Why Do I Keep Throwing Up After I Workout?

Throwing up after a workout is a sign that you are overtraining. This can lead to serious health problems, so it is important to take a step back and re-evaluate your workout routine.

Possible Causes

Vomiting after exercise is a common complaint, especially among the more intense types of exercise. Generally, there are a few potential causes for this, ranging from dehydration to low blood sugar. It is important to identify the issue and address it in order to avoid long-term health problems. In this article, we will explore the different possible reasons why someone may be throwing up after exercise and what can be done to prevent it.


Dehydration is a common cause for nausea and vomiting after a workout. When exercising, your body sweats to help cool you down, but this also causes dehydration since you’re losing fluids that your body needs in order to function properly. Without proper hydration, it can become difficult for your body to process food and electrolytes which can result in nausea and throwing up after workouts. To prevent dehydration it’s important to replace electrolytes lost through sweat by drinking plenty of water and replenishing with sports drinks or electrolyte tablets when exercising for prolonged periods of time.


If you are having frequent issues with throwing up after exercise, it is possible that you are working out too hard or too long. Over-exertion can cause a build-up of toxins in the body that may lead to vomiting. Additionally, pushing yourself beyond your limits may increase your heart rate and blood pressure too quickly. This can trigger nausea or vomiting, resulting in symptoms experienced after exercise.

Some of the most common signs of over-exertion include: feeling worn out after even a short period of exercise, feeling dizzy or faint during or after exercise, extreme sweating, muscular pain and soreness for days following a workout. If any of these symptoms occur to you during your workout sessions, consider adjusting your activities and/or intensity levels to avoid further aggravation on body systems. Taking a few days rest can help restore balance allowing for a successful resumption of regular workouts with no ill consequences such as nausea and vomiting.

Eating too much before exercising

Eating too much, especially if done too close to exercise, can cause gastrointestinal distress and vomiting. Before beginning any physical activity, it’s important to check in with yourself on how full you are feeling. If you’re stuffed or hungry, it may be best to take a break until you are at a comfortable level of fullness. If you do decide to eat before your workout and experience nausea afterward, try eating smaller meals or snacks more frequently throughout the day as opposed to one large meal prior to exercising. Doing this has been shown to reduce levels of nausea. It’s also helpful when choosing what will be consumed pre-workout since some foods can be more difficult for the body to digest than others. Foods like high fat or greasy meals may be harder for the body process and could trigger an upset stomach after working out.


If you find yourself feeling nauseous and throwing up after you workout, there are some steps you can take to prevent it from happening again. It’s important to understand the root cause of your issue so you can take the right steps to prevent it. In this section, we will discuss the different strategies you can take to stop feeling nauseous after a workout.

Drink plenty of fluids before and during exercise

It is essential to drink plenty of fluids before, during, and after workouts to help prevent vomiting. Being dehydrated can make it much more difficult for the body to cool itself. As such, it is important for athletes and exercisers to drink plenty of fluids before and during workouts in order to stay hydrated. Ideally, fluids should be consumed at relatively frequent intervals or with larger volumes ingested less often. Furthermore, sports beverages or drinks that contain sodium are recommended as these substances help retain fluid longer than plain water. Additionally, limiting caffeine intake prior to physical activity may reduce dehydration and the risk of nausea or vomiting.

Start with light exercises and gradually increase intensity

If you are prone to throwing up after working out, it’s important to start off with light exercises and gradually increase intensity as you get used to physical activity. This may include activities such as walking, light jogging or biking. Start with between 10-20 minutes at a moderate pace and once you sense that your body is comfortable with this level of exercise, you can incrementally increase the intensity by increasing speed or the length of your sessions. By doing this, you are allowing your body time to adjust to steady movement and enabling yourself to become familiarised with what’s being asked from a physical level.

Eat a light snack before exercising

Eating a light snack before exercising can help settle your digestion, boost energy, and prevent throwing up after a workout. Choose foods that are low in fat and fiber, as these can be harder to digest during exercise. Additionally, select foods with complex carbohydrates like whole grain toast or oatmeal, as these can provide sustained energy during your workout. Additionally, you may want to avoid foods high in sugar or protein unless your exercising is more intense or you are trying to build muscle. Finally, stay hydrated throughout your workout with plenty of water or electrolytes to prevent dehydration which can cause nausea during exercise.


Working out and then throwing up after is a common occurrence for many people. It can be caused by a variety of factors including dehydration, fatigue, or even a medical condition. Fortunately, there are several treatments available to help control the symptoms. Some of the treatments include proper hydration and diet, rest, and even medication. Let’s take a closer look at the different treatments that are available.

Rest and rehydrate

If you have been repeatedly throwing up after intense workouts, it’s important to take some time to rest and rehydrate your body. Giving yourself some time to recuperate allows your body to reset and get back into balance. Try taking one or two days off from extended workouts and spending them instead relaxing, sleeping more, and drinking plenty of fluids like water or electrolyte-rich options such as coconut water. Eating nutritious meals that contain hydrating fruits like watermelon can also help replenish lost nutrients and hydration levels. Additionally, consider talking with your physician about the health benefits of taking an appropriate multivitamin supplement following a tough workout to better support your ongoing well-being.

