8 Causes of Persistent Flu and Cough
There are many reasons for a prolonged cough and cold. From allergies and weather changes to infections caused by a weak immune system, our surroundings can be the cause of coughs and colds that just won't go away.
Through this article, we will delve deeper into what might be happening within the body, keeping in mind that coughs and colds can be a sign that something is wrong. Also, discover solutions to help alleviate these symptoms.
1. Post-Viral Infection

Why does a cough not heal? A viral infection could be the culprit. Generally, this cough occurs up to two months after a viral infection takes place. The causes can vary.
However, the most common is nasal mucus dripping and flowing down to the throat. Additionally, this viral infection also causes inflammation in the respiratory tract.
When night falls, the cough becomes more severe. This happens because the reclining position causes mucus to flow to the back of the throat and lungs, leading to inflammation. It is no wonder that this type of cough disrupts the sufferer's quality of sleep at night.
2. Allergies and Asthma

Dust, pollen, pet dander, and other allergens can trigger allergic reactions that cause coughs and flu-like symptoms. But a cough due to allergies is often closely related to allergic rhinitis.

This is a condition where environmental allergens cause symptoms such as a runny nose and throat irritation, leading to a persistent cough. Certain types of asthma also present a cough as a primary indication, which is exacerbated by the immune system's response to allergens.
If these two conditions occur together, the allergic reaction will affect the respiratory tract more severely. As a result, the cough does not subside, and the patient finds it increasingly difficult to breathe.
3. Bacterial Infection

Bacterial infection can also be the mastermind behind a cold and cough that won't go away. Protracted bacterial bronchitis (PBB), for instance, is a specific example that commonly occurs in children. Not only will there be a wet cough, but the patient will experience fever, chills, and sometimes difficulty breathing.
This chronic wet cough does not respond to various bacterial infection treatments, thus requiring antibiotics to relieve the symptoms.
4. GERD

GERD, or gastroesophageal reflux disease, does not just cause physical discomfort. This disease can also cause a cough that refuses to heal because stomach acid can rise up to the throat.
Stomach acid that comes into contact with the throat causes irritation and triggers a chronic cough. To manage this condition, those suffering from a cough due to GERD may use proton pump inhibitors.
5. Weather Changes

Weather changes are often the culprit behind long-lasting flu symptoms. Fluctuating temperatures from warm to cold, or vice versa, challenge our immune system, making the body more susceptible to the viruses that cause the flu and coughs.
The low humidity that occurs during cold weather also makes the respiratory tract drier. The result? This tract becomes prone to irritation and triggers a cough.

6. Neurogenic Conditions

In some cases, an unexplained cough may be the result of increased nerve sensitivity—a condition called a neurogenic cough. To soothe and treat this type of cough, some studies suggest gabapentin and amitriptyline.
7. Exposure to Environmental Irritants

Why won't the cough go away? Exposure to environmental irritants such as smoke, gas, and dust might be the trigger. First, these irritants can trigger a cough reflex directly by activating sensory nerve fibers in the respiratory tract.
Additionally, these irritants can cause oxidative stress and eosinophilic inflammation, which further irritates the respiratory tract and prolongs coughing symptoms.
This condition is exacerbated by air pollution, especially in high-pollution areas in Asia, which has been identified as a major risk factor for chronic coughs.
8. Lifestyle

The lifestyle you adopt apparently also contributes to coughs and colds. Besides GERD, smoking habits have a major impact in causing chronic coughs that do not go away.
Not only being a smoker, but spending days in environments with secondhand smoke exposure is also a major risk factor for this condition. This happens because the inhaled smoke dries out the mucous membranes and irritates the respiratory tract.
The result? This condition has the potential to trigger long-term lung problems. Lifestyle changes are needed to cure this condition, in addition to taking medications recommended by a doctor.
