Have you ever felt anxious in your body even when nothing obvious is wrong?
For many people, anxiety is not only experienced as racing thoughts or worry. It can show up very physically in the body. When this happens it can feel confusing, especially if you are trying to take care of your health and still do not feel quite right.
Common Physical Symptoms of Anxiety
People often describe symptoms such as:
A racing or pounding heart
Tightness in the chest
Feeling shaky or trembling
Sweating or feeling on edge
Digestive discomfort or abdominal distress
A sense of restlessness or internal tension
Experiences vary from person to person, but these physical sensations can feel very real
and unsettling.
Understanding the Gut-Brain Connection
Many people assume anxiety is purely psychological.
However, the body is a connected system. The gut and brain are closely linked through
what is known as the gut-brain axis. This is a communication network between the
digestive system and the brain.
Because of this connection, what is happening in the body can sometimes influence how
we feel mentally and emotionally and vice-versa.
When the body feels under pressure, whether through poor sleep, nutritional imbalances, digestive issues or lifestyle stress, the nervous system may remain in a heightened state.
This can contribute to the physical sensations many people describe as anxiety.
How I Think About This as a Nutritional Therapist
When someone comes to see me with symptoms like these, I like to look at the ‘whole person’, look deeper into the different systems of the body and how they interplay with each other, ultimately looking for the root cause of why these symptoms are happening.
For example, I will question:
Whether someone may be low in key nutrients or not absorbing them as well as they could be
Whether there may be inflammation affecting the body
The balance of sugar and processed foods in the diet
How much coffee or alcohol someone is drinking
The quality and consistency of sleep
Stresses that they may be experiencing
The frequency and timings of meals throughout the day
All these factors can influence how supported or stressed the body feels.
The aim is not to search for something wrong, but to understand what may help the body feel more balanced and supported.
Functional Testing That May Be Helpful to Explore
In some situations, functional testing can provide additional insight into what might be happening in the body.
This is not always necessary, but it can sometimes help to guide a more personalised approach.
Depending on the individual situation, this may include:
Blood tests to review nutrient levels and general health markers
Stool testing to explore digestive health and the balance of the gut microbiome
Other assessments that help explore digestion, inflammation or nutrient status
Testing is always considered carefully and interpreted in context. It is simply one tool that can help us understand the bigger picture of someone’s health.

If some of these experiences sound familiar, there are a few simple steps that may help support your body.
1. Eat regular, balanced meals
Include protein, fibre and healthy fats to help support steady energy and nourishment.
2. Notice how caffeine, alcohol and sugar affect how you feel
These can sometimes influence the nervous system and energy levels.
3. Prioritise sleep and simple nourishing meals where possible
Rest and nourishment provide important support for the nervous system.
Small changes practiced consistently often make a meaningful difference over time.
A Final Thought
When the body feels nourished, rested and supported, the nervous system often begins
to settle too.
If you recognise some of these experiences in yourself, please know that you are not
alone. Many people experience anxiety through physical symptoms, and it can be helpful
to look at the whole picture of health.
Client Experience
“Cath has honestly changed my life.”
“I had spent the whole of last year going to the gym four to five times a week and feeling deflated when I saw I hadn’t lost any weight, or had even gained a few pounds. I thought something was wrong with me.
I came to Cath with the mindset that if working on my nutrition didn’t help, there must be something terribly wrong with me.
I am pleased to say that with Cath’s incredible knowledge, informative personalised plan and weekly support, I have lost a stone within the time we’ve worked together.
I feel so pleased that I decided to invest in Cath and my nutrition. I have completely changed my lifestyle for the better and now have the tools and information to continue
my weight loss journey in a sustainable way.
I also feel so much better in myself. I no longer have tension headaches, and I feel far
more motivated and positive.
Honestly Cath, I can’t thank you enough.
If you are struggling with your weight, or anything to do with your health, I highly recommend contacting Cath for support.”
