Causes of Irritable Bowel Syndrome (IBS)

Causes of Irritable Bowel Syndrome (IBS)

Genetic Factors

Irritable Bowel Syndrome (IBS) might have a genetic predisposition. Research suggests that individuals with family members suffering from IBS might be more susceptible to developing the condition themselves. This implies a potential hereditary link, although the exact genetic markers remain under investigation.

Dietary Influences

The diet of individuals in the United Kingdom has been linked to the onset of IBS. High-fat foods, spicy meals, alcohol, and caffeinated beverages can trigger IBS symptoms in susceptible individuals. Additionally, artificial sweeteners and certain fibers found in processed foods might aggravate the bowel.

Gut-Brain Interaction

There is increasing evidence that IBS is linked to problems with the interaction between the brain and the gut. Stress and anxiety can exacerbate IBS symptoms, as the gut is sensitive to mental health. Psychological factors may alter gastrointestinal function, leading to discomfort and irregular bowel movements.

Gastrointestinal Infections

Post-infectious IBS occurs when individuals develop the condition following a bout of acute gastroenteritis. The inflammation from the infection can lead to changes in the gut's normal functioning, resulting in chronic symptoms of IBS even after the infection has cleared.

Intestinal Flora Imbalance

An imbalance in the gut microbiota, the community of microbes living in the intestines, can contribute to IBS. A reduction in beneficial bacteria or an overgrowth of harmful bacteria can disrupt normal bowel function and cause IBS symptoms. Probiotic treatments may help restore balance in some cases.

Food Intolerances

Food intolerances, particularly to lactose, gluten, and certain fermentable carbohydrates (FODMAPs), are commonly linked to IBS. The inability to properly digest these substances can lead to bloating, gas, and bowel irregularities, which are characteristic symptoms of IBS.

Hormonal Changes

Hormonal fluctuations, particularly in women, can influence IBS symptoms. Many women report worsening symptoms during their menstrual cycles, suggesting that hormonal changes play a role in the severity and frequency of IBS episodes.

Family Connections

Some people might get Irritable Bowel Syndrome (IBS) because of their family. If your family members have IBS, you might get it too. This means it could run in families.

What We Eat

What we eat can make IBS worse. In the UK, foods high in fat, spicy foods, drinks with alcohol, and drinks with caffeine can cause problems. Sweeteners and some fibers in packaged foods can also upset the stomach.

Stomach and Brain Connection

IBS can happen because of the way the brain talks to the stomach. Stress and worry can make IBS worse. Our feelings can change how our stomach works, causing pain and bathroom problems.

Stomach Infections

Sometimes, after a stomach infection, people can get IBS. The infection can change how the stomach works, making IBS last even after you're better from the infection.

Good and Bad Germs

Our stomachs have good germs that help us stay healthy. If these germs get out of balance, it can cause IBS. Taking probiotics might help by adding more good germs back to the stomach.

Food Problems

Some people can't eat certain foods like milk (lactose) or bread (gluten). These foods can cause IBS symptoms like a swollen tummy, gas, and bathroom issues.

Hormones

Hormones are chemicals in our bodies. They can change a lot, especially in women. Many women say their IBS gets worse during their period. This shows hormones can make IBS worse.
