TEMPO.CO, Jakarta – There are eight types vitamin B, one of which is B12. Vitamin B12 helps the body produce red blood cells, process vitamin B9 (folic acid), convert food into energy sources, and keep the nervous system and immune system healthy.
Vitamin B12 juga merupakan salah satu penyusun tubuh karena mendukung sistem saraf dan membantu pembentukan DNA. Kekurangan vitamin B12 yang berkepanjangan dapat memicu masalah kesehatan seperti disfungsi sensorik. Hilangnya penciuman mungkin merupakan tanda kadar vitamin B12 rendah, menurut sebuah penelitian.
Melansir Express, studi yang diterbitkan dalam International Forum of Allergy and Rhinology berusaha menyelidiki hubungan antara disfungsi penciuman dan kadar B12 yang rendah. Olfactory dysfunction (OD) atau disfungsi penciuman didefinisikan sebagai berkurangnya atau terdistorsinya kemampuan mencium selama mengendus (penciuman ortonasal) atau makan (penciuman retronasal).
Penelitian melibatkan 39 pasien dengan kadar vitamin B12 rendah dan 34 kontrol. Semua peserta menjalani pemeriksaan otorhinolaryngological (praktik medis yang melibatkan telinga, hidung, dan tenggorokan) dan tes laboratorium. Mereka menggunakan tes Sniffin' Stick untuk menganalisis fungsi penciuman.
The two groups in the study were compared for odor test results. The correlation of olfactory test results with demographic and laboratory data was investigated in the vitamin B12 deficient group. In the vitamin B12-deficient group, loss of smell was evident in 56.4 percent of patients but none of the subjects in the control group had olfactory dysfunction. In this study, researchers demonstrated for the first time that olfactory dysfunction can occur in patients with vitamin B12 deficiency.
“Apart from the negative correlation of age with odor identification scores, no other parameters studied showed a correlation with olfactory dysfunction,” the researchers wrote.
Meanwhile, other symptoms of B12 deficiency include extreme fatigue, lack of energy, shortness of breath, weakness, headache, pale skin, heart rate can be felt (palpitations), hearing sounds that come from within the body instead of an external source (tinnitus), and loss of appetite. appetite and weight loss.
