What is IMO?

IMO (= Intestinal Methanogen Overgrowth) is a microbial overgrowth of the intestine in which methane-producing microorganisms (mostly archaea) can lead to symptoms such as bloating, constipation and abdominal pain.

Microorganisms symbol

Methane-producing archaea

In IMO, certain microorganisms multiply excessively in the intestines. These produce methane, which can slow down intestinal motility – with typical consequences such as constipation.

Nonspecific symptoms symbol

Nonspecific complaints

Bloating, a distended abdomen, constipation and abdominal pain are common symptoms – however, they can have many causes, which is why IMO is often overlooked.

SIBO symbol distinction

Difference to SIBO

IMO is now distinguished from SIBO (small intestinal bacterial overgrowth) because different microorganisms are involved and the symptoms can vary.

What are the harmful consequences?

An imbalanced gut flora can impair nutrient absorption, potentially leading to vitamin, nutrient, or protein deficiencies, among other things.

Deficiency symptoms symbol

Nutrient deficiencies

An imbalanced gut flora can impair the absorption of important vitamins and minerals – with possible effects on energy, immune system and well-being.

Chronic ailments symbol

Chronic conditions

If left untreated, the symptoms can persist and permanently impair quality of life – therefore, early detection is important.

Protein deficiency symbol

Protein deficiency

Protein utilization may also be impaired, which can affect muscle strength, regeneration, and general vitality.

Unknown cause symbol

Often overlooked cause

Because the symptoms are nonspecific, IMO is often not recognized – a targeted test can provide clarity here.

What can you do?

The new IMO breath test can detect bacterial overgrowth. Your breath samples are analyzed in the laboratory. The methane and CO₂ levels in your exhaled air can provide indications of methane-related bacterial overgrowth – simply, safely, and without a doctor's visit.
