Nausea
Nausea is defined as the sensation of needing to vomit. The intensity of this sensation can vary widely among individuals; some may experience mild discomfort, while others may face severe distress. Nausea is one of the most common health disturbances, with nearly everyone experiencing it at least once in their lifetime. It is important to note that nausea itself is not classified as a disease but rather a symptom of an underlying health issue. Accompanying symptoms of nausea may include dizziness, diarrhea, vomiting, fever, abdominal pain, and a reduced frequency of urination. It is crucial to recognize that certain symptoms may indicate a serious health condition, such as generalized fatigue, chest pain, difficulty breathing, confusion, a rapid heartbeat, or even fainting.
Causes of Nausea
There are numerous factors that can lead to feelings of nausea, with the most notable causes outlined below:
- Heartburn and Gastroesophageal Reflux Disease (GERD): Both heartburn and GERD can cause stomach contents, including acids, to regurgitate into the esophagus, resulting in nausea.
- Gastric Infections: The stomach can become infected with bacteria, as occurs with food poisoning, or virus, which can induce nausea.
- Medication Side Effects: Some medications can cause nausea, especially when taken in combination. Numerous prescription and over-the-counter drugs, as well as dietary supplements, may have nausea as a side effect. It is essential to inform healthcare providers about all medications being taken to receive proper guidance to mitigate nausea. Examples of such medications include some chemotherapy agents and certain antidepressants.
- Food Consumption: Consuming foods that trigger allergies or eating heavily spiced and fatty foods can provoke nausea. Additionally, overeating is also a common cause.
- Pain: Nausea can be a symptom associated with severe pain, such as that from gallstones, pancreatitis, or kidney stones.
- Motion Sickness: Individuals prone to motion sickness frequently report feelings of nausea, along with dizziness and vomiting.
- Ulcers: Stomach or intestinal ulcers can lead to sensations of heartburn and nausea, especially after eating.
- Hormonal Changes: Fluctuations in hormone levels, particularly in females, can result in nausea. For instance, nearly 50% of pregnant women experience nausea, particularly in the early months. Similarly, hormonal changes from birth control pills may also induce this sensation.
- Additional Causes: Besides the aforementioned, various health issues may cause nausea, including:
- Hepatitis.
- Migraine headaches.
- Brain tumors.
- Head trauma.
- Meningitis.
- Glaucoma.
- Low blood sugar levels.
- Alcohol consumption.
- Post-anesthetic nausea in individuals recovering from surgery.

- Inhale deeply and obtain fresh air.

- Consume small amounts of cold beverages; many find relief from carbonated drinks.
