Anyone can develop a sinus infection. However, sinusitis is more likely to affect persons with nasal allergies, nasal polyps, asthma, or atypical nose structures. Additionally, smoking can increase the frequency of sinus infections. 

Here are some reasons why you may have sinusitis and, more importantly, when it is crucial to see a doctor.

Reasons Why You May Have Sinusitis

1. Nasal Polyps
   If you have nasal polyps in your sinuses or nose, you may have smell loss and difficult breathing through your nose. If the polyps are large, they may obstruct your nose, causing mouth breathing and persistent sinus infections.
   
   
2. Viruses and Bacteria
   The majority of adult cases of sinusitis are brought on by viral infections. Usually, when we talk about viruses, we're talking about upper respiratory tract illnesses like the flu or the common cold. Sinus infections caused by bacteria can last longer. If the infection lasts for over 3 months, we call it chronic sinusitis.
   
   
3. Deviated Septum
   Your septum, which is formed of cartilage and bone, separates your nostrils. Your septum would evenly split your nasal passages in an ideal case. Most people do, however, have some septal deviation, which can constrict or block nasal passages and aggravate sinusitis symptoms.
   
   
4. Other Medical Conditions
   Nasal blockage can result from the side effects of illnesses such as cystic fibrosis, HIV, and other immune system-related ailments. Also, in the case of allergic rhinitis, allergens irritate the sinuses and nasal passages, which triggers an inflammatory reaction. Seasonal sinusitis is a common symptom of allergic rhinitis as well.
   
   
5. Small Structural Sinuses
   Due to their structurally limited sinus cavities, some people get chronic sinusitis. If your sinuses openings are narrow, there may not be many areas for even a small amount of swelling, which can cause pain and discomfort.
   
   
6. Other Potential Reasons
   Other potential reasons in different age groups for sinusitis are listed below:

• An immune system that is weak or compromised by diseases or drugs can also lead to sinusitis in most cases.
• Infants and young children may be more susceptible to sinusitis if they spend time in daycares.
• Adult smokers are more likely to have sinus infections. If you smoke, you should try to give it up. Smoking is hazardous to both the smoker and others around them.

When You Should Visit a Health Professional

You should make an appointment with an ear, nose, and throat doctor (otolaryngologist) if you've often experienced sinusitis and the ailment is unresponsive to medication, or if you experience sinusitis symptoms for several months.

If you have any of the following indications of a dangerous infection, consult a doctor right away:

• Terrible headache
• Forehead swelling
• Fever
• Swelling or redness around your eyes
• Stiff neck
• Significant vision changes, such as double vision
