Do you also secretly swallow food and drink? Let's talk about Silent Aspiration!

It's normal to choke a little when we eat or drink. But did you know that sometimes things like food and drink can sneak into our airways without us even noticing any coughing or discomfort? That's what we call "silent aspiration." This is something to be careful about, especially for parents of young children.

What is Silent Aspiration?

Simply put, ``Silent Aspiration`` is when you unintentionally inhale food, drink, saliva, or stomach acid into your windpipe (trachea). Normally, when we swallow, the nerves and muscles in our mouth and throat work together to push the food straight into the stomach, rather than into the windpipe. There is a small flap at the top of our throat called the ``Epiglottis``. When we swallow, this flap closes, covering the windpipe. So when these nerves, muscles, and the ``Epiglottis`` are working properly, the food goes into the stomach and air into the lungs.

But a person with ``Silent Aspiration'' does not cough or feel that these things have gone into the windpipe. That is why the word "silent" is added to it. In this way, not only food, drink, and saliva, but also for some people, stomach acid (acid that comes up into the throat in conditions like gastritis - ``Acid Reflux'') can secretly go into the windpipe.

What does this do to the body?

The occasional small object that gets stuck in the airway may not be a big problem. Most of the time, our bodies cough it out.

But if you have ``Silent Aspiration'', you may not realize it's happening or how often it's happening. If you keep getting fluids into your airways like this, you can develop a condition called ``Aspiration Pneumonia'', which is an infection in your lungs. If not treated properly, ``Aspiration Pneumonia'' can be very dangerous.

What are the symptoms of silent aspiration?

People with ``Silent Aspiration'' may not show any symptoms. However, if there are symptoms, they may vary depending on your – or your child's – age. Young babies with ``Silent Aspiration'' may show symptoms such as:

• Your breathing rate increases or you catch your breath while breastfeeding.
• You often get a slight fever for no reason, or you develop infections in the respiratory system, especially the lungs.
• They don't like to drink milk, turning their face away from the bottle or breast milk.
• After drinking milk, there is a "wet" sound in the voice, as if there is mucus in it, or a sound like that when crying.

Older children and adults may experience the following symptoms if they have ``Silent Aspiration'':

• Breathing rate increases when eating.
• I feel like something is stuck in my throat.
• Toddlers say they can't eat and refuse.
• My nose gets stuffy after I finish eating, but it goes away after a while.
• There is a rattling sound for no reason, and a noise when breathing.
• After eating, the voice changes as if there is mucus in the throat.
• Respiratory infections like bronchitis often occur.

What causes this?

There are many reasons why ``Silent Aspiration'' can occur. Sometimes it can happen for no apparent reason and it can happen by chance. But most often it is seen in people who have a medical condition that interferes with the swallowing process. For example:

• Cleft lip or cleft palate.
• Difficulty swallowing (Dysphagia) or vocal cord paralysis.
• Gastroesophageal Reflux Disease (GERD). People with this condition can unknowingly allow stomach acid to flow up into the windpipe.
• A condition called ``Laryngomalacia.`` This affects the baby's larynx (voice box), and can cause difficulty swallowing and increase the risk of ``GERD.``
• Problems related to the brain and nervous system. For example, conditions such as Cerebral Palsy, Multiple Sclerosis (MS), seizures, or a previous brain injury or stroke.
• Tubes placed down the throat due to other medical conditions. For example, a nasogastric tube or a tracheostomy tube.

Who is at higher risk of developing this?

This condition called ``Silent Aspiration'' can affect anyone from small babies to the elderly. But let's look at who is most at risk:

• Young babies: Babies can't tell you that they have a sore throat or are having difficulty eating. So it's hard to tell if they have ``Silent Aspiration''. Also, since they often eat liquid foods, it's easier for liquids to get into the airway than solid foods.
• People with chronic illnesses or disabilities: Many illnesses, such as multiple sclerosis (MS) or epilepsy, can affect your ability to swallow. These health conditions that affect swallowing increase the risk of silent aspiration.
• Elderly people: Conditions such as dementia and stroke are common in old age. These can cause changes in swallowing patterns and may make you unaware that something is stuck in your throat.

