What's the lowest possible BMI you could have and still survive?Watch
I weigh 77 pound and am 5'3
I am 15
BMI is a rubbish measurement anyway - it drastically inflates the score of big, strong athletes (put in the numbers for an Olympian and chances are they'll come out as overweight because the formula doesn't allow for muscle mass) and can underestimate the score of a short, old person. Body fat % is probably a better measurement. But 13.8 isn't normal by any means, unless you're a very small child. Healthy for a young adult is usually considered 18-25.
Please double-check your calculations because if your BMI is indeed 13.8, you need to call your GP immediately. Your life could be in danger, and only a qualified doctor will be in a position to determine the best course of action.
I'm gonna assume from OPs question and BMI that they probably have an eating disorder. So telling them it's 'not that bad' is really not good advice... someone once told me I could probably 'live to 80' with my BMI after I voiced concerns. I promptly dropped another 15lbs.
See above. Pretty sure OP have an eating disorder.
You must look like a walking Skeleton
go visit your GP ASAP and get yourself checked in somewhere where they can help you get better and provide round the clock support.
seriously, it sounds like you are on deaths door.......
Short term affects of low weight can include low energy, feeling weak, poor focus, susceptibility to injury and illness, issues with periods (if female obviously), emotional issues, poor sleep, coldness.
How low your BMI can be and you still "survive" is a bit of a tough question. It depends on what you mean by survive. You could live with a very low BMI, but have a very uncomfortable life. You could also die of complications. It all depends on the individual.
Long term health implications of low weight at a young age can include weakened heart, bones and muscles, intestinal damage, mental health problems. Some health issues or complications from low weight could also cause death.
That is not a full list and it's not all a guarantee, but low weight is something that you should be careful about. None of us here are going to be able to give you proper advice since we don't know enough about you and most of us aren't medically trained. Your best option is to go have a chat with your GP and work out what's best for you.
Please also mention if you feel like you may be trying to keep your weight low. Anorexia and other eating disorders can sneak up on you and get a lot worse before you notice. It's best to address any little concerns early so you can stop it turning into a big issue.
There is nothing to be ashamed or embarrassed about so just go talk to your GP and sort things out. The most important thing is that you are physically and mentally well and the best way to make sure you are healthy and well is to talk to a doctor. Hope that helps. Good luck
