Sudden abdominal pain after eating may be a sign of a more serious condition. An isolated instance of abdominal pain may be related to indigestion or food poisoning, if symptoms progress. Consistent abdominal pain after eating may be a sign of a chronic dietary condition, such as irritable bowel syndrome, food intolerance or a food allergy. Avoid eating any foods that cause abdominal pain until you can be evaluated by a gastroenterologist.
Isolated Instances
An isolated instance of sudden abdominal pain after eating may be related to indigestion, commonly caused by overeating, eating too fast, or eating foods that are high in fat or that contain a lot of spices. If the abdominal pain continues to get worse, call your doctor because you may have food poisoning. Food poisoning occurs when you eat a food that is contaminated with an infectious organism, such as a toxin, bacteria or virus. Food poisoning symptoms will also cause a low-grade fever, fatigue, vomiting and nausea. Most symptoms from food poisoning subside between one and 10 days.
Irritable Bowel Syndrome
Sudden abdominal pain after eating may be caused by irritable bowel syndrome, or IBS. IBS is a common digestive condition that affects about 20 percent of the U.S. population, according to the National Digestive Diseases Information Clearinghouse. The primary symptoms of IBS are chronic diarrhea, constipation or both. The cause of IBS is unclear but eating certain foods and increased stress can trigger symptoms. Secondary, yet common, symptoms of IBS include stomach pain, bloating, gas and cramping. IBS is treated with medication, dietary modification and reduction in stress.
Food Intolerances
Food intolerances will cause abdominal pain to occur within 30 minutes or up to a few hours after eating food. The American College of Gastroenterology states that food intolerances are caused by the inability to digest certain sugars and proteins found in different foods. Gluten, lactose, fructose, MSG and histamine are common ingredients that cause intolerance in some people. Food intolerances are incurable and are treated with an elimination diet. Certain food intolerances, such as gluten intolerance, can cause long-term damage to your intestines if not treated.
Food Allergy
Food allergies will cause abdominal pain and other gastrointestinal complications after consuming a food that triggers an allergic reaction. Food allergies are not caused by the digestive system, but are rather the result of a hypersensitivity of your immune system to food proteins. The most common foods that cause an allergic reaction include wheat, soy, eggs, peanuts, tree nuts, milk and fish. Food allergies can cause severe allergic reactions that could lead to death if not treated.
