Vomiting white material can sometimes be due to stomach mucus, undigested food, or saliva mixed with gastric secretions. It may also occur if the stomach is empty and the vomit is mostly bile-free fluid.

Possible causes include mild irritation of the stomach lining, acid reflux, or early stages of a viral stomach infection. If the vomiting persists, worsens, or is accompanied by other symptoms like abdominal pain, dehydration, or blood, it is important to seek medical evaluation promptly.

What you can do now:

• Stay hydrated by sipping small amounts of clear fluids.
• Avoid solid food until vomiting subsides.
• Rest and monitor for any new or worsening symptoms.

If vomiting continues beyond a day or is severe, please consult a gastroenterologist or your primary care doctor for a thorough assessment and appropriate treatment. If you experience severe abdominal pain, persistent vomiting, or signs of dehydration, seek emergency care immediately.
