Nausea is a feeling of unease and discomfort in the stomach, usually accompanied by the desire to vomit. Vomiting, also known as emesis, is the forceful expulsion of stomach contents through the mouth, often providing temporary relief from nausea.
Effective management of nausea and vomiting involves preventing dehydration, addressing malnutrition, and minimising disruptions to daily life. Keep reading to learn their causes, symptoms, management, and prevention in detail.
Underlying Medical Conditions of Nausea and Vomiting
Nausea and vomiting can be caused by a variety of medical conditions, including viral gastroenteritis, food poisoning, and chemotherapy-induced nausea. Other causes include chronic illnesses, such as diabetes or kidney disease.
Nausea and vomiting are common with disorders such as gastritis, peptic ulcers and irritable bowel syndrome (IBS). These symptoms are exacerbated by blockages and motility problems within the digestive tract (such as gastroparesis).
The brain's regulatory mechanisms are substantially impaired, and therefore, pronounced nausea and vomiting are common in neurological conditions such as migraines, seizures, strokes and hydrocephalus.
These distressing gastrointestinal symptoms are exacerbated by labyrinthine and demyelinating disorders and increased intracranial pressure.
Symptoms of Nausea and Vomiting
Key to treating the severe and underlying causes of nausea and vomiting is recognising the symptoms.
Symptoms commonly associated with nausea and vomiting include abdominal pain, dizziness, increased salivation, and perspiration, especially when tiredness and loss of appetite are also present.
Individuals experiencing persistent nausea and vomiting over 24 hours should seek medical help. Situations that need immediate attention include hematemesis, severe headache, and inability to retain fluids.
Diagnostic Approaches for Nausea and Vomiting
Since nausea and vomiting can be caused due to various factors, accurate diagnosis is important for treatment to be effective.
The important aspect of a patient’s history is the details, which include recent illnesses, medications, and lifestyle.
Physical examination is for the detection of dehydration, abdominal tenderness, and neurological deficits.
Blood tests and urine analysis can reveal infections, metabolic imbalances, or organ dysfunction in the lab.
Imaging studies, including ultrasounds and CT (Computed Tomography) scans, of the gastrointestinal or central nervous systems can detect structural abnormalities.
Medical Management of Nausea and Vomiting
Medical management is about treating the symptoms and underlying causes of nausea and vomiting.
Medications commonly prescribed include antihistamines, dopamine antagonists, and serotonin receptor antagonists. They work by acting on their particular pathways in the brain and gut system, all targeting the same symptoms.
Nausea and vomiting must be managed by targeting the underlying etiological factor. The administration of antibiotics or specialised preventive therapies for causative conditions varies depending on the condition.
In cases of severe vomiting, dehydration must be prevented by intravenous fluids and electrolyte replacement. Chronic cases require nutritional support through dietary adjustment or enteral feeding.
Non-Pharmacological Management of Nausea and Vomiting
Medical treatments are generally supplemented with non-pharmacologic approaches when they are mild or preventive.
Eating twice a day and avoiding fatty, spicy, strong-smelling foods can help reduce symptoms. Bland foods like crackers, rice, and bananas can calm the system.
Nausea and vomiting can be managed with behavioural therapies, including relaxation techniques, systematic desensitisation and cognitive behaviour therapy.
Non-pharmacological interventions such as biofeedback and hypnosis also help relaxation and control anticipatory symptoms of these conditions.
Well-known home remedies with anti-nausea properties include ginger tea, peppermint tea and chamomile tea.
Alternative therapies, such as acupuncture and acupressure, can also effectively alleviate symptoms.
Special Considerations for Nausea and Vomiting
Physiological conditions of certain populations necessitate particular approaches to manage nausea and vomiting.
Morning sickness, or pregnancy-related nausea, is common. Dietary changes and vitamin B6 (Pyridoxine) supplementation may control mild cases, while hospitalisation is needed for severe cases (hyperemesis gravidarum).
Complications of anaesthesia and surgical procedures commonly include post-operative nausea and vomiting (PONV). Key strategies to minimise risk are prophylactic antiemetics and adequate hydration.
Prevention Strategies for Nausea and Vomiting
To prevent nausea and vomiting, identifying potential triggers and making healthier lifestyle and dietary choices can be beneficial.
Foods, smells, and activities that have been linked to nausea should be avoided. Using anti-nausea medications or wristbands before travel can help people prone to motion sickness.
A healthy diet, staying hydrated, and regular physical activity can lessen the incidence of nausea. Meditation and deep breathing are also helpful.
Complications of Chronic Nausea and Vomiting
If chronic nausea and vomiting are not treated, they can result in serious health problems.
Dehydration and electrolyte imbalances can be precipitated by nausea and vomiting in vulnerable populations, i.e., the elderly and young children.
Symptoms may include weakness, decreased urination and dry mouth, which can be severe and include hypovolemic shock and kidney failure.
Prolonged vomiting significantly cuts off nutrient absorption, causing a deficiency of essential vitamins and minerals.
Deficiencies such as these are detrimental to overall health and slow recovery from illness. The most notable deficiencies are pyridoxine (vitamin B6), cobalamin (vitamin B12), calciferol (vitamin D), magnesium, zinc, and phylloquinone (vitamin K).
Conclusion
Managing nausea and vomiting is essential for improving patient outcomes and enhancing quality of life. Timely diagnosis, effective treatment, and necessary lifestyle adjustments play a vital role in alleviating these complex and distressing symptoms.
Early intervention is crucial to preventing complications such as dehydration, malnutrition, and long-term health issues. A holistic approach that combines pharmacological and non-pharmacological methods offers comprehensive care.
