14 Reasons Why you have Upper Abdominal Pain
12. Food Poisoning
Food poisoning is a common cause of stomach pain, including upper abdominal discomfort. Food poisoning can begin with simple abdominal discomfort.
Pain may start out mild and become worse. The pain will eventually be accompanied by other symptoms. There are many causes of food poisoning. Food poisoning is more common when food is eaten in restaurants.
Food poisoning can be caused by food that has been left out too long, not refrigerated, cooked incorrectly, or from unsanitary factory conditions. Food poisoning does not spread, but can affect many people all at once. If a large number of people eat the same food, or eat food prepared in the same kitchen, it can affect entire schools, hospitals and even whole cities. Food poisoning is a condition that must be allowed to run its course, but nausea medication can be prescribed in order to reduce symptoms.
