What can make your stomach feel bloated and gassy?

Have you ever experienced a feeling of fullness or tightness in your abdomen, accompanied by burping or passing gas? If so, you may have suffered from bloating and gas, which are common digestive system-related problems that affect many people. But what causes these uncomfortable symptoms and how can you prevent them? In this blog post, we will explore some of the possible reasons and remedies for gas, stomach pain, and bloating.

What is bloating and gas?

Bloating is a sensation of swelling or enlargement in the abdomen, which may make you feel like you have eaten too much or have a lot of air trapped in your stomach. Gas is the result of air or other gases moving through your digestive tract, which may cause you to burp or fart. Both bloating and gas can be caused by various factors, such as the food you eat, the way you eat, or the bacteria in your intestines.

What are some common causes of bloating and gas?

Some of the most common causes of bloating and gas include:

  • Food intolerance: Some people may have difficulty digesting certain foods, such as dairy products, gluten, or fructose, which can cause gas and bloating. This is different from a food allergy, which is a more serious immune reaction to a food. Food intolerance can be diagnosed by a doctor or by eliminating the suspected foods from your diet and observing the effects.
  • Lactose intolerance: This is a specific type of food intolerance that affects people who cannot digest lactose, which is the sugar found in milk and other dairy products. Lactose intolerance can cause gas, bloating, diarrhea, and stomach pain after consuming dairy products. Lactose intolerance can be managed by avoiding or limiting dairy products, taking lactase enzyme supplements, or choosing lactose-free alternatives.
  • FODMAP diet: FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, which are a group of carbohydrates that are poorly absorbed in the small intestine and can cause gas and bloating in some people. FODMAPs include fructose, lactose, fructans, galactans, and polyols, which are found in various foods, such as fruits, vegetables, grains, legumes, dairy products, and sweeteners. A low-FODMAP diet can help reduce gas and bloating in people with irritable bowel syndrome (IBS) or other digestive disorders. Nowadays, low-FODMAP supplements also available in the market.
  • Small intestinal bacterial overgrowth (SIBO): This is a condition where there is an excessive growth of bacteria in the small intestine, which can interfere with the normal digestion and absorption of nutrients. SIBO can cause gas, bloating, diarrhea, weight loss, and malnutrition. SIBO can be diagnosed by a breath test or a stool test and can be treated with antibiotics or probiotics.
  • Crohn's disease: This is a type of inflammatory bowel disease (IBD) that causes inflammation and ulcers in the lining of the digestive tract, which can affect any part of the tract from the mouth to the anus. Crohn's disease can cause gas, bloating, diarrhea, weight loss, abdominal pain, and bleeding. Crohn's disease can be diagnosed by a colonoscopy or a biopsy and can be treated with medication, surgery, or dietary changes.
  • Carbonated beverages: These are drinks that contain carbon dioxide gas, such as soda, sparkling water, or beer, which can cause gas and bloating when you swallow them. Carbonated beverages can also make you feel full and reduce your appetite. To prevent bloating and gas from carbonated beverages, you can limit your intake, drink slowly, or choose flat or still drinks instead.
  • Chewing gum: This is a habit that many people enjoy, but it can also cause gas and bloating. When you chew gum, you swallow air, which can accumulate in your stomach and cause bloating. Chewing gum can also stimulate your saliva production and your digestive juices, which can make you feel hungry and eat more. To prevent bloating and gas from chewing gum, you can avoid or reduce your gum chewing, choose sugar-free gum, or chew on something else, such as a mint or a carrot.

How can you prevent bloating and gas?

Besides avoiding or limiting the foods and drinks that can cause bloating and gas, there are some other tips that can help you prevent these symptoms, such as:

  • Eat slowly and chew well: This can help you reduce the amount of air that you swallow and improve your digestion. Eating slowly can also help you feel more satisfied and prevent overeating.
  • Drink plenty of water: This can help you stay hydrated and flush out any excess gas or waste from your body. Water can also help you digest your food and prevent constipation, which can cause bloating and gas.
  • Exercise regularly: This can help you improve your blood circulation and your bowel movements, which can reduce gas and bloating. Exercise can also help you relieve stress and improve your mood, which can affect your digestion.
  • Take probiotics: These are beneficial bacteria that can help you balance your gut flora and improve your digestion. Probiotics can be found in foods, such as yogurt, kefir, sauerkraut, or kimchi, or in supplements, such as capsules or powders. Probiotics can help you reduce gas and bloating, especially if you have SIBO, IBS, or other digestive disorders.
  • Consult your doctor: If you have persistent or severe gas and bloating, or if you have other symptoms, such as nausea, vomiting, fever, or blood in your stool, you should see your doctor for a proper diagnosis and treatment. Your doctor may prescribe you medication, refer you to a specialist, or recommend you a specific diet or lifestyle change.


Bloating and gas are common digestive problems that can affect anyone, but they can also be prevented or treated by following some simple tips. By knowing the possible causes and remedies for bloating and gas, you can improve your digestive health and your quality of life. Remember to eat well, drink water, exercise, take probiotics, and consult your doctor if needed. Stay healthy and happy!
