R11 Nausea and vomiting

Name of the Condition

• Common name(s): Nausea and vomiting
• ICD-10 code: R11

Summary

Nausea and vomiting are symptoms characterized by an unpleasant sensation in the stomach (nausea) and the forceful expulsion of stomach contents through the mouth (vomiting). These symptoms are non-specific and can arise from a wide range of underlying conditions, affecting individuals across all age groups.

Causes

Nausea and vomiting can be triggered by numerous factors, including gastrointestinal infections, motion sickness, pregnancy, medications (such as chemotherapy or opioids), food poisoning, and systemic illnesses like migraines or metabolic disorders. They may also result from psychological stress or overconsumption of alcohol.

Risk Factors

Risk factors include a history of gastrointestinal disorders, pregnancy, certain medications, travel (especially by sea or air), and conditions like migraines or inner ear problems. Dehydration, poor diet, and recent exposure to contaminated food or water may also increase susceptibility.

Symptoms

The primary symptoms are nausea (a queasy stomach sensation) and vomiting. Additional symptoms may include abdominal discomfort, sweating, salivation, dizziness, or lightheadedness. The severity and frequency can vary depending on the underlying cause.

Diagnosis

Diagnosis typically involves a medical history review and physical examination. Further evaluation may include blood tests to check for infections or metabolic issues, imaging studies (e.g., ultrasound or CT scan) if structural abnormalities are suspected, or endoscopy for persistent symptoms.

Treatment Options

Treatment focuses on addressing the underlying cause. Options may include antiemetic medications to control nausea and vomiting, rehydration (oral or intravenous), dietary modifications (e.g., bland foods), and managing any identified conditions (e.g., infections or migraines).

Prognosis and Follow-Up

Prognosis depends on the underlying cause. Most cases resolve with appropriate treatment, but follow-up may be necessary for persistent or severe symptoms to monitor for complications or recurrence.

Complications

Potential complications include dehydration, electrolyte imbalances, malnutrition, or aspiration (inhalation of vomit into the lungs), particularly in severe or prolonged cases.

Lifestyle & Prevention

Preventive measures include avoiding triggers (e.g., certain foods, motion), staying hydrated, eating small, frequent meals, and managing stress. For motion sickness, over-the-counter remedies or behavioral techniques may help.

When to Seek Professional Help

Seek medical attention if vomiting is severe, persistent, or accompanied by symptoms like high fever, severe abdominal pain, blood in vomit, or signs of dehydration (e.g., dizziness, reduced urination).

Tips for Medical Coders

Use R11 for nausea and vomiting when the underlying cause is not specified or documented. Ensure documentation supports the presence of both symptoms. If a specific cause is identified, use the appropriate ICD-10 code for that condition instead.
