common culprits include gluten, dairy, and high-FODMAP foods, which can cause gas, bloating, and reflux when they aren’t digested properly.
- Bacterial Overgrowth and Histamine Intolerance: While traditional medicine may stop at diagnosing SIBO (Small Intestinal Bacterial Overgrowth), we go further by examining bacterial overgrowth throughout the entire digestive system. We also consider histamine intolerance, particularly for those consuming large amounts of fermented foods. Elevated histamine levels can cause bloating, belching, and discomfort.
- Restoring Digestive Function: Instead of simply prescribing acid-blocking medications or antibiotics, we aim to restore proper digestive function. This may involve:
- Supplementing with digestive enzymes or bile salts to aid in the breakdown of food.
- Supporting gut motility through natural motility agents like ginger or specific motility supplements.
- Targeting the root causes of bacterial overgrowth without disrupting the gut microbiome balance.
