Vomiting

What Vomiting Means

Vomiting, also known as emesis, is when your stomach forcefully pushes its contents out through your mouth. It is often preceded by nausea, which is the feeling of wanting to throw up. Vomiting can happen for many reasons, such as infections, motion sickness, pregnancy, certain medicines, or medical conditions. It is a natural reflex that helps your body get rid of harmful substances or irritants.

Vomiting in Cancer Care

In cancer treatment, vomiting is a common side effect, especially from chemotherapy and radiation therapy. These treatments can irritate the stomach or affect the brain areas that control nausea and vomiting. Vomiting may also be a symptom of some cancers themselves. Doctors often give medicines called antiemetics before treatment to help prevent or reduce vomiting. These medicines work by blocking signals in the body that trigger nausea and vomiting.

Vomiting related to cancer treatment can happen at different times. It may occur shortly after treatment (acute vomiting), days later (delayed vomiting), or even before treatment starts if previous experiences cause anxiety (anticipatory vomiting). Managing vomiting is important because if it is not controlled, it can lead to dehydration, changes in body salts (electrolytes), and weight loss.

What You Might Experience and See

You might feel sick to your stomach before vomiting, or you might vomit suddenly without warning. Vomiting can be uncomfortable and sometimes painful. In children receiving cancer treatment, vomiting is also a serious concern and is managed similarly to adults. If vomiting continues without producing vomit, it is called dry heaves, which can be distressing.

Sometimes, vomiting can cause other problems like irritation or small tears in the throat, or damage to teeth from stomach acids. If you notice blood in vomit or severe symptoms, it is important to tell your healthcare provider.

Where You May See the Term Vomiting

You might see the word vomiting or emesis in your medical records, treatment plans, or medication lists. It may also appear in information about side effects of cancer treatments or in discussions about symptom management. Understanding this term can help you better communicate with your care team about your symptoms and treatment options.

What Vomiting Does Not Always Mean

Vomiting does not always mean your cancer is getting worse or that treatment is failing. It can be a temporary side effect that can be managed. Also, not all nausea leads to vomiting, and not all vomiting is caused by cancer or its treatment. Other causes like infections, medications, or other health conditions may be involved.

Questions to Ask Your Care Team

If you experience vomiting, it’s helpful to ask your healthcare providers about ways to prevent or control it. You might ask what medicines are available, how to take care of yourself during vomiting episodes, and when to seek urgent care. Also, ask about signs of dehydration or complications to watch for.

Understanding This Information

This information is meant to help you understand vomiting in the context of cancer care. It does not replace advice from your healthcare team. Everyone’s situation is different, so always talk with your doctors or nurses about your symptoms and treatment plan. They can provide guidance tailored to your needs.

Next Steps

If you or a loved one is experiencing vomiting, especially if it is severe, persistent, or accompanied by other symptoms like dehydration or blood, contact your healthcare provider. They can help adjust your treatment or provide medicines to ease symptoms and keep you safe and comfortable.
