Is Underactive Thyroid Treatable?

Underactive thyroid, or hypothyroidism, is common and in most cases treatable.

NP Thyroid may be prescribed to replace low levels of triiodothyronine (T3) and thyroxine (T4). Other indications: manage thyroid cancer, thyroid nodules, prevent and treat goiter. It is not prescribed for temporary, or transient, hypothyroidism.

NP Thyroid is derived from desiccated porcine thyroid. It is considered a natural source of the hormone rather than synthetic, or “man-made.”

In conjuction with NP Thyroid, your doctor may advise you to change your diet and suggest an exercise program to improve your thyroid function.

What Are T3 And T4?

T3 and T4 are hormones produced by the thyroid from the amino acid tyrosine. They play a central role in temperature regulation, heart rate, and brain development and function. T3 is especially linked to the regulation of bone and digestive heath.

T4 is a precursor to T3, which means that T3 is synthesized from T4.

Your cells produce most of the tyrosine in the body by taking positive ions (protons) from iodine, a process known as deiodination—hence, the reason why iodine is essential for thyroid health.

Free T4 VS Bound T4

On its own T4 is inactive but it is essential for the production of T3. However, more than 90% of T4 produced by the thyroid becomes unusable because it attaches to proteins that prevent it from entering tissues.

The amount of non-bound T4 is called free T4. It enters tissues and is then converted by cells into T3 to carry out physiological functions and maintain health.

What Are Symptoms Of Hypothyroidism?

• Weight gain
• Sluggishness
• Constipation
• Depression
• Muscle cramps
• Sensitivity to cold
• Dry or itchy skin

What Causes Underactive Thyroid?

The most common cause of hypothyroidism is Hashimoto’s thyroiditis. It is an autoimmune disease that causes the immune system to attack the thyroid gland and inhibit its production of T4 and T3.

Is Hypothyroidism More Common In Women Than Men?

Yes, women are more likely to have underactive thyroid than men.¹ In fact, women are more likely than men to have any type of thyroid dysfunction.²

It is estimated that 20 million American have thyroid disorders and less than half are aware of their condition.³

People over the age of 60 are at higher risk for hypothyroidism and hyperthyroidism.^1,2

What Is Goiter?

Goiter is an enlargement of the thyroid hormone. It may be caused by hypothyroidism, hyperthyroidism or lack of iodine in the diet. It may not impact thyroid function but can be uncomfortable or make it difficult to swallow. Goiters can be benign or cancerous.
