Left abdominal pain is often not only quite severe, but in some cases can be quite frightening. Appendicitis is one of the most common causes of left abdominal pain. Other common causes include the development of an ectopic pregnancy or even a kidney infection. In other cases, those suffering from abdominal pain may be diagnosed with an inguinal hernia. When left untreated, these conditions can be quite serious. Therefore, anyone who experiences severe left abdominal pain should seek medical help immediately in order to avoid complications.

One of the most common causes of left abdominal pain is appendicitis. Appendicitis occurs when the appendix becomes inflamed and enlarged. Typically, pain associated with appendicitis begins near the belly button, and radiates towards the left side of the abdomen. Appendicitis often starts with relatively minor symptoms and increases in severity over the course of the day. When left untreated, an infected appendix can burst, leading to dangerous complications.

In women, an ectopic pregnancy is a common cause for left abdominal pain. An ectopic pregnancy is diagnosed when an egg is fertilized in the fallopian tubes. Typically, an ectopic pregnancy will not be viable, and the loss of the fertilized egg leads to high amounts of left abdominal pain, as well as pelvic cramping and vaginal bleeding. While the cause of ectopic pregnancies is not well understood, many believe that it may be caused by damage to other parts of the female reproductive system. Often, this type of damage occurs commonly in women who have suffered from an untreated sexually transmitted disease in the past.

A kidney infection is another common cause of left abdominal pain. This kind of infection typically occur as a result of an untreated urinary tract infection. Though a kidney infection may seem relatively minor, when left untreated, it can be life-threatening. Those who experience pain during urination or an increased need to urinate along with their left abdominal pain should seek medical assistance immediately.

In some cases, an inguinal hernia may be the cause of left abdominal pain. Inguinal hernias often develop when individuals lift, push, or pull very heavy items, placing an excessive amount of stress on the abdominal cavity. This condition is diagnosed when a portion of the intestine forces its way through a lower abdominal wall tear. An inguinal hernia is often quite painful, and features a large bulge that is most evident during coughing or bending. In most cases, surgery is required to completely remove an inguinal hernia.
