When Your Gut Feels Off and You Keep Getting Ill: How Nutritional Therapy Can Help
A woman choosing supplements from a shelf
Do you find yourself feeling constantly run down, struggling with sluggish digestion, and catching every cold that comes your way? If that sounds familiar, you are not alone. Many people live with these kinds of symptoms for months or even years before realising that their gut health could be at the root of it all.
The good news is that practical, sustainable changes can make a real difference. You do not need an overhaul of your entire lifestyle. Sometimes a few well-chosen adjustments are enough to shift how you feel in a significant way.
What your gut has to do with your immunity
Your digestive system does far more than process food. It plays a central role in how your body defends itself. When your gut is not functioning well, it can affect your energy, your mood and how well your body copes with the bugs and stresses it encounters every day.
Constipation, frequent illness and feeling generally run down are often connected. When digestion slows, the body can struggle to absorb nutrients effectively, which in turn can affect immune resilience. It is rarely one single cause, which is why taking a whole-person approach tends to get the best results.
Common signs your gut may need some support
These symptoms are easy to brush off, but they are worth paying attention to:
Persistent or frequent constipation
Feeling tired or run down without a clear reason
Getting ill often, particularly through autumn and winter
Bloating or discomfort after eating
Slow recovery after illness
A general sense of not feeling your best
If several of these feel familiar, your gut health could be a useful place to start.
How I approach this as a nutritional therapist
When a client comes to me with symptoms like these, I want to understand the full picture before making any suggestions. That means looking at what they eat, how they live, how they sleep and what their digestion is actually doing day to day.
From there, we build a plan that is practical and realistic. This will definitely not involve complicated protocols or restrictive diets that are difficult to maintain. What tends to work best are small, meaningful changes that fit naturally into everyday life.
For many clients, this includes increasing the diversity and volume of plant foods, particularly seeds, which can have a gentle but noticeable impact on digestion. A personalised supplement plan is also something I consider, especially where there may be specific nutritional gaps that diet alone is not addressing. My client below only needed omega 3 and vitamin D supplements, nothing fancy, just quality products given at the right dose to be effective and taken correctly to ensure absorption.
When functional testing might be worth exploring
Functional testing is not always necessary, but it can be a genuinely useful tool when symptoms are persistent or when we want to understand more about what is happening beneath the surface.
Depending on your situation, it may be worth exploring tests that look at gut microbiome health and digestive function, nutritional status and any potential deficiencies, or markers related to inflammation and immune activity.
These tests are never about jumping to conclusions. They are about gathering information that helps us make more informed, targeted decisions together. I always discuss whether testing is appropriate before recommending it, and it is never a compulsory part of working with me.
A client's experience
I can't recommend my nutritional therapist highly enough. She has made a huge difference to my gut health and overall wellbeing.
Before seeing her, I was struggling with persistent constipation and seemed to be picking up one illness after another which is just not me. I often felt run down and was frustrated by how frequently I was getting sick and needing time off-work.
One of the key changes she suggested was increasing both the diversity and volume of seeds in my diet.
This had a noticeable impact on my digestion and significantly improved my gut health.
She also recommended a tailored supplement programme, which has been enormously beneficial. In particular, I've felt much healthier over the winter period and managed to avoid the usual seasonal illnesses altogether.
Her advice has been practical, evidence-based, and easy to implement, and the results have exceeded my expectations. I would 100% recommend her to anyone looking to improve their gut health and overall wellness.
Three practical steps to consider
If you are looking for somewhere to start, here are three things that many of my clients find genuinely helpful:
Increase seed diversity in your diet. Try adding a mix of flaxseeds, chia seeds, pumpkin seeds and sunflower seeds to meals. Rotating variety matters as much as volume.
Think about the range of plant foods on your plate. Gut health tends to thrive on variety. Aiming for a wider spread of vegetables, wholegrains, legumes and nuts each week is a simple but effective place to focus.
Get some guidance on supplements. Rather than buying products based on general advice, it is worth speaking to a professional about what might actually be relevant to your specific needs, how and when to take it to ensure optimal absorption and that there are no interactions with any prescribed medications.

If any of this resonates with you, I would love to help. Whether you are dealing with ongoing digestive issues, feeling run down through the colder months or simply not feeling like yourself, nutritional therapy could be a helpful next step.

Why Gut Health Matters
Your gut influences digestion, immunity, and even mood. Poor gut health can cause bloating, fatigue, digestive discomfort, recurrent infections and low mood. Including gut-friendly foods in your diet helps maintain a healthy balance of bacteria and improves overall wellness. Here are the top 5 foods to support your gut naturally.
Top 5 Gut-Friendly Foods
1. Yogurt
Rich in probiotics (live bacteria), yogurt introduces beneficial bacteria to your gut, improving digestion and nutrient absorption. Choose unflavoured Greek yoghurt to maximise protein intake.
2. Sauerkraut and Kimchi
Fermented foods contain live bacteria that enhance gut flora and boost immunity. If these are new foods for you, start by adding a tablespoon to lunch. Cheese on toast with kimchi and a side salad is a good place to start.
3. Oats
High in soluble fibre, oats feed the good bacteria in your gut and aid regular digestion. Always choose organic, whole-rolled oats as oat crops grown in damp climates may be sprayed with Glyphosate.
4. Garlic and Onions
These prebiotic-rich foods nourish beneficial bacteria and help maintain gut balance. Include all members of the onion family so chives, spring onions, leeks, red, brown and white onions! Ready-chopped frozen onions are time-savers for soups, stews and curries.
5. Berries
Packed with antioxidants and fibre, berries promote healthy gut bacteria and reduce inflammation. They are low sugar fruits too.
Tips to Incorporate These Foods
Add yogurt or kefir to snacks, breakfast or smoothies or as side to curries and kebabs
Include fermented vegetables as side dishes
Use oats in homemade granola, whizzed up as flour for pancakes, with nuts and seeds for breakfasts or in home-made cereal bars for healthy snacks
Add garlic and onions to meals for flavor and prebiotic benefits
Snack on berries or add to cereals, smoothies and yoghurt
