Ask Doctor Cory.

Dear Dr. Cory:

Why does your nose run when you go outside in the cold and then come back in?
Amanda Morphew
Midland, Texas

Dear Amanda:

When air that has been warmed and moistened in your lungs hits cold, dry, outside air, moisture condenses (or separates from the warm air) in your nose. Then, thanks to gravity, the drips begin.

Dear Dr. Cory:

A few kids in my church have Down's syndrome. How do you get this disease?
Sarah Boehm
Rochester, New York

Dear Sarah:

Down's syndrome is not a disease like the flu, so you can't catch it like other diseases. It is a genetic condition, which means that people who have it were born with it.

Down's syndrome is caused by the presence of an extra chromosome in the genetic material a person receives from their parents. Usually, a person gets twenty-three chromosomes from each parent, for a total of forty-six. Down's syndrome children have forty-seven chromosomes.

Most Down's syndrome children develop physically and mentally more slowly than other children. They often have some amount of physical disability.

Dear Dr. Cory:

If my friend throws up a lot at school and at home when she is not sick, what does that mean? Is it bad for her health? And could you please tell me what I can do to help her?
Leighann Collins
St. Petersburg, Florida

Dear Leighann:

It's hard to answer your question without knowing more about your friend. Is she losing weight? How much, how often, and what times of day does she vomit? She may have a nervous stomach, a cough, or an overactive gag reflex. Or more seriously, the vomiting could be caused by pressure inside the brain or an eating disorder.

Some people who see themselves as heavier than they are have eating disorders. They are very fearful of gaining weight, so they do things to avoid it like extreme dieting or making themselves vomit.

Eating disorders can cause serious health problems, even death, and require a doctor's care.

Suggest to your friend that she should see a doctor about her vomiting. If she is unwilling, then talk to your parents about giving this information to your friend's parents. They may be unaware of the problem.

See you next issue! Your friend,

Cory SerVaas, M.D.
