Dr. Zhai from the Emergency Department of Shanghai Tongren Hospital has issued a blood and tear advice for nine years of medical practice: If you experience these symptoms after exercise - large itching, urticaria (commonly known as rubella lumps), and sudden fatigue, you can no longer persist!!!

Why, why?

Dr. Zhai: Exercise allergy!

Case sharing - What are the manifestations of "exercise allergy" and "exercise allergy"?

In early April, a young man in his thirties came to the emergency department, wearing a mask and shyly asking, "Doctor, can you see this allergy? I have already taken a pill of Kairuitan." Dr. Zhai looked up and saw that the boy's face, which was exposed from the edge of the mask, was heavily flushed, and his arms were covered in obvious papules.

What did you eat.

No food, I'm running! That's all after running

Have you ever had it before

Yes, there have been several runs where I have had rashes. However, this time it was particularly common and did not subside for a long time. Additionally, I felt a lot of chest tightness

Further examination revealed that the young man's blood pressure was 90/60 mmHg low, and his heart rate increased by 110 beats per minute, which was quite serious. Exercise allergy! Dr. Zhai immediately made a judgment, and there were already symptoms of allergic shock. The young man was immediately sent to the emergency room for treatment such as allergy resistance, fluid replacement, and volume expansion. Soon, chest tightness, shortness of breath symptoms relieved, and the rash subsided. It really comes and goes quickly, which is very consistent with the manifestation of allergic diseases! If it weren't for the young man seeking medical attention in a timely manner, the consequences would be unimaginable.

Unveiling the mysterious veil of "exercise allergy", the full name of "exercise allergy" is a systemic allergic reaction induced by exercise, which only occurs during exercise and can manifest symptoms at any stage of exercise.

The pathogenesis of "exercise allergy" is known to be degranulation of skin mast cells and transient elevation of plasma histamine and serum trypsin levels. Some patients have food dependence, which means that symptoms only appear when exercising within a few hours after eating, and most patients eat specific foods. Although exercise is an immediate trigger factor, many patients are more likely to experience symptoms when accompanied by one or more of the following synergistic factors.

These factors include:

Take non steroidal anti-inflammatory drugs such as aspirin, paracetamol, ibuprofen, etc.

● Alcoholic beverages

● The premenstrual or ovulatory period of a woman's menstrual cycle

● Extreme temperature (exposure to high temperature, humidity, or cold)

Seasonal pollen exposure in patients with pollen allergy

Persistent infection or other diseases can have serious consequences such as increased skin temperature, flushing, widespread itching, urticaria, and sudden fatigue, which are only early symptoms.

If, at this point, you decide to persist with strong perseverance, then there is a possibility that the next step will be:

● Vascular edema of the face and/or limbs (usually hands), also known as giant urticaria, is a localized swelling of a certain part of the body caused by allergies

● Gastrointestinal symptoms: including nausea, abdominal cramps, and diarrhea

● Laryngeal edema (congestion and edema of the laryngeal mucosa)

Low blood pressure and/or circulatory failure (reduced systemic blood flow, leading to ischemia and hypoxia of important organs) can occur in a very small number of patients with allergic shock, such as bronchospasm and headache. Stopping exercise can also alleviate the symptoms. However, since it is an allergic change, it is necessary to prevent the serious consequences of allergies - shock or sudden death.

If you have any unusual discomfort, please stop first. Dr. Zhai reminds you that it is terrifying that many patients with exercise allergies are unaware of this condition, and some may overcome the discomfort and choose to exercise; Some people will run to seek help. These are all wrong! If the above symptoms occur, please do not pay attention to the eyes of others. Remember to stop exercising! After the symptoms have relieved, it is also important to remind oneself that when choosing sports in the future, one should also be cautious, and be even more cautious! With the improvement of the COVID-19, many people resumed physical exercise. While strengthening your body, don't forget to pay attention to your physical abnormalities. If you have symptoms such as rash and itching, please stop exercising immediately and drink plenty of water. For mild symptoms, you can take anti allergic drugs such as loratadine on your own. However, if chest tightness, shortness of breath, dizziness, etc. cannot be recovered after rest, it is necessary to go to the nearest hospital for treatment. In short: Understand yourself and act within your capabilities!
