You finish what felt like a normal meal… and suddenly your jeans feel two sizes too small. Sound familiar? Bloating isn’t just uncomfortable—it can be downright disruptive. But what’s actually going on when your belly balloons like that?
Contrary to popular belief, bloating isn’t always about eating “too much.” Sometimes it’s your gut microbiome. Other times it’s hormones, stress, or that second oat milk latte. Let’s break down the real reasons you feel bloated—and what you can actually do about it.
1. You’re Swallowing Air (Without Even Noticing)
Yep, bloating sometimes starts with your mouth. Chewing gum, drinking carbonated drinks, eating too fast, or even talking while eating can lead to excess air in your digestive tract. That air has to go somewhere—and often, it gets trapped in your stomach or intestines.
What to do: Slow down when you eat. Skip the straw. And if you love soda, try switching to flat alternatives like infused water or herbal teas. According to the National Institutes of Health (NIH), aerophagia (air swallowing) is a common but under-recognized cause of bloating.
2. Your Gut Bacteria Are Partying a Little Too Hard
Your intestines are home to trillions of bacteria—most of them helpful. But when there’s an imbalance (called dysbiosis), those microbes can ferment undigested food, producing gas as a byproduct. This is especially true with FODMAPs—a group of carbs that are poorly absorbed in the small intestine.
What to do: Consider trying a low-FODMAP diet, especially if you have IBS. Foods like onions, garlic, beans, apples, and dairy are common culprits. But don’t go low-FODMAP long term without guidance—it can negatively impact your gut diversity. Consult a dietitian first.
3. You Might Be Constipated (Even If You’re Going Daily)
Bloating and constipation go hand in hand. Even if you’re having bowel movements, you might not be fully evacuating. That stool buildup can trap gas and cause visible distension. If you ever feel “backed up” or your stomach feels hard to the touch, this might be the reason.
What to do: Increase your fiber and water intake—but do it gradually. Sudden spikes in fiber can actually worsen bloating. And don’t underestimate the power of regular movement. Even a 10-minute walk post-meal can stimulate your colon and get things moving.
4. Hormones Could Be Messing With Your Gut
Ever feel puffy right before your period? You’re not imagining it. Fluctuations in estrogen and progesterone can slow digestion and lead to water retention. Many women report increased bloating during the luteal phase of their menstrual cycle.
What to do: Track your symptoms in relation to your cycle. Magnesium-rich foods (like spinach, almonds, and bananas) may help reduce water retention. Some people find relief with natural diuretics like dandelion tea—but always check with your provider first, especially if you’re on medication.
5. Food Intolerances Are Sneakier Than You Think
Lactose and gluten get all the attention, but you could be reacting to less obvious things like eggs, soy, or even artificial sweeteners. These reactions aren’t always full-blown allergies; sometimes, it’s a delayed sensitivity that causes inflammation and gas buildup hours later.
What to do: Keep a food and symptom journal. Try a short-term elimination diet under the guidance of a healthcare provider. And remember—just because a food is “healthy” doesn’t mean it’s right for your body.
6. You’re Stressed (And Your Gut Knows It)
There’s a reason they call it a “gut feeling.” The brain and gut are deeply connected through the gut-brain axis. Chronic stress can alter gut motility, increase sensitivity, and trigger bloating—even if you haven’t eaten anything unusual.
What to do: Incorporate stress-reducing practices like meditation, breathwork, or even just unplugging from screens at night. Studies have shown that mindfulness-based stress reduction (MBSR) can significantly reduce bloating in people with IBS (NIH).
7. Underlying Medical Conditions Might Be at Play
Sometimes, bloating isn’t just bloating. It can be a red flag. Conditions like small intestinal bacterial overgrowth (SIBO), celiac disease, endometriosis, and even ovarian cancer can cause chronic or severe bloating.
What to do: If your bloating is persistent, painful, or accompanied by other symptoms like weight loss, fatigue, or irregular bowel habits, see a doctor. A breath test can help diagnose SIBO. Blood tests or imaging may be needed to rule out more serious causes.
So… Why Do You Feel Bloated?
The truth is, bloating isn’t one-size-fits-all. Sometimes it’s your dinner. Other times, it’s your hormones, your habits, or your headspace. What matters is tuning into your body’s signals—not just pushing through the discomfort with stretchy pants and denial.
Want to figure out your personal bloat triggers? Start small. Keep a symptom log. Be kind to your gut. And don’t be afraid to ask for help. Your body is talking. Are you listening?
