Euthyroidism of the thyroid, what is it? Symptoms and treatment of euthyroidism

Euthyroidism is a condition bordering on a serious pathology of the thyroid gland.

Diseases of the thyroid gland - a common pathology, affecting the functioning of the body as a whole. Thus not always the analysis on hormones Т3, ТТГ and Т4 can find out disease. Such a pathological condition, in which the hormonal level remains normal, is euthyroidism.

Against the background of euthyroidism, a person can develop more severe pathologies, leading to irreversible changes in the thyroid gland. What is thyroid euthyroidism, is it dangerous and how to treat it? Everyone who cares about his health should know this.


Euthyroidism - what is it?


Euthyroidism of the thyroid gland is a reversible change in the structure of the organ while maintaining its functionality. The symptomatic picture of euthyroid pathology excludes signs of hypothyroidism or hyperthyroidism .

Despite the fact that the thyroid gland reveals the proliferation of its tissues in the form of a diffuse increase or nodes, the hormones remain normal. . However, this does not mean that the person is completely healthy .

Euthyroidism is a borderline condition in which the level of hormones at any time can change upwards or downwards.

The euthyroid state lasts a short time. Usually, on its background, more rapid changes occur, accompanied by hypo- or hyperfunctionality of the thyroid gland. That is why the timely detection and treatment of euthyroidism is so important.

The etiology of euthyroidism is the main cause

The thyroid gland is very sensitive to all kinds of changes (both external and internal). Euthyroidism can be triggered by the following factors:

  • deficiency of iodine supplied to the body with food;
  • hereditary predisposition;
  • adverse environmental factors;
  • inflammatory pathology of the gland;
  • nervous breakdowns, stress;
  • autoimmune thyroiditis (euthyroidism, as the initial stage of autoimmune inflammation of the gland, can last for years).

Euthyroid status can be documented in pregnant women with previously diagnosed hyperthyroidism. normalization of the hormonal level during pregnancy occurs due to an increase in the body's need for thyroid hormones.

If the physiological decline in the hormonal level does not occur, doctors resort to medical therapy. The normalization of hormonal parameters directly depends on the preservation of pregnancy and the birth of a healthy child.

That is why it is so important to achieve drug-induced euthyroidism during pregnancy in women who suffer from increased thyroid function.

Classification of euthyroidism

In terms of severity of pathological changes, endocrinologists distinguish between euthyroidism:

  1. 1 degree - the enlargement of the gland is not determined visually, palpation also does not reveal abnormalities;
  2. 2 degrees - visually noticeable enlargement of the gland, but palpation does not work;
  3. 3 degree - an increase in thyroid tissue is noticeable on examination and is confirmed by palpation.

Nodular goiter with euthyroidism

Nodular goiter with euthyroidism

The euthyroidism provoked by a lack of iodine is accompanied by a nodal goiter: diffuse growth of the thyroid gland and the formation of single or multiple nodes. Depending on the nature of the structural changes, several forms of nodular goiter are considered in euthyroidism:

  • diffuse increase without nodal inclusions;
  • identified single node;
  • detected multiple sites;
  • multiple nodes that merge with each other.

Symptoms of thyroid euthyroidism

The nervous system is the most responsive to euthyroidism. To suspect abnormalities associated with the thyroid gland, you can by the following symptoms:

  1. Rest in normal mode or normal sleep does not give the desired result. A person feels defeated, notes a growing weakness without reason. There is insomnia at night and drowsiness during the day.
  2. Acute reaction to stimuli. Even a minimal discontent can develop into a major quarrel. In this case, a person suffering from euthyroidism is not only emotionally unstable, but also recovers from stormy experiences for a long time.

The increased excitability of the nervous system is accompanied by symptoms associated with the work of other organs and systems:

  • Neck - there is a lump in the throat that makes it difficult to swallow, periodically or constantly the patient feels neck compression (a feeling similar to strangulation from the rope around his neck);
  • Heart - various violations of the rhythm of heartbeats from tachycardia (rapid heartbeat) to extrasystoles (extraordinary heart beats);
  • Weight - for euthyroidism is characterized by a decrease in body weight for no apparent reason (against the background of the usual diet, without diet, in the absence of severe diseases of other organs).

The patient or doctor, when referring to the clinic, can visually or palpatorically enlarge the size of the gland and nodal inclusions. However, it is necessary to confirm the structural changes with the help of ultrasound. Also to confirm the diagnosis is mandatory and the analysis for thyroid hormones.

Normal hormonal indicators, together with an increase in the gland or the detection of nodes / cysts, are confirmation of the euthyroid state. To differentiate euthyroidism from oncology, it is advisable to perform scintigraphy and biopsy of suspicious nodes.

Treatment of thyroid euthyroidism

Treatment of thyroid euthyroidism

Euthyroid status does not always require medical treatment. Thus, with a slight diffuse change in the thyroid gland and 1-2 nodes up to 0.8 cm in diameter (for example, in autoimmune euthyroidism), endocrinologists recommend only active observation: 1 every 6 months. should undergo an ultrasound examination of the thyroid gland.

For a patient wishing to maintain their health, such a tactic will not cause difficulties: ultrasound is available in terms of cost.

If a patient has severe structural changes in the thyroid tissue in the presence of severe symptoms, a course of medication is prescribed.

  • To normalize the patient's condition and, at least, to stop the growth of tissues, iodine preparations (Microroyod, Camphodal, Antistrum and others) or L-thyroxine (Levothyroxine) are prescribed.

Dosages of drugs are determined individually. If there is no result of monotherapy, it is possible to prescribe a combination of Levothyroskin and iodine-containing drugs.

Control ultrasound is performed every 3-6 months, after which the treatment regimen can be adjusted. A good result of treatment is the elimination of disturbing patients with euthyroid symptoms and the absence of further tissue increase.

With effective treatment with time, the thyroid gland comes to normal: the nodes disappear or decrease (0.8 mm or less), and the regression of diffuse proliferation is noticeable.

Operation with euthyroidism

In the absence of a minimal therapeutic effect (stabilization of the condition) from drug therapy, the endocrinologist can offer a surgical intervention.

The operation implies minimal excision of pathological elements (growing nodes) and partial resection of diffusely expanded tissue.

Now, such operations are performed by endoscopic access through mini-cuts. These results in minimal tissue trauma, which results in a short period of hospitalization (2-3 days) and rapid recovery. This achieves an excellent cosmetic effect: on the neck there are only barely noticeable little scars.

The complexity of the operation with euthyroidism is that it is necessary to accurately determine the volume of excised tissue. Excessive excision can lead to postoperative hypothyroidism, and insufficient will not give the necessary therapeutic effect. Therefore, for carrying out such a surgical intervention, one should only apply to an experienced endocrinologist-surgeon.


Timely treatment of euthyroidism gives a favorable prognosis. Minor changes in the structure of the thyroid gland can independently be eliminated when correcting the lifestyle: full nutrition, healthy sleep and rest, maintaining emotional stability.

When the drug is applied in a sufficient dose (regular intake of medications prescribed by the doctor is required!), The pathological changes gradually regress.

The greatest danger is eutyroidism untreated or actively progressing against the background of drug treatment. In such cases, the risk of rapid development of irreversible changes in the thyroid gland and the violation of hormonal parameters are high.

In such cases, more serious therapy with hormones (with hypothyroidism) or their antagonists (with hyperthyroidism) is required.
