Causes of Abdominal Pain and Fatigue
Abdominal pain and fatigue often indicate a systemic illness.

Abdominal pain is a common symptom that usually occurs as a result of the accumulation of excess gas in the abdomen. Most abdominal pain is acute, meaning it comes on suddenly and does not last for an extended period of time. When abdominal pain occurs in conjunction with fatigue, it can indicate an underlying infection or medical condition that affects the entire body.

Food Poisoning

Food poisoning, or food-borne illness, is a condition that occurs as a result of eating food that is contaminated with infectious organism or toxins produced by these infectious organisms. A number of bacteria, viruses or parasites can cause food poisoning, but some of the most common include E. coli and salmonella. Each case of food poisoning varies based on the type of organism that causes the illness; however, general symptoms include nausea, vomiting, diarrhea, fatigue, abdominal pain, stomach cramps, loss of appetite and fever. notes that symptoms may begin within hours of eating the contaminated food and can last from one to 10 days. Most cases of food poisoning do not require medical intervention. It is important to stay hydrated while symptoms persist to avoid dehydration. Those who are severely dehydrated because of the symptoms of food poisoning may require intravenous administration of fluid and electrolytes to normalize fluid and salt balance in the body.

Urinary Tract Infection

A urinary tract infection is an infection that can affect any structure that makes up the urinary tract, which includes the kidneys, ureters, bladder and urethra. A urinary tract infection develops when bacteria enter the body through the urethra, which is the tube that carries urine to the outside of the body, and travel into the bladder and other parts of the urinary system. The National Digestive Diseases Information Clearinghouse states that most urinary tract infections are caused by Escherichia coli, which is normally found in the colon. The most common symptoms of a urinary tract infection include pain during urination, a frequent urge to urinate and passing only small amounts of urine. Other symptoms include pressure and pain in the abdomen, fatigue, shakiness and cloudy urine. Most cases can be successfully treated with a series of antibiotics, although nfections that have traveled to the kidneys may require hospitalization.


The pituitary gland is a small gland attached to the hypothalamus that is located directly below the brain. The pituitary gland releases a number of hormones that act on various areas of the body and are important in carrying out many body functions. Hypopituitarism is a condition in which the pituitary gland does not produce adequate amounts of some or all of its hormones. The condition may be caused by a brain tumor, prior brain surgery, brain infections, stroke, radiation therapy or physical trauma to the head, according to MedlinePlus, a service of the National Institutes of Health. Because the hormones released by the pituitary gland control a number of body functions, hypopituitarism causes a number of symptoms, which include abdominal pain, fatigue, decreased appetite, decreased libido, loss of armpit or pubic hair, low blood pressure, increased sensitivity to cold, vision problems, weight loss and weakness. Hormone therapy is the only way to treat hypopituitarism. If the condition is caused by a brain tumor, the tumor will need to be removed as well.
