Sinus infections are characterized by nasal congestion, facial pain, headaches, and difficulty breathing. They can range from mild discomfort to more severe symptoms that interfere with daily life. Understanding how sinus infections happen is key to treating and preventing them. At Southern ENT Specialists, we want to educate our patients about the underlying causes of sinus infections. In this blog, we’ll also cover the best ways to prevent them.
What Are Sinuses?
Here’s what you need to know about the sinuses in order to understand how infections develop:
- The sinuses are a network of hollow, air-filled cavities located in the skull, around the nose and eyes
- They serve as important components of the respiratory system, helping to humidify and filter the air we breathe
- The sinuses also produce mucus, which traps foreign particles like dust, bacteria, and allergens, preventing them from reaching the lungs
- When everything is functioning normally, mucus drains through the nose
- However, when the sinuses become blocked, a sinus infection can develop
How Sinus Infections Develop
Most sinus infections begin with a viral infection, such as the common cold. A cold virus can cause the nasal passages to become inflamed, leading to swelling in the sinus cavities. When this inflammation blocks the sinus openings, mucus builds up inside, leading to pressure and discomfort. This buildup creates the perfect environment for a sinus infection to develop.
Two other causes include the following:
- In some cases, a bacterial infection occurs after the viral infection. When the sinuses remain blocked for a prolonged period, bacteria can multiply in the trapped mucus, turning a simple cold into a more serious sinus infection. This type of sinusitis typically lasts longer than a viral infection and may require antibiotic treatment.
- Though less common, fungal infections can also cause sinusitis, particularly in individuals with weakened immune systems or those with chronic sinus issues. Fungi thrive in moist environments, and blocked sinuses create the perfect conditions for fungal growth.
What Causes Sinus Blockages?
Several factors can contribute to the blockage of the sinuses, leading to infection. Common causes include:
- Allergens like pollen, dust, and pet dander
- Structural issues within the nose, such as a deviated septum or nasal polyps
- Exposure to cigarette smoke, air pollution, or harsh chemicals
- Any infection of the upper respiratory tract, such as a cold or flu
When the sinuses are blocked, the body responds by increasing mucus production in an attempt to flush out the irritants. However, because the sinuses are blocked, the mucus can’t drain properly. As a result, pressure builds within the sinuses, leading to the classic symptoms of sinusitis: pain, congestion, and difficulty breathing.
The buildup of mucus also creates an ideal environment for bacteria and fungi to grow, exacerbating the infection and causing it to linger or worsen.
Preventing Sinus Infections
Prevention is vital when it comes to avoiding sinus infections. Here are some steps you can take to lower your risk:
- Stay Hydrated: Drinking plenty of fluids helps keep mucus thin and allows it to drain more easily.
- Use a Humidifier: Adding moisture to the air can help keep your nasal passages from becoming too dry, especially during the winter months.
- Practice Good Hygiene: Washing your hands regularly can help prevent the spread of germs that cause colds and respiratory infections.
- Avoid Smoking: Smoking irritates the nasal passages and can contribute to chronic sinus problems.
