2 / Bloating, Constipation or Reflux? Where to Start

Once you understand that digestive symptoms can come from different parts of the digestive process, the next question is obvious: What do I actually do about them?

This is where I don't want you starting with a probiotic, cutting out gluten, buying digestive enzymes and drinking litres of water because somebody told you to "heal your gut." Bloating, constipation and reflux may occur together, but they are not the same problem and they don't necessarily have the same solution.

The first step is to work out which symptom is dominant, when it happens and what seems to make it better or worse. That gives us somewhere sensible to start.

Before changing anything, watch your gut for one week

For seven days, pay attention to your digestive pattern without trying to fix it.

Notice when symptoms occur in relation to meals. Do you wake feeling comfortable and become progressively bloated during the day? Does bloating begin within minutes of eating? Does it improve after passing stool or gas? Does reflux occur after large meals, when you lie down or after alcohol? How often do you have a bowel movement and what does it actually look like?

The Bristol Stool Chart is useful here. It classifies stools from type 1, separate hard pellets, through types 3 and 4, which are generally considered normal formed stools, to type 7, entirely liquid stool. It gives us considerably more information than simply saying, "My digestion isn't great."

Also note medications and supplements. Iron, opioids, some antidepressants, anticholinergic medications and other drugs can affect bowel function, while medications and supplements can also contribute to reflux or diarrhoea.

You don't need to document every almond you eat but look for patterns.

If constipation is the main problem, define constipation first

Constipation doesn't simply mean that you don't go every day.

Normal bowel frequency varies between people. What matters is whether you regularly have hard or lumpy stools, excessive straining, a feeling of incomplete evacuation, a sensation that something is blocking the stool, or bowel movements that are significantly less frequent than is normal for you.

Once we know that, we can ask why.

Start with the basics. Are you eating enough food? Is there sufficient fibre in your diet? Are you drinking adequately? Are you physically active? Are you repeatedly ignoring the urge to go? Has a new medication or supplement coincided with the change?

If your diet is very low in fibre, increasing it can improve constipation. But more fibre is not always better, particularly if you suddenly increase it dramatically. Going from very little fibre to enormous bowls of bran, seeds and raw vegetables overnight can leave an already bloated woman feeling considerably worse.

Increase fibre gradually and give your digestive system time to adapt.

Choose fibre more intelligently

Different fibres behave differently in the gut.

Soluble fibre absorbs water and forms a gel-like substance. Psyllium is a particularly useful example and has good evidence for improving stool consistency and constipation. Oats, legumes, fruit and many vegetables also contain varying amounts of soluble and fermentable fibres.

Insoluble fibre adds bulk and can help move material through the bowel, but large quantities of coarse fibre are not necessarily comfortable for everyone, particularly when significant bloating or IBS is present.

Then there are fermentable fibres that gut microorganisms use as substrates. These can support beneficial microbial activity, but fermentation also produces gas.

This is why I don't want you chasing an arbitrary fibre number while ignoring what your gut is telling you.

The long-term aim is a varied, fibre-rich diet. How quickly you get there depends on the gut you currently have.

Water matters, but drinking more isn't always the answer

If you are dehydrated, improving fluid intake can help stool remain softer.

But there is little sense in telling a woman who already drinks two litres of water every day that her constipation will disappear if she drinks three.

Hydration is one part of bowel function. Fibre, food intake, physical activity, intestinal motility, medications and pelvic-floor coordination matter too.

This is a theme you will hear repeatedly in this series: find the bottleneck instead of endlessly increasing something that is already adequate.

Use the gastrocolic reflex instead of fighting your body

There is a useful physiological response called the gastrocolic reflex. When food enters and stretches the stomach, signals increase colonic motility and can create an urge to have a bowel movement.

This response can be particularly noticeable after breakfast.

If you regularly feel the urge to go after eating but ignore it because you're rushing to work, getting children organised or simply don't like using a toilet outside your home, you may be repeatedly overriding one of your body's natural opportunities to empty the bowel.

Give yourself time after breakfast or another substantial meal. Sit without rushing. A small footstool that raises your knees above your hips can also make the position more favourable for evacuation.

