Overview
Nausea and vomiting are common symptoms that can arise from a variety of underlying conditions.
How it works in your body (pathophysiology):
Nausea and vomiting happen through specific interactions in your body:
- Gastrointestinal tract: This is your digestive system. It sends signals to your brain when something is wrong, like an upset stomach.
- Central nervous system: This is your brain and spinal cord. They process signals from your digestive system and decide if you need to vomit.
- Vestibular system: This part of your inner ear helps with balance. It can trigger nausea if you feel dizzy or motion sick.
Statistics and Prevalence in Australia
While specific prevalence data for nausea and vomiting as standalone symptoms are not available in the latest Australian health statistics, these symptoms are commonly associated with various acute and chronic conditions. The Australian Institute of Health and Welfare (AIHW) and the Australian Bureau of Statistics (ABS) primarily report on chronic conditions and major diseases, with nausea and vomiting often being secondary symptoms [2].
Symptoms and Clinical Presentation
Nausea is characterised by an unpleasant sensation in the stomach that often precedes vomiting. Vomiting is the forceful expulsion of stomach contents through the mouth. Early symptoms may include dizziness, increased salivation, and a feeling of warmth. Advanced symptoms can involve dehydration and electrolyte imbalances if vomiting is severe or prolonged. Red flag symptoms requiring immediate medical attention include severe abdominal pain, blood in vomit, and signs of dehydration such as reduced urination and confusion [1], [3].
Causes and Risk Factors
The causes of nausea and vomiting are diverse and can be categorised into gastrointestinal, central nervous system, and systemic origins. Common causes include:
- Gastroenteritis: Often viral or bacterial, leading to inflammation of the stomach and intestines.
- Pregnancy: Particularly in the first trimester, known as morning sickness.
- Medications: Such as chemotherapy agents and some antibiotics.
- Migraine: Often accompanied by nausea and sensitivity to light and sound.
- Motion Sickness: Caused by conflicting signals to the brain from the inner ear and eyes [1], [2].
Risk factors include a history of motion sickness, pregnancy, and certain medical treatments like chemotherapy [1].
Diagnosis
The diagnostic approach in Australia involves a thorough clinical assessment to determine the underlying cause. This includes a detailed patient history and physical examination. Laboratory tests may include blood tests to check for electrolyte imbalances and infections. Imaging studies, such as abdominal ultrasound or CT scans, may be necessary to rule out structural causes. The Royal Australian College of General Practitioners (RACGP) provides guidelines for managing these symptoms, emphasising the importance of identifying red flags that necessitate further investigation [1], [2].
Treatment Options in Australia
Treatment for nausea and vomiting in Australia is guided by the underlying cause. General management strategies include:
- Pharmacological Treatments: Antiemetics such as ondansetron and metoclopramide are commonly used. In pregnancy, pyridoxine and doxylamine are recommended as first-line treatments [1], [3].
- Non-Pharmacological Strategies: Dietary modifications, such as eating small, frequent meals and avoiding triggers, can be beneficial. Acupressure and ginger supplements are also used as complementary therapies [2].
- Hydration and Electrolyte Balance: Oral rehydration solutions are recommended to prevent dehydration, especially in cases of severe vomiting [1].
Medicare and the Pharmaceutical Benefits Scheme (PBS) provide coverage for many of these treatments, ensuring accessibility for Australian patients [1].
Living with Nausea And Vomiting
Effective management of nausea and vomiting involves regular monitoring and follow-up care. Patients are encouraged to keep a symptom diary to identify potential triggers and patterns. Education on self-management strategies, such as dietary adjustments and stress reduction techniques, is crucial. Psychosocial support may be necessary for individuals experiencing chronic symptoms, impacting their quality of life [1], [2].
Prevention
Preventive strategies focus on addressing known risk factors and triggers. For individuals prone to motion sickness, pre-emptive use of anti-motion sickness medications and behavioural strategies, such as focusing on the horizon, can be effective. Pregnant women may benefit from dietary adjustments and vitamin supplementation to reduce the incidence of morning sickness. For those on medications known to cause nausea, dose adjustments or alternative therapies may be considered [1], [2].
