Patient: Hello, Dr. Zhi! Since April of this year, I have been experiencing frequent allergies after performing strenuous exercise with a hot body (but not when doing strength training, such as barbells, etc.). When I have an allergy, the rash first appears on the hotter parts of my body, then spreads to my whole body, and the rash is very large and numerous, and soon becomes one side, and the skin of my body is large and swollen. The rash is the same color as the skin, and if the skin is tightened with force, the rash is white and the surrounding skin is red. After about half an hour or so, the rash ceased, but the drop in blood pressure was severe, and shock and fainting occurred several times. In the last month, this condition appeared after strenuous exercise and anemia. However, it usually never occurs. I’ve been to the hospital and my blood pressure is very low, 40/70. Can Dr. Zhi explain to me why I have frequent allergies. Is it related to the fact that I have been doing strength exercises a lot this year? Is it because my physical condition has deteriorated? Can this disease be cured, or how can I reduce the chances of developing it? Yuxiang Zhi: You have to come to the doctor to clarify the cause of the disease in order to treat it. But if it is clear that it is related to exercise, the best prevention is to reduce exercise. Also, pay attention to whether you have allergies after eating a meal and exercising, because some allergies are food-dependent exercise-induced allergies. Pay attention to whether you have symptoms after eating certain foods and exercising, and come to Beijing for consultation at your convenience.
