Being underweight could be a sign you're not eating enough or that you may be ill.
If you're underweight, contact your general practitioner for further evaluation.
The medical community recommends that you keep your weight within this range.
People who fall into this category may be at risk of developing obesity. They might also be at risk of developing other health problems, or that their current health problems may worsen. The recommendation is to consult a healthcare provider trained in obesity management.
There are two recommendations for people who fall into the pre-obesity category, which are recommended by European23 and American24 clinical guidelines for obesity management in adults.
The recommendation for people with a BMI between 25.0 and 29.9 who do not have weight-related health problems (i.e. high blood pressure or high cholesterol) is to prevent further weight gain through healthy eating and increased physical activity.23
For people with a BMI between 27 and 29.0, who also have weight-related health problems, the recommendation is to lose weight by combining lifestyle interventions and anti-obesity medications to achieve weight loss and improve health and quality of life.23,24
People with a BMI of 30 or above may have obesity, which is defined as an abnormal or excessive accumulation of fat25 that may harm health. Today, a number of health organisations recognise obesity as a chronic, but manageable disease.23
The World Health Organisation and other health organisations distinguish three classes of obesity:
Obesity Classification BMI
Class I 30.0–34.9
Class II 35.0–39.9
Class III Above 40
The BMI ranges are based on the effect that excessive body fat has on individuals’ health, life expectancy and risk of developing diseases. As BMI increases, so does the risk for some diseases.26
It’s recommended that people with a BMI of 30 or above consult a healthcare provider trained in obesity management for diagnosis, risk assessment and treatment of obesity and weight-related health complications.
The goal of managing and treating obesity is not simply to lose weight, but instead to improve health and lower the risks of other health complications. Even losing as little as five percent of body weight – and maintaining this weight loss – can improve overall wellbeing, while also reducing the risk of weight-related complications.27
There’s a range of scientifically proven treatment options for obesity that may be recommended depending on individual needs, health status and the presence or absence of weight-related complications. Treatment may include a combination of the following options*:

*Acest calculator IMC este pentru adulți cu vârsta de 20 de ani sau mai mare. Dacă aveți vârsta sub 20 de ani, discutați cu medicul dumneavoastră despre valoarea dumneavoastră a IMC.
IMC este o modalitate bună de a verifica riscul bolilor legate de grăsimea corporală. Faptul de a trăi cu supraponderalitate sau obezitate este asociat cu alte boli și cu un risc crescut de mortalitate.1 În general, cu cât mai mare este valoarea IMC, cu atât mai mare este riscul de a dezvolta alte boli cronice legate de obezitate, inclusiv:
Solicitați medicului dumneavoastră mai multe informații despre oricare dintre aceste boli și despre modul în care sunt legate de valoarea dumneavoastră a IMC.
4 recomandări pentru o gestionare mai bună a greutății corporale
IMC este o măsurătoare simplă și obiectivă, însă poate induce în eroare în unele cazuri și pentru unele grupuri de persoane. Cercetările au arătat că IMC este mai puțin precis în predicția riscului de boală la persoane cu vârstă mai înaintată, sportivi, persoanele foarte înalte sau foarte scunde, precum și la persoanele cu constituție corporală mai musculoasă. De exemplu, sportivii de elită sau culturiștii au mai mulți mușchi și cântăresc mai mult, ceea ce face să aibă o valoare IMC mai mare.
Intervalele IMC variază între diferite regiuni și la diferite populații. De exemplu, valorile limită pentru populațiile indiene sau japoneze diferă de cele ale populațiilor occidentale.
De asemenea, IMC nu ia în considerare nici următorii factori:
Este important să vă amintiți că faptul de a trăi cu obezitate nu înseamnă neapărat că sunteți nesănătos/nesănătoasă, la fel cum faptul de a avea greutate „normală” nu înseamnă neapărat că sunteți sănătos/sănătoasă. Valoarea dumneavoastră a IMC nu vă definește, însă cunoașterea și înțelegerea IMC pot reprezenta un instrument util în preluarea inițiativei asupra stării dumneavoastră de sănătate.
Indiferent de valoarea dumneavoastră a IMC, profesioniștii din domeniul sănătății recomandă o dietă sănătoasă și un stil de viață sănătos. Vorbiți cu medicul dumneavoastră despre greutatea dumneavoastră și evaluați acțiunile potențial necesare.
