CAUSES OF DRY COUGH
Basically, dry coughs are caused by viral infections. In most cases, they are the same viruses that cause flu and colds. A cough is classified as dry if it occurs without any phlegm discharge. What causes a dry cough in one individual may not cause a dry cough in another, depending on many factors. However, the causes of dry cough are numerous such that, every person may get infected with some form of a dry cough somewhere some time in their life. There are factors that may trigger a constant dry cough which may also trigger a dry cough at night. There are some that may only result in an acute dry cough or a persistent dry cough or both. Let’s take a look at some of these causes.
1. MEDICINAL SIDE EFFECTS
Medicinal side effects are well noted among the various dry cough causes. The guiltiest of such drugs are heart related and blood pressure drugs. If you realize that you began coughing after two or three days of taking in a medical drug, the drug could be the cause. Such coughs are usually dry and may develop into a constant dry cough for as long as the medication is maintained. ACE inhibitors and beta-blockers for treatment of high blood pressure are proven to cause a chronic dry cough among some patients.
- COMMON COLD AND INFLUENZA: Dry coughs usually occur after a flu or cold infection. Though the cold may be gone, the damaging effect of the virus in the lungs and larynx may lead to a persisting dry cough until the inflamed tissues are healed.
- GERD: Gastroesophageal reflux diseases are guilty of dry cough at night. While asleep, people with these diseases suffer a reflux of stomach acid into the lungs. Inflammation by the acid may cause bouts of cough during the night. A long standing and untreatable GERDcan also lead to a chronic dry cough.
- ASTHMA: Asthma is no innocent one. This sickness creates difficulty in breathing – the wind pipe may be closed or narrowed, causing the patients to choke. This then leads to a dry cough.
- TUBERCLOSIS: This is one of the most dreaded respiratory diseases. In the initial stages, they are symptomatic of a constant dry cough before they graduate into wet coughs which may be accompanied with blood stained phlegm.
- CONGESTIVE HEART FAILURE: This medical condition is known to causedry coughs at night and a persistent dry cough.
3. CIGAR SMOKING
It is common knowledge that cigarette smoking causes coughing. The associated cough is usually a dry one. They may lead to further lung problems such as a lung cancer which exhibits even severe dry cough symptoms.
4. POST NASAL DRIP
Post nasal drips usually cause coughs. No wonder people also experience periodic coughs when they have flu or colds. Frequent nasal drops into the lungs may lead to a persistent dry cough or an acute night dry cough.
5. CHOKING BREATH AND DRYNESS IN THE LUNGS
Without any sickness, a dry cough may be triggered by a choking breath or breathlessness. Just like the asthmatic mechanism, any condition like a stampede, concentrated smoke in air from a fire, neck strangling etc, which causes people to suffocate can cause an acute or temporal dry cough. Eating food in large quantities or gulping huge volumes of water may choke the lungs or air passages and can also lead to a dry cough.
6. FOREIGN SUBSTANCE INHALATION
Inhaling of foreign objects or chemical toxins may cause the body to react. This leads to a reflexive cough. People living in industrial areas may experience a dry cough that is constant and experience bouts of dry cough at night due to the influx of toxins from the environment.
Most people don’t know that an allergy is what causes a dry cough. A dry cough may be triggered by an allergy or an allergic reaction. Most people have some form of either strong or mild allergy to dust, fumes, pet fur etc. Such allergies are among causes of dry cough.
- Hay Fever is a common example of an allergen dry cough trigger. This is a tree and grass pollen allergy. Allergic people who live nearby or in communities with lots of trees and grass may develop a chronic dry cough.
Now that you know these dry cough causes, you should take extra steps towards finding out how to treat them.
