Feel Like Throwing Up? What You Should and Shouldn’t Do According to Doctors

Introduction

Vomiting is a natural reflex designed to protect the body by expelling harmful substances, such as toxins or spoiled food. In certain rare and medically appropriate circumstances, inducing vomiting may be considered, for example, when advised by a healthcare professional and other interventions have proven ineffective. 

Some individuals may attempt to trigger vomiting by stimulating the gag reflex, consuming warm salt water, or through exposure to unpleasant stimuli. However, it is essential to understand that self-induced vomiting should only be done when absolutely necessary and always under medical supervision. Improper or repeated use can pose serious health risks¹.

When Should You Make Yourself Throw Up?

Inducing vomiting is a serious action and should only be considered in specific circumstances, under medical guidance as follow²: 

1. Medical Emergencies

If someone has ingested a potentially harmful substance, inducing vomiting might seem like a helpful response. However, it is vital to seek immediate advice from a healthcare professional or poison control centre before taking any action. In some cases, inducing vomiting can cause further harm, particularly if the substance is corrosive, sharp, or toxic when re-exposed to the oesophagus or mouth. 

2. Swallowed Poison or Harmful Substance

If you accidentally ingest poison or a toxic chemical, your first step should be to seek immediate medical advice. While inducing vomiting might seem like a quick remedy, it is not always appropriate and, in some cases, can cause further harm. Always consult a healthcare professional,such as your doctor or contact a certified poison control centre for guidance. These professionals can assess the situation and advise the safest course of action based on the substance involved. 

3. Food Poisoning

If you are unsure whether you have consumed spoiled or contaminated food, your body may naturally attempt to expel it through vomiting as a protective response. In some cases, encouraging this reaction may seem beneficial. However, it is important to seek medical advice before attempting to induce vomiting, as it may not always be the safest or most effective course of action depending on the situation and symptoms. 

4. Eating Disorders (Caution)

In cases of eating disorders such as bulimia nervosa, individuals may feel compelled to induce vomiting after episodes of overeating, often in an attempt to lose weight or feel “cleansed” of the food consumed. This behaviour is harmful and can lead to serious physical and mental health consequences. It should never be considered a solution or coping strategy. If this reflects your experience or that of someone you know, it is vital to seek professional help. Support from medical professionals, mental health specialists, or eating disorder services can make a significant difference in recovery and overall well-being. 

How to Induce Vomiting: Techniques

In rare cases, and only under the guidance of a healthcare professional, inducing vomiting may be considered appropriate. If such a need arises, the following methods are sometimes used in clinical or emergency settings. It is crucial, however, to consult a doctor or poison control centre before attempting any of these approaches: 

1. Using Your Finger

One of the most common methods to induce vomiting is by manually stimulating the gag reflex. This involves gently inserting clean index and middle fingers into the back of the throat to trigger the reflex. If done correctly, it may result in vomiting almost immediately³. 

2. Drinking Warm Salt Water

Another traditional method involves drinking warm salt water. To try this, dissolve two teaspoons of salt in a glass of warm water and drink it quickly. The high concentration of salt may irritate the stomach lining, triggering nausea and possibly inducing vomiting as the body attempts to expel the excess sodium². 

3. Gargling with Water

Gargling with warm water for several minutes may help stimulate the gag reflex, which can lead to nausea and potentially induce vomiting. Some believe that adding salt to the water may intensify the effect, though this is not medically recommended without professional guidance².  

4. Using a Toothbrush

 If using your fingers feels uncomfortable, a clean toothbrush may serve as an alternative to trigger the gag reflex. Gently rubbing the back of your tongue with the bristles can produce a similar effect, potentially leading to vomiting³. 

5. Thinking about Vomiting

If using your fingers feels uncomfortable, a clean toothbrush may serve as an alternative to trigger the gag reflex. Gently rubbing the back of your tongue with the bristles can produce a similar effect, potentially leading to vomiting.  

6. Gargling with Egg Whites

Gargling with raw egg whites is an unconventional and often unpleasant method that some believe may trigger vomiting. The strong smell and texture can induce nausea in certain individuals, potentially leading to vomiting as a reflexive response². 

7. Thinking of an Unpleasant Smell or Sight

In some cases, strong emotional or sensory stimuli, such as recalling an unpleasant sight, smell, or memory can provoke nausea and potentially lead to vomiting. This reaction stems from the body’s natural protective mechanisms, where the brain responds to perceived threats by attempting to expel them. 

8. Drinking a Mustard Solution

A mixture of mustard powder and water has traditionally been used as a home remedy to induce vomiting. Mustard is believed to have mild emetic properties, which may cause nausea and, in some cases, lead to vomiting when consumed in large amounts⁴. 

9. Taking Baking Soda

Sodium bicarbonate, commonly known as baking soda, may cause nausea and vomiting when consumed in certain quantities. This reaction is often due to its ability to disrupt the body’s acid-base balance⁵.

10. Bloodroot Herb

Bloodroot is a plant known for its traditional medicinal uses, and in moderate doses, it has been reported to induce vomiting due to its emetic properties. However, it is important to note that bloodroot is a potent herb, and excessive or unsupervised use can be toxic and lead to serious health complications, including damage to the gastrointestinal tract and other organs⁶. 

Most individuals who engage in self-induced vomiting are aware of its harmful effects and often express a desire to stop. This behaviour can lead to a range of health complications, including electrolyte imbalances, which may impact heart function; tooth decay caused by frequent exposure to stomach acid; acid reflux and oesophageal irritation; as well as gastrointestinal issues such as constipation and bloating. Additionally, repeated vomiting can result in a sore throat and a hoarse voice due to irritation of the throat and vocal cords. Given these risks, inducing vomiting should never be taken lightly and must only be considered under the direct guidance of a healthcare professional.

