Small Intestinal Bacterial Overgrowth is a condition that is increasingly recognised as a contributor to persistent digestive symptoms. Many people live with bloating, abdominal discomfort or irregular bowel habits without realising that bacterial overgrowth in the small intestine may be involved. In this article, we explore what Small Intestinal Bacterial Overgrowth (SIBO) is, why it develops, and how a personalised digestive approach can support long-term gut comfort. You can explore my approach to digestive health on my website, including the About Melody, Nutrition Coaching, and Work With Me sections.
What Is Small Intestinal Bacterial Overgrowth
Small Intestinal Bacterial Overgrowth (SIBO) occurs when bacteria that normally belong in the large intestine migrate into the small intestine. The small intestine is designed for nutrient absorption, not fermentation. When excess bacteria are present, food is fermented too early, often leading to uncomfortable digestive symptoms.
Unlike short-term digestive upset, Small Intestinal Bacterial Overgrowth (SIBO) may persist if underlying contributors are not addressed. This is why many individuals find their symptoms return even after temporary relief.
Through my work with clients, Small Intestinal Bacterial Overgrowth (SIBO) is often part of a wider digestive picture that requires careful, personalised support.
Common Symptoms of Small Intestinal Bacterial Overgrowth
Small Intestinal Bacterial Overgrowth (SIBO) may present differently from person to person, but common symptoms include:
- Bloating and visible abdominal distension
- Gas and pressure
- Abdominal pain or discomfort
- Diarrhoea, constipation, or alternating bowel habits
- Fatigue or brain fog
Because symptoms overlap with other digestive conditions, Small Intestinal Bacterial Overgrowth (SIBO)is frequently overlooked or misidentified.
Why Small Intestinal Bacterial Overgrowth SIBO Develops
Several factors may contribute to the development of Small Intestinal Bacterial Overgrowth (SIBO):
1. Reduced Gut Motility
When movement through the digestive tract slows, bacteria have more opportunity to accumulate in the small intestine.
2. Digestive Secretions
Adequate digestive secretions help control bacterial balance. Disruption can influence bacterial growth patterns.
3. Structural or Functional Digestive Changes
Previous digestive illness or ongoing digestive stress may increase susceptibility to Small Intestinal Bacterial Overgrowth (SIBO).
4. Diet and Fibre Intake
Fibre plays a role in supporting gut motility and microbial balance. Too little or poorly tolerated fibre may influence symptoms.
Understanding these factors helps explain why Small Intestinal Bacterial Overgrowth SIBO often requires more than a surface-level approach.
The Role of Diet and Fibre in Small Intestinal Bacterial Overgrowth
Dietary choices play an important role in managing symptoms associated with Small Intestinal Bacterial Overgrowth (SIBO). Certain fermentable foods may worsen symptoms for some individuals, while others may tolerate them well.
Rather than focusing on restriction, a supportive approach aims to:
- Identify individual tolerance patterns
- Maintain adequate fibre intake without aggravating symptoms
- Encourage regular digestion and gut motility
This balance helps support digestive function while reducing discomfort linked to Small Intestinal Bacterial Overgrowth (SIBO).
Why Personalised Support Matters for Small Intestinal Bacterial Overgrowth SIBO
Small Intestinal Bacterial Overgrowth (SIBO)is rarely caused by a single factor. Without addressing underlying contributors such as motility, stress, eating patterns and digestive resilience, symptoms may continue.
Through my personalised programmes clients explore their digestive history, symptom patterns and lifestyle factors in depth. This allows for a tailored strategy that supports gut function without unnecessary restriction.

Supporting Digestive Comfort with Small Intestinal Bacterial Overgrowth
Supportive strategies for Small Intestinal Bacterial Overgrowth (SIBO)may include:
- Regular meal timing to support gut motility
- Mindful eating and thorough chewing
- Gradual fibre adjustments based on tolerance
- Stress management to support the gut-brain connection
When applied in a personalised way, these strategies can help reduce symptom severity and improve digestive comfort over time.
Final Thoughts
Small Intestinal Bacterial Overgrowth (SIBO) can be frustrating, especially when symptoms linger without clear answers. With personalised guidance and a whole-digestive approach, it is possible to understand contributing factors and support long-term gut comfort.
