Irritable Bowel Syndrome – Symptoms, Diagnosis, and Causes of Chronic Ailment

Gastroenterologists agree that disorders linked to functional disturbances of the digestive system are the most commonly diagnosed conditions. Irritable bowel syndrome (also referred to as IBS-Irritable Bowel Syndrome) is a chronic digestive tract disorder that lasts for at least three months. It is primarily marked by severe abdominal pain and disruptions in bowel movements. Numerous individuals, despite experiencing distressing symptoms such as diarrhea, constipation, bloating, and abdominal pain, do not pursue medical consultation.

Irritable bowel syndrome manifests through a range of symptoms, including abdominal pain with varying intensity and location. These discomforts arise from the accumulation of small amounts of gas and food residues in the digestive tract, leading to bloating and pain in the pelvic region. Additionally, patients experience irregular bowel movements, which may alternate between diarrhea and constipation, with defecation often providing relief. They frequently report post-meal heaviness, nausea, heartburn, fatigue, frequent urination, and in women, menstrual irregularities. Due to the nonspecific nature of these symptoms, they are often incorrectly attributed to poor diet, whereas they may represent early indicators of irritable bowel syndrome.

When the described symptoms persist for at least three months, the physician may establish a diagnosis of irritable bowel syndrome after a thorough clinical interview with the patient and precise inquiries regarding the symptoms and their resolution (e.g., after bowel movement). To exclude organic causes of the ailments, the doctor typically opts for comprehensive laboratory testing to confirm the diagnosis. It is recommended to conduct a complete blood count, urinalysis, and stool analysis (bacteriological and parasitological tests). Depending on the patient's age, accompanying symptoms, and suspicion of other causes of the ailments, the physician may decide to perform a colonoscopy, although this is not mandatory. Additionally, it may be necessary to confirm the diagnosis using ultrasonography or radiological examinations, as well as performing a lactose tolerance test or adhering to a lactose-free diet for a specified period to rule out lactose intolerance.

Recurrent episodes of diarrhea and constipation may suggest the presence of irritable bowel disorder. These conditions arise from disturbances in intestinal motility, when the muscular contractions that facilitate the movement of food through the intestines to the rectum are impaired. Motor dysfunction of the intestines may be closely linked to the neural centers in the brain that regulate this process. Mechanical irritation of the intestinal walls can lead to pain and discomfort in the abdominal area. This condition can be exacerbated by stress, unhealthy eating habits, and consuming meals in haste. Unfortunately, there is no single, definitive cause for this condition, as its development results from the interplay of individual, genetic, and environmental factors. Irritable bowel disorder is a troublesome digestive tract condition characterized by abdominal pain and alternating episodes of diarrhea and constipation. Non-specific symptoms often do not prompt patients to seek medical attention for diagnosis and treatment. However, if symptoms persist for more than three months, it is advisable to consult a physician to determine the underlying cause.
