What Is an IBS Flare-Up?

An IBS flare-up is a period when the symptoms of Irritable Bowel Syndrome (IBS) become worse than usual. IBS is a long-term condition that affects the digestive system and commonly causes abdominal pain, bloating, diarrhoea, constipation, or a combination of both.

Flare-ups can be triggered by a variety of factors, including stress, certain foods, hormonal changes, lack of sleep, or changes to your routine. Symptoms can vary from person to person and may last for a few days or several weeks.

Although IBS can significantly affect quality of life, it does not damage the bowel or increase the risk of bowel cancer.

📅

Typical Sick Leave Duration

1-3 days depending on severity. Our doctor will assess your situation and recommend appropriate time off.

Is an IBS Flare-Up a Valid Reason for a Sick Note?

Yes, an IBS flare-up can be a valid reason for a sick note if symptoms are severe enough to affect your ability to work or carry out your usual duties.

Frequent diarrhoea, abdominal pain, bloating, fatigue, and urgent trips to the toilet can make it difficult to work effectively, attend meetings, travel, or perform physically demanding tasks.

Frequently Asked Questions

What Triggers an IBS Flare-Up?

Common triggers include stress, anxiety, certain foods, caffeine, alcohol, hormonal changes, poor sleep, and changes in routine. Triggers can vary from person to person.

How Long Does an IBS Flare-Up Last?

An IBS flare-up may last anywhere from a few days to several weeks. The duration often depends on the trigger and how well symptoms are managed.

Can Stress Cause an IBS Flare-Up?

Yes. Stress and anxiety are common triggers for IBS symptoms because the digestive system and brain are closely connected. Many people notice that symptoms worsen during stressful periods.

Can IBS Cause Diarrhoea and Constipation?

Yes. Some people experience predominantly diarrhoea, others mainly constipation, and some alternate between the two.

Is IBS the Same as Inflammatory Bowel Disease?

No. IBS is a functional digestive disorder, whereas inflammatory bowel disease (IBD), such as Crohn’s disease or ulcerative colitis, causes inflammation and damage to the digestive tract.
