What is gut health and why does it matter?

Gut health refers to the balance and function of your digestive system, including the trillions of bacteria in your microbiome. A healthy gut influences your immune system, mood, energy, hormones, skin, and sleep. The good news is the gut is highly responsive to nutrition and lifestyle changes.

Some bloating after meals is normal, but significant daily bloating or persistent discomfort is your gut signalling that something needs attention. Common causes include dysbiosis, food intolerances, slow gut motility, stress, and hormonal changes. Identifying the underlying cause, rather than eliminating foods, is what leads to lasting improvement.

What are the signs of an unhealthy gut?

Common signs include frequent bloating, constipation or diarrhoea, abdominal pain, fatigue after eating, brain fog, poor sleep, skin issues, and getting sick often. Less obvious signs include sugar cravings, mood changes, and worsening food sensitivities. An unhealthy gut can show up in ways that do not immediately seem digestive at all.

How long does it take to improve gut health?

Many people notice meaningful changes within 4-6 weeks of consistent dietary and lifestyle changes. More complex conditions like IBD or long-standing IBS typically take 3-6 months of sustained change. What matters is building habits you can actually maintain long-term.

What foods are good for gut health?

The single biggest predictor of a healthy gut microbiome is plant food variety. Aim for 30 different plant foods per week. Fermented foods, prebiotic-rich vegetables, and oily fish are standouts. Ultra-processed foods, excessive alcohol, and low-fibre diets consistently reduce microbiome diversity.

Do I need to take probiotics?

Probiotics can be useful but are not the first thing most people need. The most impactful step for most people is increasing plant diversity in the diet, which feeds existing gut bacteria. If considering a supplement, getting guidance on the right strain for your specific situation is worthwhile.

Do I need to go gluten-free to improve my gut health?

Not unless you have coeliac disease or diagnosed non-coeliac gluten sensitivity. For most people, there is no evidence that removing gluten improves gut health. If you suspect gluten is a problem, get properly tested for coeliac disease before removing it from your diet.

What are fermented foods and should I be eating them?

Fermented foods including yoghurt, kefir, sauerkraut, kimchi, miso, and sourdough are among the most well-researched additions for gut health. Regular consumption increases microbiome diversity and reduces inflammatory markers. Most people benefit from including small amounts daily.

Why am I so bloated during perimenopause?

As oestrogen and progesterone fluctuate during perimenopause, digestion slows, gut motility changes, and the microbiome shifts. This means food sits in the digestive system longer, producing more gas. Targeted nutrition changes including increasing fibre and adding fermented foods can make a real difference.

How does the gut microbiome change during perimenopause and menopause?

As oestrogen declines, gut bacteria diversity tends to decrease, affecting digestion, metabolism, immune function, and mood. A less diverse microbiome is linked to increased inflammation and slower gut motility. Diet is one of the most powerful ways to support microbiome diversity at any life stage.

Can improving gut health help with perimenopause symptoms?

Yes. Gut bacteria called the estrobolome directly influence how the body processes oestrogen, meaning gut imbalances can intensify hot flushes, mood changes, and irregular cycles. Gut health also affects serotonin production, which influences mood, sleep, and anxiety. Focusing on gut health and managing hormonal symptoms are often the same goal.

I've cut out lots of foods but still have gut symptoms. What's going on?

Removing foods treats the symptom, not the cause. The underlying imbalance, whether dysbiosis, poor gut motility, or a disrupted gut barrier, is still there. Over time, excessive elimination reduces microbiome diversity, making the gut more reactive. The goal is to understand what is driving symptoms, not find more foods to cut out.

Can nutrition help with perimenopause symptoms beyond gut health?

Absolutely. Nutrition significantly impacts blood sugar balance, energy, mood, cravings, joint pain, brain fog, and muscle mass during perimenopause. Gut health also influences oestrogen metabolism, meaning what you eat can affect hormonal balance more than most people realise.

Why is fibre important for women in midlife, and how much do I need?

Fibre feeds beneficial gut bacteria, supports regular bowel movements, regulates blood sugar, reduces cholesterol, and plays a role in oestrogen metabolism. The recommended intake is around 25-30g per day, but most Australians fall well short. Increase gradually and focus on variety from vegetables, fruits, legumes, and wholegrains.

What foods help with bloating?

Foods that commonly support better digestion include fermented foods like yoghurt, kefir, and sauerkraut; cooked vegetables; ginger and peppermint tea; adequate water; and gradually increasing dietary fibre. Triggers vary from person to person, which is why identifying the underlying cause matters more than following a generic list.

What is the difference between IBD and IBS?

IBD (Crohn's disease and ulcerative colitis) is an autoimmune condition causing chronic inflammation and physical damage to the digestive tract, diagnosed through scopes and biopsies. IBS is a functional gut disorder with no visible structural damage. Both benefit from nutrition support but require different approaches. IBD also requires ongoing medical management.

