R11: Nausea and vomiting

Nausea and vomiting are common symptoms that can arise from various illnesses or conditions. Nausea is described as an unsettling feeling usually in the stomach area that often precedes vomiting but does not always lead to it. Vomiting, or throwing up, is the bodily act of forcibly ejecting stomach contents through the mouth. These conditions can be triggered by several factors including certain foods, motion sickness, pregnancy, intense pain, emotional stress, infections and some diseases of the digestive system. They may also be caused by medical treatments such as surgery, radiation therapy and chemotherapy. While usually short-lived, prolonged or severe cases of nausea and vomiting can lead to dehydration and need medical attention. It's crucial to identify the underlying cause to manage these symptoms effectively.
