VOMITING UNDIGESTED FOOD
WHAT THIS SYMPTOM USUALLY MEANS
Vomiting undigested food can indicate delayed stomach emptying, GI inflammation, megaesophagus, or obstruction. Timing matters: vomiting soon after eating suggests regurgitation or stomach issues; hours later suggests motility disorder.
MOST COMMON CAUSES
MILD CAUSES
• Eating too fast
• Overeating
• Stress
MEDICAL CAUSES
• Delayed gastric emptying
• Megaesophagus
• Food intolerance
• IBD
• Acid reflux
• Pancreatitis
EMERGENCY CAUSES
• Obstruction
• GDV (dogs)
• Severe pancreatitis
RED FLAGS: WHEN THIS IS AN EMERGENCY
• Vomiting undigested food repeatedly
• Swollen/bloated abdomen
• Painful abdomen
• Food comes up immediately every time
• Regurgitation + weakness (megaesophagus risk)
AT-HOME CARE YOU CAN START NOW
• Feed small meals
• Slow-feeder bowl
• Keep pet upright 10–15 minutes after eating
• Bland diet temporarily
WHAT A VETERINARIAN WILL CHECK
• X-rays (obstruction, megaesophagus)
• Bloodwork
• Barium study
• Ultrasound
• Neurologic evaluation (megaesophagus is neurological)
MOST LIKELY DIAGNOSES
• Megaesophagus
• Delayed gastric emptying
• Gastritis
• Pancreatitis
• Foreign body
BREEDS OR AGES AT HIGHER RISK
• German Shepherds (megaesophagus)
• Older dogs with motility decline
• Brachycephalics
WHEN YOU SHOULD SCHEDULE A VETERINARY VISIT
• Within 24 hours
• Same day if repeated or severe
EXPECTED RECOVERY TIME
Depends heavily on cause — from hours (mild gastritis) to lifelong (megaesophagus).
HOW THIS SYMPTOM RELATES TO LONGEVITY
Chronic vomiting of food leads to malnutrition, aspiration pneumonia, and accelerated aging.
WHEN TO CONSIDER A LONGEVITY CONSULT
• Recurrent episodes
• Weight loss
• Senior pets
• Known GI/neurologic disease
