Bowel obstructionBowel obstruction, also known as intestinal obstruction, is a mechanical or functional obstruction of the intestines that prevents the normal movement of the products of digestion. Either the small bowel or large bowel may be affected. Signs and symptoms include abdominal pain, vomiting, bloating and not passing gas. Mechanical obstruction is the cause of about 5 to 15% of cases of severe abdominal pain of sudden onset requiring admission to hospital.
Irritable bowel syndromeIrritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by a group of symptoms that commonly include abdominal pain, abdominal bloating, and changes in the consistency of bowel movements. These symptoms may occur over a long time, sometimes for years. IBS can negatively affect quality of life and may result in missed school or work or reduced productivity at work.
DiverticulitisDiverticulitis, also called colonic diverticulitis, is a gastrointestinal disease characterized by inflammation of abnormal pouches—diverticula—that can develop in the wall of the large intestine. Symptoms typically include lower abdominal pain of sudden onset, but the onset may also occur over a few days. There may also be nausea, diarrhea or constipation. Fever or blood in the stool suggests a complication.
Ectopic pregnancyAttachment of an embryo outside the uterusMedical conditionEctopic pregnancy is a complication of pregnancy in which the embryo attaches outside the uterus. This complication has also been referred to as an extrauterine pregnancy (a.k.a. EUP). Signs and symptoms classically include abdominal pain and vaginal bleeding, but fewer than 50 percent of affected women have both of these symptoms. The pain may be described as sharp, dull, or crampy.
AppendicitisAppendicitis is inflammation of the appendix. Symptoms commonly include right lower abdominal pain, nausea, vomiting, fever and decreased appetite. However, approximately 40% of people do not have these typical symptoms. Severe complications of a ruptured appendix include widespread, painful inflammation of the inner lining of the abdominal wall and sepsis. Appendicitis is primarily caused by a blockage of the hollow portion in the appendix.
Abdominal aortic aneurysmAbdominal aortic aneurysm (AAA) is a localized enlargement of the abdominal aorta such that the diameter is greater than 3 cm (1.2 in) or more than 50% larger than normal. An AAA usually causes no symptoms, except during rupture. Occasionally, abdominal, back, or leg pain may occur. Large aneurysms can sometimes be felt by pushing on the abdomen. Rupture may result in pain in the abdomen or back, low blood pressure, or loss of consciousness, and often results in death.
GastroenteritisGastroenteritis, also known as infectious diarrhea, is an inflammation of the gastrointestinal tract including the stomach and intestine. Symptoms may include diarrhea, vomiting, and abdominal pain. Fever, lack of energy, and dehydration may also occur. This typically lasts less than two weeks. Although it is not related to influenza, in Canada and the United States it is often referred to as "stomach flu".
PancreatitisPancreatitis is a condition characterized by inflammation of the pancreas. The pancreas is a large organ behind the stomach that produces digestive enzymes and a number of hormones. There are two main types, acute pancreatitis and chronic pancreatitis. Signs and symptoms of pancreatitis include pain in the upper abdomen, nausea, and vomiting. The pain often goes into the back and is usually severe.
AbdomenAn abdomen (also belly or stomach in vertebrates, or metasoma in arthropods) is the front part of the torso between the thorax (chest) and pelvis in humans and in other vertebrates. The area occupied by the abdomen is called the abdominal cavity. In arthropods, it is the posterior tagma of the body; it follows the thorax or cephalothorax. In humans, the abdomen stretches from the thorax at the thoracic diaphragm to the pelvis at the pelvic brim.Differential diagnosisIn healthcare, a nomothetic (DDx) is a method of analysis that distinguishes a particular disease or condition from others that present with similar clinical features. Differential diagnostic procedures are used by clinicians to diagnose the specific disease in a patient, or, at least, to consider any imminently life-threatening conditions.
PainPain is a distressing bodily feeling often caused by intense or damaging stimuli. The International Association for the Study of Pain defines pain as "an unpleasant sensory and emotionalexperience associated with, or resembling that associated with, actual or potential tissue damage." Pain motivates animals to withdraw from damaging situations, to protect a damaged body part while it heals, and to avoid similar experiences in the future.
Signs and symptomsSigns and symptoms (S/S) are diagnostic indications of an illness, injury, or condition. While signs are objective and externally observable, symptoms are a person's reported subjective experiences. A sign, for example, can be an elevated or lower than normal temperature or blood pressure, or an abnormal finding showing on medical imaging.*As an Amazon Associate I earn from qualifying purchases.
