When a persistent cough could be something more

An occasional cough is normal — it helps clear irritants and secretions from your lungs and prevents infection. However, a cough that persists for weeks is usually the result of a medical problem.

When someone experiences a persistent cough, it is more than a minor annoyance. In fact, it can leave you exhausted. It may keep you from sleeping, cause headaches or, in some cases, make you vomit or cause rib fractures.

Coughing is seen in many medical conditions, so it can be difficult to pinpoint the trigger. The most common causes of cough for nonsmokers are postnasal drip, asthma and gastroesophageal reflex disease (GERD), also known as acid reflux. However, there are times when a persistent cough could be a sign of something more serious.

When to see the doctor for a persistent cough

You should see your doctor if your cough lasts for weeks and affects your sleep, school or work. You should especially seek medical treatment if you're coughing up blood or excessive mucus.

To get the right diagnosis and treatment, take note of how long the cough has lasted, the type and features of the cough, plus any other health symptoms you are experiencing.

Talk to a doctor if you’re experiencing other symptoms, like:

• Fever, especially if it's high or prolonged
• Excessive mucus production
• Coughing up blood
• Shortness of breath
• Weight loss
• Weakness, fatigue, loss of appetite
• Chest pain that's not caused by the cough itself
• Night sweats
• Wheezing

One common cause of chronic coughing is COPD

Across the United States, nearly 12 million people have chronic obstructive pulmonary disease, also known as COPD. COPD is a lung disease that makes breathing difficult. Smoking is the most common cause of COPD, accounting for as many as 9 out of 10 COPD-related deaths. However, nearly 30 percent of people who have COPD have never smoked.

There are two main types of COPD:

• Chronic bronchitis is a long-term cough with mucus, caused by the inflammation of the bronchial tubes.
• Emphysema is the thinning and destruction of air sacs in the lungs, making breathing more and more difficult.

People who have COPD:

• Become short of breath while doing everyday activities they used to do with ease.
• Produce too much mucus.
• Cough frequently, or constantly.
• Wheeze.
• Feel like they can’t breathe.
• Are unable to take a deep breath.
• May be at a greater risk of heart failure

If you have COPD or any of its symptoms, you should see your primary care provider for treatment.

Relieve your COPD symptoms with deep breathing exercises

Certain breathing exercises can help people who have chronic lung diseases like COPD or asthma. These techniques are also helpful for people with anxiety or to simply calm your thoughts and emotions:

• Diaphragmatic. Inhale through the nose, letting your belly fill with air. Exhale through the mouth, at least twice as long as it took to inhale. Repeat for five minutes, three or four times a day.
• Pursed lip. Inhale through the nose, exhale at least twice as long through the mouth, with lips pursed. This technique is especially effective for people with COPD and asthma.
• Equal breathing. Inhale through the nose for five seconds, then exhale through the nose for five seconds. As you continue this progression, increase the number of seconds according to your comfort level.

A chronic cough turned out to be more for one Wellmark member

Gail Orcutt of Altoona, Iowa, was diagnosed with radon-induced lung cancer after suffering from an annoying, persistent cough and wheeze.

"At my first appointment, the provider I saw gave me a breathing treatment and some kind of asthma medicine. However, I continued to have symptoms, so I made another appointment to see my primary doctor. He ordered tests that led to my diagnosis and saved my life. My advice is, if you continue to have symptoms after treatment, be persistent. If you don't see improvement, see your doctor again," said Orcutt.
