Belly breathing, flared nostrils and wheezing. These are a few signs of chest congestion that make the baby uncomfortable and the parents anxious. Chest congestion is often due to excess mucus in the chest, but could also develop due to other health issues that need a doctor’s intervention.

In this post, MomJunction tells you about chest congestion in babies, its causes, symptoms, and how to handle the situation at home.

What Is Chest Congestion?

Chest congestion is the accumulation of excess mucus in the lungs, bronchi, and the trachea. Mucus works like the first line of defense for the body. The respiratory system is lined with cells that produce sticky mucus, which traps pathogens and other foreign bodies (1). The upper respiratory system produces more mucus if it detects a pathogen or a foreign body. This excess mucus blocks the airway and leads to chest congestion.

Chest congestion is thus a symptom of an infection or the entry of a foreign body. And the chest congestion itself displays several other symptoms.

What Are The Symptoms Of Chest Congestion?

A baby with chest congestion might display the following symptoms:

  1. Coughing: A chronic wet cough is an indicator of mucus accumulation in the lungs. The baby would make a crackling sound while coughing, indicating that there is mucus turning out from the chest with each cough.
  1. Excessive mucus in the mouth: The baby will also cough out phlegm into their mouth. Phlegm is the mucus exclusively produced by the respiratory system. Coughing out phlegm is the body’s way of ridding itself of pathogens and other microbes (2).
  1. Wheezing: You are likely to hear the baby wheeze while breathing as the airways get blocked due to the inflammation of the airways and the accumulation of mucus. The wheeze will sound like a faint whistle, a wind passing through a tunnel or a sound from a squeaking toy.
  1. Poor appetite: The baby may not want to eat and lose their appetite.
  1. Fussiness: Constant chest congestion and troubled breathing will make the baby feel irritated and cranky.

Chest congestion is itself a symptom of an upper and/ or lower respiratory system infection or problem. The signs of chest congestion in a baby can vary depending on the underlying cause.

When To See A Doctor?

See a pediatrician when the baby displays the following symptoms:

  • Fever; temperature above 100.4°F (38°C)
  • Lethargy and constant drowsiness
  • Loss of appetite for over a day
  • Swelling of the face, neck, or eyes
  • The baby has difficulty breathing

The doctor will diagnose chest congestion by listening to the baby’s breath. The underlying cause can be determined through blood and sputum test. There are several reasons why an infant could develop congestion in their chest.

What Causes Chest Congestion In Babies?

The following are the main reasons why an infant could develop chest congestion:

  1. Infection: Pathogens can trigger the excess production of mucus by the body. A common infection that can cause congestion is the common cold. Several pathogens, such as the respiratory syncytial virus (RSV), can cause cold-related chest congestion among babies (3).
  1. Allergy: Allergies can also lead to excess secretion of mucus in the upper and/or lower respiratory system. Allergies, such as asthma and allergic rhinitis, cause excess secretion of mucus in the lungs (4).
  1. Exposure to an irritant: Inhalation of an irritant like smoke or dust can also cause an infant to have a congested chest (5).
  1. Genetic ailments: Some genetic diseases, such as cystic fibrosis, can cause the body to produce more mucus naturally. Infants with conditions such as cystic fibrosis have more than normal secretion of mucus in the lungs (6).

The treatment of chest congestion depends on the underlying cause.

How Is Chest Congestion In Babies Treated?

Chest congestion in infants is cured by treating the problem that caused it. Antibiotics and expectorants are sometimes used to treat chest congestion. Expectorants loosen mucus but they are not used for babies younger than two years.

Management of the viral infection, allergy, and genetic diseases are other ways to treat congestion. Viral infections cannot be treated with antibiotics but go away in time as the immune system gets stronger. Also, allergies and genetic diseases are persistent and can last a lifetime. Efficient management is the key to prevent them from causing any inconvenience to your baby.

Consult a pediatrician for the right treatment and avoid self-medication. However, you may try a few home remedies to ease a baby’s chest congestion.

Home Remedies For Chest Congestion

You may consider the following home remedies for chest congestion in babies:

  1. Increase the number of feeds to give the baby more fluids, as it helps loosen the mucus and keeps the baby hydrated. Babies with chest congestion may feed less than usual. While breastfeeding, take care to avoid aspiration that increases chest congestion particularly in infants.
  1. Give more fluids: Provide small sips of water to babies older than six months. Water, just like other fluids, can help loosen the mucus in the chest (7). You can also give liquid food items such as vegetable broth and thin purees to a baby, who is on a solid diet.
  1. Cool-mist humidifier: A humidifier is a device that pumps water vapor into the air. Humidity in the room helps break down the mucus and makes breathing easy for the baby. It can also help moisturize the upper respiratory system. Only use a cool-mist humidifier and not a steam/hot-mist humidifier as the latter can pose the risk of burns (8).
  1. Raise the infant’s head for some time: Let the baby rest in your lap with their head slightly raised. It will cause the mucus to dribble and settle downwards in the chest, thus helping the baby breathe and sleep better. If your baby is older than 18 months, then you can use a pillow to raise their head. Avoid using a pillow for a baby younger than 18 months (9).
  1. Tapping the back: Place the baby in your lap such that their back faces you. Support their body with one hand and with the other hand gently tap their back between the shoulder blades. Keep tapping gently for a few seconds to loosen the thick mucus and make breathing easy.

If the baby has cystic fibrosis, then they will need a distinctive, rhythmic style of tapping with a cupped hand. A doctor or a specialist in cystic fibrosis patient care can teach you the right way of tapping, depending on the age of the baby and the severity of their condition.

  1. Use a baby rub: You can apply Vicks BabyRub or any other baby safe cold ointment on the chest and back before the baby’s bedtime. This helps loosen the mucus and also soothes the baby.

The above home remedies can work in tandem with the medical treatment suggested by the doctor. Medical treatments and home remedies will help the baby feel better, but prevention is always better than cure.

How To Prevent Chest Congestion In Babies?

Preventing chest congestion in infants is about avoiding everything that causes excess mucus accumulation in the chest. Below are the preventive measures you can take.

  1. Maintain hygiene: Keep the baby’s surroundings clean and maintain hygiene when handling them or their items. Older infants and toddlers should wash their hands after playing outdoors. If someone in the family has flu or cold-like symptoms, they must avoid contact with the baby to prevent the spreading of the pathogen.
  1. Be aware of allergies and genetic diseases: If you know your baby has allergies, then keep them away from the allergen. Infants with genetic ailments like cystic fibrosis require routine care to prevent chest congestion.
  1. Follow vaccination schedule: A lot of diseases that cause chest congestion can be prevented through immunization. Stay up-to-date with your baby’s vaccination shots.
  1. Protect the baby from irritants: Smoke from automobiles and cigarettes are potential irritants for the upper respiratory system. Avoid taking the baby to places where they could be exposed to air pollution. Do not let anyone smoke in the house since even small quantities of tobacco smoke can irritate the baby’s lungs.

Chest congestion can make the baby miserable. However, with proper home care and management, the baby can recover soon. Also, try and prevent conditions that cause chest congestion to avoid any discomfort to the baby. Simple steps can prevent the accumulation of mucus and let the baby breathe easy.
