Causes of dry cough

Environmental factors and lifestyle

  • Pets allowed
  • Cigarette Smoke
  • Low humidity
  • Exposure to environmental pollutants
  • Changes in air conditioning temperature.
  • Exposure to  tobacco or chemicals

 

 

Diseases

Medicines

Side effects of certain medicines against high blood pressure , including:

  • The ACE inhibitors ,
  • Angiotensin II receptor antagonists (ARA II).

 

Cough at night

Respiratory infections are one of the most common causes of coughing at night. An improper position and heavy dinner may cause gastroesophageal reflux which can cause a persistent cough.

 

Other causes

 

Dry cough in children

Generally, dry cough in children has a non-serious origin.

Why do children have dry cough? 
Factors that can cause dry cough in children may be:

  • Viral infections such as colds and flu
  • Breathe dry and warm air
  • Nasal discharge
  • Laryngitis
  • Exposure to environmental allergens or irritants
  • Asthma (causes chronic dry cough)
  • Whooping cough (causes dry cough that lasts for months)
  • Gastroesophageal reflux
  • Pneumonia (especially in school-age children)
  • Interstitial lung disease (less common in newborns and infants)

If the newborn suffers from a cough, it is best to go to the pediatrician for a consultation.

 

Dry cough in the morning

Causes of dry cough in the morning

Smokers
This is perhaps the most common reason for coughing in the morning every day. In extreme cases, the person who smokes may cough up blood in the morning.

Traces of blood with dry cough may be caused by:

  • Rupture of weakened bronchial capillaries,
  • Changes in pulmonary veins and arterioles,
  • Strange body.

When the person stops smoking , for a variable period it is possible to have a cough (also with catarrh or productive) more intense than before.

Asthma
Asthma is a chronic inflammatory disease that affects people of any age, even small children.
There are inhalers to reduce the symptoms.

postnasal otejamento
The mucus in the sinus slowly descends behind the rear area of the throat and thus causes irritation.
Since the mucus goes back, this disease worsens when the person is lying down, causing coughing when waking up.

Gastroesophageal Reflux
This is a disease that can cause chronic coughing at night and in the morning.
Acid reflux rises unexpectedly and is difficult to resolve.
This disease can also cause:

Medication Medications
used for high blood pressure (ACE inhibitors and angiotensin II receptor antagonists) can cause dry cough that can become constant in the morning.

COPD (Chronic Obstructive Pulmonary Disease)
The first sign of COPD is coughing every day in the morning. This lung disease is characterized by:

It is characterized by the excessive production of mucus and phlegm that causes the narrowing of the airways; the consequence is a lower oxygen flow.
The patient coughs to release the airways that are filled with mucus.
Coughing can be:

  • With catarrh ,
  • Dry: when the phlegm does not go out.

 

Persistent and chronic dry cough   

Those who suffer from cough for a long period of time may have chronic dry cough.

Reasons for cough that does not go away

  • One of the causes of very frequent chronic cough is the back nasal drip. When a person suffers from sinusitis, colds or any allergy, the substance produced by the nose trickles down the back of the throat.
  • Asthma is one of the reasons that causes continuous dry cough.
  • Another cause is gastroesophageal reflux which causes irritation of the throat and even the lungs.
  • Sometimes dry cough may be caused by the administration of certain medications, particularly ACE ( angiotensin converting enzyme ) inhibitors .
    Generally these medications are indicated for patients suffering from kidney disease, heart disease and hypertension .
  • Another cause of continuous dry cough is lung cancer.

 

Cough after eating

A cough after a meal can be caused by several reasons.

Dry cough

Causes
Sudden coughing can be a reflex action caused by some ingested food particles that clog the airways.
Among the diseases that cause cough after meals are:

Allergies and infections
Some people are allergic to certain foods and have coughs after eating these substances.
There is an immune response that causes the cough immediately after eating.

Infectious diseases of the larynx and esophagus can lead to temporary dysfunction of the organ in question and, therefore, difficulty in swallowing food and drink. The consequence may be suffocation.
This situation can cause coughing regardless of the food that the person eats.

The  gastroesophageal reflux disease is caused by malfunction of the lower esophageal sphincter.
After the person has eaten, the sphincter is not able to hold the food and acidic digestive juices of the stomach.
Thus, a portion of the contents of the stomach is pushed back into the esophagus.
This can cause coughing.

Gastroesophageal reflux also causes heartburn.

In case of reflux it is recommended:

  • Keep the head higher than the stomach when the person lies in bed,
  • Do not drink after meals,
  • Avoid or reduce foods that are digested slowly, especially meat,
  • Avoid combinations of incorrect foods that slow down digestion, such as proteins and carbohydrates together (for example, rice and beans).

Zenker esophageal diverticulum

Another illness is the esophageal diverticulum of Zenke , in which a part of the esophagus protrudes and causes the cough after a meal.

The dysphagia is a disorder that prevents people from properly swallow food.
The patient’s esophagus does not function properly due to:

  • An obstruction,
  • Peristalsis (contractions of the muscles of the digestive tract) absent or too weak to move the food.

For these reasons there is a sensation of obstruction in the throat.
This causes the cough every time the individual eats something.
