Hashimoto's is an auto-immune disorder in which the thyroid gland is
attacked and as a result it's production of thyroid hormone decreases.

Since thyroid hormone is the "spark-plug" of metabolism, a deficiency
of it has many effects.  Curiously, many people who are diagnosed with
Hashimoto's were previously diagnosed as asthmatic, and almost invariably
when the thyroid disorder is treated the symptoms of asthma either stop
or greatly diminish.  No formal studies have been done to confirm or deny
a link -- but it appears that for many people asthma is a symptom of
marginal or undiagnosed hypothyroidism.

Perhaps some day we will have definite answers about the questions
of thyroid - asthma connections.  For now all we have is speculation.

However, it is worth keeping in mind that there may be a connection,
and make sure that thyroid function is tested at least every few years
if you have been diagnosed as having asthma.
