Irritable bowel syndrome (IBS) is a common disorder of the large intestine resulting in cramping, bloating, abdominal pain, mucus in the colon, gas, and diarrhea or constipation or even both. It reportedly affects at least 6-18% of people worldwide, according to Healthline, but that may not include millions of undiagnosed patients. IBS is tricky to diagnose because its symptoms can be similar to food sensitivities and other irritable bowel diseases. Though it is a chronic disorder, it can be controlled by managing diet, lifestyle, and stress. Here are the telltale signs you could have IBS.Pain occurs in your abdomen.Pain will generally be found in the lower abdomen, where your large intestine resides, or in the entire abdomen. Pain will typically subside after a bowel movement.

Abdominal pain that occurs with both constipation and diarrhea is a key figure in determining if you're suffering from IBS as opposed to food or colon issues.

Many women also cite increased symptoms either just before or during their period. See the rest of the story at Business Insider Click here to read full news..
