Carrot-Colored Vomit: Causes Beyond Eating Carrots

Orange Vomit: Differential Diagnosis

Vomit appearing orange or "carrot-colored" is not always due to recent carrot consumption. The color reflects a mix of gastric contents, bile, and partially digested food. Key causes:

Food-Related

• Carrots, sweet potatoes, pumpkin, tomato-based foods, orange-colored drinks/snacks.
• Food dyes (e.g., FD&C Yellow #6, Red #40).

Medical Causes

• Bile-stained vomit: Yellow-green to orange; indicates duodenal contents reflux—suggests intestinal obstruction, pyloric stenosis (infants), or post-gastrectomy.
• Gastrointestinal bleeding: Partially digested blood ("coffee grounds") can appear dark orange-brown.
• Medications/supplements: Iron supplements, rifampin, certain antacids.
• Infections: Rotavirus, norovirus—vomiting may be colored by recent diet.
• Cyclic vomiting syndrome: Recurrent episodes; color varies with intake.

When to Seek Care

• Persistent vomiting >24 hrs (12 hrs for children).
• Signs of dehydration (dry mouth, decreased urine, dizziness).
• Severe abdominal pain, distension, or bilious vomiting in infants.
• Blood in vomit or "coffee grounds" material.
• High fever, lethargy, or confusion.

Document recent food intake, medications, and associated symptoms to help clinicians determine the cause.
