Low Thyroid

Low Thyroid function is also known as hypothyroidism and is the most common thyroid problem. This means that the thyroid gland is underactive, failing to produce an adequate level of thyroid hormone. Since thyroid hormone regulates metabolism, a lack of thyroid hormone causes the metabolism to slow down. This often results in a long list of negative health effects, including:

• tiredness
• weakness
• intolerance of cold
• weight gain
• constipation
• depression
• irritability
• dry skin
• dry hair
• hair loss
• aching muscles
•  increased menstrual flow
• reduced heart rate
• forgetfulness and confusion

Hypothyroidism is primarily caused by Hashimoto's thyroiditis in Western adults. This happens when the body produces antibodies that attack and over time destroy the thyroid gland. Women are 8 times more likely to develop this condition, especially when they grow older. The condition may run in families, or be associated with genetic conditions. Another cause can be the treatment of an overactive thyroid gland (hyperthyroidism).

In developing countries, iodine deficiency is a major cause of hypothyroidism. Because iodine is added to many common foods in Western countries, this cause is extremely rare in the West.

If hypothyroidism is left untreated, sometimes an extreme form will develop called myxedema. This can result in anemia, congestive heart failure, and coma.

The typical treatment for hypothyroidism is administering a synthetic form of thyroid hormone called thyroxine. High doses can have a severe effect on the health of seniors. Usually, the dose is adjusted according to the deficiency until hormone levels return to normal. There are also some natural herbal hypothyroidism treatments available that may be used in conjunction with thyroid hormone. Hypothyroidism usually gets worse over time, so even mild cases should be treated.

If you suspect you may have hypothyroidism, it is best to consult your doctor. Your doctor can run blood or iodine tests to determine if in fact you do have a deficiency of thyroid hormone and if so, begin the treatment.
