It is often related to digestive issues such as acid reflux, gastroesophageal reflux disease (GERD), or gastrointestinal conditions. It can also be caused by certain sleeping positions, such as sleeping flat on your back or right side, which can make it easier for stomach acid to flow back up into the oesophagus. In addition, vomiting in your sleep can be a symptom of other underlying health conditions, such as anxiety, medication side effects, peptic ulcers, or pregnancy. If you are frequently vomiting in your sleep and choking, it is important to consult a healthcare professional for advice and treatment.

Vomiting in sleep can be a symptom of an underlying condition, such as a gastrointestinal disorder
Other possible causes of vomiting in sleep include specific sleeping positions, such as sleeping flat on the back or right side, which can exacerbate acid reflux by allowing stomach acid to flow back into the oesophagus. Additionally, certain health conditions like sinusitis, sleep apnea, and pregnancy can increase the likelihood of vomiting during sleep.
To prevent vomiting in sleep, it is recommended to adjust the sleeping position by elevating the head and upper body. This can be achieved by using extra pillows, mattress tilter, or an under-mattress wedge, which helps keep stomach acid from rising into the oesophagus. It is also important to consult a healthcare professional to address any underlying health conditions and receive personalised advice and treatment.

Acid reflux, GERD, and pregnancy are common causes
Vomiting in your sleep can be a frightening experience, and it is often a result of acid reflux, GERD, or pregnancy. Acid reflux occurs when the muscle separating the stomach from the food pipe is weakened, allowing stomach contents to enter the oesophagus and irritate its lining. This can cause a burning sensation in the throat, nausea, vomiting, belching, and chest discomfort. Sleeping flat on the back or right side can exacerbate acid reflux by making it easier for stomach acid to flow back into the oesophagus. To prevent this, it is recommended to sleep with the head elevated, using extra pillows or adjustable beds, which helps keep acid or food from moving up into the oesophagus.
GERD, or Gastrointestinal Oesophageal Reflux Disease, is a health condition characterised by acid reflux symptoms. It can cause a build-up of stomach acid that may force an individual to vomit during the night, especially when lying down for extended periods. This position promotes the flow of stomach contents back into the oesophagus, leading to potential choking and vomiting. Adjusting the sleeping position to maintain an elevated head can help prevent these issues.
Pregnancy is another common cause of vomiting during sleep. Pregnant women experience increased pressure on the stomach, leading to a higher likelihood of reflux. Sleeping on the left side with a body pillow or similar device can help alleviate this issue.
While acid reflux, GERD, and pregnancy are the most common causes of vomiting in sleep, other possible causes include gastrointestinal conditions, medication side effects, anxiety, and peptic ulcers. It is always recommended to consult a healthcare professional to determine the underlying cause and receive appropriate treatment or advice.

Adjust your sleeping position to prevent vomiting in sleep
Vomiting in your sleep can be caused by various reasons, including acid reflux, gastroesophageal reflux disease (GERD), stomach bugs, and anxiety. To prevent this from happening, you can adjust your sleeping position. Here are some tips to help you adjust your sleeping position and reduce the risk of vomiting in your sleep:
Elevate Your Upper Body
One of the most effective ways to prevent vomiting in your sleep is to sleep with your head and torso elevated. This position helps to keep stomach acid and contents in your stomach by utilising gravity. You can achieve this by raising the head of your bed by about six to eight inches or using a pillow, foam wedge, or mattress tilter to lift your body from the waist up.
Sleep on Your Left Side
The anatomical structure of the stomach and oesophagus makes sleeping on your left side preferable. When you lie on your left side, your stomach is positioned below your oesophagus, making it less likely for stomach acid to creep back up into your throat and cause vomiting.
Avoid Sleeping on Your Back or Right Side
Sleeping flat on your back or your right side can exacerbate acid reflux and make it easier for stomach acid to flow back up into your oesophagus. This can increase the risk of vomiting in your sleep.
Use a Wedge or Mattress Tilter
If you find it challenging to maintain an elevated position while sleeping, consider using an under-mattress bed wedge or a mattress tilter. These tools are designed to increase the incline of your upper body and can be adjusted to your preferred level of comfort.
Remember, while adjusting your sleeping position can help reduce the risk of vomiting in your sleep, it is important to consult a healthcare professional to address any underlying conditions and determine the best treatment for your specific needs.