Sometimes supporting normal physiology is more useful than trying to stimulate the bowel artificially.

If you can feel the stool but cannot get it out, think pelvic floor

This is where adding more fibre can completely miss the point.

Normally, the pelvic-floor muscles involved in defecation need to relax and coordinate with increased abdominal pressure so stool can pass.

In a defecatory disorder, those muscles may fail to relax appropriately or may contract when they should be relaxing.

A clue is repeated straining, a feeling of blockage or incomplete evacuation even when stool isn't particularly hard. Some women need to change position repeatedly or use manual manoeuvres to empty the rectum.

If that sounds familiar, don't assume you simply need a stronger laxative.

Assessment by an appropriately trained clinician and pelvic-floor physiotherapy or biofeedback therapy can be far more relevant because the problem may be coordination rather than stool production.

If bloating is the problem, timing gives us clues

Bloating requires a slightly different approach.

If you wake relatively comfortable and become progressively more bloated throughout the day, think about what is accumulating as the day progresses: meals, fermentable carbohydrates, gas and stool.

Constipation itself is an extremely common contributor to bloating. If the bowel isn't emptying effectively, dealing with constipation may improve the bloating without needing an entirely separate "anti-bloat protocol."

If bloating appears consistently after particular foods, keep track of the pattern before removing them.

Onions, garlic, wheat products, certain fruits, legumes and some dairy products can cause symptoms in susceptible people because of the types of carbohydrates they contain. Many fall into the group known as FODMAPs, fermentable carbohydrates that can be poorly absorbed and rapidly fermented.

That does not mean those foods are unhealthy.

It means your current digestive system may not tolerate certain quantities of them particularly well.

Don't start by removing gluten, dairy and half your vegetables

This is one of the quickest ways for a simple digestive problem to become an unnecessarily complicated diet.

If you repeatedly react to a particular food, investigate the pattern.

If gluten appears to be the problem, don't remove it before being tested for coeliac disease if coeliac disease is a possibility. Coeliac blood testing is most accurate while you are still consuming gluten. Removing gluten beforehand can interfere with diagnosis.

If dairy causes bloating, consider whether lactose may be the issue rather than deciding you are "dairy intolerant." Hard cheeses, for example, contain very little lactose compared with milk.

A structured low-FODMAP diet can be extremely useful for some people with IBS, but it is designed as a temporary elimination followed by systematic reintroduction, ideally with appropriate professional guidance. It was never intended to become a permanently tiny list of safe foods.

The objective is to eat the broadest diet you comfortably tolerate, not to win a competition for how many foods you can eliminate.

If reflux is the problem, start with mechanics

Reflux requires a different strategy again.

If stomach contents repeatedly move upwards into the oesophagus, start by looking at when that happens.

Large meals increase stomach distension and can worsen reflux in susceptible people. Eating close to bedtime makes it easier for reflux to occur once you lie down. Alcohol can worsen symptoms in some people, and particular foods may trigger symptoms individually.

If reflux primarily occurs at night, try finishing your evening meal approximately three hours before lying down. Smaller evening meals can also help.

For persistent nighttime reflux, elevating the head end of the bed can reduce nocturnal symptoms. That means raising the upper body effectively rather than simply piling several pillows under your head, which may not produce the same effect.

If carrying excess abdominal weight is contributing to increased intra-abdominal pressure, weight reduction can substantially improve reflux in some people.

None of these strategies requires you to decide whether you have "too much" or "too little" stomach acid.

Don't start taking betaine HCl because somebody told you stomach acid declines with age

This deserves repeating from Article 1.

Low gastric acid can occur, particularly with atrophic gastritis, certain medical conditions and acid-suppressing medication. But reflux itself does not prove that you have insufficient stomach acid.

Taking betaine hydrochloride, or HCl, without knowing what is happening can aggravate symptoms and is inappropriate in some gastrointestinal conditions or alongside certain medications.

If you have persistent reflux, especially if it is new or worsening, investigate it properly rather than conducting an acid experiment on yourself.

What about antacids and proton pump inhibitors?

Acid-suppressing medication has a legitimate role.

