What is SIBO?
Small Intestinal Bacterial Overgrowth (SIBO) is a condition affecting the small intestine. SIBO is caused when bacteria that normally grow in other parts of the gut start growing in the small intestine. It typically causes pain and diarrhea. Experts estimate that up to 80% of Irritable Bowel Syndrome (IBS) sufferers may actually have SIBO. Some people with inflammatory bowel disease may also have SIBO. Here are some common symptoms of SIBO:
- Cramping and pain
- Cramps after eating, indigestion
- Alternating diarrhea and constipation
- Food sensitivities
- Regular feeling of fullness
- Nutrient deficiencies
- Consuming grains, fibre, starches, legumes may make symptoms worse
Instead of allowing the villi and microvilli to absorb nutrients from the food in the small intestine, the bacteria digest it instead, causing it to ferment. Not only that, but SIBO can also lead to damage to the villi and microvilli. This can lead to malabsorption of a variety of nutrients, especially B12, folic acid, magnesium, iron and calcium.
These gases cause a variety of symptoms such as bloating, wind, cramping, diarrhea, burping and constipation. Foods containing fermentable fibre, starch, lactose and fructose can make SIBO symptoms worse, as do gluten, grains, starches like potatoes, legumes and pulses, fruits and some vegetables.
