Respiratory system

This category groups symptoms related to breathing and the airway, including changes affecting the nose such as nasal congestion. These symptoms can arise from many different situations, ranging from minor and temporary issues to conditions that benefit from professional evaluation, and they often overlap with each other.

The information on this page and in the linked articles is general in nature. It is not a diagnostic tool and does not replace professional medical advice. A single symptom, such as nasal congestion, does not by itself identify any particular disease; a clinician will assess the full picture, including history and examination, before reaching any conclusion.

Symptoms in this category

• Nasal congestion: a sensation of blocked or stuffy nose that can affect one or both sides and may vary throughout the day

How to describe these symptoms in a consultation

• Note when the congestion started and whether it has been constant or comes and goes
• Mention whether one or both nostrils are affected
• Describe any accompanying signs, such as discharge, facial pressure, changes in smell, or fever
• Mention possible triggers, such as exposure to irritants, allergens, or recent respiratory infections
• Note whether anything seems to make it better or worse, including position or time of day

When to seek care

General criteria for consulting include congestion that persists beyond a couple of weeks, that recurs frequently, or that is affecting sleep, daily activities, or that appears together with other symptoms causing concern. A clinician can help clarify what might be contributing to it and whether further assessment is needed.

In some situations, care should be sought without delay. If any of the following occur, call your local emergency number or attend an emergency department rather than waiting:

• Sudden difficulty breathing or shortness of breath
• Swelling of the face, lips, or throat
• High fever with severe facial pain or confusion
• Nasal congestion following a head injury, especially with clear fluid drainage
• Any sudden, severe symptom that feels different from previous episodes
