Hypothyroidism: symptoms, treatment, diagnosis,the reasons

Обновление: Декабрь 201eight

During life, each of us faced fatigue,
сонливостью, слабостью, которые возникали без явной the reasons.
Maybe, они были связаны со стрессом, недостаточным количеством
sleep, poor nutrition and many other everyday
factors. However, if the above symptoms become
constant companions of your life is a reason to suspect

WITHуществует несколько форм этого заболевания, каждая из которых
has its own characteristics. Some of them flow without bright
expressed symptoms, which is why patients seek medical attention
help only in the later stages of the process. In different regions
Russia, the incidence of the disease ranges from 2.5% to 20%
from the entire population.

Withчины и классификация

Каждая форма заболевания имеет свои the reasons, которые достаточно
are specific. Currently, clinicians identify 2 main
species and 5 subtypes of hypothyroidism. Thanks to the research
Scientists have distributed provocative factors according to the classification
in the following way:

  • Congenital – this form is rarely familial, more often
    there are isolated cases. They are due to a gene mutation
    responsible for the formation of the thyroid gland, or congenital
    vice of this body. Developmental anomaly may occur due to
    various factors (smoking or drinking mother,
    infections during pregnancy). WITHтарое название детского
    hypothyroidism – cretinism, but now it has been removed from the international
    classification of diseases of the tenth revision. Currently,
    they are used only by patanatoms.
  • Withобретенный – может возникать как до 1eight лет, так и в зрелом
    age Adult hypothyroidism is termed myxedema.

  • taking certain medications (for example, Tiamazole);
  • surgery (removal of part of the gland – resection);
  • tumors (adenoma or cancer), metastases from other organs;
  • lack of iodine or violation of its absorption (often
    after removing a large portion of the small intestine).

Despite the large number of forms of hypothyroidism, the symptoms
fundamentally different in only two types: child

active human process is complete without thyroxin and
triiodothyronine. They are necessary for normal thinking, work

Withзнаки у детей

In childhood, a huge amount of body energy goes away
on growth and thought processes. Therefore, the main symptoms
hypothyroidism in children is:

  • Delayed physical development, which is accompanied by
    insufficiency of internal organs (most often of the heart, liver,

    emotional sphere, but also other functions of the cerebral cortex
    (reading, counting, writing, self-awareness in space, memorization

    this leads to idiocy;
  • Goiter – as usual cell count produces

    and enlarges the thyroid gland in size. This is achieved by
    выработки hormoneов hypothalamus (тиреотропного). Unfortunately,
    organ proliferation rarely causes symptoms to disappear.

In adults, energy distribution occurs somewhat differently.
Since the organism, including the brain, is already formed,
the main reserves of glucose go to maintain normal
life activity: physical, mental activity, adaptation to
stress, adequate work of internal organs. With гипотиреозе
all these processes are violated. Symptoms related to
damage to the following body systems:

  • Nervous – most nerves and bark consume most glucose
    big brain, that’s why they start to suffer first.
    The lack of function of the nervous system is manifested: drowsiness,
    lethargy, forgetfulness, frequent depression, apathy,
    volatility to stress. In later stages may

    paresthesias are possible (crawling, tingling sensations),
    slow speech, as if “tongue braids”;

    medium intensity; at rest decreases but does not pass until
    the end; nitroglycerin has no effect), anemia, headache
  • Digestive – characterized by decreased appetite, delayed stool
    (more than 3 days), nausea, diarrhea are possible (as it is broken
    absorption and intestinal motility), flatulence, liver enlargement,
    biliary dyskinesia;
  • Muscular – severe weakness, muscle pain (due to a decrease in
    glucose levels, lactic acid builds up and irritates
    pain receptors), in the later stages – hypo- / atrophy;

Inadequate therapy or late diagnosis on the background
severe hypothyroidism can lead to “hypothyroid coma”:

decrease below 1 nmol / l).
Norm — 70,3-204,4 нг% (1,0eight-3,14 нмоль/л)
ТТГ (тиреотропный hormone гипофиза) allows you to determine the type: primary or secondary. AT the first
case, the level increases significantly, with secondary –
going down.
Norm – 0.4-4.2 µMU / ml
AT-TG (antibodies to thyroglobulin) using this analysis confirm primary hypothyroidism due to
autoimmune inflammation. An increase indicates the presence of

The disadvantage of these instrumental methods is that they
do not allow to evaluate the function of the thyroid gland. For this
there is an additional paid study – radioisotope

clinical trials have not been identified – the procedure
безопасна для the patient.


How to prepare for scintigraphy?

For better quality research, diagnosticians recommend
cancel iodine preparations 30 days before the examination. But,
you need to consult a doctor who decides whether
do it. Three months before scintigraphy should not be carried out
X-ray contrast studies
(vascular angiography, urography, pancreatography).

Most often, the changes are absent or mild


Depending on the diagnosis, the doctor is determined with
tactics and subsequent treatment. Doctors endocrinologists do not recommend
conduct therapy to patients in the following conditions:

  • transient or peripheral hypothyroidism, without pronounced
  • subclinical hypothyroidism, if TSH is less than 4.2 µMU / ml.

In other cases, it is necessary to carry out adequate treatment. With
All forms of the disease are prescribed replacement therapy, which
allows you to eliminate the symptoms of thyroid failure.

Tireoto, Tireoto-forte). Otherwise, the treatment will not bring
no effect.

Prescribing iodine preparations is not necessary (in accordance with
MES), therefore the doctor should solve this question individually. With
the appearance of edema, it is recommended to take diuretic drugs in small
doses (Lasix, Furosemide). Severe depression is a reason for
prescription of sedatives (Persen, Corvalol,

Therapy is considered successful if the amount of TSH lies within
0.5-2.0 µIU / ml.

If the patient does not seek medical help, the symptoms may
quickly progress and lead to hypothyroid coma and
of death.


How effective are hormones for hypothyroidism?

Their effectiveness has been proven in clinical trials for all.
forms of hypothyroidism, except peripheral. However combined
therapy together with iodine preparations, as a rule, has
positive effect.

Will I have a goiter?

Its formation is possible only in the primary form due to
elevated TSH levels. With своевременном лечении этого легко
to avoid.

Will I be able to completely get rid of this disease?

Only from the transient form – its symptoms go away within 6
months. In all other cases, the patient is forced for life.

Can I eat a lot of sweet?

Excessive consumption of flour, sweet or fatty foods may
quickly приводить к ожирению. Therefore it is better to limit
consumption of these products to reasonable limits (pastry shops
изделий не более ten0-150 г в день).

What popular treatment is most effective?

Clinically proven and effective treatments for hypothyroidism
folk remedies are not.

How often should an endocrinologist visit?

Without обострений, не реже чем один раз в шесть

What are the complications after taking hormones?

There are many of them (increased heart rate, pain in the area
