Sometimes the problem can extend to the large bowel in a condition called Bile Acid Diarrhoea , where bile acids are not reabsorbed by the small intestine and reach the large bowel, causing diarrhoea. There are many conditions that affect the large bowel.
Inflammatory Bowel Disease IBD is a group of diseases where the bowel appears inflamed and ulcerated. Ulcerative colitis and microscopic colitis , two other types of IBD, are confined to the large bowel. The large bowel can also develop distinct pouches called diverticula, in a common condition called diverticular disease.
Often these pouches do not cause symptoms, or only mild discomfort, but they can occasionally become inflamed or infected, leading to complications, in what is called diverticulitis.
People with IBS experience cramp-like pain and abnormal bowel movements, such as diarrhoea, constipation, or sometimes both alternately. The causes of IBS are not clear though food poisoning or gastroenteritis seem to be common triggers of the condition. The large bowel can also develop polyps , small growths on the wall of the bowel.
Polyps are usually benign but a small number of them can go on to become bowel cancer, which is why bowel screening is so important. There are many other diseases and conditions that affect the gut and the organs associated with it. The liver works hard to support our guts and our digestion but overeating and excess drinking will take their toll on that organ.
People who are overweight or obese can develop non-alcoholic fatty liver disease NAFLD , a condition caused by a build up of fat in the liver. Excessive alcohol drinking can also damage the liver leading to alcohol-related liver disease ARLD. Cirrhosis can cause ascites , a build up of fluid within the abdomen. The abdomen can become so distended that people lose their appetite, become constipated, or feel indigestion, nausea or vomiting.
Cirrhosis can also lead to liver cancer. Our digestive system works hard to keep us well nourished and healthy, working with what we feed it. Its complexity means that there are many places where things can go wrong, which means identifying the cause of some digestive problems can be laborious and time consuming. Looking after our guts and keeping an eye on symptoms and signs can pay off. Skip to content Search Menu Donate.

A common problem for this pyloric valve is for it to be too tight. If this sphincter is too tight or obstructed, it can cause a delay in the stomach emptying as quickly as it should. Basically, the sphincter is a set of muscles around the bottom side of the stomach.
They are meant to control the flow of the food from the stomach and into the intestines. When the sphincter malfunctions dysfunctions and is too loose this can lead to things like diarrhea or dumping syndrome.
Basically speaking the body controls this. When the food has been broken down to a certain level then the pylorus will open a little to allow the food to slowly pass through. There are certain things which can affect this. As an example, if there too much fat in the stomach, then less of the food will be allowed to pass through.
Following a meal, the stomach stores chyme both to begin its digestion and to allow the rest of the digestive system enough time to digest the food thoroughly.
The pyloric sphincter remains closed during eating and while the stomach mixes food with gastric juice to form chyme. After the stomach has completed its digestive role, the pyloric sphincter begins to convulse in waves of peristalsis to push chyme toward the pylorus.
As each peristaltic wave reaches the pylorus, the pyloric sphincter briefly opens to permit a small mass of chyme to pass into the duodenum. Paracentesis is a procedure to remove excess fluid from the abdominal cavity.
This fluid buildup is called ascites. Learn about preparation, recovery…. Learn more. An abdominal film is an X-ray of the abdomen.
