"The most common cause of hypothyroidism is Hashimoto's thyroiditis".

What is Hashimoto's tiroiditis?
Hashimoto's thyroiditis is a clinical picture that results from reduced activity of the thyroid gland. The thyroid hormones (T4 and T3), whose synthesis is regulated by the TSH secreted in the pituitary gland, have the fundamental mission of regulating the body's metabolic reactions.
When the thyroid hormones diminish, as it happens in the hypothyroidism, the secretion of TSH increases in an attempt to get the thyroid to work to the maximum to recover the normal level of thyroid hormones, situation that does not obtain when the hypothyroidism is established.
Consequently, hypothyroidism is characterized by an overall decrease in organic activity that affects metabolic, neuronal, cardiocirculatory and digestive functions, etc.

What are the symptoms of Hashimoto's Thyroiditis?
The establishment is usually slow and progressive. The symptoms are related to a decrease in the functional activity of all the systems of the organism.
The most classic are fatigue, intolerance to cold (very cold character), apathy and indifference, depression, decreased memory and mental concentration capacity, dry skin, dry and brittle hair, nail fragility, skin pallor, weight gain, stubborn constipation and excessive sleepiness.
In extreme situations it can evolve into heart failure, generalized swelling (myxedema), respiratory failure and lead to myxedema coma with loss of consciousness leading to high mortality.

The most common symptoms are:
- Intolerance to cold.
- Apathy and indifference.
- Dry skin, dry and brittle hair.
- Weight gain.
- Overall decrease in organic activity.
Do you have any of these symptoms?
You may have Hashimoto's Thyroiditis
What are the causes of Hashimoto's Thyroiditis?
The most common cause of hypothyroidism is Hashimoto's thyroiditis which results in progressive destruction of the thyroid as a consequence of autoimmunity phenomena. It is as if the organism does not recognize the thyroid as its own, so it proceeds to its destruction by means of antibodies produced by the immune system.
This condition is especially frequent in the female sex from the age of 40, although it can occur at other ages and in males.
Who can suffer from it?
Like other thyroid diseases, hypothyroidism is more common in women. It is from the age of 40-50 when women tend to develop more frequently hypothyroidism of autoimmune cause (Hashimoto's thyroiditis). The postpartum period is also prone to the appearance of this problem.
Thyroid surgery and the application of radioactive iodine represent risk situations for the development of hypothyroidism, which forces the evolutionary control of thyroid function in these cases.newborns of hyperthyroid mothers, whether or not they have received antithyroid treatment during gestation, should be evaluated in this regard.
People in whom antithyroid antibodies (antimicrosomal, antithyroglobulin) are detected tend to develop alterations in thyroid function over time, so they should be evaluated chronically on a regular basis.
What is your prognosis?
Under adequate substitution treatment, the quality and life expectancy of hypothyroid patients is not restricted in any way.
How is Hashimoto's Thyroiditis diagnosed?
The determination of TSH is the most sensitive parameter for the diagnosis of hypothyroidism. Its elevation is indicative of insufficient thyroid function. This phenomenon occurs before the concentrations of thyroid hormones begin to drop in the blood.
Generally, in the established hypothyroidism, in addition to the elevation of TSH, a decrease of T4 is produced. The level of T3 is often within normal range. It can be accompanied by a determination of T4 and antithyroid antibodies if it is desired to know if the cause is due to autoimmunity phenomena.
If there is goiter, it may be convenient to perform a thyroid ultrasound.
When there is suspicion of alterations in the development of the gland or of enzymatic deficiency, it can be useful to obtain a thyroid scan. If a diagnosis of autoimmune hypothyroidism is confirmed, it is usual to evaluate the association of alterations in other glands such as the adrenal, parathyroid or gonads.
How is Hashimoto's Thyroiditis treated?
The treatment of hypothyroidism consists of replacing the production of the thyroid gland. The most stable and effective way to achieve this is to administer thyroxine (T4), as it has a long life and in the body it is partly transformed into T3, so it is not necessary to replace this last hormone.
There are commercial preparations containing 50 or 100 micrograms per tablet. The dose is administered orally once a day on an empty stomach. Once the appropriate dose has been established by the physician, the controls that allow the adjustment are based on the clinical evaluation and the determination of T4 and TSH.
With few exceptions, established primary hypothyroidism is a chronic condition, requiring lifelong treatment. However, with the right dose, hypothyroid patients have no limitation in their activities.
Myxedema coma requires treatment in the Intensive Care Unit.
Where do we treat it?
IN NAVARRA AND MADRID
The Thyroid Pathology Area
of the Clínica Universidad de Navarra
The Thyroid Pathology Area is made up of a multidisciplinary team of specialists who work together to offer patients with thyroid problems an accurate diagnosis.
After the diagnosis, the patient is indicated the most appropriate treatment for his or her case and a continuous follow-up is carried out to achieve the desired objectives.
The Clinic is a pioneer in the implementation of medical techniques in Spain and worldwide, and is an international reference in highly specialized procedures.
Why at the Clinica?
- Prestigious professionals who are a national reference.
- In 24-48 hours we make the diagnosis and we can start the most appropriate treatment for each patient.
