Patient discussion about trigger.

Q. How do you prevent an asthmatic attack from re-occurring? I am very anxious about having another asthmatic attack, because this doesn’t happen very often. How can I make sure I avoid having it?

A. reflexology. that's what helps me. have you tried alternative medicine before? as the asthma is only an outcome of something deeper- medication are usually more a treatment then a prevention. try reflexology treatment-it can help prevent another attack- maybe even make it never come back.

Q. What is the ingredient in perfume or Cologne that will trigger an asthma attack? There is something in cologne/perfume that's not in body spray that triggers my asthma. I went out with a friend and he had on cologne and my asthma starting bothering me. Before going out my asthma hadn't bothered me in months because I stay away from things that may trigger an attack. This often happens with other things like bleach, ajax or any bad odor

A. Anything that irritates the nose and bronchi can cause an attack. No one really knows why...but it does. Cigarettes and pollution are common cause also.

Q. how can these trigger his episodes and what exactly has happened to him? My son is a bipolar patient. We took him to the doctor as his manic episode has started again. This episode was a high one as compared to his previous episodes. Previous episodes used to get triggered due to his work related stress. He keeps himself in routine which makes his life comfortable. Recently he went on a vacation with his colleagues. Once he was back I found his condition was worse and soon his episodes started again. His regular medicines were not of any help. So I took him to the doctor. His medicines were not changed except a new one was added. Doctor had told to reduce on any stress as much as possible. Strictly he has been told to reduce on anything which triggers stress like coffee, tea, high sugar intake, on cigarettes as well. How can these trigger his episodes and what exactly has happened to him?

A. I am not sure how they trigger the manic episodes as I have not gone through any research indicating any clear reasons to me. But I am sure on the lines of personal experiences with my bipolar daughter that they do trigger her episodes. Especially when she is short of sleep her manic episodes starts. Medicines help her keep calm and to get good sleep. I feel that your son didn’t get the required amount of sleep due to his vacations or would have stressed himself on a high scale. His medicines were also not benefitting him…may be he could have missed on his medicines. Just take care of him and help him avoid all triggers.
