Nausea is a distressing symptom characterised by an uneasy sensation in the stomach, often preceding vomiting. It can result from various factors, such as infections, motion sickness, pregnancy, or medical treatments like chemotherapy. The body's natural response to toxins or discomfort triggers a complex interplay of signals between the brain and digestive system, leading to a strong sense of unease.
Accompanied by increased salivation, sweating, and a heightened sensitivity to odours, nausea serves as a protective mechanism, urging individuals to mitigate potential harm. While usually temporary, persistent or severe nausea may require medical attention to identify and address underlying causes.
Both adults and children can experience nausea. Patients who are undergoing cancer treatments, such as radiation therapy or chemotherapy pose a higher risk of nausea. Pregnant women in their first trimester also experience nausea usually known as “morning sickness.” Research says that 70% to 80% of pregnant people experience nausea, while 25% to 55% experience vomiting.

Any change in the Immune system and central nervous system functioning can trigger dizziness and nausea. Many different things can cause these changes. Some common causes of nausea include:
Infections: Nausea from viral or bacterial GI infections triggers an immune response, often with diarrhoea or vomiting to expel pathogens.
Motion Sickness: Conflicting sensory signals cause nausea in cars, planes, or boats due to the brain's misinterpretation of motion.
Pregnancy: Hormonal changes in early pregnancy, like elevated HCG levels, affect the digestive system, leading to temporary nausea.
Chemotherapy: Drugs irritate the stomach lining, triggering the brain's vomiting centre, and causing nausea in cancer patients. Antiemetics help manage chemotherapy-induced nausea.
Migraines: Sensitivity to light and sound, accompanied by severe headache and nausea; changes in brain activity and blood flow may contribute.
Nausea can be diagnosed using the following methods
Clinical Assessment: Doctors will conduct a thorough medical history and physical examination to identify potential causes of nausea
Laboratory Tests: Blood and urine tests help doctors rule out infections, organ dysfunction, or metabolic imbalances that may contribute to nausea offering valuable diagnostic insights.
Imaging Studies: Procedures such as abdominal ultrasounds, CT scans, or MRIs can show structural abnormalities in the digestive system, aiding in the diagnosis of conditions like gallstones, tumors, or inflammation that is causing nausea.
Endoscopy: A flexible tube with a camera is inserted through the mouth or nose to examine the oesophagus, stomach, and upper intestine. This enables direct visualization of potential ailments like ulcers, inflammation, or tumors contributing to nausea.
Electrocardiogram (ECG): In cases where cardiovascular issues are suspected, an ECG measures the heart's electrical activity, helping identify conditions like arrhythmias or cardiac ischemia, which may manifest with symptoms like nausea.
Antiemetic Medications: These medications target the brain's vomiting center, blocking signals that cause migraines and nausea and providing relief from nausea symptoms.
Fluid Replacement: Rehydration with clear fluids, electrolyte solutions, or intravenous fluids helps alleviate nausea associated with dehydration, restoring electrolyte balance and improving overall health.
Dietary Adjustments: Consuming bland, easily digestible foods like crackers, toast, or broth can help settle the stomach and provide nausea relief. Avoiding spicy, greasy, or heavy meals may prevent exacerbation of symptoms.
Acupressure or Acupuncture: Applying pressure to specific points on the body or undergoing acupuncture sessions may help alleviate nausea by promoting relaxation and balancing energy flow, according to some alternative medicine practices.
Behavioral Therapies: Techniques such as deep breathing, guided imagery, or progressive muscle relaxation can help manage nausea by reducing stress and anxiety, which can exacerbate symptoms. These therapies aim to promote relaxation and distract from discomfort, aiding in symptom relief.
