Wellness in Teens

13 TO 17 YEARS

The teenage years bring new experiences, deeper self‑awareness, and greater independence. With support and encouragement, teens with achondroplasia can confidently face what’s ahead

Potential Medical Complications in Teens With Achondroplasia

Achondroplasia may be associated with specific medical complications, though most teens will not experience everything listed here. Proactive care and support can make a meaningful difference. Learn more below about how to help support your teen’s health.

TRACKING GROWTH AND DEVELOPMENT IN TEENS with achondroplasia

Every teen with achondroplasia grows and develops in their own way and at their own pace. Using growth charts made specifically for children and teens with achondroplasia helps your teen’s doctor track their height, weight, and head size more accurately. These charts reflect the unique growth patterns of achondroplasia and allow for better monitoring of over time. Standard weight and body mass index (BMI) charts, by contrast, often overestimate how much extra weight a teen is carrying, making them less reliable for this group.

As your teen grows, differences in body proportions from average-height peers, like shorter arms and legs compared with the torso, may become more noticeable. This is a typical part of how a teenage body grows with achondroplasia.

Puberty in teens with achondroplasia

During puberty, some physical changes may appear different in teens with achondroplasia compared with their average-height peers.
  • Teens with achondroplasia don’t experience a typical growth spurt during puberty, so they gain less height overall compared with their peers. As average-height teens grow rapidly during this time, the height difference may become more noticeable
  • Most growth occurs in the torso, increasing sitting height more than standing height
  • Body proportions may change, making the difference in limb and torso length more noticeable

Every teen experiences puberty in their own way. Talking openly about these changes and reminding them of what’s normal for their body can be helpful. Health care providers can offer support if questions come up.

Some teens with achondroplasia may also experience body image concerns during this stage of life. Encouraging open, supportive conversations and creating a positive environment can help them navigate these feelings (see Building a positive environment for your child with achondroplasia).

Managing a healthy weight during the teenage years

Teens with achondroplasia may be more likely than their average-height peers to gain extra weight starting at a young age. This can happen for several reasons, including differences in the way their body uses energy, lower activity levels, and social or emotional stress.

Maintaining a healthy weight can support overall well-being and help reduce the risk of sleep apnea, joint and back pain, and heart problems later in life. Building healthy habits like encouraging active play, offering balanced meals, and creating a positive, supportive environment can help teens feel their best. Weight can be a sensitive topic, especially for teens who may already feel different or face challenges related to body image. It’s important to approach any conversations on this topic with care, focusing on health rather than appearance.

Standard weight and BMI charts are not accurate for teens with achondroplasia and often overestimate excess weight. That’s why it’s recommended to use achondroplasia-specific growth charts for more reliable tracking over time.

Experts recommend:

  • Scheduling yearly check-ups with a pediatrician
  • Building a balanced diet using foods from all 5 food groups
    • Make half the plate vegetables or whole fruits
    • Choose mostly whole grains
    • Include a variety of lean proteins
    • Incorporate low-fat dairy products
    • Limit foods and drinks high in added sugar and saturated fat
  • Encouraging daily physical activity that your teen enjoys
  • Offering emotional support and reassurance as needed

If you are concerned about your teen’s weight, speak with a registered dietitian, ideally someone with pediatric experience. Every teen is different, and their care team can help you find what works best for your teen’s health and confidence.

Anesthesia safety in teens with achondroplasia

Some teens with achondroplasia will need anesthesia for certain tests or surgeries that require them to remain still, like certain scans or ear tube insertion procedures. Many teens with achondroplasia undergo surgery without any problems, but they may face certain risks with anesthesia, such as:

  • Uncontrolled neck movement leading to squeezing of the spinal cord and breathing problems
  • Receiving the wrong medication dosage
  • Difficulties with inserting an intravenous line due to limited elbow extension
  • Difficulties with placing a breathing tube if it’s needed

To help reduce risks, it’s important that your teen receives care from an anesthesiologist experienced in treating patients with achondroplasia.

For certain surgeries, especially those involving the spine, doctors may also recommend neuromonitoring. This is a technique that helps track the health of the nerves in real time, adding an extra layer of safety.

If your teen has obstructive sleep apnea (OSA), they may need additional monitoring or other special precautions before, during, and after anesthesia. OSA can cause pauses in breathing during sleep, and anesthesia can make this more likely by relaxing the muscles that keep the airway open. For this reason, medical guidelines recommend that anesthesia be provided by an anesthesiologist with experience caring for individuals with OSA.

You can also talk to your teen’s care team about the Skeletal Dysplasia Management Consortium’s Guidelines, which outline best practices to support safe anesthesia care.

Dental and Orthodontic Considerations for teens with achondroplasia

Teenagers with achondroplasia may have differences in how their teeth are spaced and how their upper and lower jaws line up. Although these differences can occur in all teens, they are particularly common in teens with achondroplasia and can sometimes impact speech. Like other teens this age, management may include braces to guide tooth alignment or palate expansion to widen the jaw and make more room for teeth.

Some teens with achondroplasia may also need extra care during dental visits. Not every dental or orthodontic procedure requires anesthesia, but some do. Because teens with achondroplasia have unique safety considerations, it is important to review these with the care team.

Whenever possible, it is recommended to seek dental care from a
clinic with experience treating patients with achondroplasia.

Optional Procedures, Treatments, and Research Studies for TEENS With Achondroplasia

Some families may consider a treatment or procedure at different points in their teen’s journey. Choosing whether to start or continue an optional treatment is a personal decision.* It may help to talk with achondroplasia experts, involve your teen when appropriate, connect with other families, and explore resources like advocacy group websites.

For information about approved medications for achondroplasia or procedures like limb-lengthening surgery, talk to your teen’s healthcare provider.

For information about clinical trials studying potential medications for achondroplasia, visit ClinicalTrials.gov.
