Indeks tjelesne mase (eng. Body Mass Index - BMI) je popularni alat koji koriste lijeènici za brzu procjenu optimalnosti tjelesne te¾ine pojedinca. Vrlo je jednostavan i temelji se na odnosu tjelesne te¾ine i visine osobe. ©to je veæi indeks, to je veæi i rizik od oboljenja od raznih srèanih bolesti, dijabetesa i problema sa visokim tlakom. Naravno, ovo je samo jedna od metoda za procjenu je li Va¹a te¾ina u granicama po¾eljne i ne mo¾e se primijeniti jednoznaèno za cijelu populaciju. Za potpunu i sigurnu procjenu, obratite se Va¹em lijeèniku koji za razliku od ovog kalkulatora u obzir uzima i sve specifiène faktore, te mo¾e poduzeti dodatne testove, koji su relevantni za svaki individualni sluèaj. |