Things to Do After You Throw Up

If you have induced vomiting—whether under medical guidance or otherwise—it is important to take appropriate aftercare steps to support your recovery and minimise harm. Vomiting can be physically taxing and may lead to dehydration, throat irritation, and loss of essential minerals. Here are some key aftercare measures to consider⁷: 

1. Rinse your Mouth

After vomiting, stomach acid can remain in the mouth, which may damage the teeth and gums over time. To reduce this risk, it is advisable to rinse your mouth thoroughly with plain water. Avoid brushing your teeth immediately, as the enamel may be temporarily weakened by the acid, wait at least 30 minutes before doing so. 

2. Drink Water 

Vomiting can lead to dehydration, as the body loses fluids and essential electrolytes. It is important to rehydrate by drinking small sips of water gradually rather than consuming large amounts all at once, which may irritate the stomach. Staying well-hydrated supports recovery and helps restore balance in the body. 

3. Take Rest

After vomiting, the body is often in a state of physical stress and fatigue. It is advisable to lie down and rest, keeping your head elevated above the rest of your body. This position helps reduce the risk of aspirating (inhaling) any remaining vomit and supports overall recovery. Allowing your body time to rest is an important part of the aftercare process. 

If you frequently feel the urge to make yourself vomit, you may be experiencing bulimia nervosa. This is an eating disorder characterised by episodes of binge eating, where a person consumes large amounts of food in a short period and feels a loss of control during these episodes. This is often followed by compensatory behaviours aimed at preventing weight gain, such as purging through self-induced vomiting, excessive use of laxatives or diuretics, fasting, or engaging in excessive exercise.

Side Effects of Induced Vomiting

It is important to recognise that inducing vomiting can lead to a range of side effects, some of which may be serious. 

1. Dehydration

Vomiting can result in the loss of fluids and electrolytes from the body, leading to dehydration. To help prevent this, it is essential to drink adequate amounts of water and maintain proper hydration⁸. 

2. Electrolyte Imbalance

Vomiting can lead to the loss of essential electrolytes, resulting in an imbalance within the body. This may cause symptoms such as fatigue, dizziness, and weakness⁸.

3. Aspiration

There is a risk of inhaling vomit into the lungs during vomiting, which can obstruct the airway and lead to serious breathing difficulties⁸. 

4. Damage to the Esophagus

Frequent vomiting can damage the lining of the oesophagus due to repeated exposure to stomach acids. This damage may result in inflammation, bleeding, or even tears in the throat lining⁸.

Precautions While Inducing Vomiting

To ensure a safer experience, it is important to follow certain precautions when attempting to induce vomiting: 

1. Follow Correct Techniques

Ensure that you adhere to the recommended methods outlined above and avoid any self-induced techniques that may cause harm to your body. 

2. Avoid Frequent Induction

Frequent self-induced vomiting can lead to health problems, including damage to the throat, teeth, and gums. It is important to avoid making yourself vomit regularly. 

3. Consult a Medical Professional

If you experience the urge to induce vomiting, it is advisable to seek guidance from a healthcare professional rather than attempting to do so on your own. Proper medical advice can ensure your safety and address any underlying issues. 

Seeking Support for Eating Disorders

For individuals experiencing the urge to induce vomiting as a result of an eating disorder, it is crucial to seek professional support and treatment. Early intervention can significantly improve outcomes and overall well-being². 

• Professional help: Expert advise from therapists, dieticians, and healthcare providers can help identify and treat eating disorders and guide the right plan of action to break unhealthy habits.  
• Support groups: Joining a support group for individuals experiencing eating difficulties can provide significant relief. These groups offer a safe and supportive environment where members can share their challenges and experiences. 
• Self-help techniques: In addition to professional treatment, self-help methods such as meditation and mindfulness may assist individuals in managing eating disorders and promoting emotional well-being. 

How to Alleviate Nausea without Inducing Vomiting

Nausea can be managed without having to make yourself throw up. Here are some simple ways to help relieve nausea⁹: 

1. Herbal Teas

Herbal teas like ginger or peppermint can help soothe nausea. Ginger tea has anti-nausea properties, while peppermint tea can relax the stomach muscles. 

2. Using Aromatherapy

Inhaling essential oils such as lavender, peppermint, or lemon may help to alleviate nausea. These scents are known for their calming properties and can reduce feelings of queasiness. 

3. Acupressure

Applying gentle pressure to specific points on your wrist, known as acupressure points, can help relieve nausea. This technique is based on traditional practices and may offer relief. 

4. Deep Breathing Techniques

Practicing deep breathing exercises can help to calm both the mind and body, potentially reducing feelings of nausea. Taking slow, deep breaths may assist in settling the stomach. 

5. Fresh Air

Moving to a well-ventilated area or opening a window to allow fresh air can help alleviate nausea, particularly if you are in a stuffy or enclosed environment. 

6. Avoid Spicy or Oily Foods

Eating bland, easily digestible foods can help soothe an upset stomach. It is advisable to avoid spicy, greasy, or rich foods, as they may worsen nausea. 

7. Over-the-Counter Medications

Over-the-counter medications may help manage nausea; however, it is important to consult a healthcare professional before using any medication to ensure it is suitable for your specific condition. 

8. Homeopathic Therapies

If you are considering homeopathic treatments for nausea, it is important to consult a healthcare professional beforehand. They can offer guidance on safe and appropriate options that are tailored to your individual needs.
