Adenoid Symptoms: The Signs That Tell You It’s Time to See a Doctor

Last Update: 11/11/2025

Introduction

Adenoid enlargement is a common condition that often goes unnoticed at first but gradually causes breathing difficulties, nasal blockage, and snoring during sleep.
The symptoms of adenoid hypertrophy vary between adults and children, and may even be mistaken for allergies or sinus infections.
Recognizing these warning signs early can help you seek timely medical advice and avoid complications.

 

 

To understand what adenoids are and why they become enlarged, you can read What Are Adenoids?

 

 

 

What Are Adenoids and Why Do Symptoms Appear?

The adenoids are a soft lymphatic tissue located behind the nose and above the throat. They play an important role in the immune system by filtering bacteria and viruses entering through the nose.
When adenoids become enlarged due to recurrent infections or allergies, they block the nasal airways and lead to nasal congestion, snoring, and mouth breathing, all of which are key symptoms of adenoid hypertrophy.
If left untreated, the condition may worsen and start affecting sleep quality, breathing, and even hearing—especially in children.

 

 

Adenoid Symptoms in Adults

In adults, adenoid symptoms tend to develop gradually and are often mistaken for chronic allergies or sinusitis.
However, persistent symptoms can indicate an enlarged adenoid tissue obstructing airflow.
The most common signs of adenoid hypertrophy in adults include:

• Chronic nasal obstruction, particularly noticeable at night.
• Difficulty breathing through the nose and habitual mouth breathing.
• Loud snoring or disturbed sleep.
• Dry mouth in the morning caused by mouth breathing during sleep.
• Reduced or lost sense of smell.
• Frequent headaches or facial pressure due to retained secretions.
• Fatigue or poor concentration resulting from poor sleep quality.
• Change in voice tone (nasal or muffled speech) in advanced cases.

These symptoms are among the most frequent signs of adenoid hypertrophy seen in adults.

According to the Saudi Ministry of Health, adults experiencing persistent nasal obstruction, snoring, or other unexplained respiratory symptoms should consult an ENT specialist to ensure an accurate diagnosis.

 

Adenoid Symptoms in Children

The symptoms of adenoid enlargement in children are usually more noticeable, as narrow airways and recurrent infections can easily affect breathing and hearing.
Here are the most common signs parents should watch for:

1. Constant mouth breathing, especially during sleep.
2. Nighttime snoring or sleeping with an open mouth.
3. Changes in voice tone or delayed speech development.
4. Hearing difficulties or frequent ear infections due to middle ear blockage.
5. Restless or interrupted sleep.
6. Daytime fatigue or lack of concentration caused by poor sleep quality.
    

These warning signs often resemble other upper respiratory conditions, so it’s essential to consult a pediatric ENT specialist for proper evaluation.

(The Saudi Food and Drug Authority SFDA advises parents not to administer antibiotics or any medication to children without a doctor’s prescription, as misuse can lead to antibiotic resistance and reduced treatment effectiveness.)

 

 

Complications of Adenoid Hypertrophy

What are the complications of adenoid hypertrophy if left untreated or undiagnosed?
In many cases, the condition can lead to several health problems affecting breathing, hearing, and sleep quality.
The most common complications include:

• Chronic ear infections due to blockage of the Eustachian tube
• Temporary or permanent hearing loss caused by persistent middle ear fluid.
• Sleep disturbances, such as snoring or sleep apnea.
• Chronic mouth breathing, leading to dry mouth and sore throat.
• Changes in facial structure in children (“adenoid face”) due to prolonged mouth breathing.
• Fatigue and poor concentration from low oxygen levels during sleep.

 

 

ENT specialists at Magrabi Hospitals note that many patients arrive in advanced stages of adenoid hypertrophy—often because early symptoms were ignored or confused with sinus or tonsil problems.
Therefore, doctors recommend visiting the ENT Department at Magrabi Hospitals promptly whenever persistent or unclear respiratory symptoms appear.
To clarify the differences, the next section explains how to distinguish adenoid symptoms from sinus or tonsil symptoms.

 

 

Difference Between Adenoid, Sinus, and Tonsil Symptoms

The symptoms of adenoid hypertrophy often overlap with sinusitis and tonsillitis, making self-diagnosis difficult.
However, doctors can identify subtle distinctions:

• Adenoid hypertrophy mainly causes nasal obstruction and mouth breathing, without significant throat pain.
• Sinusitis usually causes facial pain or pressure and thick nasal discharge that may be yellow or green.
• Tonsillitis presents with throat pain, difficulty swallowing, and high fever, and the tonsils appear visibly swollen on examination.

If you’re unsure about your symptoms, always consult an ENT specialist for an accurate diagnosis.

When to See a Doctor

Monitoring symptoms is key to preventing serious complications from adenoid hypertrophy.
You should see a doctor if you experience:

• Persistent nasal blockage unresponsive to home remedies.
• Frequent snoring or pauses in breathing during sleep.
• Difficulty breathing through the nose.
• Recurrent ear infections or hearing loss, especially in children.
• Changes in voice tone or delayed speech in children.

All of these could indicate enlarged adenoids that require proper medical evaluation.
Magrabi Hospitals continues to invest in advanced ENT diagnostic technologies and highly qualified specialists to ensure accurate diagnosis, effective treatment, and improved patient comfort.

 

FAQ

How do I know if I need adenoid surgery?

Surgery may be required if symptoms persist despite medication—such as chronic nasal obstruction, recurrent snoring, or hearing loss due to blocked Eustachian tubes.
Your ENT doctor will assess the degree of enlargement using nasal endoscopy or imaging and determine if surgical removal is necessary to prevent further adenoid complications.

What’s the difference between adenoids and sinuses?

While both affect breathing, they differ in structure and function.
The adenoids are lymphatic tissue behind the nose that can enlarge and block airflow, while the sinuses are air-filled cavities in the facial bones that can become inflamed, causing facial pain and nasal discharge.

How do I know if my child has adenoids?

Parents should watch for mouth breathing, snoring, hearing issues, or speech delays.
These are common adenoid symptoms in children.
If these signs persist, consult a pediatric ENT specialist for evaluation.
For full guidance, read Adenoids in Children: Causes, Symptoms, and Treatment.

How do I know if I have adenoids in my nose?

Adults with enlarged adenoids often experience chronic nasal obstruction, snoring, and loss of smell.
As these symptoms are easily confused with allergies, it’s best to have an ENT doctor perform a nasal endoscopy for confirmation.

Conclusion

Adenoid hypertrophy should not be ignored, as it can significantly affect breathing, sleep, and hearing.
Early diagnosis and proper treatment help prevent complications and restore normal respiratory function.
