Anorexia is an eating disorder. If you have anorexia, you're obsessed with becoming thinner even if you're already underweight. This obsession makes you do one of two things:
As a result you lose more weight than is healthy for your age and size. You may lose so much weight you become seriously ill or even die. Despite looking thin and ill, you stay convinced you are too fat.
Anorexia may be caused by social pressures to be thin. The disorder can run in your family.
When you have anorexia, your whole life revolves around how much you eat and how much you weigh. You are so convinced you're fat that you may not eat enough food. Sometimes you may eat a huge amount at once and then make yourself throw up. Even as you get too thin, you want to be even thinner. You may:
Complain about being overweight, even though you’re very thin
Think about food all the time
Measure your food and count calories
Hoard, hide, or throw away your food
Pretend to eat or lie about how much you’ve eaten
Exercise a lot more than usual
Wear bulky clothes or lots of layers
Weigh yourself many times a day
Feel good about yourself based on how thin you think you look
Anorexia isn't just about looking too thin. If you lose too much weight, you can damage your whole body. Anorexia may cause:
If you make yourself throw up a lot, the stomach acid will damage your teeth. If anorexia gets very bad, it can affect the chemical balance in your body which can cause serious heart problems or even death.
Anyone can get anorexia. It is more likely to start in the teen or young adult years. It is much more common in girls and women.
People with anorexia are often able to hide it from their loved ones. This means that family and friends may not know about it until it’s very bad and life-threatening. Learning the symptoms of anorexia can help you recognize it in someone you love.
Doctors will check your height and weight to see if you weigh too little for how tall you are. They’ll also ask you how you feel about your body and your weight.
If anorexia seems likely, doctors will do a physical exam. They'll order blood and urine tests to check for problems caused by anorexia. A test to check for thinning of your bones and a test for abnormal heart rhythms may also be done.
If you've lost a lot of weight or lost weight very quickly, doctors will try to help you regain weight. This may involve:
Sometimes doctors give you medicines to treat anxiety and depression. When your mood is better, you may eat more and gain weight.
