Underweight is mean you have a body mass index that is below 18.5. Many folks think being fat is a health risk, they might think being too skinny is good. But being overly skinny carries its own health risks,too.

About four years ago, I happened to have poor absorptions of nutrients. At that time, my weight was unintentionally dropping, and I was overly losing weight. I lost almost 20 pounds in just one month. In school, classmates and teachers started to give me dirty looks. Even when I go to the grocery stores with my mom, people ooked at me like I was from a differernt planet. I felt so bad. I did not try to lose any weight, and I was eating as much as I used to, since then I even tried to eat as much as I could everytime till I throw up. My family started to worry about me because I eat so much, but still did not gain any weights. They forced me to stop exercise and rest, at that time, they would just put me to bed after dinners. Finnally they took me to the doctor. The doctor said that I might suffered with an eating disorder. But after he arranged the blood test and all of those long examations for me, he told my family that I was diabetic, and I had to go on drugs to control it. Because diabetes affects the way my body uses the blood surgar, I would lose weight if my body do not get enough of suger to generate, even I might be eating as much as usual.

For most people, losing a few pounds without meaning to could be a good thing to them. But it’s important to know when unexpected weight loss is a serious cause for concern. And sometimes, unexpected weight loss can be a sign of a depressive illness, many cancer cause unintentional weight loss as well.
