Hypothyroidism (cont.)
What are the symptoms of hypothyroidism?
The symptoms of hypothyroidism are often subtle. They are not specific (which means
they can mimic the symptoms of many other conditions) and are often attributed
to aging. Patients with mild hypothyroidism may have no signs or symptoms. The symptoms
generally become more obvious as the condition worsens and the majority of these complaints
are related to a metabolic slowing of the body. Common symptoms are listed below:
As the disease becomes more severe, there may be puffiness around the eyes, a slowing
of the heart rate, a drop in body temperature, and heart failure. In its most
profound form, severe hypothyroidism may lead to a life-threatening coma (myxedema coma). In a
severely hypothyroid individual, a myxedema coma tends to be triggered by severe illness,
surgery, stress, or traumatic injury. This condition requires hospitalization and immediate
treatment with thyroid hormones given by injection.
Properly diagnosed, hypothyroidism can be easily and completely treated with thyroid
hormone replacement. On the other hand, untreated hypothyroidism can lead to an
enlarged heart (cardiomyopathy), worsening heart failure, and an accumulation of fluid around
the lungs (pleural effusion).
