SIBO SymptomsSIBO Symptoms-What Do Sufferers Feel?

SIBO-IBS is a disease that affects the gastrointestinal tract. The main symptoms of SIBO overlap with Irritable Bowel Syndrome. Studies have shown that SIBO exists in 84% of patients who get an IBS diagnosis and therefore we know that it is a contributing factor to the disease. SIBO is also associated with many other disorders as a secondary effect of a pre-existing disease or an underlying cause.

It is important to remember that people who have SIBO usually experience pretty severe gastrointestinal symptoms to the point where they have a big impact on their quality of life. They are not the occasional episodes of gas or diarrhea. When someone has SIBO symptoms they are usually chronic and very noticeable to the point where there is suffering and social isolation for prolonged periods of time.

Below are the following symptoms associated with SIBO:


  • Bloating
  • Gas
  • Belching/Flatulence
  • Cramps
  • Abdominal Pain
  • Constipation
  • Diarrhea
  • Alternating constipation and diarrhea
  • Heartburn
  • Nausea
  • Fatigue
  • Food sensitivities
  • Skin symptoms
  • Respiratory symptoms (like asthma)
  • Depression
  • Autism
  • Steatorrhea (fatty stools)
  • Anemia
  • Weight loss or gain
  • Incomplete bowel movements
  • Brain symptoms
  • Indigestion
  • Slow movement of digestion
  • Restless legs
  • Urgent bowel movements

If you have severe gastrointestinal symptoms that seem like the typical Irritable Bowel symptoms or if you have symptoms of a disease that is associated with SIBO and are experiencing digestive symptoms as well, consider SIBO.

I would say personally that the most noticeable symptoms associated with SIBO in my experience are excessive bloating, gas, and dramatically altered bowel movements where the symptoms are unbearable and make it hard to be around people or attend events. If you are experiencing these symptoms educate yourself about breath testing options, how to treat it, and seek medical help from an expert.
