Ask someone to drive you to urgent care or an emergency room if: 1  Nausea and vomiting are accompanied by pain or a severe headache, especially if you haven't had this type of headache before.

Essentially, leaky gut syndrome (âintestinal hyperpermeabilityâ) is condition that happens as a consequence of intestinal tight junction malfunction. These âtight junctionsâ are the gateway between your intestines and what is allowed to pass into the blood stream.
For others, leaky gut results in difficulty gaining weight. That often occurs when there are digestive issues such as nausea, heartburn, and/or diarrhea that lead to a struggle to find foods you can consume without feeling worse. It also occurs because nutrients are not well absorbed when the gut is leaky.
