Bronchioles are essential air passages that carry air from your nose or mouth to the lungs.  Blockages in this part of the Respiratory system may lead to severe breathing problems.

When microbes attack the body, the antibodies in our body fight these germs.  Mucus production Increases and clogs the Bronchioles and leave very less room air to move in and out.

Bronchitis occurs when these airways are blocked or inflamed due to the presence of high levels of mucus.  Hence, you may experience severe coughing and sometimes, chest pain.

Is Bronchitis Viral or Bacterial:

Read on to know the answer to this question. Bronchitis is again of two types:

Acute Bronchitis:

This type of Bronchitis is common, and the symptoms remain for few weeks.  The symptoms may not appear after that period.  Acute Bronchitis occurs most commonly due to a viral infection. It creates great inconvenience. But, it usually disappears, the way it came, without any fuss.

Chronic Bronchitis:

Chronic Bronchitis is more severe and may lead to Chronic Pulmonary Obstructive Disease (COPD).  This condition is caused by Bacterial infection.  Chronic Bronchitis is a long-term phenomenon, and it is ubiquitous in people who smoke.

Bacterial Bronchitis is chronic, and it is always advisable to see the doctor at the earliest.

What Bacteria causes Bronchitis:

There are many varieties or strains of Bacteria that cause Bronchitis.  Some of the common ones are Moraxella catarrhalis, Mycoplasma pneumonia, Bordetella pertussis, Haemophilus influenzae and Streptococcus pneumoniae,

8 Causes of Bacterial Bronchitis:

The reasons for Bacterial Bronchitis is any:

Weak immune systems:

Immune systems are usually vulnerable, especially in young kids and older individuals.  Studies show that Bronchitis is very common among children between six months and two years.  This could turn severe and may require hospitalisation, especially in the winter season.

People taking treatment for other diseases also have weak immune systems and are prone to Bacterial Bronchitis


Smoke irritates the lungs.  When inhaled by a smoker or a non-smoker, the antibodies of our immune system start producing mucus in excess causing Bronchitis.

This is one of the biggest reasons for Bacterial Bronchitis.

Working in coal mines or  working with farm animals

People working in coal mines are exposed continuously to suspended particles.  These particles cause chronic bronchitis as they get into the airways blocking free entry of air to and fro the lungs.

People working with farm animals face similar problems; this is because they are regularly exposed to pet dander and suspended moles and mites in the air around the farm.

Air pollution:

Air pollution has become the number one cause of most respiratory problems today.  This problem is severe if you are living in a city where smoke, dust particles, dust particles and smog are ever present in the air.

Factories and establishments pollute the air by releasing fumes of strong acids, ammonia, chlorine, bromine, organic solvents and sulphur dioxide.  These fumes cause severe damage to the lungs and may lead to Bacterial Bronchitis.

Primary Viral Infection:

Say, you are already suffering from a viral infection In the Trachea, Bronchi or Bronchioles.  This is an excellent opportunity for Bacteria to make easy inroads into the respiratory system causing Bacterial Bronchitis.

Dietary Deficiency:

Sometimes Dietary Deficiency can also cause this type of Bacterial Bronchitis.  Deficiency of Vitamin D3 can be one of the causes for the occurrence of COPD and other respiratory diseases like Asthma.

Some studies show that lack of Vitamin B12 causes nervous dysfunction problems.  This may lead to an incessant cough.

An incessant cough could also indicate respiratory problems like Bronchitis. It has been seen that prescription of B12 supplements has been successful to a certain extent in suppressing these respiratory problems.


People with Allergies have higher chances of getting Bacterial Bronchitis. The connection between the two may not be direct.

The allergens like moles, mites, pet dander, pollen and dust damage the immune system.  Our body defences turn produces mucus to combat them.  The mucus is produced in excess clogging airways and causing severe Bronchitis.

Winter Season:

Winter season is the worst season for people with respiratory problems.  The nip in the air causes it to become dry.  Our nose is unable to warm the air for breathing, and thus various illnesses like sinusitis and Bronchitis are bound to follow.

Avoiding Vaccinations:

A vaccination for Bacterial Bronchitis is yet to be found.  But some vaccinations treat other respiratory illnesses.

If these illnesses are not decreased, the body becomes less immune allowing Bacteria to enter the body and cause Bacterial Bronchitis easily.
