Children with Pectus Excavatum Become Quiet, Avoid Undressing? 4 Psychological Signs Parents Should Take Seriously

Introduction

Many parents, when focusing on Pectus Excavatum correction, pay attention only to how deep the depression is, whether the vacuum bell has been worn enough, and whether follow‑up data look good – but they overlook the child’s own changes.

Some parents realise in hindsight: their child used to be lively and talkative, but at some point they started staying home, avoiding mirrors, and refusing group activities. This silence is often more concerning than the chest depression itself.

1. Why Does Pectus Excavatum Make Children Withdrawn?

The psychological pressure on children with pectus excavatum comes mainly from three sources:

1. Shame from Appearance Differences

The chest depression of pectus excavatum is visually noticeable, especially in situations where they need to take off their shirt (e.g., changing for PE class, swimming, medical examinations). Children easily realise that they are “different from others.” This appearance difference is particularly sensitive during puberty and can create intense shame and self‑denial.

2. Social Withdrawal Due to Peer Reactions

School‑aged children are very sensitive to “difference.” A single comment like “Why is your chest caved in?” or a strange look from classmates after swimming class can make a child choose to avoid social situations – skipping swimming class, refusing sports activities, and being afraid to make new friends.

3. Pressure Transmitted from Parental Anxiety

Parents anxious about correction results constantly remind the child: “Have you worn it enough today?” “Why didn’t you wear it again?” – intended as caring, but the child may feel “I’m not good enough” or “I’m worrying my parents.” This continuous transmission of anxiety can easily make the child become quiet and withdrawn.

A survey study published in the Chinese Journal of Pediatric Surgery showed that a high proportion of children with pectus excavatum have psychological problems of varying degrees, with social withdrawal and low self‑esteem in adolescents being particularly prominent. However, most parents do not proactively mention their child’s mental state during medical visits [1].
