Step 1
Observe the person and her eating habits over time. Look for when, what and how she eats. Listen for the way she talks about food, weight and clothing sizes.
-
Step 2
Look for other signs of illness, including low-grade fever (characterized by warm hands or a warm face), exaggerated mood swings and frequent trips to the bathroom throughout the day. If you detect any of these symptoms, the problem is probably not anorexia.
-
Step 3
Watch the person to see if his weight loss appears to be increasing, decreasing or staying the same.
-
Step 4
Talk to your loved one directly. Express your concern about her unexplained weight loss and the possibility that she might have anorexia. A negative or evasive answer may be another indicator of anorexia.
-
Step 5
Ask someone close to the person to use his influence with her to halt her unhealthy weight loss. For instance, you might want to speak to her parents about your concerns, particularly if she is a minor. If she is over 18, mention the problem to a roommate, boyfriend or college counselor.
-
Step 6
Work with family and friends to be sure that the person with unexplained weight loss sees a doctor. No matter what the cause, excessive thinness is a dangerous condition that needs to be diagnosed and treated quickly.
