How To Get Rid of Bloating and Reduce Gas


Why am I so gassy? What causes bloating? If you’ve asked these questions you’re not alone.brunette woman with abdominal pain lying on couch

Abdominal bloating is one of the most common gastrointestinal complaints that I see as a Digestive Health Dietitian. You know, that feeling of abdominal fullness or tightness that is with you a various parts of the day (or all day long!).

It’s uncomfortable and it can sometimes be painful. It can hamper your appetite or your enjoyment of activities. It can make your clothes feel tight and sometimes, it’s visible enough for others to take notice. In other words, it’s not a whole lot of fun.

There are a number of reasons why you could be bloated and it can differ vastly from person to person. As such, there’s a number of different strategies that could work to decrease that pesky bloating or eliminate it altogether (wouldn’t that be nice?). The following are just a few of the reasons you could be bloated and some insight on foods that cause bloating:


Your eating pattern promotes bloating


Erratic eating patterns can cause your gastrointestinal bloating. Maybe you skip meals or leave long gaps between eating and overall, you just don’t have a consistent pattern to your eating habits. The main issue here is that those long gaps and irregular meals leads to overeating that can contribute to bloating. With this erratic type of eating patterns you are more likely to arrive at the table over-hungry, which predisposes you to gulping down your meal, which again leads to more bloating.

The solution: Eat regularly and don’t arrive meals over hungry. A good place to start is trying to eat every 3-5 hours. Prioritize yourself and your nutrition. Don’t let a packed schedule cause you to miss meals.


You swallow too much air


Sometimes it’s not the what you are eating but the how you are eating that contributes to your bloating. Swallowing air, whether from using straws to drink, slurping hot drinks, drinking carbonated beverages, chewing gum or eating rapidly, is an often overlooked cause of bloating. These habits cause us to ingest more air and if you’re not burping the excess air out, it only has one way to go…down. This excess air will cause you to feel bloated.

The solution: Assess whether how you are eating is contributing to your bloating. If so, eliminate drinking through straws, having carbonated beverages, chewing gum and/or slow down a bit while eating.


You’re constipated


Sometimes bloating can be a result of trapped gas and what is trapping this gas is a constipated bowel. It’s normal (and also healthy!) to produce gas. Having gas is a sign that the microbes in your gut are being fed and that’s a good thing. What happens if you are constipated though, is that that gas gets trapped and has nowhere to go. This is when you are going to really feel that trapped gas.

The solution: If this is you, you need to address the constipation. That could mean you need more fluid, more dietary fiber, or to get up and move more. It could also mean assessing the use of any constipating nutritional supplements (do you really need them?) or whether or not your bathroom routine is conducive to having regular bowel movements. If you are completely unsure why you are constipated, book an appointment with a Registered Dietitian that specializes in digestive health to help you get your bowels back on track (for more information on our services visit: Personal Nutrition Counseling: Digestive Health)


You are eating too many gas producing foods


Many healthy foods including vegetables, whole grains and legumes contain elements, such as fiber or FODMAPs, that contribute to gas and bloating. This isn’t to say that you shouldn’t eat these foods because they are associated with good health but it could be the overall amount or specific type of these foods in your diet is causing more bloating. If you have recently transitioned from a low fiber diet to a high fiber diet, or you’ve started eating more “plant-based”, you may experience more bloating. Often this bloating is temporary, as your body needs some time to adjust to this new dietary regime.

The solution: If you’ve made a recent dietary change that involves eating more legumes, vegetables and whole grains, it could be helpful to scale back on the portion sizes a bit until you’ve given your body time to adjust the new foods. Once you feel better with these portions of new foods, you can increase your portions. When it comes to dietary fiber, increasing slowly is your best bet, especially if you’ve got a more sensitive gut.

If your diet contains a lot of raw and harder to digest veggies, try having more cooked vegetables or “baby” leaf lettuce as they are easier to digest for some people. You can also try cutting down on some of the gas forming veggies like broccoli, cauliflower, kale and Brussel’s sprouts – you can still have them but just in smaller portions and alternate with vegetables that aren’t known for being gas producing.

If eating beans and legumes is new to you, try incorporating them slowly into your diet. If you are using canned beans, make sure to rinse the beans before using them as this gets rid of some of the gas promoting elements. If you are cooking dried beans, pre-soak the beans before cooking, changing up the water several times to help reduce those same gas producing particles.

If you’ve been diagnosed with Irritable Bowel Syndrome (IBS), you may be hypersensitive to FODMAPs (a type of fermentable carbohydrate) which cause bloating, among other digestive issues. If this is you, talk to an experienced Registered Dietitian to see if the low FODMAP diet is right for you.


Too many high-fat foods brunette woman with abdominal pain lying on couch


Eating lots of rich and high-fat foods can contribute to bloating in some individuals. High-fat meals can slow down digestion which can contribute to that overall bloated feeling. Another aspect of this slowed down digestion is that it can give the microbes in your gut more time to ferment food items in your gut. While we want these gut microbes to ferment some food particles (this is their food and keeps them healthy!), this slower digestion gives them more time to make bloat inducing gas.

