Question:

My 10-year-old daughter's fingernails don't seem to be growing. When I compare them to a month ago, there's almost no change. However, her toenails are growing normally. Could there be a problem?

Answer:

It must be worrying to see your daughter's fingernails growing so slowly.

【Situation Summary】

A 10-year-old girl's fingernails have shown almost no growth for a month, while her toenails are growing normally.

【Point of Reassurance】

Fingernail growth speed varies greatly among individuals. Since fingernails typically grow faster than toenails, this reversal warrants a check-up. The cause is more likely to be a local issue (nail-biting, habitual touching, trauma, infection) rather than a systemic health problem. Nutritional or thyroid issues can also be considered in a stepwise evaluation.

【What to Check at Home Now】

• Observe if she has habits like biting, picking, or sucking her fingernails.

• Check for any swelling, redness, pain, or discoloration around the nails.

• Examine the nail surface for unevenness, horizontal or vertical ridges, or splitting.

• Ask about any recent finger trauma (e.g., getting slammed in a door, being hit).

• Note any accompanying symptoms like general fatigue, weight changes, hair loss, or increased sensitivity to cold.

【Questions to Discuss with a Medical Professional】

"What tests are necessary to determine the cause of the delayed nail growth?"

"Would a nutritional assessment (for iron, zinc, protein) or a thyroid evaluation be helpful?"

"At what point would a consultation with a dermatologist be necessary?"

【Referrals and Consultations】

Your current pediatrician may decide to refer you to a dermatologist (specializing in nail disorders) or an endocrinologist (for thyroid or nutritional issues) as needed.

【Warning Signs】

If you notice any of the following, seek a same-day evaluation:

• Severe swelling, pus, or pain around the fingernail.

• Systemic symptoms like fatigue, weight loss, or a persistent fever.

• The entire nail is lifting or falling off.

• Accompanied by symptoms suggestive of thyroid issues, such as hair loss, dry skin, or sensitivity to cold.

For now, please check the observation points listed above and discuss them with your pediatrician during your next regular visit.
