What Could Cause Wheezing?

Wheezing is a high-pitched whistling sound made while you breathe. It’s heard most clearly when you exhale, but in severe cases it can be heard when you inhale. It’s caused by narrowed airways or inflammation. Wheezing may be a symptom of a serious breathing problem that requires diagnosis and treatment.

Causes of wheezing

Asthma is the most common cause of wheezing. However, there are many other potential causes for wheezing. Before you can stop your wheezing, your doctor must first determine its cause. Wheezing may also be an indication of:

• chronic obstructive pulmonary disease (COPD)
• emphysema
• gastroesophageal reflux disease (GERD)
• heart failure
• lung cancer
• sleep apnea
• vocal cord dysfunction

Wheezing may be triggered by short-term illnesses or health emergencies. These include:

• anaphylaxis
• bronchiolitis
• bronchitis
• inhaling a foreign object
• pneumonia
• reaction to smoking
• respiratory tract infection

Anaphylaxis is a medical emergency. You should call 911 if you begin to experience dizziness, swollen tongue or throat, or trouble breathing.

Risk factors for wheezing

Wheezing can happen to anyone. However, there are certain risk factors that can increase your chances of developing a wheeze. Hereditary illnesses, such as asthma, can run in families. Wheezing can also occur in:

• people with allergies
• people with cancer
• children in day care
• past and current smokers

Controlling risk factors, such as smoking, may help improve wheezing. Avoid triggers, such as pollen and other allergens, if they make you wheeze. Some factors are out of your control, so the goal is to treat your symptoms to improve your overall quality of life.

When to seek medical help

Tell your doctor when you experience wheezing for the first time. Your doctor needs to know if you’re wheezing and having difficulty breathing, if your skin has a bluish tinge, or if your mental state is altered, even if it isn’t your first bout of wheezing. Seek emergency medical care if you’re wheezing while having difficulty breathing or experiencing hives or a swollen face or throat.

Treatment for wheezing

Treatment for wheezing has two goals. First, inflammation in your airways must be controlled. Prescription anti-inflammatory medications can decrease inflammation and excess mucus in your airways. These typically come in the form of inhalers, but they’re also available as long-acting tablets. Syrups are used for young children.

The second step is to open up your breathing tubes with quick-acting medications. Bronchodilators are often used to treat wheezing and help relieve a cough. They work by relaxing the smooth muscles that encircle your breathing tubes. Your doctor might recommend both anti-inflammatory and quick-acting medications if the wheezing is related to a long-term illness, such as COPD or asthma.

Home remedies may help improve wheezing in some people. For example, keeping your home warm and humid can open up your airways and help you breathe more easily. Sitting in a warm, steamy bathroom can sometimes help. Dry, cold climates can worsen wheezing, especially when exercising outdoors. Complementary medicines may also help control your wheezing. Some herbs and supplements may improve wheezing. It’s important that you discuss any alternative medicines with your doctor before starting them.