Avoid exercising until symptoms subside

If you are throwing up after exercising, it is important to rest and not do any strenuous physical activity until your symptoms subside. This can help prevent dehydration and further medical complications, such as electrolyte imbalance.

In general, it’s best to limit exercise when you’re feeling unwell and allow ample time for recovery. Patients who have an underlying condition that causes vomiting should talk to their doctor before returning to physical activity, as there may be additional measures that may need to be taken in order for them to safely return to workouts.

It is also important that you take the time to replenish lost nutrients from vomiting, such as electrolytes by drinking fluids or adapting your diet accordingly. If you are experiencing ongoing nausea after workouts or other gastrointestinal issues that could be caused by exercise, consult with your doctor in order to determine the underlying cause and find a treatment plan tailored for you.

See a doctor if symptoms persist

If you have been experiencing persistent vomiting after exercising, it is highly recommended that you seek professional medical advice. This could be an indication of an underlying medical condition or other issues with your body’s response to exercise. Consulting a doctor is the best way to properly diagnose and treat the issue. During your consultation, make sure to provide a detailed description of your symptoms, such as how long they last, how often they occur, any other associated symptoms (e.g. dehydration), and what type of exercises lead to the issue. Your doctor may suggest various treatments depending on their diagnosis—these may include medications, lifestyle behavior modifications such as avoiding high-intensity workouts or eating before exercise, and even physical therapy aimed at improving muscle strength or motor control if there are underlying musculoskeletal problems identified upon examination.

When to See a Doctor

Throwing up after a workout can be a cause of concern and should not be taken lightly. It can occur due to numerous factors, including over-exertion and dehydration. It is important to figure out why your body might be reacting this way and determine if it is a sign of something serious. Let’s discuss when it is necessary to see a doctor if you are experiencing vomiting after a workout.

If symptoms don’t improve

If vomiting episodes persist or become more severe after the initial 48 hours or if there is blood in the vomit, a doctor should be consulted. If your symptoms do not improve within four to seven days, it is usually considered safe to contact a physician.

The doctor can assess the situation and ensure that there are no additional signs of a serious condition requiring medical attention. They may recommend an imaging scan, such as an X-ray or CT scan, to aid in diagnosis and treatment. Blood tests may also be needed if there is suspicion of infection such as food poisoning or other conditions like pancreatitis and digestive tract obstructions. If further investigation is needed, the doctor will likely refer you to a specialist for further assessment.

A variety of treatments are available for those who continue throwing up after working out and experience significant discomfort. Depending on the underlying cause of your symptoms, you may benefit from medications such as anti-nausea agents prescribed by your physician or herbal remedies recommended by a naturopath or Traditional Chinese Medicine practitioner that can help reduce nausea and vomiting. You might also find relief with lifestyle modifications like rehydrating with sports drinks during intense exercise and making dietary adjustments so your body can recover from exercising more efficiently.

If there is blood in the vomit

If you’ve been vomiting after working out and notice that there is blood in the vomit, seek medical attention immediately. Throwing up blood can be a sign of serious medical complications, including bleeding in the stomach, ulcers or even, in some cases, tumors. A doctor should be able to diagnose your symptoms and determine the underlying cause. Even if it turns out to be something less serious like food poisoning or dehydration, it’s still important to have a professional check you out. In some situations the blood could come from your mouth or nose and not from your digestive system at all; a doctor will be able to help figure out where it’s coming from so that you can take care of any health concerns quickly.

If you have a fever or abdominal pain

If you have been throwing up after every workout for more than a week and/or you experience any of the following symptoms—a fever of more than 101 degrees, severe abdominal pain, difficulty breathing, profuse sweating, dizziness—it is important to see your doctor immediately. Throwing up after a workout isn’t always an indication of a more serious medical issue; however, it can be a sign that something is wrong.

Causes for frequent vomiting after working out can include but are not limited to: heat exhaustion or dehydration due to prolonged exposure to heat or inadequate hydration or electrolyte intake; overexertion as a result of pushing yourself too hard during exercise and straining muscles; gastroenteritis (an inflammatory bowel disease); overconsumption of non-steroidal anti-inflammatory medications (NSAIDs); dietary imbalances such as low carbohydrates or high proteins; and emotional stress associated with exercising.

Your doctor will diagnose your condition through reliable tests such as a physical exam, urinalysis and other potential tests that help identify underlying health issues. Proper diagnosis is paramount in treating the underlying cause and return you back to training safely. Your doctor may also recommend lifestyle changes such as preventing dehydration while working out by drinking fluids before and during exercise, adjusting your diet if necessary, gradually increasing intensity when exercising or taking time off between workouts.
