Tonsils are two oval-shaped glands located at the back of the throat. They play a key role in fighting bacteria and viruses that enter through the mouth or nose.
When these tissues become infected, they can swell and cause discomfort, leading to a condition known as tonsillitis — one of the most common throat infections affecting both children and adults.
Many people wonder, “How do I know if I have tonsillitis?” The answer lies in recognizing the body’s early warning signs such as sore throat, fever, or difficulty swallowing.
This article by Magrabi Hospitals highlights the key symptoms, how they differ between adults and children, and when medical attention is necessary.
Tonsillitis happens when the tonsils become inflamed due to viral or bacterial infection.
Most cases are caused by common respiratory viruses, but in some cases, bacteria — especially Streptococcus — are responsible for more severe infections.
Inflamed tonsils usually appear red, swollen, and painful, making swallowing difficult.

Tonsillitis symptoms vary depending on the cause and severity, but typically develop from a mild sore throat into more obvious signs.
The first and most common symptom. Pain may spread to the ears or jaw.
Swollen tonsils can make swallowing or speaking painful, especially when eating solid food.
Visible redness or swelling may be noticed when opening the mouth.
These are typical of bacterial tonsillitis, according to the Saudi Ministry of Health. Always seek medical advice before taking antibiotics.
A temperature above 38°C (100.4°F) often indicates bacterial infection.
Tender lumps under the jaw or behind the ears signal an immune response to infection.
Caused by bacteria buildup or mouth breathing due to throat blockage.
If you notice several of these symptoms together, book an appointment with an ENT specialist at Magrabi Hospitals for proper diagnosis and treatment.
Tonsillitis is common in children, especially before school age.
The symptoms are similar to those in adults but may appear more intense. Watch for fever, poor appetite, snoring, or difficulty swallowing or breathing.
If these persist for more than three days, seek medical help promptly to avoid complications.

Although tonsillitis affects adults less frequently, it can be more severe and last longer.
Common symptoms include:
Seek medical attention if symptoms persist beyond three days or if breathing or swallowing becomes difficult. Recurrent infections may indicate chronic tonsillitis requiring further evaluation.
Understanding whether the infection is bacterial or viral is key to receiving the right treatment.
Distinguishing between bacterial tonsillitis symptoms and viral tonsillitis symptoms helps determine the right treatment plan.
Usually caused by common cold or flu viruses.
Typical signs:
Most often caused by Streptococcus bacteria.
Typical signs:
As advised by the Saudi Ministry of Health and the Saudi Food & Drug Authority, antibiotics should only be used after medical confirmation through a throat swab test.
Seek medical care if symptoms persist longer than three days, if swallowing or breathing is difficult, or if fever and swelling are severe or recurring.

Many people confuse throat infections with tonsillitis because of similar symptoms.
A throat infection affects the entire throat and is often mild and viral, while tonsillitis specifically targets the tonsils.
If symptoms persist or recur, visit an ENT specialist at Magrabi ENT Department for a full examination.
How can I tell the difference between a sore throat and tonsillitis?
A sore throat usually affects the throat lining and improves on its own. Tonsillitis involves inflamed, enlarged tonsils often with white patches and fever.
What effect does tonsillitis have on the body?
Mild cases cause throat discomfort, but repeated infections can lead to bad breath, fatigue, sleep problems, and, if untreated, complications like abscesses or ear infections.
What are the symptoms of tonsillitis in adults?
Severe throat pain, difficulty swallowing, swollen red tonsils, fever, bad breath, and swollen neck glands. Pain may radiate to the ears or jaw.
