Why Am I Always Bloated?

Persistent bloating is one of the most common symptoms women bring to me, and one of the most consistently dismissed. If you feel bloated regardless of what you eat, regardless of how carefully you've tried to manage it, this post is for you.

Not sure where your symptoms are coming from? The free Hormone Health Checklist is a good place to start.

What bloating actually is

Bloating is a feeling of fullness, tightness, or distension in the abdomen. Sometimes it's visible. Sometimes it's just uncomfortable. Often it builds across the day, starting relatively normal in the morning and worsening by the evening regardless of what you've eaten.

It's not the same as being full after a meal. And it's not something you simply have to accept as part of being a woman, even though that's what a lot of women are told.

Bloating is a signal. Your body is communicating that something in your digestive system needs attention. The question worth asking isn't how to reduce the bloating. It's what's causing it.

Why you might be bloated all the time

There isn't one single cause of chronic bloating. For most women it's a combination of factors, often working together in ways that make it hard to identify a single trigger. Here are the most common underlying drivers.

An imbalanced gut microbiome. Your gut is home to trillions of microorganisms that play a direct role in digestion, hormone regulation, immune function, and mood. When the balance of bacteria in your gut is disrupted, a condition called dysbiosis, fermentation of food in the wrong place at the wrong time produces excess gas. That gas causes bloating.

Dysbiosis is extraordinarily common. Antibiotics, a diet low in fibre and diversity, chronic stress, hormonal contraceptives, and poor sleep all affect the gut microbiome. If you've had several courses of antibiotics in your life, or if your diet has been relatively narrow for a long period, dysbiosis is worth considering.

Small intestinal bacterial overgrowth.SIBO occurs when bacteria that normally live in the large intestine migrate to the small intestine. There they ferment carbohydrates that wouldn't normally be fermented there, producing hydrogen or methane gas. The result is bloating, often within an hour or two of eating, alongside discomfort, altered bowel habits, and sometimes significant fatigue.

SIBO is underdiagnosed and frequently missed. It's one of the most common drivers of bloating that persists despite dietary changes and is worth investigating if your bloating is consistent regardless of what you eat.

Low stomach acid. Your stomach produces acid to break down food and kill pathogens before they reach the small intestine. When stomach acid is low, food isn't broken down adequately before moving through your digestive system. Undigested food particles ferment further down the gut, producing gas and bloating.

Low stomach acid is more common than people realise, particularly in women who are under chronic stress, which suppresses stomach acid production, and in women who have used proton pump inhibitors or antacids for extended periods.

Food intolerances and sensitivities. Reactions to specific foods, most commonly gluten, dairy, eggs, or high-FODMAP foods, can cause significant bloating. It's worth noting that food intolerances are often a symptom of underlying gut dysfunction rather than a permanent inability to tolerate those foods. Addressing the root cause can reduce or resolve sensitivities over time in many cases.

This is why elimination diets often provide temporary relief but not lasting resolution. Removing the food reduces the symptom. It doesn't fix what's driving the sensitivity in the first place.

Slow gut motility. How long it takes food to move through your system varies a lot between women. When transit is slow, food sits in the gut for longer, fermenting and producing gas. Slow motility is associated with constipation, hormonal imbalance, low thyroid function, dehydration, and insufficient dietary fibre.

Constipation and bloating frequently go together for exactly this reason. If your bowel movements are infrequent or incomplete, addressing motility is part of addressing bloating.

Hormonal fluctuations across your cycle. Many women notice that bloating worsens at specific points in their cycle, particularly in the days before their period. The bloating and hormones connection is something most gut-focused approaches miss entirely, and it's one of the reasons women keep getting incomplete answers.

Progesterone has a relaxant effect on smooth muscle, including the muscle in your gut wall. In the luteal phase, as progesterone rises, gut motility slows. Food moves through more slowly, fermentation increases, and bloating worsens. When progesterone drops sharply before your period, prostaglandins are released that can cause further digestive disruption.

If your bloating follows a cyclical pattern, this is your body telling you something specific about the relationship between your hormones and your gut. It is not a coincidence.

The gut-hormone connection

This is the part that changes everything for a lot of women.

Your gut and your hormones are not separate systems. They are in constant communication, and what happens in one directly affects the other.

The estrobolome, the collection of gut bacteria responsible for metabolising oestrogen, determines how much oestrogen circulates in your body at any given time. When the gut microbiome is healthy and diverse, oestrogen is processed efficiently and eliminated. When it's imbalanced, an enzyme called beta-glucuronidase becomes overactive and allows oestrogen to be reabsorbed into the bloodstream rather than excreted.

The result is elevated circulating oestrogen, which can contribute to heavier periods, worsening PMS, breast tenderness, and more bloating.

This is why addressing gut health in isolation, without considering what's happening hormonally, often produces limited results. And why addressing hormones without considering the gut misses a significant piece of the picture.

What doesn't work

A quick word on the things most women try before they get to the root cause.

Cutting out gluten and dairy can reduce bloating temporarily if you have a genuine sensitivity to those foods. But if the underlying cause is dysbiosis, SIBO, or low stomach acid, cutting gluten and dairy is unlikely to resolve it. You'll feel slightly better for a while, reintroduce something, bloat again, and conclude that you just have to live without those foods forever. That's not a solution. That's restriction without resolution.

Probiotics can be helpful but they're not a universal fix. The wrong probiotic strains in the wrong situation, particularly in the presence of SIBO, can actually worsen symptoms. Targeted supplementation based on your specific picture is very different from buying a probiotic from a health food shop and hoping for the best.

Antacids address low stomach acid symptoms by suppressing acid further, which is the opposite of what most women with bloating actually need.

None of this is said to make you feel bad about what you've already tried. These are the tools most women have access to without professional guidance. They're not the same as actually finding the cause.

What actually helps

Increase dietary fibre and diversity. Aiming for 30 different plant foods a week, vegetables, fruits, legumes, wholegrains, nuts, seeds, is one of the most practical things you can do for your gut microbiome. You don't need to overhaul everything at once. Adding two or three new plant foods each week makes a real difference over time.

Address stress. Chronic stress directly reduces stomach acid production, slows gut motility, increases intestinal permeability, and alters gut microbiome composition. You cannot consistently eat well and supplement thoughtfully and expect your gut to function optimally if your nervous system is in chronic overdrive. Stress management is not a soft add-on to gut health. It is part of gut health.

Support bowel regularity. If you're not having at least one complete bowel movement per day, transit time is likely contributing to your bloating. Hydration, dietary fibre, movement, and magnesium are the practical starting points. If constipation is a consistent pattern, it's worth investigating thyroid function and hormonal factors as potential underlying drivers.

Consider working with a practitioner. Chronic bloating that hasn't resolved with dietary changes is worth investigating properly. Identifying whether SIBO, dysbiosis, low stomach acid, or food intolerances are driving your symptoms requires a different approach for each, and getting that wrong wastes a significant amount of time and money.

The bottom line

If you're always bloated, something is driving it. It's not just the food you ate last night, it's not stress in the vague sense, and it's not something you have to accept. Your gut is telling you something specific, and that something can be identified and addressed.
