Hi and thanks for the query,
If your daughter is 3 - 12 years old then she may be suffering from enlarged adenoids
Adenoids are situated behind the nose and perform immune functions.
They frequently get enlarged in children and the condition called chronic adenoiditis
is very common.
Only if the problem persists and the nose block becomes very troublesome then the adenoids are surgically removed.
There is no medical treatment for adenoids.
Most children outgrow the problem and become symptom free when they turn 12 - 13 years.
Other conditions affecting your daughter may be common cold
of the nose.
Do not use nasal decongestion drops for more than 5 days in children. It can aggravate her nose block.
Please consult an ENT specialist
to come to a diagnosis.
Regards, Dr Kishori.
