6-Nausea and vomiting
In many cases, hernias may lead to abnormal intestinal traffic and in severe cases, create a partial or total obstruction of the gastrointestinal tract. In these cases, one of the leading signs is nausea, and the patient may also start vomiting. Nausea due to an abdominal hernia is an alteration of the peristalsis in the gastrointestinal tract. Instead of going forwards it starts flowing backward because there is an obstruction the intestines can’t overcome.