Proton pump inhibitors, or PPIs, reduce gastric acid production and are highly effective treatments for gastro-oesophageal reflux disease and several other acid-related conditions. They are not inherently "bad for the gut," as they are sometimes portrayed online.

But medication should have an indication.

If you have been taking a PPI long term, it is reasonable to periodically review with your doctor whether you still need it, whether the dose remains appropriate and whether the original indication still exists.

Do not suddenly stop long-term acid suppression on your own. Rebound acid hypersecretion can occur after withdrawal and make symptoms temporarily worse.

The functional approach here isn't "medication bad, natural remedy good."

It is use the appropriate treatment for the appropriate reason.

Where do probiotics fit?

Probably later than most people think.

Probiotics are not one treatment. Different strains can have different biological effects, and evidence varies substantially according to the condition, strain, dose and outcome being studied.

A probiotic that has evidence for one specific gastrointestinal problem cannot automatically be assumed to treat constipation, bloating, reflux and diarrhoea.

Some people feel better taking probiotics. Some notice absolutely nothing. Some become considerably more bloated.

So if your first response to every digestive symptom is buying another bottle containing 30 billion bacteria, stop for a moment.

What problem are you trying to treat?

That question should come before choosing the product.

We will look more closely at probiotics and how to support the microbiome in Article 3.

Move your body because your bowel moves too

Physical activity supports much more than cardiovascular and metabolic health.

Regular movement can support bowel motility, and exercise is associated with improvements in constipation in some people.

You do not need a special gut workout.

Walking is a very good place to start, particularly if you currently spend large portions of the day sitting. A short walk after meals has the additional advantage of supporting post-meal glucose regulation.

This is another reason I prefer simple interventions that support several physiological systems simultaneously.

Your gut does not live separately from the rest of your body.

What about stress?

If your digestive symptoms reliably worsen during periods of stress, don't ignore that pattern.

Through the gut-brain axis, psychological stress can influence motility, secretion, visceral sensitivity and digestive symptoms. In IBS particularly, gut-brain interactions are central to the condition.

But I don't want you to interpret this as "relax and your stomach problems will disappear."

Instead, recognise stress as one possible physiological amplifier.

Eating every meal while answering emails, barely chewing and rushing back to work gives your digestive system a different environment from sitting down, slowing your breathing and actually paying attention to your food.

You don't need a twenty-minute pre-meal meditation.

Sometimes you simply need to sit down and eat.

Bloating and constipation: When is it time to stop experimenting and get investigated?

There is a point where another dietary change isn't the answer.

Seek medical assessment for blood in the stool, black stools, unexplained weight loss, persistent vomiting, difficulty or pain when swallowing, iron-deficiency anaemia, severe or persistent abdominal pain or a significant persistent change in bowel habits.

New or progressively worsening digestive symptoms also deserve more attention with increasing age, even when no obvious alarm symptom is present.

And persistent reflux shouldn't simply be self-treated indefinitely. Long-standing reflux can damage the oesophagus and, in some people, requires further investigation.

If something has significantly changed and isn't improving, investigate it.

Your first gut plan

Don't try to fix your entire digestive system at once.

For the next couple of weeks, identify your dominant symptom and start there.

If it is constipation, assess stool consistency, fibre, fluids, food intake, movement, medication and whether evacuation itself is difficult.

If it is bloating, look at timing, constipation, portion size and reproducible food triggers before eliminating foods.

If it is reflux, look at meal size, evening meal timing, alcohol, individual triggers and what happens when you lie down.

And if symptoms are persistent, unusual or accompanied by warning signs, move from self-experimentation to investigation.

That is enough for now.

What I want you to take away from this

You don't need to "heal your entire gut" because you are bloated or constipated. Identify the symptom, understand the pattern and address the most obvious physiological problem first. Small, targeted changes often tell us much more than changing ten things simultaneously.

Once those foundations are in place, we can go deeper. In the next article, we'll look at what actually supports a resilient digestive system: microbial diversity, different types of fibre, short-chain fatty acids, the intestinal barrier, fermented foods, polyphenols and probiotics, and separate useful gut science from some of the very expensive nonsense surrounding it.
