Kev ntsuam xyuas cov pob txha ntxhia lub cev

Kev ntsuam xyuas pob txha ntawm cov pob txha (BMD) ntsuas seb cov calcium thiab lwm yam minerals muaj ntau npaum li cas nyob rau thaj tsam ntawm koj cov pob txha.

Qhov ntsuam xyuas no yuav pab koj tus kws kho mob kuaj xyuas txha txhav thiab kwv yees koj qhov kev pheej hmoo yuav pob txha lov.

Kev kuaj cov pob txha ceev tuaj yeem ua tiav ntau txoj hauv kev.

Txoj kev siv sib raug zoo tshaj plaws thiab siv qhov tseeb yog siv hluav taws xob xaim hluav taws xob xaim hluav taws xob 2-lub zog hluav taws xob xoo hluav taws xob (scanXA). DEXA siv duab xoo hluav taws xob tsawg. (Koj tau txais hluav taws xob ntau los ntawm xoo hluav taws xob hauv siab.)

Muaj ob hom DEXA scans:

• Nruab nrab DEXA - Koj dag ntawm lub rooj muag muag. Lub scanner hla koj lub nraub qaum thiab lub ntsag. Feem ntau, koj tsis tas yuav hle khaub ncaws. Kev kuaj kab mob no yog qhov kev sim zoo tshaj plaws los twv seb koj qhov kev pheej hmoo yuav puas, tshwj xeeb yog ntawm lub ntsag.
• Peripheral DEXA (p-DEXA) - Cov tshuab me me no ntsuas lub cev pob txha ntawm koj lub dab teg, ntiv tes, ceg, lossis pob taws. Cov tshuab no nyob hauv chaw kho mob, tsev muag tshuaj, tsev khw, thiab hauv cov rooj noj mov huv.

Yog tias koj cev xeeb tub lossis xeeb tub, qhia koj tus kws khomob uantej qhov kev ntsuas no tiav.

TSIS TXHOB noj tshuaj calcium rau 24 teev ua ntej ntsuas.

Lawv yuav qhia koj kom tshem tag nrho cov khoom hlau tawm hauv koj lub cev, xws li cov hniav nyiaj hniav kub thiab cov buckles.

Lub scan tsis mob. Koj yuav tsum tau nyob twj ywm thaum lub sijhawm kuaj.

Cov pob txha ntxhia ua kom nruj (BMD) raug siv los:

• Kev kuaj mob pob txha poob thiab txha
• Saib seb cov tshuaj kho pob txha ua haujlwm zoo npaum li cas
• Kev kwv yees koj txoj kev pheej hmoo rau cov pob txha ntawm lub cev puas yav tom ntej

Kev ntsuam xyuas pob txha ua kom zoo yog pom zoo rau txhua tus pojniam hnub nyoog 65 thiab laus dua.

Tsis muaj kev pom zoo tag nrho ntawm seb cov txiv neej puas yuav tsum tau yauv xeem yam no. Qee pawg neeg pom zoo kuaj cov txiv neej thaum muaj hnub nyoog 70 xyoo, hos lwm qhov hais tias cov pov thawj tsis tau meej txaus los hais tias txiv neej lub hnub nyoog no puas tau txais txiaj ntsig los ntawm kev soj ntsuam.

Cov poj niam yau, thiab cov txiv neej tsis hais hnub nyoog li cas, tej zaum tseem yuav tau kuaj tus pob txha ceev yog tias lawv muaj kev phom sij ua pob txha pob txha. Cov kev pheej hmoo txaus ntshai no suav nrog:

• Lov pob txha tom qab hnub nyoog 50
• Cov tsev neeg muaj keeb kwm khov kho txha osteoporosis
• Keeb kwm ntawm kev kho tus mob prostate lossis mob cancer mis
• Keeb kwm ntawm kev mob xws li mob caj dab, mob ntshav qab zib, mob qog, lossis mob tsis nco qab
• Lub cev ntas thaum ntxov (los ntawm cov kev ua kom ntuj los yog hysterectomy)
• Kev siv tshuaj ntev ntev xws li corticosteroids, thyroid hormone, los yog aromatase inhibitors
• Tsawg lub cev nyhav (tsawg dua 127 phaus) lossis lub cev nyhav qis tshaj (tsawg dua 21)
• Tseem ceeb poob ntawm qhov siab
• Haus ntev lossis haus cawv ntau dhau

Cov txiaj ntsig ntawm koj qhov kev ntsuas feem ntau yog qhia raws li T-qhab-nees thiab Z-qhab-nees:

• T-qhab nia piv koj pob txha ceev nrog tus poj niam hluas noj qab nyob zoo.
• Z-qhab-nees piv koj pob txha ceev nrog lwm tus neeg ntawm koj lub hnub nyoog, poj niam txiv neej, thiab haiv neeg.

Nrog rau tus qhab nia twg, tus lej tsis zoo txhais tau tias koj muaj pob txha nyias dua li qhov nruab nrab. Tus tsis zoo ntau tus lej, ntau dua qhov koj yuav muaj pob txha lov.

T-qhab nia nyob hauv qhov qub yog tias nws yog -1.0 lossis siab dua.

Kev ntsuam xyuas cov pob txha ntawm cov pob zeb ua kom sib txawv tsis pom kev puas. Nrog rau lwm cov kev pheej hmoo uas koj yuav muaj, nws yuav pab kwv yees koj qhov kev pheej hmoo yuav muaj pob txha lov yav tom ntej. Koj tus muab kev pab yuav pab koj kom nkag siab cov txiaj ntsig tshwm sim.

Yog tias koj tus qhab nia T:

• Ntawm -1 thiab -2.5, tej zaum koj yuav muaj pob txha ntxov (txha pob txha)
• Hauv qab -2.5, koj yuav muaj kab mob txha caj qaum

Cov lus pom zoo rau kev kho mob nyob ntawm koj qhov pheej hmoo pheej hmoo tag nrho. Qhov kev pheej hmoo no tuaj yeem raug suav nrog siv cov qhab nia FRAX. Koj tus kws khomob tuaj yeem qhia koj ntau ntxiv txog qhov no. Koj tseem tuaj yeem nrhiav cov ntaub ntawv ntsig txog FRAX online.

Cov pob txha ntxhia siv hluav taws xob tsawg me ntsis rau hluav taws xob. Cov kws tshaj lij feem ntau xav tias qhov kev pheej hmoo yog muaj tsawg heev thaum piv nrog cov txiaj ntsig ntawm kev tshawb pom txha os ua ntej koj tsoo pob txha.
