It is not normal for urine to come out while vomiting and may indicate a medical issue. This could be due to a condition called stress urinary incontinence, where the muscles that control urination weaken during episodes of increased abdominal pressure, such as vomiting. It is recommended to consult with a healthcare professional who can evaluate your symptoms and provide appropriate treatment options. In some cases, lifestyle changes, pelvic floor exercises, or medication may help manage this condition.
