These can include pregnancy, migraines, food poisoning, and more serious health issues like heart attacks or cancer. Understanding the potential causes of nausea can help in identifying the underlying condition and seeking appropriate treatment.

One of the most common causes of nausea is problems with the digestive system. This can include food poisoning, gastritis, peptic ulcers, or gastroenteritis. In these cases, nausea is often accompanied by other symptoms such as vomiting, diarrhea, and abdominal pain. If you experience persistent nausea along with these symptoms, it is important to seek medical attention.

Certain medications can also cause nausea as a side effect. This is particularly common with chemotherapy drugs, opioids, and certain antibiotics.

Nausea is a well-known symptom of early pregnancy, often referred to as "morning sickness". Despite its name, morning sickness can occur at any time of the day.
