The weird way your gut and brain talk

Jane Arlow • April 14, 2025

Wanna calm the chat down?

So here’s a weird question:


Have you ever been really stressed... and then your tummy went rogue?


Bloating, cramping, weird appetite swings, digestion slower than a slug after falling into a pint of beer?


It's not just coincidence - it's your gut and brain doing their usual double act


Your brain and your gut are BFF (whether you like it or not)

Inside your body is a magic highway called the gut-brain axis, and it's a two-way chat line between your digestive system and your nervous system.


You've heard of the sympathetic nervous system (fight/ flight/ freeze) and parasympathetic nervous system (rest/digest).


But you might not have heard of the enteric nervous system. This is the part of your nervous system that directs the work of digesting food.


Together, these three branches are known as the autonomic nervous system (ANS).


How do they communicate?

I said it's like a chat line. And that chat line is called the vagus nerve. It communicates between the brain and all three branches of the ANS.


It’s like your body’s in-built therapist—as well as regulating digestion, it also calms things down, manages inflammation, and generally helps you feel okay. 


So when you’re stressed—mentally, emotionally, physically—the chat line starts sending messages and things get a bit off.


What happens when you're stressed?

Your sympathetic nervous system tells your body to divert energy away from digestion and into emergency mode.


So suddenly:

  • You’re eating, but not really digesting.
  • You’re bloated for no reason.
  • Your appetite’s up/down/nowhere.
  • You feel wired and weirdly sluggish.



How do you calm the chaos?

By engaging the parasympathetic nervous system—aka rest and digest mode.


We want to be here more often.


Because this is when:

✅ Your gut functions properly
✅ Your 
neurotransmitters (like serotonin and dopamine) balance out
✅ You stop feeling like a fizzy can of stress and start feeling like yourself


And guess what helps activate the vagus nerve?

Err, all the things we've been talking about in the last few blogs:

✨ Breathwork 

 ✨ Humming/ singing

✨ Moving 

✨ Cold water

 ✨ Reflection/ mindfulness/ meditation

✨ Taking time to just be in your body



How does Pilates help activate the vagus nerve?

We're breathing properly. We're moving. We're being mindful as we pay attention to our body.


Want to feel a bit more balanced—gut, brain, and everything in between?

Come and try it. Your nervous system will thank you. Your digestion probably will too.


Not only will you calm your nervous system, you'll also feel physically better in your back and hips. It's an absolute win-win!

October's Breast Cancer Awareness Month and if you haven't done it recently, please let this be the nudge you need to give them a good feel up. Here 's a link to the NHS website below showing how to perform your check and what to look for. If you're one of my gentlemen readers, please don't think this doesn't apply to you. It does. Men can still get breast cancer. And if you find something that doesn't seem right, please contact your GP as soon as possible. 80-90% of lumps are likely to be benign, but for the small percentage of those that aren't, early detection and treatment are your best chances of having successful treatment and being around to annoy friends and family for a long time. Don't skip your mammogram I know having mammograms is really uncomfortable. But this is one of the best ways to check for cancers that aren't otherwise easily spotted. So if you get invited, please go. (And don't skip your smear test either!!!) Know your risk factors 1 in 7 women will get breast cancer in their lifetime. Here are some of the risk factors: - Age : older women are more likely to get breast cancer than younger women and age is the highest risk factor. - Genetics : Breast cancer risk is higher if you have first-degree relatives who've had it (although 85% of women with a relative with breast cancer WON'T get it). - Breast density (relates to the percentage of non-fatty tissue): the risk is highest for those with the most dense tissue. You can ask your radiographer to tell you whether you have dense tissue at your mammogram. - Lifestyle factors: These include having overweight or obesity, alcohol consumption, tobacco use and insufficient physical activity. - Exposure to endocrine disrupting chemicals: These "forever" chemicals, such as pthalates and parabens, show up in makeup and toiletries. Risk doesn't normally come from one exposure to one chemical, but from prolonged exposure to many different chemicals over a long period of time. You can read more about the risks here It's worth noting that even if you get a diagnosis, it's unlikely you'll ever know if there was "one thing" that caused it. What happens if you get a diagnosis of breast cancer? I am in no way competent to comment on the treatment plan your medical team recommend for you. Everyone I know who's had breast cancer has had a different treatment plan, depending on: the stage of cancer; whether it had spread further; whether it was hormone-receptive; whether it was due to genetic mutation; and the age of the woman. I do know that for all of us, it was a really scary time. You should be given access to resources outside of the surgical and oncology team, often via a Macmillan nurse, who can answer questions on topics from your treatment and reactions, to claiming for extra benefits. They're also great if you're not sure what questions to ask. While you're in the heat of the panic, it can be difficult to think clearly about what you need to know. Using "what should I be asking that I'm not?" is super helpful. Keep moving after your diagnosis, during and after treatment The one thing I can advise you on with all confidence, is to keep moving. Exercise is safe, possible and helpful for individuals with breast cancer, throughout the treatment cycle. In fact, international guidelines say you should try to get back to your normal activities as soon as possible. Exercise can help reduce the risk of cancer coming back; and may stop stage 1 cancers from growing further; and can also reduce treatment side effects like tiredness, cognitive impairment or lympoedema. Yes, you may need to dial back your usual activities if treatment leaves you feeling exhausted. But whenever you can, please aim for 150 minutes of exercise in every week. Many forms of treatment also lead to a higher osteoporosis risk, so please also do resistance-based and/or some impact-based exercise every week. I'd also recommend paying attention to shoulder mobility. Scar tissue and "guarding" of surgery sites can reduce your range of movement a lot. Check in with your medical team to confirm if there's any specific movements you should avoid during your treatment plan, and when you'll be signed off to go back to them. One last piece of advice someone else gave me... When you tell people you have cancer, a lot of them will have an opinion on your treatment plan. Especially if they're of the "my friend cured their cancer by just eating this one thing.." type. Unless this person is an oncologist, you can safely ignore them! So, what are you still doing reading this? Go off and give yourself a fondle!
