Understanding the causes of IBS: insights and solutions

Did you know that Irritable Bowel Syndrome (IBS) affects approximately 10-15% of the global population? Despite its prevalence, many people are unaware of the various underlying causes that contribute to this common gastrointestinal disorder. Understanding the triggers for IBS is crucial as it can lead to effective management and an improved quality of life.
 
What is IBS?
 
Irritable Bowel Syndrome (IBS) is a chronic condition affecting the large intestine, leading to a variety of digestive symptoms, including abdominal pain, bloating, gas, diarrhoea, and constipation. The onset of IBS is often gradual, and symptoms can vary greatly from person to person.

​Understanding the Different Types of IBS
 
IBS can generally be classified into three main subtypes:
  • IBS-D (Diarrhoea-predominant): Characterised by frequent loose stools and urgency
  • IBS-C (Constipation-predominant): Characterised by infrequent bowel movements and hard stools
  • IBS-M (Mixed): A combination of both diarrhoea and constipation
​The key causes of IBS

1. Diet and Food Intolerances
Diet, and intolerances to certain foods, can trigger IBS symptoms. Common culprits include:
  • Dairy products, in cases of lactose intolerance
  • Gluten, especially for individuals with gluten sensitivities
  • Highly processed foods that contain artificial ingredients and preservatives
 Keeping a food diary can help identify personal triggers.
 
2. Gut Health and Microbiome
  • The gut microbiome plays a significant role in overall digestive health. An imbalance in gut bacteria may lead to inflammatory responses, which can exacerbate IBS symptoms
  • Probiotics and prebiotics are often recommended to restore balance and improve intestinal health. Foods high in fibre, such as fruits, vegetables, and whole grains, can support the growth of beneficial gut bacteria
 
3. Stress and Mental Health
  • There's a strong connection between the gut and the brain. Stress, anxiety, and depression can significantly affect gut function. When individuals experience high stress levels, it can lead to changes in gut motility and promote gut sensitivity
  • Management techniques such as mindfulness, cognitive behavioral therapy (CBT), and exercise can be beneficial in reducing stress and its impact on IBS symptoms
 
4. Hormonal Changes
  • Many women report worsening IBS symptoms during their menstrual cycles or after the menopause. Hormonal fluctuations can affect gut motility and sensitivity, linking hormonal changes to IBS severity
  • Understanding your menstrual cycle and tracking symptoms may highlight correlations and assist with symptom management during specific phases
 
5. Other Medical Conditions
  • Chronic conditions, such as coeliac disease, inflammatory bowel disease (IBD), or gastroesophageal reflux disease (GERD), can complicate the diagnosis and management of IBS
  • It’s essential to work with a healthcare provider to rule out these conditions and ensure an accurate diagnosis
  
As you work towards better managing IBS, it's crucial to stay proactive. Arm yourself with knowledge about your condition and be prepared to adapt your strategies as needed. If further help is needed, make an appointment to see me to get digestive and lifestyle support.