What can I eat with IBD (Crohn's disease or ulcerative colitis)?

During a flare, focus on easily digestible, lower insoluble fibre foods such as well-cooked vegetables, white rice, eggs, fish, chicken, and bone broths. During remission, the goal shifts to rebuilding the microbiome, addressing nutrient deficiencies, and gradually increasing dietary variety. There is no single IBD diet as triggers vary widely between individuals.

Can diet help prevent or reduce IBD flares?

Diet does not cause IBD but can influence how often and how severely flares occur. An anti-inflammatory eating pattern emphasising oily fish, colourful vegetables, adequate protein, and fermented foods is well-supported. Ultra-processed foods, alcohol, and artificial emulsifiers are associated with increased inflammation and should be limited.

Is it safe to eat fibre when you have IBD?

During a flare, reducing insoluble fibre from raw vegetables, wholegrains, and skins may ease symptoms. Soluble fibre from oats, psyllium, and cooked carrots is often well-tolerated and supports gut healing. During remission, gradually reintroducing fibre variety is important for microbiome health and long-term inflammation reduction.

Are there foods I should avoid with IBD?

During flares, foods that commonly aggravate symptoms include raw vegetables, spicy foods, high-fat or fried foods, caffeine, alcohol, and dairy if lactose sensitive. Outside of flares, ultra-processed foods, artificial emulsifiers, and alcohol are worth limiting. Over-restriction is a common problem in IBD. The goal is the least restrictive diet that keeps you well.

What nutrients are commonly deficient in people with IBD?

Iron deficiency anaemia is one of the most common, caused by blood loss and poor absorption. Vitamin D, B12, folate, zinc, magnesium, and calcium are also frequently low, particularly in Crohn's disease where the small intestine is affected. These deficiencies affect immune function, mood, bone density, and overall disease management.

Chronic Constipated Causes No One Warns You About

Oct 1

3 min read

You're drinking more water.

You've added a fibre supplement, maybe two.

You've tried the magnesium everyone on Instagram swears by.

And you're still not going properly.

It's probably worth noting: if you've done the obvious stuff and nothing's changed, more fibre and more water was never going to be the answer. That advice gets handed out like it's universal wellness gospel, and for a huge number of people it simply doesn't work - not because they're doing it wrong, but because it was never addressing what's actually driving the chronic constipation in the first place.

I see this pattern constantly in clinic. A client comes in having already tried the 'obvious' things, and is frustrated with the lack of results. Feels like they are missing something simple. They are not. The advice they were given was incomplete.

A black wire shopping basket filled with fibre rich foods - broccoli, avocado, and brown rice, in a clear glass jar.

Why 'more fibre, more water' isn't the whole story in chronic constipation causes

Fibre and water really do matter for digestion - I'm not telling you to ignore them. But they only solve constipation caused by specific things: not enough bulk or moisture moving through the gut. For a lot of people, especially women in their 40s and 50s, that isn't what's going on at all. The real chronic constipation causes are often to do with how the gut is moving, not what's in it.

Gut motility - the "how fast is it moving" problem

Your gut has it's own nervous system, and it's own rhythm, and that rhythm can slow down for reasons that have nothing to do with diet. Stress, an underactive thyroid, low physical activity, some medications and overgrowth of certain microbiome populations can all slow gut transit time. If your gut is moving too slowly, adding more fibre without addressing the slowdown can actually make you feel more backed up and bloated, not less.

Hormones and the perimenopause shift

Progesterone and oestrogen both influence gut motility, and as they fluctuate through the 30s, 40s and into perimenopause, bowel patterns can change in ways that feel confusing and out of nowhere. If your constipation seems to have crept in alongside other shifts - sleep, energy, cycle changes - hormones are worth genuinely considering here.

The stress and nervous system link

Your gut and nervous system are in constant conversation. When you're in a stressed, 'on-guard' state a lot of the time, your body deprioritises digestion. This isn't in your head, and it isn't something more magnesium will override if the underlying stress load never gets addressed.

So what can you actually do?

Start by widening the lens beyond fibre and water:

Notice patterns. Does it get worse around your cycle, stressful weeks, or after certain medications? That pattern is valuable information
Movement matters more than most people expect - even a short daily walk can support gut motility
Pay attention to how you're going, not just whether you're going. Straining, a feeling of incomplete emptying, or needing to change position to poo are all worth mentioning to your practitioner
If pelvic flood tension feels like it might be part of the picture, a pelvic floor physiotherapist could be a useful referral - and this isn't something nutrition alone can fix
Get curious rather than more restrictive. Constipation is rarely caused by cutting things out - it's solved by understanding what's actually driving it

Chronic constipation is a message, not a personal failing. If you've already tried the 'fibre and water' advice and you're still stuck, that's not a sign you need to try harder. It's a sign you need more information.

If you want to actually work out what's driving your chronic constipation, a consultation is a good place to start - Book a Free Discovery Call, and we'll talk about what's really going on.
