![]() The severity of the disease depends on multiple genetic abnormalities and the effect of microbes on your immune system. These conditions are genetic for many patients, but no single gene is known to be the cause. ![]() The most common conditions are ulcerative colitis and Crohn's disease. Inflammatory bowel disease (IBD) is a term that represents several gastrointestinal conditions that cause swelling and inflammation of the intestines. Your stool may be loose and watery on some days or hard and lumpy on others. IBS-M – Alternating symptoms of constipation and diarrhea. IBS-D – Diarrhea is the main symptom, characterized by frequent bowel movements and over a quarter of the stools you pass being loose. IBS-C – Constipation is the main symptom, resulting in fewer bowel movements, and you will likely strain when passing them. There are different types of IBS, categorized according to their symptoms: If you have IBS, you may experience diarrhea or constipation – sometimes, you might even have both. These episodes can be triggered by certain foods, such as dairy products or caffeinated beverages, or they can occur during periods of high stress.Īlthough both IBS and IBD can have a significant impact on quality of life without treatment or lifestyle changes, IBD often requires more aggressive treatment in order to minimize the risk of complications and damage to the digestive tract-so it’s important to get an accurate diagnosis and seek treatment.Irritable bowel syndrome (IBS) is a disorder that affects the lower gastrointestinal area, including the colon, large intestine, and small intestine. IBS can affect patients in a few different ways: Doctors may diagnose a patient as diarrhea-predominant (IBS-D), constipation-predominant (IBS-C), or have alternating episodes of diarrhea or constipation (IBS-M, as in “mixed”). Here are more signs your stomach pain is actually IBS. However, IBS is not associated with bloody stool (unlike IBD), and IBS pain tends to be relieved (or at least lessened) after a bowel movement. There is some overlap between symptoms of IBS and IBD: Both are known to cause abdominal pain and diarrhea, for example. ![]() While syndromes cause real symptoms that can affect quality of life, they may not cause visible damage that appears on imaging tests or lab work. The word syndrome generally refers to a cluster of related symptoms with an unknown cause. Ulcerative colitis, on the other hand, “is continuous inflammation beginning in the rectum and extending upwards, and only occurring in the colon,” says Dr. “It can occur in skip fashion, so you can have one area of bowel that's affected, then another normal area, and then another area that's affected.” That said, Crohn’s disease most commonly affects the small intestine, according to the National Institute of Diabetes and Digestive and Kidney Diseases. “Crohn's disease can occur anywhere from the mouth to the anus,” says Dr. The continuous attacks lead to chronic inflammation and damage, and cause symptoms like diarrhea, abdominal pain, and rectal bleeding. “Inflammatory bowel disease is generally thought of as Crohn's disease and ulcerative colitis,” says Benjamin Cohen, MD, gastroenterologist at The Mount Sinai Hospital in New York City.īoth Crohn’s disease and ulcerative colitis occur when the immune system-which is supposed to attack foreign pathogens to protect the body from illness-attacks the digestive tract instead. In fact, despite their symptoms, their digestive tract would look perfectly fine. The biggest difference between the two? IBD causes visible damage to the digestive tract due to chronic inflammation, whereas a colonoscopy of a patient with IBS would show *no* inflammatory damage.
