Laryngospasms can be caused by GERD and damage to the vocasl chord nerves.
In my case these did't apply....

About 3 years ago I had suffered 3 Laryngospasms within 18 months,
the last 2 within 6 weeks of each other, (when I was referred to a specialist.)

The specialist said my Laryngospasms could be caused by my goitre and the only advice given was to try to breath in slowly during attacks.

After this I soon found on the internet that Calcium deficiency can case muscle spasms so I asked my Doctor to check my Calcium level. It was OK.
But as a precaution I started to take Calcium anyway....taking just 1/2 of RDA.

Very fortunately for me, the supplement bought from a health shop, in addition to Vit D, contained Magnesium, Copper, Boron and Zinc too.

I had no further attacks for nearly 3 years........

But after about 2 1/2 years I began to purchase most of my supplement in supermarkets.
This only contained Calcium and Vit D.

Approx. 4 months after using mostly the supermarket supplement I had 3 very slight short attacks within about a 4 week period. Foolishly, I ignored them.
5 days after that third attack I had a full Laryngospasm on 15/1/09.

Immediately I returned to taking my original supplement containing Magnesium etc.
I have not suffered any further Laryngospasms.

Magnesium is a muscle relaxant and has been used to prevent
Laryngospams in children during operations on the throat.


The RDA for Magnesium for a man over 35 is 420 mg.
The foods containing the most Magnesium are not those eaten every day,
or at all by many !
So for me, to absorb 420mg per day could be quite a task, especially as I drink a great deal of tea as the sole Calcium in milk can deplete the body's Magnesium.

I now believe that my voice box muscles are relaxed just by simply taking 1/2 RDA of Magnesium. Magnesium deficiency can cause muscle spasms and cramp and although I may not be deficient, that little extra is relaxing my vocal chords and so prevents attacks. The copper, boron or zinc too my assist in this.

Of course, this may not work for others and the taking this supplement which appears to cure my Laryngospasms could be the placebo effect. But I think not.
I hope all this may help other sufferers of this frightening disease.
