Why This Happens
Vomiting is an extension of nausea—when the stomach is very full and moves slowly, it can trigger the vomiting reflex. Usually happens when doses are increased too quickly.
If side effects are limiting your progress, a provider can adjust dosing or switch medications based on your response. The right medication match can make all the difference.
