Q. Is a BMI of 16.4 dangerously low?
Doctor Answer is medically reviewed by SecondMedic medical review team.
The body mass index (BMI) is a measure of body fat based on height and weight that applies to both adult men and women. A BMI of 16.4 would be considered significantly below average, and it could be dangerous to one's health if sustained over a long-term period.
Typically, an ideal BMI is between 18.5 - 24.9, so anything below 18.5 would generally be classified as underweight or malnourished. The World Health Organization defines individuals with a BMI lower than 16 as being severely thin or underweight, placing them at risk for various health complications including:
• Poor immunity- Low levels of essential nutrients can prevent the immune system from functioning at its best leading to increased susceptibility towards infections;
• Reduced muscle strength - Malnourishment can lead to reduced muscle strength which may limit physical activity thus hampering daily activities;
• Anemia – Iron deficiencies due to inadequate nourishment can cause anemia as well as low energy levels;
• Osteoporosis/Bone Fractures – Nutrient deficiencies decrease bone mineral density resulting in weak bones that are more prone to fractures;
• Hormonal imbalances- Deficiencies in certain vitamins and minerals can disrupt hormone production and metabolism leading to issues such as infertility or amenorrhea (absence of menstrual periods);
In addition, having such a low BMI might also indicate other underlying medical conditions like eating disorders, kidney disease, liver disease etc., that should not be ignored or taken lightly but rather investigated further by consulting healthcare professionals when the symptoms persist for too long despite dietary intervention . It is important therefore for people with BMIs less than 16 to seek immediate medical assistance along with taking steps towards improving their diet in order ensure proper nutrition intake.
