Do Adenoids affect the oxygen in the brain ,how important it si to operate these adenoids?

My daughter is 3 years old and is suffering for the past few months with bad cold and breathing problems specially at night ,if could help me

Yes adenoids and enlarged tonsils can cause some oxygen deprivation especially at night. Yes it is an easy out patient procedure to have done. My 5yr old had it done a year ago. Need a Dr's reference though.

Adenoids are in the upper throat and can affect the breathing if they are enlarged. A couple of my children I was told had enlarged adenoids but did not have any problems with their tonsils like a lot of children do. It did make them snore loud at night when they slept. Usually if a child needs their tonsils out the doctors will remove the adenoids too. I was also told that they shrink as children get older too, or maybe it is that the children grow into them (ha Ha). That last was a joke I really do not know. Hope this helps a little.

The adenoids are fleshy tissue that produce white blood cells and trap bacteria, viruses, and other harmful agents. They do not affect the amount of oxygen to the brain, unless they are over-sized and blocking the intake of air (as they are at the back of the nose), but no more than any other obstruction. Usually removal is unnecessary, as they disappear around the age of 12.

My Experience: I had over sized adenoids until I had them removed at the age of fifteen. As a child my breathing was severely affected, but I was prescribed an inhaler that shrunk them and improved my breathing. Although this did allow me to breathe more or less normally, it was necessary to have them removed, as they had not disappeared when they were supposed to. Since then I have had no trouble breathing.

Talk to a doctor, he or she will probably prescribe something to your daughter to shrink her adenoids.

Adenoids (or pharyngeal tonsils, or nasopharyngeal tonsils) are a mass of lymphoid tissue situated at the very back of the nose, in the roof of the nasopharynx, where the nose blends into the mouth.

Normally, in children, they make a soft mound in the roof and posterior wall of the nasopharynx, just above and behind the uvula.

Excerpt above is from first source below; the excerpt below is from the second source below:

Enlarged tonsils and adenoids are considered a problem when they cause more serious effects. They can cause chronic ear infections and hearing loss due to obstruction of the eustachian tube and fluid accumulation in the middle ear. They can also cause recurring sinus infections and nosebleeds. Some children have obstructive sleep apnea (see Sleep Disorders: Sleep Apnea Syndromes), with snoring and brief periods without breathing; this can cause low oxygen levels in the blood, frequent waking, and daytime sleepiness. Rarely, obstructive sleep apnea caused by enlarged tonsils and adenoids can lead to serious complications, such as high blood pressure in the lungs (pulmonary hypertension) and changes in the heart that result from pulmonary hypertension (cor pulmonale (see Cor Pulmonale: A Disorder Stemming From Pulmonary Hypertension).

NOTE: I suggest that a nasolaryngeal (nose, ear, and throat specialist) be consulted if the obstruction prevents breathing. Oxygen deprevation can result in lethargic disposition (sleepy/dopey) and inadequate circulation to the brain can cause detrimental results. We must breathe freely to function normally.

My brother's stepdaughter had about the same problem and they actually removed her Adnoids. That really did help with her breathing problems. Ask you family doc about it!
