Irritable bowel syndrome, or IBS, and food poisoning can cause similar symptoms, but the two conditions are distinctly different. IBS is a chronic digestive disorder, while food poisoning is an isolated instance that's caused by eating or drinking something that's contaminated. Some people with mild IBS symptoms may mistake IBS episodes as food poisoning. If you notice that you develop nausea, cramping, bloating, diarrhea or constipation consistently, make an appointment with your doctor.
Irritable Bowel Syndrome
IBS is a digestive disorder that affects about one in six Americans, according to MedlinePlus. The condition is related to the way the colon and brain communicate. Although it is assumed that IBS is caused by a defect in the structure of the digestive system, it is actually caused by nerve malfunctions between your brain and colon. The communication breakdown can cause you to become constipated, have diarrhea or develop stomach pain. The exact cause of this condition is still not fully understood. Some people develop IBS after an intestinal infection and others experience symptoms from stress.
Food Poisoning
Food poisoning is the result of consuming contaminated food or beverages. It is commonly caused by improper food handling, cross-contamination or undercooked food. The food or beverage has an infectious organism in it, such as a parasite, bacteria, toxin or virus, according to MayoClinic.com. Most symptoms develop within four to 12 hours after you've ingested contaminated food. Food poisoning symptoms can last from one to 10 days. Call your doctor if you vomit for more than two days or develop constant diarrhea for more than three days.
Symptoms
Symptoms from IBS and food poisoning are similar. Both conditions can cause nausea, vomiting, stomach pain, abdominal cramping, diarrhea, fatigue, gas, bloating and weakness. Symptoms that develop from IBS are manageable through diet modification and identifying the triggers of your symptoms. Symptoms from food poisoning are not treatable except to increase liquid intake to prevent dehydration. A modified diet may help calm your stomach and reduce the severity of your nausea and diarrhea.
Trigger
If you've been diagnosed with IBS and you get food poisoning, your IBS symptoms may worsen during the duration of the illness. Call your doctor if you notice blood in your stool or in your vomit. This may be a sign of a more serious complication or disease.
