Based on the information available, there is no direct evidence to suggest that aspirin can stop changes in nausea. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) primarily used to treat pain, reduce inflammation, and lower fever [1]. It works by inhibiting the production of prostaglandins, hormone-like substances that cause pain and inflammation [1].

Nausea, on the other hand, is a common symptom that can be associated with various medical conditions, such as gastrointestinal disorders, food poisoning, motion sickness, or certain medications [2]. Nausea can also be a side effect of chemotherapy or radiation therapy [2].

While aspirin may help alleviate symptoms related to inflammation or fever, there is no specific evidence supporting its effectiveness in treating or preventing nausea [3]. If you are experiencing nausea, it is recommended to consult a healthcare professional for appropriate treatment options [2].