Avoid lying flat on your back or right side
Vomiting in your sleep can be a symptom of an underlying condition, such as a gastrointestinal disorder. It can be caused by acid reflux, GERD, sinusitis, or even pregnancy. If you are vomiting in your sleep, it is important to consult a healthcare professional to determine the best treatment for your specific condition.
To avoid lying flat on your back or right side while sleeping, you can try the following:
Use pillows for support
Try placing a pillow under your knees before bed. Your knees should be slightly bent and feel comfortable. You can also place a pillow under your lower back while you sleep, but be mindful that if the pillow is too large or thick, it may create more discomfort. If you are worried about rolling onto your back or right side during sleep, place pillows around your midsection and hips to prevent you from rolling over.
Adjust your mattress
Instead of using pillows, you can adjust the incline of your mattress by using an under-mattress bed wedge. This is a long-lasting, comfortable, and portable solution that allows you to choose your preferred incline by sliding the wedge up or down.
Sleep on your side
Side sleeping is generally recommended for pregnant individuals. You can use pregnancy pillows to support your back and stomach while lying on your side. Side sleeping is also beneficial for snorers or anyone with sleep apnea as it keeps the airways open.
Avoid certain foods
Fatty, spicy, and acidic foods can increase heartburn symptoms and contribute to acid reflux, which is a common cause of vomiting in your sleep. Therefore, it is advisable to avoid these types of foods, especially close to bedtime.
Consult a healthcare professional
If you are experiencing persistent symptoms or severe nausea and vomiting, it is important to seek advice from a doctor. They can determine the underlying cause and provide appropriate treatment or refer you to a specialist if needed.

Consult a healthcare professional to determine the best treatment
Vomiting in your sleep can be a frightening and dangerous experience. It is often related to digestive concerns, such as acid reflux, gastroesophageal reflux disease (GERD), or gastrointestinal conditions. Less commonly, it could be a symptom of cyclic vomiting syndrome (CVS), which involves recurring episodes of vomiting and nausea, or gastroparesis, which is an injury to the vagus nerve that helps your stomach muscles contract. In some cases, vomiting in your sleep may be related to anxiety or medication side effects.
If you are experiencing frequent vomiting in your sleep, it is important to consult a healthcare professional to determine the best treatment for your specific condition. Here are some steps you can take:
- Seek medical advice: Visit your doctor or a gastroenterologist, who can help diagnose the underlying cause of your vomiting. Be sure to mention any new medications you have started taking, as this could be a contributing factor.
- Follow medical recommendations: Depending on the diagnosis, your healthcare provider may prescribe medications to relieve nausea and suppress stomach acid production. They may also recommend dietary changes, weight management, or other measures to address the issue comprehensively.
- Adopt safer sleeping positions: To prevent choking and reduce the risk of vomiting in your sleep, try sleeping with your head elevated. You can use extra pillows or adjust the incline of your mattress by using a bed wedge or mattress tilter. Sleeping on your left side is also recommended, as it can help keep stomach acid down.
- Address underlying health conditions: In addition to implementing sleeping position strategies, it is crucial to address any underlying health conditions that may be causing your symptoms. This may involve managing GERD, anxiety, or other gastrointestinal disorders.
- Consider home remedies: Along with medical treatment, some home remedies can help ease nausea and vomiting. These include drinking ginger or peppermint tea, sucking on peppermint, or eating light, bland foods in small amounts.
- Monitor symptoms and follow-up: Pay attention to the frequency and severity of your symptoms. If your vomiting persists or is accompanied by other concerning symptoms, such as headaches or unexplained weight loss, consult your healthcare provider again for further evaluation and treatment adjustments.
Remember, vomiting in your sleep can be dangerous, and it is always best to seek professional advice to ensure you receive the most appropriate treatment for your specific condition.
