Can heartburn induce asthma attacks?

I once heard that some people with acid reflux can also trigger some asthma attacks, is that possible?

Yes, heartburn, (acid reflux disease (GERD) (or hiatal hernia)) can trigger and even cause asthma, certainly make it worse.

GERD is caused by a genetic predisposition resulting in a weak
valve between the stomach entrance and the esophagus.

Stomach acid fumes, hydrochloric acid fumes, and even the
stomach acids themselves travel up the esophagus and can
enter the bronchial tree.

This can cause discomfort for anyone and can trigger or worsen
asthma.

There is a rule, not everyone who has GERD has asthma, but
a majority of people who have asthma have GERD.

Raise the head of your bed by 6 inches, use old phone books.
Don't eat after 7 PM.
Keep your weight down and your stomach muscles firm; firm
stomach muscles sort of act as an external valve to help the
internal valve that is not closing.

See a GI specialist, who will do down your esophagus with a
tube, check your esophagus for erosion and your stomach for
ulcers; you really NEED to do this rather than just use the
acid suppressing drugs only.

After the GI specialist determines no ulcers, start using
Prevacid or Nexxium each morning before eating and if needed
for a few months, at 8 PM.

Get treating the asthma symptoms with asthma drugs.

Go to a quality pulmonologyst for the asthma and then a
family doctor; develop a close and continual relationship with both of them; your asthma can get much better, but it usually
does not go away, and you need good continual treatment by
2 wise doctors regularly.

Get annual flu shots, a pneumonia shot, walk for exercise eat healthy, stay away from all smoke and fumes.

You can actually have a very happy and fullfilling life with asthma.

Yes. And it sucks. Neither one is fun, but both is a double-whammy.

Also cold can trigger it (ice cream, cold weather), and bad "ozone" days/hazy conditions.

Yes - one can trigger the other. I have acid reflux, I don't get asthma attacks but I have trouble breathing sometimes.
