Overview

The human gut is a bustling ecosystem teeming with trillions of bacteria, most of which reside in the large intestine. But what happens when these bacteria start to invade the small intestine?

The small intestine plays a crucial role in digestion and nutrient absorption. When SIBO or small intestinal bacterial overgrowth occurs, it interferes with these functions. The bacteria may consume nutrients intended for the body, produce gas, and release toxic byproducts, leading to a range of symptoms and complications. The treatment option involves the use of antibiotics along with dietary modifications.

Symptoms of Small Intestinal Bacterial Overgrowth (SIBO)

The symptoms of SIBO can vary from person to person, but they often include:

- Bloating
- Abdominal pain
- Diarrhoea
- Weight loss
- Fatigue
- Nausea
- Vomiting
- Constipation
- Undigested food in the stool
- Gas
- Belching

The symptoms of SIBO can be similar to other digestive conditions, such as irritable bowel syndrome (IBS) and celiac disease. This can make it challenging to diagnose SIBO.

SIBO can also lead to nutrient malabsorption, resulting in vitamin and mineral deficiencies.

Causes of Small Intestinal Bacterial Overgrowth (SIBO)

SIBO can be caused by various reasons, including small intestinal surgery, illnesses that damage the small intestine, and disorders that delay food transit through the digestive tract. Certain drugs, including antibiotics, can potentially induce SIBO.

Below is a list of factors that can contribute to SIBO. It includes -

- Surgery that affects the small intestine
- Diseases that affect the small intestine, such as Crohn's disease or celiac disease
- Conditions that slow down the movement of food through the digestive tract, such as diabetes or scleroderma
- Conditions that increase the number of bacteria in the small intestine, such as pancreatic insufficiency or Zollinger-Ellison syndrome
- Anatomical abnormalities of the small intestine
- Immunocompromised state

Diagnosis of Small Intestinal Bacterial Overgrowth (SIBO)

Diagnosing SIBO can be challenging as its symptoms are similar to other gastrointestinal conditions. However, healthcare professionals and medical advancements have various tests listed below to confirm Small intestinal bacterial overgrowth (SIBO).

- Breath test: This test measures the amount of hydrogen or methane in the breath after drinking a sugar solution. An increase in these gases can indicate SIBO.
- Stool analysis: This test can look for bacteria not typically found in the small intestine.
- Small bowel aspirate: This test involves collecting a fluid sample from the small intestine. The fluid is then analysed for bacteria.

Treatment Options For Small Intestinal Bacterial Overgrowth (SIBO)

The treatment for SIBO depends on the severity of the condition and the underlying cause. In some cases, antibiotics may be prescribed. Other treatment options include:

- Antibiotics: SIBO is often treated with a course of antibiotics. The length of the treatment will depend on the severity of the condition.
- Probiotics: Probiotics are live bacteria that can help restore the bacteria's balance in the gut.
- Digestive enzymes: Digestive enzymes can help to break down food and make it easier to digest.
- Dietary changes: Changing your diet, such as avoiding FODMAPs, can help reduce symptoms.
