Short answer

Otolaryngology(이비인후과) is generally the first department to see for nasal congestion, as it specializes in conditions affecting the nose, sinuses, and upper airways. If the congestion appears related to allergies, an Allergy & Clinical Immunology(알레르기내과) or Internal Medicine(내과) consultation may follow. In children, a Pediatrics(소아청소과) clinic is typically the starting point before any specialist referral.

Which department

  1. 1Otolaryngology(이비인후과)
    This specialty focuses on the nose, sinuses, throat, and ears, making it the most direct match for nasal congestion of nearly any cause — structural, infectious, or inflammatory. — First / second line: For most adults, visiting an Otolaryngology clinic(의원-level) first is the common approach in Korea; a referral to a hospital(병원)-level department is generally arranged if imaging or surgical evaluation is needed.
  2. 2Allergy & Clinical Immunology(알레르기내과)
    When nasal congestion is suspected to be driven by allergic responses — such as seasonal or perennial rhinitis — this department evaluates the immune-related background of the symptom. — First / second line: A referral from a primary clinic is generally needed to see this specialty at a hospital level; it is not usually the very first stop unless the allergic cause is already well established.
  3. 3Internal Medicine(내과)
    General internal medicine practitioners can assess nasal congestion in the context of systemic conditions and provide an initial evaluation when an Otolaryngology clinic is not immediately accessible. — First / second line: An internal medicine clinic(의원) can serve as a convenient first contact, and the physician may then issue a referral letter(진료의뢰서) to Otolaryngology if a more focused evaluation is warranted.
  4. 4Pediatrics(소아청소과)
    For infants and young children, a pediatrician is generally the appropriate first contact for nasal congestion because the clinical picture and management considerations differ significantly from adults. — First / second line: Parents typically start at a pediatric clinic(의원); referral to a pediatric Otolaryngology(소아이비인후과) specialist at a hospital level is arranged when the condition persists or a structural cause is suspected.

Go to the ER / call 119 if

If any of the following applies, do not choose a department — go to an emergency room or call 119 (Korea's emergency number).

  • Nasal congestion is accompanied by sudden severe headache that is unlike any headache experienced before
  • High fever combined with stiff neck and sensitivity to light develops alongside the congestion
  • Vision changes, double vision, or swelling around the eyes appears
  • One-sided facial drooping, sudden confusion, or difficulty speaking occurs at the same time
  • Breathing becomes so obstructed that normal breathing at rest is impossible

Before your visit

  • Note exactly when the congestion started and whether it appeared suddenly or gradually over days or weeks.
  • Observe whether one or both sides of the nose are blocked, and whether the blockage is constant or comes and goes.
  • Keep track of any accompanying symptoms such as facial pressure, headache, fever, changes in smell, or ear fullness.
  • List all medications, supplements, and nasal sprays you are currently using, including over-the-counter products, since some can affect nasal lining.
  • Bring any previous allergy test results, imaging reports, or records from prior ENT visits if you have them.
  • Think about potential triggers — season changes, pets, dust, or specific environments — that seem to worsen the symptom.

General principles

Nasal congestion occurs when the mucous membranes lining the nasal passages become swollen or when structural issues restrict airflow; because the nose connects directly to the sinuses, ears, and throat, Otolaryngology is positioned to evaluate all of these related areas in a single visit.

In the Korean healthcare system, it is generally common to visit a primary-level clinic(의원) first; if the clinician determines that further workup — such as endoscopic examination or imaging — is needed, a referral to a secondary or tertiary hospital(병원·종합병원) follows, often with a referral letter that helps maintain health insurance coverage.

Diagnostic approaches in Otolaryngology typically involve examining the nasal cavity and may extend to assessing the sinuses or neighboring structures; the specific tests or examinations applied depend on the findings during the consultation, and the decision rests entirely with the attending physician.

When an allergic background is suspected, an allergy workup may be coordinated between Otolaryngology and an allergy specialist, illustrating how nasal congestion can sometimes require a multi-department approach rather than a single-visit resolution.

FAQ

Should I go to a small clinic(의원) or a larger hospital(병원) for nasal congestion?

For a first visit, a primary Otolaryngology clinic(이비인후과 의원) is generally the appropriate starting point in Korea. Larger hospitals are typically accessed after a referral when complex evaluation is needed, and visiting a large hospital directly without a referral may result in a higher out-of-pocket cost under the national health insurance system.

Could my nasal congestion be an allergy rather than an infection, and does that change which department I visit?

Both allergic rhinitis and infectious causes can produce similar congestion, and distinguishing between them generally requires a clinical evaluation rather than self-assessment. An Otolaryngology specialist can assess both possibilities, and if a detailed allergy workup is warranted, a referral to Allergy & Clinical Immunology may be arranged afterward.

What kinds of examinations are generally done for nasal congestion at an ENT clinic?

A physician may look inside the nasal passages using a light or a small scope to observe the mucous membranes and nasal structures; additional assessments such as imaging or allergy testing are ordered only when the initial examination suggests they are needed. The specific steps depend entirely on the individual findings and are decided by the consulting doctor.

Is the process different for a child with nasal congestion compared to an adult?

Children are generally seen by a Pediatrics(소아청소과) physician first, who can evaluate the congestion in the context of the child's overall health and development. If a structural or persistent issue is identified, the pediatrician typically refers the child to a specialist in pediatric Otolaryngology rather than an adult ENT clinic.
