Abdominal pain occurs as a result of a broad range of conditions but can be divided into two main categories: acute abdominal pain, which comes on very suddenly and is severe in intensity, and chronic (long-term) abdominal pain, which is less severe but persistent, though it may come and go.
The most common causes of acute abdominal pain that require surgery include appendicitis, blockage of the bowel, inflammation of the gallbladder, gallstones getting stuck in a bile duct and kidney stones.
Chronic abdominal pain can also be caused by gallstones as well as gastroenteritis and inflammation of the bowel. In women, the pain may be caused by problems with the reproductive organs, such as ovarian cysts or endometriosis.
Depending on the underlying cause of your abdominal pain, you may also experience a change in your bowel habits, loss of appetite, nausea and vomiting. You may notice rectal bleeding, weight loss and/or fatigue.
If your abdominal pain is caused by a problem with your urinary system, you may have difficulty passing urine or notice blood in your urine.
In women, if the cause of your abdominal pain originates in your reproductive organs, you may notice unusual vaginal discharge and a change in your menstrual cycle.
If you are worried about your abdominal pain or you have chronic abdominal pain that is worsening or not improving, see your GP.
It is also important to see your GP if, alongside your abdominal pain, you also notice a sustained change in your bowel habits (eg diarrhoea or constipation), rectal bleeding or unintentional weight loss.
