Evaluation of nausea and vomiting.

Area of Science:

• Gastroenterology
• Internal Medicine
• Symptomatology

Background:

• Nausea and vomiting are common symptoms with diverse etiologies.
• Acute causes are often self-limiting infections or iatrogenic factors.
• Chronic nausea and vomiting necessitate a systematic diagnostic approach.

Purpose of the Study:

• To outline an effective evaluation strategy for nausea and vomiting.
• To differentiate between acute and chronic causes.
• To guide diagnostic testing based on clinical presentation.

Main Methods:

• Emphasis on comprehensive history and physical examination.
• Initial diagnostic workup limited to basic laboratory tests and radiography.
• Further investigations guided by clinical suspicion.

Main Results:

• History and physical examination are pivotal in identifying the cause.
• Acute symptoms frequently stem from infections, inflammation, or iatrogenic factors.
• Chronic symptoms often indicate gastrointestinal, central nervous system, endocrine, metabolic, or psychiatric conditions.

Conclusions:

• A systematic approach focusing on history and physical exam can often determine the cause of nausea and vomiting.
• Diagnostic testing should be tailored to clinical suspicion, prioritizing emergency detection.
• Empiric antiemetic therapy is appropriate when the cause remains elusive.
