Vomiting Without Weight Loss

CLINICAL DIAGNOSTIC MANUAL

Vomiting without weight loss is a symptom that can be associated with various gastrointestinal and extra-gastrointestinal conditions. Unlike vomiting with weight loss, this symptom typically does not significantly compromise the patient’s nutritional status.

However, the presence of recurrent or persistent vomiting necessitates a diagnostic evaluation to identify the underlying cause and prevent complications such as dehydration and electrolyte imbalance.
