Signs of an Unhealthy Gut

Have you considered that your gut microbiome could be the culprit to symptoms or signs of poor health?We will discuss some signs that suggest your gut microbiota is imbalanced.

The gut microbiome is home to billions of bacteria and has a role in three main domains: digestion and absorption, immune function and gut-brain connection. There many different species of microbiota - some are beneficial and some can be harmful. For more about the ins and outs of our gut, read this article here.

There is 100 trillion micro-organisims that exist in the gastrointestinal tract.

When there is an imbalance of microbiota or an excesse of harmful species, it can lead to adverse effects on our health. Some signs or symptoms may include:

  • food allergies or intolerances

  • altered bowel habits such as diarrhoea or constipation

  • abdominal bloating

  • excessive flatulence or wind

  • respiratory symptoms such as sinus congestion, asthma, throat irritation)

  • skin conditions such as acne, eczema, swelling

  • poor sleep

  • fatigue

  • nausea or headaches

  • weakened immune system

  • heart burn

  • mouth ulcers

  • poor mental health such as anxiety, depression and mood swings

Diet has a significant role in optimising good gut health. Studies have shown that a diet rich in fibre, low in red meat and processed meats and probiotics promote healthy micorbiota growth.

However, we are all unique and so is our micorbiome. Therefore there is no one-size-fits-all approach when it comes to a gut nourishing diet.

For some people, specific foods (e.g. FODMAP, food chemicals) should be avoided to reduce symptoms that impacts quality of life. To read more about food intolerances, read this article here.

If you aren't sure where to start, book an appointment with our dietitians to help develop a gut nourishing plan.
