Coughing and vomiting white foam could be linked to acute asthma or accidental ingestion of substances like hydrogen peroxide.
Coughing and vomiting white foam might be concerning. One possible reason could be acute asthma, where vomiting can be a main symptom. This happens because the body is reacting to the difficulty in breathing, and sometimes it can make you vomit. Another reason might be if someone accidentally ingests a substance like hydrogen peroxide. This can cause foamy vomiting because of the way hydrogen peroxide reacts in the stomach.
If you experience these symptoms, it is important to talk to a healthcare provider to understand the cause and get the right help.
