6. Abdominal Cramps

The ingestion of food contaminated with bacteria is often followed by stomach cramping which is also an involuntary reaction of the body as it tries to push out its bowel contents in order to get rid of the infection. Muscles of the stomach start contracting in waves, causing pain and discomfort all over the abdomen. These spasms are usually accompanied by vomiting and diarrhea which could last for a few hours after being infected. In order to lessen the pain, laying down on your back as well as drinking clear fluids, most especially water, is advisable. Otherwise, over-the-counter medicines are available to alleviate the symptoms.
