What Causes Bloating In The Stomach
Gas
Gas is a natural byproduct of digestion, but too much intestinal gas means your digestion is gone awry. While you can ingest gasses by swallowing air or drinking carbonated beverages, these gasses mostly escape through belching before they reach your intestines. Gasses in your intestines are mostly produced by gut bacteria digesting carbohydrates, in a process called fermentation.
If theres too much fermentation going on, its because too many carbohydrates werent naturally absorbed earlier in the digestive process, before reaching those gut bacteria. That could be for several reasons. Maybe you just ate too much too fast for proper digestion. Or you might have a specific food intolerance or gastrointestinal disease. Some possible causes include:
Digestive Contents
These can include solids, liquids, and gas. Digestive contents can build up in your digestive system when there is a backup or restriction in your digestive tract or when the muscles that move digestive contents along are somehow impaired. Any build-up of digestive contents along the digestive tract will leave less room for normal amounts of gas to process through. It also leaves less room for other things in your abdomen, including circulatory fluids and fat, making everything feel tighter. Causes of build-up can include:
Hormones
Other Causes
What Naturally Relieves Bloating
Here are additional suggestions to decrease bloating: Eat slowly, and consume smaller, more frequent meals. Chew your foods well. Drink beverages at room temperature. Have your dentures checked for a good fit. Increase physical activity during the day. Sit up straight after eating. Take a stroll after eating.
Deflating Postmeal Bloat Is Simpler Than You Think
Is the holiday season bringing out your extra-indulgent side? It happens and you may end your holiday dinner feeling like your bellys bulging from all that food.
Does it seem like your stomach just tripled in size? Rest assured, thats not the case, according to Brigham and Womens Hospital. Rather, its likely just gas. It’s caused by excess air or gas in the gastrointestinal tract, says Rachel Doyle, RDN, the Chicago-based owner of RAD Nutrition who focuses on gut health. When we eat, carbohydrates are broken down, and their fiber is fermented, producing gas that expands, which can lead to bloating.
Unpleasant as it is, its generally not something to worry about. Typically, bloating is not a sign of anything serious, especially if it is only occurring after large meals, says Pam Fullenweider, RD, the founder of Fully Mediterranean in Houston.

If its chronic, however, visit your healthcare provider to rule out something more serious. If you are experiencing bloating frequently, its always a good idea to explore this further with a doctor or dietitian to determine the root cause and rule out any underlying medical conditions, Fullenweider says.
Even your run-of-the-mill bloating can be a pain, though. The good news is you dont have to just sit uncomfortably and wait it out. Follow these seven quick tips to get rid of bloating and return to the holiday merriment.

Which Foods Cause Stomach Bloating After Eating
All types of foods can be triggers for bloating, including carbohydrates, fats, and proteins. For some people, having a food intolerance can also increase the risk of bloating. The most common triggers include apples, dairy products, beans, cruciferous vegetables such as cauliflower and cabbage, lettuce, onion, peaches, and pears. Artificial sweeteners, like those found in diet sodas, can also be a cause of bloating. Many people cannot digest these sweeteners, resulting in an unusual amount of gas.
Switching to a whole grain diet has been known to cause bloating, as the amount of fiber intake is significantly increased after switching to whole grains and fiber is an indigestible carbohydrate. If you plan to switch to a whole grain diet, make sure to do so slowly and drink plenty of water.
Salt is another well-known culprit of bloating. When people talk about losing water weight, what they are referring to is the bodys natural tendency to decrease water retention when salt intake is reduced. Avoiding foods with high salt content can prevent water retention and the bloated feeling associated with it.
Dairy intolerance is the most common cause of bloating. Nearly 10 percent of adults suffer from some form of dairy intolerance. While calcium is a required nutrient for the bodys health and well-being, it can be sourced from other foods besides those containing lactose. There are also many lactose-free alternative dairy options.

