How Deviated Septum Affects Your Breathing and What You Can Do About It

A deviated septum is more than just a medical term—it’s a real issue that can significantly affect your quality of life, especially your ability to breathe comfortably. Many people don’t even realize they have a deviated septum until the symptoms begin interfering with everyday activities. If you’ve been experiencing breathing difficulties, frequent nasal congestion, or persistent sinus infections, a deviated septum might be to blame.

This blog will explore how a deviated septum impacts your breathing, the signs you should watch for, and what treatment options are available. We’ll also discuss your options for obtaining a doctor’s note for work, FMLA certification, or a medical certificate for leave—particularly if your condition requires time off or medical procedures.

Understanding the Basics: What Is a Deviated Septum?

The septum is the thin wall of bone and cartilage that separates your left and right nasal passages. Ideally, it’s centered, allowing air to flow evenly through both sides. A deviated septum occurs when this wall is displaced to one side, either from birth or due to trauma like a sports injury or accident.

In some people, the deviation is mild and causes no noticeable symptoms. In others, the misalignment can block one side of the nose and reduce airflow, making breathing difficult.

How a Deviated Septum Affects Breathing

When the nasal septum is not aligned properly, it creates an imbalance in airflow. This can lead to several issues:

  1. Nasal Obstruction

The most immediate and noticeable symptom is difficulty breathing through one or both nostrils. You might find that one side of your nose feels perpetually clogged, especially when lying down.

  1. Snoring and Sleep Disruption

A blocked nasal passage can contribute to loud snoring or even sleep apnea. Poor sleep quality affects mental focus, energy levels, and overall health, often leading individuals to seek medical attention or even request a doctor’s note for work.

  1. Chronic Sinus Infections

When airflow is disrupted, mucus doesn’t drain properly. This can cause recurring sinus infections, facial pain, and headaches.

  1. Reduced Oxygen Intake

Some people experience fatigue and light-headedness due to the reduced intake of oxygen. While subtle at first, these symptoms can affect your productivity and ability to perform daily tasks.

When Should You Seek Medical Help?

You should consult a healthcare provider if you notice:

  • Persistent nasal congestion
  • Frequent sinus infections
  • Breathing difficulties, especially during exercise
  • Trouble sleeping due to nasal blockage
  • Recurrent nosebleeds

If these symptoms start affecting your performance at work or daily life, your doctor may recommend treatment and could provide a medical certificate for leave or assist with FMLA certification if extended care is necessary.

Diagnosis and Treatment Options

A deviated septum is typically diagnosed through a physical examination using a nasal speculum and light. In some cases, imaging tests may be used to evaluate the severity.

Non-Surgical Treatments

Nasal Corticosteroids

Nasal corticosteroids are anti-inflammatory medications sprayed directly into the nostrils to reduce swelling in the nasal passages. They are often the first line of treatment for conditions like allergic rhinitis, nasal polyps, and chronic sinusitis. By decreasing inflammation, they help open up the airways, reduce mucus production, and alleviate symptoms such as congestion, sneezing, and runny nose.

Decongestants

Decongestants provide temporary relief from nasal congestion by shrinking swollen blood vessels in the nasal membranes. Available as oral tablets or nasal sprays, they help clear blocked nasal passages, making breathing easier. Common decongestants include pseudoephedrine (oral) and oxymetazoline (nasal spray). However, nasal decongestant sprays should not be used for more than three consecutive days, as overuse can lead to rebound congestion, where symptoms return even more intensely.

Antihistamines

Antihistamines work by blocking the effects of histamine, a chemical released by the immune system during allergic reactions. This helps reduce symptoms such as sneezing, itching, runny nose, and watery eyes. There are two main types: first-generation antihistamines, which may cause drowsiness (like diphenhydramine), and second-generation options that are less sedating (like loratadine, cetirizine, and fexofenadine).

Nasal Strips or Dilators

Nasal strips and internal nasal dilators are non-medicated devices designed to improve airflow by mechanically opening the nasal passages. Worn externally across the bridge of the nose, nasal strips use adhesive tension to gently lift and open the nostrils, reducing resistance during breathing. Internal dilators, on the other hand, sit inside the nostrils to create a similar widening effect from within. Internal dilators, placed inside the nostrils, create a similar effect from within.

These treatments are best for managing symptoms but won’t correct the deviation.

Surgical Intervention: Septoplasty

If your symptoms become severe, your doctor may recommend septoplasty—a surgical procedure that straightens the septum. Most patients undergo this surgery under general anesthesia and take about 1 to 2 weeks to recover.

If you need surgery, your healthcare provider can provide a doctor’s note to support your time off from work. You may also qualify for FMLA certification, especially if the condition affects your job performance or requires extended recovery time.

Getting Time Off: Your Options for Documentation

In cases where your deviated septum affects your ability to work, sleep, or perform basic functions, proper documentation is crucial. Here’s how to navigate your options:

Doctor’s Note for Work

Your healthcare provider can write a detailed note explaining your condition and the medical necessity of time off. This note typically includes:

  • Diagnosis
  • Recommended treatment
  • Duration of absence

FMLA Certification

If your condition is chronic or requires surgery, you may qualify for the Family and Medical Leave Act (FMLA). Your employer may require a formal certification from your doctor, detailing:

  • The nature of your medical condition
  • The expected duration of leave
  • Any work restrictions during recovery

Medical Certificate for Leave

In some cases, particularly in schools or public service roles, you may be asked to submit a medical certificate for leave. This official document confirms your medical issue and need for time off.

Lifestyle Adjustments to Improve Breathing

While waiting for medical treatment or managing a mild deviation, you can make simple lifestyle changes to ease breathing problems:

  • Use a humidifier: Moist air can reduce nasal drynessand congestion
  • Stay hydrated: Helps thin mucus and promote drainage
  • Elevate your head while sleeping: Prevents nasal blockage
  • Avoid allergens: Reduces inflammation and irritation in the nasal passages
  • Practice nasal irrigation: Saline rinses can clear nasal passages effectively

A deviated septum can seem like a minor issue, but for many, it severely affects breathing, sleep, and overall comfort. Left untreated, it can lead to chronic sinus issues and lower quality of life. Fortunately, both medical and surgical options are available, and you don’t have to let the symptoms interfere with your work or daily routine.
