What is Nausea?

When you feel any type of discomfort in the upper abdomen along with a feeling of sickness or an imminent urge to vomit, it is nausea. Our body responds to various internal and external stimuli that have the tendency to disturb the normal functioning of our digestive system.

Nausea can be triggered by a wide range of causes. Some common culprits include:


1. Gastrointestinal disorders:

Our body consumes energy from the food we eat, which is composed of various types of ingredients. These can cause different reactions in our body leading to conditions like gastroenteritis, peptic ulcers, gastritis, and gallbladder disease can cause nausea. Sometimes Viral or bacterial infections affecting the digestive system can also cause nausea.


2. Medications:

Other than food consumption, we are also likely to be taking drugs and medicines prescribed. Medical issues that involve you having to consume medications like chemotherapy drugs, antibiotics, opioids, and nonsteroidal anti-inflammatory drugs (NSAIDs), may have nausea as a side effect.


3. Pregnancy:

In women, nausea comes as a high probability when they are pregnant, due to the frequent changes of hormone levels in the body. Nausea and vomiting, often referred to as morning sickness, are common during the early stages.


4. Motion sickness:

The sensory functions of the human body are subjective to each individual and have their share of effects. Sensory conflicts caused by movement, such as during travel by car, boat, or plane, can lead to nausea.


5. Emotional and psychological factors:

If you are not very good at handling your mood fluctuations, or emotions and are struggling with anxiety, you might have nausea during the episodes. Stress and certain other mental health disorders can also trigger or exacerbate nausea.

Once we know about the causes of nausea, it becomes easier to understand the symptoms. It is important to get a clearer picture of the extent of nausea and aid in identifying potential underlying causes. Here are some common symptoms associated with nausea:


1. Vomiting or Retching:

One of the primary symptoms accompanying nausea is vomiting or retching. Conditions like migraine are associated with symptoms of vomiting and nausea. When you get an episode of nausea, you are most likely to get a cramp-like sensation in your stomach, leading to the forceful expulsion of contents through the mouth. This can be distressing and often offer temporary relief from the queasiness associated with nausea.


2. Loss of Appetite:

Due to the effects of nausea on the body, it becomes difficult to feel like eating causing a loss of appetite. The fear of triggering further nausea can make it difficult to consume regular meals. This can result in poor eating habits, leading to potential weight loss and nutritional deficiencies if not managed properly.


3. Excessive Saliva Production:

Nausea is understood by the brain as a forceful process of digestion that increases saliva production. This symptom can contribute to feelings of discomfort and a constant need to swallow. Nausea also has accompanying symptoms like excessive sweating. When the sensation becomes more intense or persists for an extended period. This sweating may be localized to the forehead, face, or palms and can vary in severity.


4. Dizziness or Lightheadedness:

The most commonly understood symptom of nausea is dizziness or lightheadedness. Conditions like diabetes can have these effects on your body. A challenging task during nausea is to maintain balance and perform daily activities. The combination of nausea and dizziness may cause weakness or unsteady foot movement.


5. Abdominal Discomfort or Pain:

Nausea often coincides with abdominal discomfort or pain. The sensation may range from mild discomfort to severe pain, depending on the underlying cause. This abdominal distress could be a sign of conditions like pneumonia which can further contribute to the overall discomfort experienced during an episode of nausea.


Diagnosing Nausea:

It is crucial to diagnose the underlying cause of nausea if it is repetitively occurring in your life. The process involves a comprehensive evaluation of your medical history, physical examination, and tests. It is vital to get a record of your symptoms, triggers, and associated factors from a doctor. If the cause is more complex, then there are blood tests, imaging studies, or endoscopic procedures to rule out or identify it.
