What are SIBO Symptoms?

SIBO affects the gut. The following symptoms may occur:


SIBO is not yet fully understood. It can occur in these situations:

  • congenital diseases of the small intestine (anatomical anomalies)
  • pH change in the small intestine
  • a disorder in the immune system
  • muscle disorder in the small intestine

SIBO is associated with a variety of conditions such as:

Risk factors

A disease or surgery that affects the digestive system can increase the risk of SIBO. For example:

  • Crohn's disease
  • diabetes
  • scleroderma
  • HIV (AIDS)
  • Parkinson's disease
  • hypothyroidism
  • drugs that slow the gut, such as narcotics


If you have symptoms of SIBO, it is useful to see a doctor. Diagnosis can be made with anamnesis, examination and some tests.

Breath test

It is a common test. It can be done at home or in the clinic. Excess bacteria in the small intestine release hydrogen and methane gas. This can be detected through breathing. The test is done on an empty stomach.

During the test, you will breathe into a tube. Then you will have a special sweet drink. Then, blowing samples will be taken at regular intervals for 2-3 hours.

Other tests

If breath test results are questionable, a fluid sample can be taken from the small intestine to detect bacteria.

SIBO Treatment

SIBO can be treated with antibiotics and diet.


Bacteria must be taken under control first. This is usually ciprofloxacin (Cipro)metronidazole (Flagil) or rifaximin (Hepazec, Colidur) It is made with antibiotics such as. If there is a malnutrition, serum insertion may be required.

Antibiotics can reduce the number of bacteria in the small intestine. However, this alone does not solve your question. The underlying cause of SIBO must be found and treated. Dietary changes can help with this.

Diet and SIBO

Many patients can relax with a personalized diet. There is no special diet for SIBO, you may only need to make small adjustments:

  • Eat balanced and nutritious foods.
  • Increase the number of meals and reduce the amount (less, less often).
  • Your celiac disease avoid gluten products if available.
  • Your doctor may also suggest that you try a basic diet. This diet replaces foods and drinks with certain liquid formulas for a specified period of time. In a small-scale study, “Trusted Source”, 80 percent of participants with SIBO had a normal breath test result after following a basic diet for 15 days. Researchers concluded that a basic diet can be highly effective in managing this condition. However, more research is needed. Before starting this diet, work with your doctor and follow his instructions.

Can probiotics be used to treat SIBO?

Probiotics It can bring the bacteria count in the gut back to normal. A 2010 study found that probiotics may be more effective than antibiotics in treating SIBO. However, a review from 2016 found that evidence that probiotics are effective in treating SIBO is insufficient. The best option is to follow your doctor's advice.


SIBO is caused by an underlying condition. If you have a chronic condition such as Crohn's disease or celiac disease, work with your doctor to develop a long-term treatment plan. SIBO can be treated, but it can recur. It can also lead to malnutrition if left untreated.
