<s>[INST] How many calories would I burn in an asthma attack? I'm trying to lose weight, but this morning when I went running in the cold, I had a mild attack. I didn't have my inhaler on me, so had to walk back home. I'm just curious to know if the attack burned any calories for me. [/INST] HI, thanks for using healthcare magicAny illness , including asthma, causes a temporary increase in metabolic rate and as a result causing calorie expenditure but the exact value is not known.It is not likely to be a significant amount since it for a short mild attack.You may want consider the use of your reliever inhalor prior to exercise to decrease the chance of an exercise induced attack.I hope this helps </s>
