Researchers believe stress may play a role in a person experiencing IBS due to the connection between the digestive system and the brain, also known as the gut-brain axis.

Doctors believe that emotional factors, such as stress, may play a role in a person developing IBS symptoms. This is largely due to the proposed gut and brain connection.
This article will explore whether stress causes or triggers IBS, the relationship between the gut and the brain, the symptoms of IBS, and other causes of IBS. We will also look at treatment options, how a person can manage stress levels, and when to speak with a doctor.

According to the Canadian Society of Intestinal Research, a person with higher levels of perceived stress is more likely to develop IBS.
What the research says
- changing the composition of the gut microbiota
- impairing the function of the intestinal barrier
- impairing the speed, strength, and coordination of the digestive muscles
- dysfunction of the immune and neuroendocrine systems
The combination of these effects can worsen IBS symptoms and may contribute to the symptoms of pain and bowel movement dysfunction.
The 2020 study also demonstrated that stress could
A recent 2022 study on mice indicated that the mice experienced IBS-like symptoms when subjected to psychological stress without any inflammation or changes to the gut.
Researchers still need to explore this in humans to provide conclusive evidence that the effects are consistent with animal studies.
The gut-brain axis is the term doctors use to describe the
Experts believe that the enteric and central nervous systems can communicate with each other. Due to this link, the brain can influence the activities of the gut and vice versa.
2019 research shows that the brain interacts with the gut through various routes, including:
- nerve connections via the autonomic and central nervous systems
- via cytokines of the immune system
- through hormones via the endocrine system
- through the microbiota, intestinal barrier, and intestinal immune response of the gastrointestinal system
A definitive cause of IBS remains

A person should speak with a doctor if they
- worsening abdominal pain
- unexplained weight loss
- diarrhea during the night

IBS is a group of symptoms that may cause abdominal pain, diarrhea, or constipation. Research shows that stress may trigger or worsen symptoms of IBS due to the brain-gut axis.
A person may manage the symptoms of IBS with medication, mental health therapies, probiotics, and stress management techniques.
A person should consult a doctor if they experience worsening symptoms or additional symptoms such as sudden weight loss or blood in the rectum or stool.
