Can you tell me, are mild asthmatics at risk for asthma attacks?

Yes: All asthmatics are at risk for severe asthma attacks. Unfortunately being a mild asthmatic does not preclude one from have a severe asthma flare.

Yes: Depends on how well controlled you are and what meds your on. Severity of asthma is determined by use of meds and frequency of attacks also what are your triggers for the attack. Viral illness the most common cause followed by noxious stimuli. The meds include a inhaled steroid and a beta agonist(rescue inhaler). Multiple factor involved but yes you may be more susceptible to attacks. Try act test.
