Irritable bowel syndrome (IBS): IBS is also known as irritable colon, spastic colon, spastic colitis, and mucous colitis. It is a common disease that affects the large intestine. An irritable bowel syndrome is a group of intestinal symptoms that occur together. The exact cause is unknown, but common causes of IBS are acidity, stress, carbonated foods and beverages, irregular hormone levels, and certain foods and medications. Symptoms include abdominal pain, cramps, bloating, gas, constipation, and/or diarrhoea.
Ulcerative colitis: It is a type of chronic inflammatory bowel disease that causes inflammation of the lining of the large intestine (colon) and produces ulcers on the lining of the colon, which may cause bleeding and discharge of pus and mucus. The common symptoms include bloody stools, stomach pain, rectal pain, diarrhoea, fever, and weight loss. Additionally, it may cause other problems such as joint pain or swelling, mouth sores, skin problems, decreased appetite or nausea.
