Stomach pain and diarrhea are common symptoms that everyone experiences at some point. When these symptoms come on suddenly, they usually signify some type of infection that may be caused by bacteria, viruses or parasites. Stomach pain and diarrhea that occur frequently or persist over time may indicate an underlying chronic digestive disorder.
Food Poisoning
Food poisoning is an acute illness that occurs after ingesting contaminated food. Food may be contaminated by viruses, bacteria, parasites or the toxins that these organisms release. Contamination can occur at any time during food production, which includes growing, processing storing and shipping, but cross-contamination, or the transfer of infectious organisms between surfaces, is most often the cause, according to MayoClinic.com. The most common symptoms of food poisoning include nausea, vomiting, diarrhea, stomach pain, cramps, loss of appetite, fatigue and fever. Symptoms generally last a few days but may as long as ten days. Food poisoning usually goes away on its own without treatment, however young children or elderly adults may need administration of intravenous fluids and salts.
Irritable Bowel Syndrome
Irritable bowel syndrome is a condition in which the intestinal muscles either contract too quickly and forcefully or too slowly and feebly. When the intestines contract too quickly, the intestinal contents pass through too hastily and proper absorption is not possible. When the intestines contract too slowly, contents become stagnant in the intestines. Symptoms of irritable bowel syndrome include bloating, gas, mucus in the stool, diarrhea, stomach pain and cramps. Stress and certain foods often exacerbate these symptoms, according to the American Academy of Family Physicians. The most effective treatment method for irritable bowel syndrome consists of eating a balanced diet that includes adequate amounts of fiber and avoiding trigger foods. If symptoms are severe, medications can be prescribed to alleviate specific symptoms.
Crohn's Disease
Crohn's disease is characterized by inflammation in the digestive tract. The inflammation may occur anywhere, but most often affects the part of the small intestine called the ileum, according to the National Digestive Diseases Information Clearinghouse. Crohn's disease is believed to be a result of an abnormal immune response to bacteria in the intestines. The most common symptoms of Crohn's disease are stomach pain and diarrhea, but other possible symptoms include rectal bleeding, weight loss, skin problems and fever. Crohn's disease is usually treated with a combination of anti-inflammatory drugs, immunosuppressants and diet changes. If this is ineffective, surgery may be needed to remove the damaged part of the intestines.
