Abdominal pain
Appendicitis
The appendix is a small, pouch-like sac two to ten centimetres (one to four inches) in length located at the junction of the large and small intestines (right iliac fossa) and shaped like an earthworm. Although its role is still poorly understood, it could be associated with the immune system. Appendicitis, a sudden inflammation of the appendix, is most common and the most frequent medical emergency among young people (6% of individuals aged 10 to 30). It is most often caused by an accumulation of fecal matter, mucus or foreign bodies in the appendix. One of its characteristics is the displacement of pain, which is initially felt near the navel, then extends to the lower-right part of the abdomen. The pain increases over time and is aggravated by pressure on the abdomen when coughing, walking or even breathing. Symptoms of appendicitis include nausea, vomiting, loss of appetite, mild fever, constipation or diarrhea, bloating and a rigid abdomen.
Mechanical intestinal obstruction and paralytic ileus
Ileus can be caused by a mechanical obstruction that prevents the normal transit of contents from the intestine to the rectum. Paralytic ileus can also occur after a complete cessation of contractions (peristalsis) of the digestive tract. In both cases, it leads to a partial or total stoppage in fecal motility, painful distension of the intestine and a probability that the germs it contains will spread to the peritoneum (peritonitis and septicemia). Ileus is an acute condition that is different from simple constipation (i.e. no bowel movement for more than three days). Although constipation is often already present, ileus will usually be accompanied by nausea, vomiting, loss of appetite, swelling of the abdomen and painful abdominal cramps.
Acute cholecystitis
Acute cholecystitis is often a complication involving the presence of stones in the gallbladder. It is manifested as unusual, prolonged (up to several hours) and very intense pain in the upper-right side of the abdomen which spreads to the shoulder and jaw and is accompanied by fever and, often, nausea. Most of the time, a doctor will diagnose cholecystitis by palpating the abdomen under the ribs on the right side. The condition is strongly suspected if the patient experiences pain while inhaling.
Renal colic
Renal colic is a type of intense pain, often described as “excruciating,” most often felt in the lower back, but which can spread to the groin, flank, then abdomen, always on one side of the body. These symptoms are typical of affected kidneys, often due to the presence of stones that move, block the canals and increase the pressure in the kidney and urinary tract. Sometimes, taking analgesics and applying heat (e.g. hot baths) can ease the pain, but it is suggested to go to a hospital emergency room if it becomes intense and is not relieved by oral analgesics, if there is a fever accompanied by other symptoms of a urinary tract infection (e.g. tingling or burning sensation when urinating, blood in the urine, etc.), if you are pregnant or if you have only one functioning kidney[2].
Pancreatitis
The pancreas is an organ located on the upper side of the abdomen, behind the stomach. It plays an essential role in digestion by secreting the enzymes necessary to assimilate food and is also responsible for producing insulin. Its inflammation (pancreatitis) is most often caused by the presence of stones in the biliary ducts which move and block the pancreatic duct that allows digestive enzymes produced by the pancreas to pass through the intestine. This blockage results in the activation of these digestive enzymes within the pancreas itself, causing an engorgement of the gland and intense pain. Alcohol is a frequent cause of acute pancreatitis, which can also occur in individuals already suffering from chronic pancreatitis. The sudden onset of intense pain in the upper abdomen leads to the affected person usually seeking to relieve it by adopting the fetal position. Fever and vomiting are common. In a third of cases, acute pancreatitis will be accompanied by intestinal obstruction (abdomen is swollen, painful and sensitive to the touch). The pain is usually the main factor that justifies a visit to a hospital emergency room. There are several risks of long-term complications associated with chronic pancreatitis: diabetes, infections, kidney failure, digestive disorders, etc.
Ectopic pregnancy and ovarian torsion
Abdominal pain in women is common. Fortunately, most is benign, but some pain can indicate a significant problem that requires either a visit to a hospital emergency room or, at the very least, a consultation with a health care professional. An ectopic pregnancy constitutes an emergency due to the risk of bleeding when the Fallopian tube in which the embryo begins to develop ruptures. It is insidious, particularly when a woman is not aware that she is pregnant. The initial symptoms, such as cramps and mild vaginal bleeding, can occur three to six weeks after fertilization. They can quickly worsen with the onset of severe pain on the side of the affected tube and spread from the tube to the shoulder. A rupture of the tube results in severe abdominal pain and internal bleeding with a drop in blood pressure and, possibly, shock.
Ovarian torsion can also constitute a medical emergency. This relatively rare phenomenon occurs when the ovaries increase in size (e.g. early pregnancy, fertility stimulation, ovarian cyst or tumour). This condition, characterized by sudden and intense pain, is often described as a stabbing sensation in the lower abdomen, usually accompanied by nausea and vomiting. Immediate medical attention is required not only to relieve it, but also to avoid ovarian necrosis. In most cases, the ovary will untwist by itself, but if this does not happen within the first six hours, surgery will be required.
Although they do not normally constitute medical emergencies, gynecological infections, menstrual cramps that prevent women from going about their usual activities, endometriosis, uterine fibroids and ovarian cysts require appropriate medical attention.
Regardless of the situation, when in doubt, do not hesitate to consult a health care professional or call the Info-Santé 811 line.
