Irritable bowel syndrome (IBS) is a common disorder of the intestines.\nCommon IBS symptoms include:\n\nCramping\nStomach pain\nGas\nBloating\nChanges in bowel habits\n\nSome people with IBS have constipation (infrequent bowel movements). Others have diarrhea (frequent, loose stools). Some people have both.\nEating more or less fiber can help control these problems.\nTips to Increase Fiber in Your Diet and Help Constipation\nIf you have constipation, a high-fiber diet can help. Foods high in soluble fibers \u2014 like oats, peas, and beans \u2014 can help ease both constipation and diarrhea.\nAdd fiber a little at a time\n\nTry to eat 20 to 35 grams of fiber each day. Use food labels to tell how many grams of fiber are in foods you eat.\nAdd more fiber to your diet a little at a time. Adding too much fiber too quickly may trigger other IBS symptoms. Be sure to increase your fluid intake at the same time.\nPut more fiber in meat dishes by adding beans, bran, or oatmeal.\nAsk your doctor if a multi-vitamin and mineral supplement with 100 percent of the U.S. recommended daily fiber intake (RDI) may be helpful.\n\nRELATED:\u00a0Understanding Indigestion: Causes, Symptoms, and Treatment\nWatch for foods that cause your IBS symptoms\n\nPay attention to when your symptoms occur.
