Recognize irritable bowel syndrome
Irritable bowel syndrome (IBS), is a disorder of the functioning of the intestine (colon or large intestine), not serious but responsible for significant discomfort.
WHAT IS IRRITABLE GUT SYNDROME?
Irritable Bowel Syndrome (IBS) also known as Irritable Bowel Syndrome (IBS) is a combination of disorders in the functioning of the bowel including:
- abdominal pain
- discomfort,
- intestinal transit disorders (constipation, diarrhea or alternation of the two).
We also speak of functional colopathy.
It is a frequent disease which affects around 5% of the French population. It is not serious, but because of its chronicity, it affects the quality of life of people who suffer from it.
The diagnosis is usually made between the ages of 30 and 40. More rarely, this syndrome can appear in children and adolescents.
Women are twice as affected as men by bowel syndrome or irritable bowel syndrome.
MECHANISMS OF IRRITABLE INTESTINE SYNDROME
The mechanisms of occurrence of irritable bowel syndrome are poorly understood and multiple, but we observe in this disease:
- a bowel movement disorder: the contractions of the small intestine and colon may be either too strong or too weak. Food then moves too quickly or too slowly, causing diarrhea or constipation;
- abnormalities of intestinal sensitivity: People with functional colopathy have more sensitive intestines. They feel more painfully normal phenomena, such as bloating, gas, abdominal pain;
- intestinal micro-inflammation and abnormalities of the digestive bacterial flora (or microbiota) which can increase the production of digestive gases;
- an increase in disorders after food intake or in connection with what is consumed.

FACTORS PROMOTING IRRITABLE INTESTINE SYNDROME
Symptoms of irritable bowel syndrome can be triggered or favored by fatigue or stressful situations (daily changes, travel, etc.).
Gastroenteritis can trigger irritable bowel syndrome.
Psychological factors such as anxiety, anxiety, or unbalanced or overly large meals can also amplify symptoms.
Conversely, during rest or vacation periods, the symptoms tend to decrease.
Digestion is a long process
After a first partial digestion in the stomach, the food arrives in the small intestine. During this progression, the body absorbs most of the nutrients it needs. The residues of the digested food then pass into the colon to constitute the stool. The small intestine and colon move food forward by contracting.
During digestion, the breakdown of food by the intestinal flora (microbiota) leads to natural fermentation and the production of gas.
SYMPTOMS OF IRRITABLE INTESTINE SYNDROME
The most common symptoms are of three types:
Abdominal pain
Stomach pain is the most common symptom in irritable bowel syndrome. Abdominal pain is a feeling of spasm or cramp and is usually in the right and left iliac fossa or in the umbilicus region.
It usually occurs after a meal but can also appear upon awakening. It can last from a few hours to a few days. It is conventionally relieved by the emission of stool or gas.
Abdominal pain is usually absent at night.
Abdominal bloating
Abdominal bloating is also common and is a discomfort that makes it difficult to wear tight clothes, especially after meals. At most, it is a permanent abdominal tension that is difficult to bear, with distension of the belly.
The bloating may be accompanied by noises inside the digestive tract due to the movement of gases and liquids (rumbling). Like pain, bloating (or gas) may be improved by the emission of gas or stool.
Intestinal transit disorders: constipation and / or diarrhea
They are most often manifested by constipation. However, diarrhea is possible characterized by the emission of several watery stools during the day, often in the morning or after a meal.
Alternating diarrhea and constipation may also appear.
Thus, depending on the prediminating transit disorder observed, different forms of irritable bowel syndrome are defined:
- with predominant diarrhea (IBS-D),
- with predominant constipation (IBS-C),
- with alternating diarrhea-constipation or mixed form (SII-M).
Irritable bowel syndrome: symptoms that come back often and last
To be able to speak of irritable bowel syndrome, the symptoms must be present at least 1 day per week over the last 3 months and fall within a period of at least 6 months.
HOW IS IRRITABLE COLON SYNDROME EVOLVING?
In most cases, symptoms of functional colopathy persist, with periods of crisis and improvement, or even lull.
Diseases are more commonly associated with irritable bowel syndrome:
- headaches,
- fibromyalgia,
- interstitial cystitis or painful bladder syndrome,
- chronic fatigue syndrome,
- other digestive disorders such as dyspepsia (difficulty digesting), gastroesophageal reflux ...
Irritable bowel syndrome does not increase the risk of developing colon cancer or chronic inflammatory bowel disease (Crohn's disease, ulcerative colitis).
It does not require surgery and does not decrease your life expectancy.
