Mountain Sickness in Kids – What Parents Need to Know
Taking kids up to high elevations can be exciting, but the thin air sometimes bites back. Mountain sickness, also called altitude illness, shows up when the body can't get enough oxygen. It’s not just a grown‑up problem – children feel it too, often faster. Knowing the warning signs and how to react can keep a family trip safe and fun.
Common Signs and Symptoms
Kids often show altitude trouble with a mix of physical and behavioral cues. Look for a headache that won't go away, nausea or vomiting, and a loss of appetite. Irritability, trouble sleeping, and a rapid heartbeat are also red flags. In younger children, you might see clumsiness, stumbling, or a sudden drop in activity level. If a child seems unusually sleepy or confused, that could be a sign of serious trouble and needs immediate attention.
How to Prevent and Treat Altitude Illness
The best defense is a slow rise. If possible, spend a night or two at a moderate altitude before heading higher. Keep kids hydrated – water helps the body adjust, but avoid sugary drinks that can make dehydration worse. Encourage light meals and limit exertion for the first 24‑48 hours. If symptoms appear, the first step is rest and descent. Even a short walk down a few hundred meters can ease headaches and nausea.
Over‑the‑counter meds aren't a cure, but some doctors prescribe acetazolamide (Diamox) for kids who are prone to altitude sickness. The drug helps the body breathe more efficiently by making the blood slightly more acidic, which triggers faster breathing. Dosage is weight‑based, so a pediatrician’s guidance is essential. For moderate to severe cases, a single dose of dexamethasone may be given, but only under medical supervision.
While medication can help, basic care makes a huge difference. Keep the child’s head elevated when they rest, use a cool compress for a pounding headache, and monitor for any worsening signs like swelling in the fingers or persistent vomiting. If any symptom escalates after a few hours of rest, start the descent right away and seek medical help.
Planning ahead saves headaches later. Pack a small altitude kit with a water bottle, electrolyte tablets, a basic thermometer, and any prescription meds your pediatrician recommends. Have an emergency plan that includes the nearest medical facility and a way to call for help, even if you’re off the grid.
Mountain adventures can be memorable for the whole family when you’re prepared. By watching for early signs, moving up slowly, staying hydrated, and knowing when to use medication, you reduce the risk of mountain sickness and keep the focus on fun rather than illness.