You’re Eating Foods That Cause Gas
As you can guess, it’s not just how you eat that affects how you feel after a meal, but also what you eat. Common foods that can cause bloating include certain vegetables, artificial sweeteners and items with fructans, a specific type of sugar that can be hard to digest, Niket Sonpal, MD, a New York City-based, board-certified internist and gastroenterologist and faculty member with Touro College of Medicine, tells LIVESTRONG.com.
Cruciferous veggies:“We’ve all heard the song about beans being the ‘magical fruit,'” quips Hooper. “But in this case, it may be magical ‘veggies’ that are doing the trick.” She notes that bloating is common with cruciferous vegetables, including broccoli, cauliflower, kale, Brussels sprouts, cabbage and bok choy.
Artificial sweeteners:“This is something most people don’t know artificial sweeteners such as aspartame remain unchanged in the digestive system,” Hooper tells LIVESTRONG.com. “As in, they don’t break down like regular food.” That becomes a problem when your gut bacteria try to feed on them. The fact that your gut bugs can’t break them down causes gas and bloating.
High-fructose foods:“Fructose, a natural sugar added to many processed foods, is difficult for many people to digest,” Dr. Sonpal says. According to a January 2014 paper in Current Gastroenterology Reports, it’s suspected that as fructose has become more common in our diets today, more people are unable to digest the sugar properly.

Why Is My Stomach Bloated
The most common cause of stomach pain and bloating is excess intestinal gas. If you get a bloated stomach after eating, it may be a digestive issue. It might be as simple as eating too much too fast, or you could have a food intolerance or other condition that causes gas and digestive contents to build up. Your menstrual cycle is another common cause of temporary bloating. Sometimes a bloated stomach can indicate a more serious medical condition.
How Do You Treat Bloating
If you experience bloating that can’t be avoided, there are over-the-counter medications that can help ease discomfort.
- Antacidscontain simethicone, which adhere to bubbles in the stomach so that gas is more easily released.
- Lactaid contains lactase, which can help prevent gas for people with lactose intolerance.
- Pepto-Bismol, which is the brand name for bismuth subsalicylate,may help reduce bloating caused by an upset stomach.
- Beano is a product that contains an enzyme called alpha-galactosidasethat breaks down complex carbohydrates into more digestible sugars. This helps prevent gas.
- Probioticsare “good” bacteria that help maintain the health of the digestive system. They can be found in foods such as yogurt as well as in OTC supplements.
- Movement and massage,like a walk around the block or an abdominal self massage, can help get gasses in the digestive system moving.

You Have A Gastro Issue
And no matter what you eat, or how you eat, a gastrointestinal disorder such as lactose intolerance, IBS or Celiac disease can also cause bloating, or make it worse, Dr. Sonpal says.
Irritable Bowel Syndrome
IBS is an “extremely common” gut disorder affecting between 10 and 15 percent of all people in the U.S., according to The American College of Gastroenterology .
Up to 96 percent of people with IBS report bloating as their main symptom, per a September 2014 report in Gastroenterology & Hepatology. Other common symptoms, according to the ACG, include recurring abdominal discomfort or pain along with constipation, diarrhea or both.
IBS tends to be more common in women, and although there are no exact tests to diagnose IBS or exact treatment options, it can often be managed with things like diet, lowering your stress levels and certain lifestyle changes. That’s why it’s important to speak with a doctor about regular bloating or other abdominal symptoms you may be having.
Celiac Disease
The National Institute of Diabetes and Digestive and Kidney Disease lists bloating, or a feeling of fullness in the abdomen, as the first symptom for Celiac disease, which is a digestive disorder that damages the small intestine and is triggered by gluten, a protein in wheat, barley and rye.
Lactose Intolerance
Drinking Too Much Soda

Carbonated beverages, such as soda or sparkling water, are a common reason for bloating. The fizz in your favorite sodas can cause gas to get trapped in your stomach, which can lead to bloating and belching.
Try limiting the amount of soda you drink and switch to a healthier alternative. Water with cucumber or lemon can offer a flavorful drink with your meal, and black tea can provide the caffeine kick you may need in the early afternoon. If youre already feeling bloated, peppermint tea is a common remedy that can be used to help reduce the discomfort.

Be Aware Of Food Intolerance And Allergies
Bloating is a typical symptom of a food intolerance or allergy. Intolerances and allergies can cause excessive gas production or gas to become trapped in the gastrointestinal tract. The foods most likely to cause this are wheat or gluten.
No reliable tests exist to identify a specific food intolerance or allergy, so the best way to identify them is through trial and error. It can help to keep a food diary to track which foods are causing symptoms, such as bloating.
Does Drinking Water Help With Bloating
While it may seem counterintuitive, drinking water may help to reduce bloat by ridding the body of excess sodium, Fullenweider says. Another tip: Be sure to drink plenty of water before your meal too. This step offers the same bloat-minimizing effect and can also prevent overeating, according to the Mayo Clinic.