How do you recognize this?

When diagnosing silent aspiration, the first thing your doctor will usually do is examine your nose, mouth, and lungs and discuss your medical history. If your baby has these symptoms, your doctor will likely start with the same tests.

If necessary, the doctor may order some tests to look inside your throat and check how you swallow. You or your baby may need to have tests like these:

• Chest X-ray: This is a painless test. It takes pictures of your lungs and chest. It can check for pneumonia in the lungs and can also look at things in your throat and respiratory system.
• Fiber-optic Endoscopic Evaluation of Swallowing (FEES): In this test, the doctor inserts a thin tube with a camera attached through your nose. This can see inside your throat as you swallow. Sometimes, you may be given a special liquid to drink to help see what you are swallowing clearly.
• Laryngoscopy: In this procedure, the doctor looks at your throat with a thin tube equipped with a camera.
• Upper GI series: Before this X-ray, you will be given a liquid (barium) to drink, which shows up on the X-ray. This can help find problems in the digestive system that can cause conditions like GERD.

How is this treated?

When treating ``Silent Aspiration'', the first thing to do is to treat the underlying condition that caused it. For example:

• If you have GERD, your doctor may prescribe medication to stop stomach acid from flowing up into your throat.
• If your baby has mild aspiration while breastfeeding, your doctor may recommend that you hold your baby in an upright position while feeding. This upright position can help your baby swallow breast milk or formula more easily.
• Babies who frequently choke on breast milk or formula may need a modified diet with thickened feeds. If the condition is severe, they may need to have a temporary feeding tube inserted through the nose or stomach. Usually, doctors remove the tube when the baby is able to swallow well.
• A person with a cleft lip or palate can swallow normally once it is surgically repaired.

After treating the underlying cause, your doctor may perform further tests to see if your swallowing ability has improved.

Can Silent Aspiration be prevented?

There is no clear way to prevent ``Silent Aspiration''. But you can keep yourself and your baby healthy by regularly seeing your doctor and getting checked. If you have any doubts about your health or your baby's health, talk to your doctor. Your doctor is there to prevent health problems and provide treatment when needed.

The most important thing is to talk to a doctor if you have any doubts, even the slightest.

What happens if I have (Silent Aspiration)?

In babies, ``Silent Aspiration'' may go away on its own as they grow older. However, if your or your baby's symptoms are caused by a specific medical condition, the first step is to find out what the cause is.

If the cause is treated properly, ``Silent Aspiration'' can often be cured, and you can live a healthy life. Ask your doctor if you need to see him regularly to check on your condition.

When should I see a doctor?

If your baby has symptoms of choking, or if you think your baby may have ``Silent Aspiration,'' see your baby's doctor right away. Also, check your baby's weight and go for health checks as recommended by your doctor. This can also help ensure that your baby is getting the nutrition they need.

If you have symptoms of GERD or difficulty swallowing, make an appointment to see a doctor. By getting the right tests and treating your health conditions, you can prevent silent aspiration and other complications.

When should I go to the Emergency Department (ETU) ?

Seek emergency medical attention immediately if your baby has any of the following:

• If the skin turns blue.
• If you have difficulty breathing.
• A fever of over 100.4 degrees F (38 degrees C) if the baby is less than 3 months old, or a fever of over 102.2 degrees F (39 degrees C) if the baby is between 3 months and 3 years old.
• If it is difficult to wake up from sleep.

If you have any of these symptoms, seek emergency treatment immediately:

• If you can't swallow normally.
• If you feel like you're having trouble breathing or suffocating.
• If you have chest pain.
• If you feel like food or something is stuck in your throat or windpipe.

Silent aspiration can be a scary thing, especially if it affects your baby. But the good news is that silent aspiration can be controlled or cured by treating the underlying cause. As your baby's nerves and muscles grow and learn to work together, it sometimes gets better on its own. Whatever the cause, your doctor is there to help you get the tests and treatment you need. Talk to him or her about your concerns. Then, you can make a plan to help you and your baby live a healthy life.
