Final answer:
Food poisoning symptoms include nausea, vomiting, diarrhea, aches, and fever, and may cause severe dehydration and other complications. Gastritis, enteritis, and gastroenteritis are inflamed conditions of the GI tract, while ulcers are commonly caused by Helicobacter pylori infection or NSAID-induced damage.
Step-by-step explanation:
Food poisoning is caused by consuming contaminated food and can lead to a range of symptoms including nausea, vomiting, diarrhea, aches, and fever. These symptoms can sometimes result in severe dehydration and other serious complications. The underlying issues may arise from infections or intoxications of the gastrointestinal (GI) tract. Inflammation of the stomach lining is known as gastritis, while inflammation of the intestines is referred to as enteritis.
When both areas are inflamed, it's called gastroenteritis. Conditions like hepatitis affect the liver and colitis impacts the colon, commonly leading to watery stools or dysentery. Notably, peptic ulcers in the stomach or duodenum usually stem from a Helicobacter pylori infection, intensified by stress and substances like NSAIDs, which can impede the protective mucosal barrier.
