Common Causes Of Nausea

Overeating Or Eating Certain Foods

The digestive system is part of a delicate balance, and what individuals put into it affects how their bodies feel. Sometimes the underlying cause of nausea isn't a medical condition at all, but is simply a temporary condition caused by something an individual ate. Eating too much can cause individuals to feel nauseous, as can eating certain kinds of foods. A food intolerance occurs when an individual's digestive system has trouble processing certain foods, but isn't fully allergic to them. If someone has a food intolerance, they might experience nausea after eating some kinds of food. Some of the most common food intolerances are to gluten, large amounts of salt, and food that's undergone a large amount of chemical processing and preservation. Eating a lot of sugar at once can also lead to nausea and symptoms of high blood sugar, especially if individuals have an underlying condition like diabetes. When individuals eat too much food at once, it causes their digestive muscles to become stretched past the point of pain, which is what causes nausea.

Stomach Ulcers

Stomach ulcers are a potential cause of nausea, and they can also be a very serious medical condition. These ulcers, also called gastric ulcers, occur when painful sores form in the lining of the stomach. Stomach ulcers are one kind of peptic ulcer disease. When individuals talk about peptic ulcers, they are referring to any ulcers that affect either the small intestines or stomach. An ulcer forms when there's a reduction in the mucus layer protecting the stomach from the digestive juices. This allows the acid that breaks down food to also eat through the stomach lining. If the ulcer isn't treated properly, it can become severe, but some stomach ulcers can also be easily cured. Nearly all ulcers are caused by a bacterial infection or by long-term use of nonsteroidal anti-inflammatories like naproxen. There are rare cases where Zollinger-Ellison syndrome will lead to ulcers because it increases the body's acid production. Ulcers can cause nausea, and they also tend to cause burning pain in the abdomen that gets more intense with an empty stomach.
