If left untreated, IBS doesn't cause permanent bowel damage but significantly lowers your quality of life, leading to chronic pain, bloating, anxiety, depression, social isolation, and missed workdays, while potentially causing related issues like hemorrhoids, anal fissures, and nutritional deficiencies due to avoidance of foods. Untreated IBS creates a vicious cycle where stress worsens symptoms, and symptoms increase stress, impacting overall physical and mental health.
More-serious symptoms include:
IBS poop varies greatly, often fluctuating between hard, lumpy, and difficult-to-pass stools (IBS-C) and loose, watery, and urgent stools (IBS-D), or alternating between both (IBS-M), sometimes with mucus present, but not blood. Shapes can range from small pellets to thin, pencil-like forms, and color might shift due to speed of passage (e.g., green/yellow for fast, darker for slow).
IBS doesn't cause tissue damage in your GI (gastrointestinal) tract or increase your risk of more serious conditions, like colon cancer. Instead, it's a chronic (long-term) condition that most people can manage by changing their routines and what they eat, taking medications and receiving behavioral therapy.

stomach pain or cramps – usually worse after eating and better after doing a poo. bloating – your tummy may feel uncomfortably full and swollen. diarrhoea – you may have watery poo and sometimes need to poo suddenly. constipation – you may strain when pooing and feel like you cannot empty your bowels fully.
Irritable bowel syndrome (IBS) is a common disorder of gut–brain interaction (DGBI)1 in which individuals experience recurrent symptoms of abdominal pain, altered bowel habits and often bloating. Medical management of IBS has historically focused on treating the most bothersome of these gastrointestinal symptoms.
Conditions whose symptoms may be mistaken for IBS include: Celiac disease: While celiac disease may cause constipation, diarrhea, pain and bloating, it often also has symptoms unrelated to digestion, such as fatigue, joint pain or a rash.
See your GP urgently if: You have other symptoms, including: a change in your bowel habits that has lasted for more than 6 weeks, especially if you are over 50 years of age. unexplained weight loss.
It has since been found that 82% of IBS sufferers are also low in vitamin D (less than 20 ng/mL)2 so naturally we come to question if there is a link between vitamin D and IBS symptoms. The University of Sheffield has been spearheading this important area of research.
7 Common Symptoms of Irritable Bowel Syndrome (IBS)
For IBS sufferers: Yellow stools can sometimes be associated with IBS, especially if you have the type of IBS that involves frequent diarrhoea. It can also occur if there are issues with fat digestion. If you experience yellow stool along with stomach cramps or bloating, it might be time to talk to your doctor.
The worst foods for IBS are often high in FODMAPs (fermentable carbs) like onions, garlic, wheat, and apples; dairy; fatty/fried foods; caffeine; alcohol; and artificial sweeteners, as they trigger gas, bloating, pain, and diarrhea, but triggers vary, making a low-FODMAP diet or food diary crucial for identifying personal culprits.
While IBS does not cause damage to your intestines or lead to serious disease – like cancer – it's important that you reach out to a trusted provider with any recurring symptoms that are painful or cause you anxiety.
Medicines specifically for IBS
Your doctor may diagnose IBS if you have pain in your abdomen along with two or more of the following symptoms:
Common flare-up symptoms include abdominal pain, bloating, gas, diarrhea, and constipation. The severity and duration of these flare-ups can vary from person to person and can be triggered by certain foods, stress, hormonal changes, or other environmental factors.
When you ignore IBS, it can wreak havoc on your life. Unmanaged IBS can contribute to frequent and sudden changes in your bowel habits, which can be frustrating and embarrassing whether you're at home or at work.
IBS is a chronic gastrointestinal condition that can cause abdominal pain, cramping, bloating, gas, and changes in bowel habits—including diarrhea, constipation, or both. Though it doesn't damage the digestive tract, it can interfere with daily routines, diet, and emotional well-being.
Symptoms of IBS
IBS symptoms and their intensity can vary from person to person. Symptoms often occur after eating a large meal or when you are under stress, and they are often temporarily relieved by having a bowel movement. Anemia, bleeding, weight loss, and fever are symptoms of IBD, not IBS.
Both IBS and colon cancer can result in diarrhea, constipation or an alternating pattern of both. Persistent pain or cramping in the abdomen is common to both conditions. Gas and bloating are shared symptoms that may cause a feeling of fullness.

Irritable Bowel Syndrome and the Brain
If you have IBS, the nerves in your gut are extremely sensitive, and the brain processes these signals from your gut differently than it would if you did not have IBS. Even small amounts of gas can trigger pain, bloating, constipation or diarrhea.
For some people a gut infection or antibiotic use can cause the condition to start. There is a tendency for IBS to run in families, but no gene for IBS has been found. But it's hard to separate genetics and the family environment. Changes in the microbes normally found in the gut have been linked to IBS.
IBS pain can feel like cramping, bloating, pressure, or sharp stabbing sensations. It may worsen after eating, during stress, or around hormonal changes such as menstruation.
