After i eat many times i feel a bit sick also i experience the same nervous stomach when i have anxiety. what sould i do?

Check With MD: The gastrointestinal tract is closely linked to anxiety. So much so, that one can have situations where one is unsure what is actually causing the symptoms. The only way to get a definitive answer to a question like this is to meet with your primary care physician. She/he is trained to take a clinical history and to perform a physical examination to determine the exact cause of such anxiety.
