Losing weight for no reason?

before you read this I would just like to say that I am not anorexic. I am 5'6 and wrighg like 90 I have always been like that but latley I have been loosing so much weight like I am in the low 80's and I don;t know why. I have been very week and so...

tried. like couple days ago my brother had to carry me to the car because I was to tired. I have a physical like in a couple of days and I don't want them to think I am doing this on perpouse. How do I wake myself up and get dtornger and gain weight? I go running every day, then dance.
Thank you

Go to the doctor, I am serious you can hutr yourself

id depends on what weight you mean...lkilos or pounds
if you mean pounds you seriously need to get help right now
the weakness you feel is due to your body not being abple to function properly with so little weight
you can actually die from this
...its isnt something you can take care of yourself
right now you are extreemely underweight
you must go to a doctor or a hospital
because seriously...your life is at risk right now

okay you definitely need to go to a doctor and get blood work done to check your liver and heart. I know you say you are not anorexic but I have a friend who was and since you are underweight just as she was here is what I when t through with her. first, when you are underweight your liver will begin to shut down and your heart will have to work twice as hard and eventually give out. you need to buy some meal replacement shakes and bars and consume as much as you can. they contain vitamins and the nutrients you need to put on weight. if you are under 85 lbs you could possibly be admitted into the psych ward at your local hospital because your body is in serious trouble and they have nutritionists that work with anorexics that can help you. please see a doctor. also, check and see if you have red dots appearing on your body (legs especially) as this is a sign your liver is failing.

        Simply a Rose to brighten your day,
        And maybe lessen the cares in your way;
        And also, too, to help you to know,
        That in knowing you, many others grow!

You should weigh between 117 and 143 pounds. You DO have an eating disorder, probably anorexia, whether you want to admit it or not. If you don't seek help, you are in danger of doing serious harm to your body which can even include death.

I had to use the Adult weight chart because the Teen chart doesn't address your height.

  
Normal Adult Height-Weight Range Table

You have a BMI of 13.72.

BMI is equal to or less than 18.5 (Underweight)

A lean BMI can indicate that your weight maybe too low. You should consult your physician to determine if you should gain weight, as low body mass can decrease your body's immune system, which could lead to ilness such as disappearance of periods (women), bone loss, malnutrition and other conditions. The lower your BMI the greater these risks become.

well dont boxers and people like that take weight gain bars - they also contain lots of protein (so errmmm protien bars I suppose) xx

you may have a muscle disorder- muscle weighs more than fat and stuff. see a docter. it may be the reason youre feeling so weak, so exercise and eat healty.
