What is Irritable Bowel Syndrome?

Irritable bowel syndrome (IBS) is a condition that affects how the large intestine works. Even though the bowel looks healthy, it doesn’t move or respond the way it should. This can lead to ongoing digestive discomfort and changes in bowel habits.

IBS is a long-term condition, but it does not damage the intestines or lead to more serious diseases like cancer.

The exact cause of IBS isn’t fully understood. However, several factors may play a role:

• Sensitive digestive system that overreacts to normal triggers
• Irregular muscle contractions in the colon
• Certain foods, including high-fat meals or hard-to-digest carbohydrates
• Emotional stress or anxiety
• Hormonal changes, especially in women

IBS is more common in younger adults and tends to affect women more often than men.

Symptoms

IBS symptoms can vary from person to person and may come and go over time. Many people notice that symptoms worsen after eating or during times of stress.

Common symptoms include:

• Abdominal pain or cramping
• Bloating or a feeling of fullness
• Excess gas
• Diarrhea, constipation, or both
• Mucus in the stool

How is it diagnosed?

There isn’t a single test that confirms IBS. Instead, your healthcare provider looks at your symptoms and rules out other possible conditions.

Diagnosis may include:

• A review of your medical history and symptoms
• A physical exam
• Blood or stool tests to check for infection or inflammation
• Imaging tests, such as X-rays or ultrasound, if needed
• Procedures like colonoscopy, in certain cases

The goal is to make sure symptoms aren’t caused by another digestive condition.

How is it treated?

Treatment for IBS focuses on managing symptoms and improving daily comfort. Most people benefit from starting with simple lifestyle changes.

Common treatment options include:

Diet and lifestyle changes

• Increasing fiber intake gradually
• Avoiding foods that trigger symptoms
• Trying a low FODMAP diet
• Eating smaller, balanced meals

Medications

• Treatments for diarrhea or constipation
• Medications to reduce pain or bowel spasms
• Fiber supplements or stool softeners

Other supportive therapies

• Probiotics or peppermint oil for symptom relief
• Stress-reducing activities such as exercise, mindfulness, or counseling

IBS is a lifelong condition, but many people find relief by identifying triggers and following a personalized care plan.
