Is it normal to feel nauseous after exercise
Now more and more people are keen on sports and fitness. Some of them will choose to exercise on an empty stomach in the morning, thinking that it can achieve good weight loss and exercise results, but they don't want to exercise on an empty stomach, but they feel like vomiting. What's the matter?
Exercise on an empty stomach will lead to insufficient heat supply, prone to hypoglycemia, resulting in nausea, vomiting, dizziness and other discomfort.
Note: before exercise, you can properly eat some foods that are easy to digest, such as bananas. If you are a patient with hypoglycemia, you can carry sugar lumps with you and supplement them in time when you feel dizzy, nausea and vomiting.
lack of water
During fasting exercise, a large number of nitrogen-containing wastes and ketones will be produced in the body. In order to discharge these wastes out of the body, the body will further produce urine and increase the excretion of urine, resulting in dehydration. At this time, the body is in the crisis of lack of energy and water, and there will be dizziness and vomiting.
Note: appropriate water should be added during exercise. After exercise, some light salt water should be added in time to supplement the lost inorganic salt.
blood pressure disease
If people have hypotension or hypertension, they are prone to nausea, dizziness and vomiting after exercise, let alone fasting exercise
If the blood pressure is too low, the blood supply to the brain is even less after exercise, resulting in dizziness and vomiting. If the blood pressure is too high, then strenuous exercise will lead to further increase of blood pressure, pressure on blood vessels and discomfort.
Note: people with blood pressure diseases should monitor their blood pressure at any time, exercise appropriately, and do not exercise on an empty stomach.
too much exercise
When the amount of fasting exercise is too large, the brain will automatically allocate energy and resources to the exercise system and muscles, and slow down or stop the systems unrelated to exercise. The digestive system is one of them. The stomach food lacks energy to decompose and absorb it. When the amount of exercise is large and lasting, this part of the food will be regarded as a burden, and then vomit out by stimulating the gastric nerve.
Note: adjust the exercise intensity so that the body will not produce discomfort.
When running in cold weather, cold air is easy to be sucked into the stomach, which is quite irritating to the intestines and stomach. After the human stomach gets cold, it will produce spasm and make the gastric juice turn up, resulting in nausea and vomiting.
Note: it is recommended not to breathe with your mouth, but with your nose.
other disease factors
People with anemia, cold, gastritis, chronic rhinitis and other diseases are also prone to dizziness, nausea, vomiting and other symptoms during fasting exercise.
Note: if it is caused by disease factors, seek medical examination in time.
What should we pay attention to in sports diet
Exercise should not be carried out on an empty stomach. It is best to eat some food and supplement energy 2 hours before exercise, but remember not to exercise immediately after eating. This will also lead to nausea, because during exercise, most of the energy of the body is used to participate in exercise, and the peristaltic digestion of the intestines and stomach will slow down or even stop. If there is much food residue in the stomach, It is easy to make the human body vomit; Therefore, it is the best practice to exercise 2 hours after eating.
