SIBO symptoms?

You cannot fit into your jeans anymore because you feel so bloated? You wake up with a flat belly in the morning, and in the evening, you look like six months pregnant? These may sound a bit extreme, but they are not exceptional cases. Many clients experience constant gas or bloating, and some of them already have the popular diagnosis of IBS.

I want to emphasize that bloating is not normal, especially when it happens constantly. It is always a sign of gut inflammation and irritation and is one of the leading SIBO symptoms.

What is SIBO?

SIBO stands for Small Intestinal Bacterial Overgrowth. It means an increase in the number of bacteria and/or changes in the types of bacteria present in the small intestine. SIBO symptoms and SIBO are commonly caused by an overgrowth of various bacteria that should generally be found in the large intestine. (1)

Classic SIBO symptoms are similar to IBS symptoms (Irritable Bowel Syndrome). These include abdominal pain, discomfort, cramping, gas, bloating, reflux, diarrhea, and/or constipation.

According to studies, 84 % of IBS cases are caused by SIBO. (2)

 

10 typical SIBO symptoms:

  1. You have constant bloating and gas – you may have difficulty figuring out which foods cause flatulence because you are bloated all the time, or bloating just increases as the day goes on.
  2. You have persistent diarrhea or constipation – hydrogen-dominant SIBO usually causes diarrhea, while "methane-dominant SIBO" (or precisely IMO- Intestinal Methanogen Overgrowth) mostly causes constipation, but this is also not always true! Mixed types are also common. (3)
  3. Your symptoms get worse when you eat fiber – You may have heard that the daily value for fiber is around 25 grams per day on a 2,000-calorie diet for adults (4). You still try to complete this challenge, but your symptoms have gotten worse. In that case, SIBO can be the culprit. Typically, a healthy gut needs fiber to feed the good bacteria and support normal function. However, your symptoms get worse if you feed the overpopulated bacteria. 
  4. You have several food intolerances, such as gluten, lactose, fructose, and histamine intolerance. – You lack enzymes, which are needed to break down certain foods, triggering a digestive response. (5)(6)
  5. You are already diagnosed with IBS – the majority of IBS patients have SIBO symptoms – you should not be satisfied with the IBS diagnosis; dig deeper!
  6. You feel worse after eating – You get full quickly after eating a normal-sized meal, which can happen when you have low stomach acid. (7) Slow stomach emptying when the food stays in your stomach for long hours, causing nausea, can contribute to SIBO. Damage to the migrating motor complex (MMC), which is usually responsible for sweeping food and bacteria through the digestive tract and gets activated when you don’t eat, is one of the most common underlying causes of SIBO. (8)
  7. You don’t do well with probiotics—do you get abdominal pain and cramping after eating fermented foods such as kefir, sauerkraut, and kimchi? Maybe you tried random multi-strain probiotics that just made everything worse. These could also be a sign of SIBO. 
  8. You have chronic illnesses such as chronic fatigue syndrome and autoimmune diseases - Leaky gut can also be a culprit if your gut remains “leaky,” and food particles, among others, can get into your bloodstream. These will activate your immune system, which will begin attacking foreign invaders, triggering inflammation. A long-term defense can lead to damage to your organs and food intolerances, as these foreign invaders may look similar to your own body’s cells, and the immune system gets confused, overloaded, and starts attacking your tissues. (9)
  9. You suffer from skin rashes and rosacea – an impaired gut (SIBO symptoms) can also cause skin problems.
  10. You have malabsorption issues, such as fat (which can also cause floating stools) and/or vitamin and mineral deficiencies, especially fat-soluble vitamins (D, E, K, A).
