What are potential causes for constant vomiting after meals

3 days ago

A female patient about 20 years old, average built and weight, vomits after every meal, including tea or water.

The symptoms have intensified over a period of about 3 months.

The patient has no medication or preexisting conditions.

A gastroscopy and colonoscopy have remained resultless.

The episodes have approximately started (though that might coincidental) after repeated (twice) use of emergency-contraception.

The regular anti-baby pill is no longer applied for about a week, but not inprovement has been achieved.
