Constipation and Vomiting: When to Worry and What to Do

Constipation commonly causes bloating and nausea, but vomiting is not a typical symptom of simple constipation. If vomiting occurs alongside constipation, it may indicate a more serious issue such as:

• Bowel obstruction (ileus, mechanical blockage)
• Fecal impaction with proximal distension
• Medication side effect (e.g., opioids)
• Metabolic disturbance (e.g., hypercalcemia)
• Gastroenteritis coinciding with constipation

When to Seek Medical Care

• Vomiting + no bowel movement for >3 days
• Severe abdominal pain or distension
• Blood in stool or vomit
• Inability to pass gas
• Fever, dehydration, or weight loss

Consult a healthcare provider promptly for evaluation. Do not self-treat with laxatives if obstruction is suspected.
