Tonsillitis: Understanding the Causes, Symptoms, and Treatments

There are two lumps of tissue at the back of your throat which are called tonsils. Tonsillitis is a condition when these get infected and inflamed. Your tonsils are part of your immune system and help your body fight germs that enter your mouth through breathing, eating, or drinking. However, different viruses or bacteria can occasionally cause your tonsils to become infected and inflamed thus leading to swell and hurt.

Tonsillitis can happen to anyone, regardless of age, but it is more common in children who have not developed enough immunity to fight germs. Symptoms of tonsillitis include a painful throat, difficulty swallowing, fever, headache, and swollen glands in the neck.


Types of Tonsillitis

Tonsillitis can be either acute or chronic, depending on how long and how often you have symptoms.

Acute tonsillitis is when you get a sudden onset of tonsillitis that makes your throat sore, your tonsils swollen, and your temperature high. You usually need to take antibiotics and rest for a few days or a week until you feel better.

Chronic tonsillitis is when you have tonsillitis that lasts for more than three months or keeps coming back. You may not have severe symptoms, but your tonsils may always be inflamed or infected.

This may have a negative impact on your quality of life and may cause other complications, such as breathing problems during sleep, pockets of pus or abscesses around your tonsils, or infections spreading to other parts of your body.


The Bacteria and Viruses that Causes Tonsillitis

Numerous types of bacteria and viruses can cause tonsillitis. Some of the common ones are:

  • Group A streptococcus (GAS) bacteria: These bacteria cause bacterial tonsillitis and strep throat. They can also cause scarlet fever, which is a rash that spreads over the body.
  • Epstein-Barr virus (EBV): This virus causes viral tonsillitis and infectious mononucleosis (mono). It can also cause a swollen spleen, liver problems or a rash.
  • Herpes simplex virus (HSV): This virus causes viral tonsillitis and cold sores. It can also cause genital herpes, encephalitis or meningitis.
  • Coronavirus (COVID-19): This is a new type of virus that causes respiratory infections. COVID-19 can also cause loss of taste or smell, cough, shortness of breath or other complications.

While Streptococcus (strep throat) and Epstein-Barr virus (mono) are the most prevalent bacteria or viruses that can cause tonsillitis, it can be caused by other viruses too such as Rhinoviruses, Influenza, Parainfluenza, and Enteroviruses.

These viruses can also cause symptoms such as the common cold, flu, croup, laryngitis (conditions that affect the upper airway, especially the voice box or larynx), hand, foot, mouth infection, pink eye, diarrhoea or pneumonia.


Symptoms of tonsillitis

The most common symptoms of tonsillitis include:

  • Sore throat: The most typical symptom of tonsillitis is a sore throat. It may be minor or severe. Swallowing can be a challenge with a sore throat.
  • Swollen tonsils: The tonsils are two tissue pads in the form of an oval behind the throat. When swollen, red, and white or yellow spots may be visible.
  • Fever: A bacterial infection is primarily to blame for the common tonsillitis symptom of fever.
  • Difficulty swallowing: The swelling of the tonsils can make it difficult to swallow, especially for children.
  • Bad breath: Tonsillitis may result in poor breath because of the bacteria causing the infection.
  • Other symptoms: Other symptoms of tonsillitis may include an earache, a stiff neck, swollen glands in the neck, and a headache.

If you have any of these symptoms, you must see a doctor to determine if you have tonsillitis and get the appropriate treatment.


How Tonsillitis is Spread?

Yes, tonsillitis is an infectious disease that can be transmitted when one person’s respiratory secretions come into contact with another person’s secretions. It means you can catch tonsillitis if you are near someone who has it and if he coughs or sneezes, releases droplets of saliva or mucus that contain the bacteria or viruses that cause tonsillitis.

You can also get tonsillitis if you touch your mouth or nose after touching something contaminated by an infected person, such as a doorknob, a toy, or a tissue. Another way to get tonsillitis is by sharing food or drinks with someone who has it or using utensils, cups, or straws that an infected person has used.


How to Prevent Tonsillitis?

While tonsillitis can be hard to avoid, you can lower your chances of getting it by following some simple steps:

  • Wash your hands frequently after using the restroom or touching your face or nose. It can help you get rid of any germs that may cause tonsillitis.
  • Avoid contact with people with symptoms of tonsillitis, such as a sore throat, fever, or swollen glands. If you must be around them, try not to share their utensils, cups, or towels. Avoid kissing or hugging people suffering from tonsillitis.
  • To stop an illness or lessen how bad the symptoms are, get a flu shot every year.
  • Teach your children to sneeze and cough properly by covering their mouths with a tissue or elbows. It can prevent them from spreading germs to others or themselves.
  • Keep your mouth and throat healthy by avoiding irritants like tobacco, alcohol, spicy, hot, or cold foods and beverages. These can dry out or damage the mucous lining of the throat and make it more prone to infection.
  • Drink plenty of water and use a humidifier or vaporiser to moisten your home or workplace air. It can help keep your throat hydrated.
  • Eat right, sleep enough and exercise to boost your immune system and overall health. It can help your body fight off infections and prevent tonsillitis

If you already have tonsillitis, stay home from work or school until you feel better. You may recover more quickly and avoid infecting others with tonsillitis. You should drink fluids, rest your voice, and gargle with salt water to relieve throat discomfort.


When to see a Doctor?

