Why your digestion changes with age

Why your digestion changes with age

As we get older, many of us notice subtle changes in how we feel on a daily basis.

Maybe your energy isn’t what it used to be. You feel more bloated after meals, your sleep feels lighter, your joints ache more, or you find yourself struggling with brain fog and feeling generally sluggish. Recovery from illness or stress can take longer too.

It’s easy to put these things down to ‘an age thing’ – and while ageing does play a role, there’s often something deeper happening beneath the surface: chronic, low-grade inflammation, sometimes referred to as ‘inflammaging’.

And very often, it starts in the gut.

Your gut – more than just digestion

Your gut isn’t simply where food is digested. It’s home to trillions of bacteria that influence your immune system, inflammation levels, mood, energy, and even brain function.

When the gut is balanced and functioning well, it helps keep inflammation under control. But as we age, that balance can begin to change.

What changes over time

Research shows that:

  • The balance of gut bacteria can shift, with fewer beneficial bacteria and more inflammatory strains developing
  • The variety of bacteria in the gut tends to decline
  • The gut produces fewer of the protective compounds that help calm inflammation
  • The gut lining can become more fragile and permeable

When this happens, unwanted substances can pass through the gut lining and into the bloodstream, triggering inflammation throughout the body.

And over time, this creates a cycle: The gut fuels inflammation, and this inflammation disrupts the gut. This is often linked to symptoms like:

  • Bloating 
  • Fatigue 
  • Sluggish bowels 
  • Brain fog 
  • Weakened immune system
  • Increased food sensitivities

Ways to support your body against ‘inflammaging’

There’s no single fix, but there are simple, effective ways to help your body.

These are the same foundations I’ve focused on for years:

2. Feed your gut properly (fibre really matters)

Fibre feeds your beneficial gut bacteria, helping them produce compounds that calm inflammation.

  • Try this simple shift: aim to eat more vegetables, whole foods, beans, oats, nuts, seeds, and fibre-rich meals each day but ensure that you also drink plenty of water to help push this extra fibre through your digestive system.

2. Support digestion itself

As we age, we naturally produce fewer digestive enzymes. This means food isn’t broken down as efficiently – particularly proteins and fats.

This is often why, as we age, we start to experience heaviness after meals, bloating, reflux, and the feeling that food ‘just sits there’.

  • Try adding our Digestive Enzymes tablets to your routine: supporting the breakdown of food, so nutrients are absorbed more efficiently, and the digestive system isn’t under unnecessary strain; all the more important if you are taking medication such as strong proton pump inhibitor drugs like omeprazole or lansoprazole that block the production of stomach acidTake one just before lunch and one just before dinner.

3. Rebuild and support your gut bacteria

Your microbiome plays a central role in regulating inflammation. But stress, medication, antibiotics, and ageing itself can reduce beneficial bacteria.

  • Redress the balance with our Live Bacteria: replenishing and supporting beneficial strains, helping to rebalance the gut environment and support both digestion and immune function. Take one capsule before breakfast and one before bed with a little water.

4. Don’t underestimate sleep

Sleep directly impacts the gut and immune system. When sleep is poor, gut balance shifts, the gut lining weakens, and inflammation increases.

  • Try this simple shift: aim for a more consistent sleep routine, earlier nights where possible, and a calmer wind-down before bed – ideally with less screen time. 

5. Support your nervous system

Your gut works best in a calm, ‘rest and digest’ state. Modern life often keeps us in the opposite – rushing, multitasking, and eating under stress.

  • Try this simple shift: slow breathing, gentle movement, walking outdoors, and even a few mindful moments during the day can help support both digestion and overall wellbeing. 

A final thought

Chronological ageing is inevitable, but illness is not. How your gut functions – and how you feel day to day – is something you can influence. Often, it’s not about doing more.

It’s about giving your body the support it now needs so that you can live well and independently as you age.

When I worked in clinic, I saw time and time again how much digestive health influences the way people feel as they get older.

At Just For Tummies, we regularly hear from people in their 50s, 60s, 70s and beyond who have been told by the medical profession that their IBS, bloating, constipation and acid reflux is to be expected with age – what rubbish! By making a few simple changes through our tailored advice and supplement protocols – such as improving their diet, supporting their gut bacteria, and taking Digestive Enzymes – our customers have noticed real improvements in their digestion, energy, comfort, clarity and overall wellbeing.

Your body doesn’t stop working as you age – it simply needs different support than it did before.  If you would like some guidance in figuring out what your body needs, please get in touch. We are here to help with tailored advice and recommendations.
