Hiper si hipotiroidie

examen tiroidaMulte dintre dereglarile hormonale au drept cauza glanda tiroida. Valorile hormonilor tiroidieni si diagnosticul disfunctiilor tiroidiene se stabilec printr-o analiza a sangelui.

Cei doi hormoni pe care ii produce tiroida se numeste triiodotironina(T3) si tiroxina(T4). Valorile mai mari decat cele normale, in special ale hormonului T3, indica prezenta unei disfunctii numita hipertiroidie. Exista suspiciuni de hipertiroidie atunci cand bolnavul manaca, dar slabeste foarte mult, cand este nervos si agitat, tremura si are palpitatii. Atunci cand cei doi hormoni au valori mici, apare o disfunctie numita hipotiroidie. Spre deosebire de hipertiroidie, hipotiroidia este insotita insa de simptome mai putin evidente.
Pacientul care sufera de aceasta boala este obosit, are edeme in special pe pleoape si pe fata, are tegumentele reci, este somnolent si nu suporta frigul.

Disfunctii:

Cresterea tiroidei si producerea hormonilor T3 si T4 sunt controlate de un alt hormon, numit TSH, care este produs de glanda hipofiza. Si modificarile de valori ale TSH-ului pot da disfunctii tiroidiene, care se numesc subclinice. In unele cazuri, numai valoare TSH-ului este anormala, in vreme ce T3 si T4 sunt in limita normala. In hipertiroidismul subclinic TSH are valori mai mici decat cele normale.

In hipotiroidismul subclinic valoarea TSH-ului este mai mare decat cea normala.

Valorile celor trei hormoni pot fi influentate, de asemenea, de anticonceptionale, de unele medicamente pentru tulburari de ritm cardiac, medicamente pentru boli de ficat, sau in unele boli precum septicemia, insuficienta cardiaca, boli cronice de ficat si boli renale cronice. Nivelul hormonilor se modifica si in timpul sarcinii. in toate cazurile, analizele hormonale vor indica o falsa disfunctie tiroidiana.

Analizele care stabilesc indicii tiroidieni trebuie sa fie efectuate de persoanele cu gusa, a caror afectiune poate fi cauzata de dereglari hormonale. Aproximativ 10% din cauzele de tulburari cardiovasculare se impune stabiliarea valorilor celor trei hormoni. Si in displipidemie(anomalie a nivelului de lipide in sange) cauza ar putea fi de natura hormonala, iar indicii tiroidieni stabilesc acest lucru.
