Nausea
Nausea is the unpleasant sensation of being about to vomit, whether or not you actually do. While nausea is common in cases of food poisoning, it can also occur from a variety of causes, including migraines, motion sickness, and overeating.
Nausea caused by food poisoning usually appears one to eight hours after a meal. It acts as a warning to your body that something potentially harmful has been ingested. It might be made worse by a slowing of your bowel movement, which occurs when your body tries to keep the toxin in your stomach. If you're feeling nauseated, consider some of natural cures to help relieve your symptoms.