So, when should you consult a doctor, if you feel uncomfortable with your throat? You should meet a doctor if you experience:

  • A high fever of 100.4°F (38°C) or more, which can indicate a serious infection or a complication such as rheumatic fever.
  • A very sore throat that makes it hard to swallow, drink, or eat. It can lead to dehydration or malnutrition.
  • A stiff neck that limits your head movement. It may be a sign of meningitis, a life-threatening disorder that damages the spinal cord and brain’s surrounding membranes.
  • Swollen glands in the neck that feel tender or painful when you touch them. This can mean that the infection has spread to the lymph nodes, which help fight off germs.
  • An earache that occurs along with tonsillitis. This can indicate that the infection has reached the middle ear, which can cause hearing problems or damage to the eardrum.
  • Tonsillitis that lasts longer than two weeks or keeps coming back. It can suggest that you have chronic or recurrent tonsillitis, which may require surgery to remove the tonsils (tonsillectomy).

If you have a child under three years old with tonsillitis, you should see a doctor immediately if he/she feels discomfort in the throat, regardless of the symptoms. Young children are more likely to develop complications from tonsillitis, such as breathing difficulties, dehydration, or abscesses. Therefore, it is essential to get them treated as soon as possible.


How is Tonsillitis Diagnosed?

The diagnosis of tonsillitis is based on the physical examination of the throat and other diagnostic testing to determine the infection’s origin. The following are some examples of possible tests:

  • Throat swab: A sterile swab is used on the back of the throat to test for infections. Collecting a sample of secretions, which are then tested for streptococcal bacteria or other pathogens.
  • Complete blood count (CBC): A blood sample is analysed to check the levels of different types of blood cells and determine if the infection is viral or bacterial.
  • Monospot test: A blood sample is tested for antibodies to the Epstein-Barr virus, which causes mononucleosis (commonly called the kissing disease or mono is a viral infection that spreads through saliva), which can also inflame the tonsils.

Treatment of Tonsillitis

The source and severity of the infection determine the available treatments for tonsillitis. Some of the possible treatments are:

Antibiotics

If tonsillitis is a bacterial illness like strep throat, antibiotics are prescribed to kill the bacteria and prevent complications. Antibiotics are ineffective against viral infections and may induce adverse reactions such as nausea, diarrhoea, and allergies.

If your tonsillitis is caused by bacteria, you should take antibiotics to avoid getting sicker or having complications. Group A Streptococcus is the most typical bacterial cause of tonsillitis, which can cause rheumatic fever. This inflammatory condition can damage the heart and joints, or post-streptococcal glomerulonephritis, an inflammation of the kidneys that can impair their function.

Antibiotics can prevent these complications by killing the bacteria and stopping their spread. Antibiotics are usually taken for ten days to ensure complete eradication of the infection.

Pain relievers

Over-the-counter (OTC) medications such as acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) can help reduce pain, inflammation, and fever. Aspirin should not be given to minors under 16 due to the possibility of Reye’s syndrome, a rare but severe condition affecting the liver and brain.

Tonsillectomy

Surgery to remove the tonsils (tonsillectomy) may be recommended by your doctor if the tonsillitis is recurrent, chronic, or severe or causes complications such as breathing problems, sleep apnoea, or abscesses. Tonsillectomy is usually performed under general anaesthesia and may involve using a scalpel, a laser, or a heated device to cut or destroy the tonsils.

Tonsillectomy has benefits and risks that should be carefully weighed before deciding to undergo the surgery. The decision to have a tonsillectomy should be made in consultation with your doctor, who can assess your medical history, symptoms, and preferences and describe the surgery’s benefits and drawbacks.

Some of the possible benefits are:

  • Reduced frequency and severity of throat infections
  • Improved quality of life and well-being
  • Improved sleep quality and breathing
  • Reduced risk of complications from tonsillitis

Some of the possible risks are:

  • Bleeding during or after surgery
  • Infection at the surgical site
  • Reaction to anaesthesia
  • Pain and difficulty swallowing
  • Changes in voice quality
  • Regrowth of tonsil tissue

Home remedies

Some home remedies can also help soothe the symptoms of tonsillitis and provide you with much-needed relief from the symptoms. Some handy home remedies that can help you manage the symptoms:

  • Get lots of rest, and steer clear of demanding activities.
  • Drink a lot of water to keep yourself hydrated and avoid dehydration.
  • Avoid irritants such as cigarette smoke, alcohol, and spicy foods.
  • Use a humidifier or vaporiser to increase humidity in the air. This can help you in breathing and keep your throat moist.
  • Gargle with warm salt water several times a day to reduce inflammation and pain.
  • Suck on lozenges, ice chips, or popsicles to numb and soothe the throat.
  • Eat soft or cold foods that are easy to swallow and do not irritate the throat.
  • Use over-the-counter analgesics like acetaminophen or ibuprofen as directed by your doctor.
  • Seek medical assistance if your symptoms worsen or do not improve within a few days.

There is no accurate way to eliminate tonsillitis perfectly. Still, you can reduce your risk by constantly avoiding direct contact with sick people, cleansing your hands, getting a flu shot yearly, and teaching your children to cover their mouths and noses when they sneeze or cough.

Talk to your doctor if you are worried about getting tonsillitis or if your tonsillitis is very bad or doesn’t get better in a few days. Timely intervention can prevent major ailments in the future.