The solution: If you think that high-fat meals may be contributing to your bloating, try choosing some lower fat or less rich meals for a time period. This doesn’t mean completely avoid fat but just being mindful of consuming larger, richer meals for a short time to see if this factor triggers your bloating.


Too many sugar-free foods


Sugar-free foods, particularly those sweetened with sugar alcohols like xylitol, sorbitol, and mannitol, can cause gas and bloating in some individuals. These sweeteners can be found in a number of products including gum, diet beverages, and sugar-free candies or desserts.

The solution: Avoid or limit food items with added sugar alcohols. Check food labels that have “sugar-free” or “no sugar added” to make sure they don’t contain these sweeteners.

If you are like a number of people, you may be taking dietary supplements. Sometimes it is the very supplements that are being taken to improve our health (or with the hopes to improve our health) that are causing the bloating and gassy symptoms. Some supplements contain ingredients that trigger bloating such as oligosaccharides, lactose or sugar alcohols. Other times, it’s the amount of supplements taken that negatively affects your digestive system and can cause you to feel bloated.

The solution: If you think that your supplements may be contributing to your bloating, it’s time to assess whether you really need to take these supplements. Are any of them essential? Is there good evidence that they work for their intended purpose? If your supplements aren’t essential (i.e. not recommended by a reputable health professional), perhaps take a short break from them to see if your bloating is reduced.

If after reading though this list, you are still having a hard time identifying the source of your bloating and gassy symptoms, it may be wise to visit a Registered Dietitian specializing in digestive health.

“I have come to think of the program as a one stop shopping excursion for everything one needs to know about creating a joyous relationship with food and our bodies. In a single word, the course has gifted me with freedom from the punishing rigidity of disordered eating, old stories that never were true, and body dysmorphia that did nothing but make me lose sight of a body that has done everything I've asked, despite my careless dismissal of her needs. Now when I look in the mirror I find myself shifting from harsh criticism to gentle gratitude.”
Lynn Haley, Pursuit of Healthiness Online Course Participant
“I spent 3 hours when first diagnosed with type 2 diabetes. I learned more from my Dietitian about food in those 3 hours than I had learned in all the years of my life. I also love the newsletter, there is always something to learn.”
Peter Whitehead, Nutrition Counseling Client
“I didn’t realize how strong my “diet mentality” was, and all the rules I had in my head about food. I was in a cycle of reward/punish/binge/cringe. I booked with your business very reluctantly, on the repeated advice of my doctor, to get my slowly rising cholesterol levels in check. I thought I knew everything about food, and my behaviour with food, but I was definitely re-schooled. My weight is creeping down, I feel good about my diet, exercise, body image, and lifestyle.”
Amy Floyd, Nutrition Counseling Client
“Thanks Andrea for an amazing presentation, I have heard all positive remarks from attendees and the evaluations show the same sentiment. It is really gratifying when a speaker does their “homework” and weaves in our profession’s day to day challenges within their content, you did an awesome job of this! You truly took the “die” out of Dietician! Your information on healthy eating and simplifying how we can work towards this as we are all so busy really hit the mark. Andrea connects very well with her audience; she is energetic, funny, and very approachable.”

I am a family physician who sees patients with a myriad of eating concerns – from wanting to know how to plan healthy meals for active families, to weight loss, to eating disorders, and so on. I cannot recommend the Health Stand team highly enough. I have worked with (and been to!) other Dieticians in the past and too often find that they just ask for food logs and make suggestions that are easily obtained online or in books. The Dieticians at Health Stand offer much more than just telling clients what they “should be eating.” In contrast, the team really does more of a counselling practice, and they work hard to help their clients learn more about why their eating habits may be off track and not optimal for them, as well as helping people to effect change at a deep level that, most importantly, is sustainable for lifetime health.”

“I am a busy mom, with kids in high level sports, working full-time downtown, and running our home acreage outside the City. I now have the knowledge and tools I need to plan for and manage the chaos of meal planning.”
Gillian Gray, Pursuit of Healthiness Online Course Participant
“As a construction company, we select speakers who can relate to our industry and its employees. Andrea’s message was delivered with humor and empathy. She makes people feel as though they can make changes without leaving behind every favorite food. Andrea focused her presentation on healthy eating as a way to keep energy high throughout the day. This message and the way it was delivered resonated with our predominantly male, blue collar culture. I would highly recommend Andrea as a speaker for groups such as ours. She will get your message across without alienating anyone in your audience – which is a huge hurdle when trying to introduce a wellness program in the workplace!”

I found my Dietitian warm, funny, and skilled at teaching nutrition concepts without the overwhelm. The general approach of each session was to mix science with emotion, which was exceedingly effective in helping me shift my perspective on food from one of anxiety to one of joy and curiosity.”
Erin Kronstedt, Nutrition Counseling Client
“Excellent presentation! What a refreshing change to have a speaker inspire rather than “lecture” about nutrition. Your captivating stories, tips and overall approach to healthy eating uplifts and puts people at ease. It was great to hear we don’t need to strive to be perfect eaters, and that small changes really can make a difference in how we feel and in our health. Thanks to Andrea, we have solutions to our everyday nutrition challenges that can actually work in real life!”
