Why Do I Feel Like Throwing Up after a Workout

You’re at the gym and you just finished a workout. Maybe it was leg day, or some sort of endurance workout. Whatever it is, you’ve had an exhausting workout session and now you’re feeling sick. I used to feel like throwing up after every workout. Nothing was physically wrong it’s just what happens sometimes when you work out. And now I feel compelled to help other people who have that feeling because it can sap your motivation pretty fast if you let it continue for too long.

Blood flow increases in muscles and skin when you workout and also decreases to the abdominal organs. Other reason is eating too soon before workout.

It is recommend to not push yourself too hard and slowly increase your stamina and endurance. Let the body get used to work out first.

The body uses different muscles to run than it does to walk

The muscles that are used in running are the glutes, hamstrings, quads and calves. The body also uses stabilizing muscles in the core and back. When you run, your heart rate increases and your breathing becomes more rapid.

Your body releases endorphins (hormones) that make you feel good  this is why many people enjoy exercising. Running can also cause nausea if the person is out of shape or if they have not eaten enough before or during their workout session.

Excessive stress

The following are some of the most common reasons why people feel nauseated after a workout:

  • Excessive stress: When you exercise, your body releases endorphins  hormones that act as natural painkillers to help you feel better. But overtraining can put too much stress on your body and cause nausea. Some people get nauseous if they exercise too hard or too long, while others may experience it after any kind of physical activity.
  • Dehydration: If you don’t drink enough water before, during and after exercise, you could become dehydrated. Dehydration can cause symptoms like dizziness and lightheadedness, which can sometimes lead to nausea.
  • Too much caffeine: Drinking large amounts of caffeine can make anyone feel jittery and nauseated. If you’re sensitive to caffeine or drink too much coffee during the day  especially before exercising  this could lead to feeling sick during your workout or even afterward if your body takes longer than usual to process the caffeine from your system.
  • Food poisoning: Food poisoning often causes nausea and vomiting in its victims because bacteria or viruses in food can irritate the stomach lining so severely that it causes inflammation and sickness.

Pushing yourself too hard

It’s easy to get caught up in the moment and push yourself to your limits, but this can prevent you from reaching your goals. You should feel slightly tired after a workout, but not exhausted or out of breath.

If you’re feeling like you need a break after just 10 minutes, then you’re pushing yourself too hard. You should also be able to walk comfortably and talk without gasping for air afterward.

If you’re taking part in a sport that involves contact such as boxing or wrestling, then it’s normal for your body to become sore after each session. However, if you find it hard to move after your workout or if pain persists long after the session has ended, then this could be a sign of overtraining.

Many people don’t lift weights the right way

They’re using improper form, which can create muscle imbalances and lead to injury. The best way to lift weights is to keep your back straight and chest up, keep your knees slightly bent and maintain proper balance at all times. Exercise is supposed to be fun, but for many people, it’s not. It’s a chore that has to be done or else you’ll get fat.

 If you hate working out so much that you never want to do it again, maybe it’s time to find something else that you enjoy more. Having a headache after working out could be due to dehydration or low electrolytes. In any case, it is best to stay hydrated during your workout and afterwards. If you are very thirsty after a workout, then you need to drink more water before and during your workout.

Dehydration can cause muscle cramps and headaches. If you feel like throwing up after a workout, it could be that you have not eaten enough food or drunk enough water before the exercise. Nausea is one of the most common side effects of exercising and is usually temporary.

It can be caused by a number of factors such as eating too much before exercising, lack of sleep or stress at work. If you feel nauseous during an intense workout, then try taking deep breaths and slow down to prevent yourself from vomiting while working out.

Some people may experience vomiting due to an underlying health condition

  • Throwing up after a workout is not uncommon. However, if you vomit more than once or twice a week, it may be a sign that you’re overdoing it at the gym. Some people may experience vomiting due to an underlying health condition. If you have any chronic medical conditions or take medications, talk to your doctor about the possibility of side effects. You should also see your doctor if you have frequent vomiting that occurs without exercise and lasts longer than 24 hours.
  • If your nausea and vomiting aren’t related to another condition, they could be brought on by changes in your body’s electrolyte balance. Electrolytes are minerals found in blood and other fluids throughout the body that are essential for normal cell function. They include sodium chloride (salt), potassium, calcium, magnesium and hydrogen phosphate (bicarbonate).
  • Your kidneys regulate electrolyte levels in the bloodstream by removing excess amounts through urine production. When you sweat during exercise, you lose electrolytes through perspiration; this can make it difficult for your kidneys to maintain proper electrolyte concentrations in blood.


If you are feeling light-headed and nauseous after a workout session, then it is likely that you may be suffering from low blood sugar. This could be related to exercise or starvation because of fasted cardio. Carbohydrates help with energy production and fuel your brain, which is what helps prevent nausea. If this condition persists, then it is advised to visit the doctor and discuss health related concerns.
