Weight Monitoring (Parenting Role)

Weight monitoring involves regularly recording a child’s weight over weeks and months and comparing it to previous readings. In the case of an eating disorder, especially anorexia, weight is a medical indicator. It shows the treatment team whether the body is getting enough energy, whether circulation and growth remain stable, and whether therapy is working.

This value rarely stands alone. Specialists also look at heart rate, blood pressure, blood test results, and how a child eats and feels. A single number taken in the morning tells us very little. Only the trend over several appointments provides a complete picture.

During treatment, the team determines how often the child is weighed—usually once or twice a week at set times. The weight is recorded there. A one-kilo fluctuation could be due to fluid retention, could be actual growth, or could be a warning sign. Making this distinction requires experience.

Many clinics weigh children “blind”—the child stands with their back to the display and does not see the number immediately. This way, the scale remains a tool for treatment. The child does not have to face the number every day. In family-based therapy, parents take on a great deal of responsibility for mealtimes. Weighing and its interpretation are coordinated with the team throughout the process.

An eating disorder revolves heavily around numbers and control. Weighing oneself daily or multiple times a day at home feeds precisely this fixation. Every slight increase in weight triggers anxiety, often followed by eating less, exercising more, or secretly inducing vomiting.

For parents, this creates a second problem. The scale turns them into enforcers. Every time the child steps on the scale, it can turn into a power struggle, with the child trying to cheat by drinking lots of water beforehand or hiding weights in their clothes. Trust suffers, and focus narrows to a single number, while mood, sleep, and withdrawal fall by the wayside. Anyone familiar with the daily tension at the dinner table can find more on this under “Observing Controlled Eating.”

The first step is to have a clear conversation with the treating practice or clinic. Some useful questions to ask are:

• Who weighs the baby, how often, and at what time of day?
• Should we weigh the baby at home at all, and if so, how?
• Where should we report any abnormalities?

Often, the team advises removing the scale from the bathroom or locking it away. This way, the responsibility for the weight lies with the professionals, and parents can focus on mealtimes and their relationship with their child. Observe your child’s behavior: Does my child eat with us? Do they go to the bathroom immediately after eating? What is their mood like? Do they withdraw? Such observations are more valuable to the team than a home scale. Stick to the agreed-upon plan, even if there are arguments. The rules come from the team, which relieves you of the role of adversary.

Some symptoms require prompt medical evaluation: rapid weight loss, a very slow heart rate, dizziness or fainting, persistent refusal to eat, vomiting, or severe withdrawal. The first points of contact are pediatricians, specialized eating disorder clinics, and counseling centers. In cases of acute physical danger, the child should be admitted to a hospital.

A diagnosis—and the question of how often and by whom the child should be weighed—can only be determined by a child and adolescent psychiatrist (KJP) or a medical or psychotherapeutic specialist. Rückenwind and Janike are here to support you as parents through this time, but they do not provide diagnoses and are not a substitute for medical treatment.
