Why Do I Get Freckle-Like Red Dots on My Face After Vomiting?
Post-emetic facial petechiae (PEFP), also known as the "measles rash of vomiting," refers to the tiny red dots that can appear on your face after vomiting or retching excessively. They're usually harmless and typically fade within a few hours or days.
Causes:
- Increased pressure during vomiting: The force of vomiting can cause numerous capillaries in your face to rupture, leading to bleeding under the skin.
- Vasodilation: Vomiting can also cause dilation of blood vessels in your face, increasing blood flow and making the ruptured capillaries more visible.
- Prolonged vomiting: Frequent or prolonged bouts of vomiting can further increase capillary damage and the extent of the rash.
Treatment:
PEFP usually doesn't require specific treatment. It resolves spontaneously once the underlying cause is addressed. Avoiding excessive vomiting and using over-the-counter antiemetics can help prevent its recurrence.
When to Seek Medical Attention:
In most cases, PEFP is a benign condition. However, if the rash is severe, accompanied by other symptoms such as fever, vomiting that doesn't subside, or bleeding from your nose or mouth, it's important to seek immediate medical attention.
