Nasal congestion

Nasal congestion during pregnancy (Pregnancy rhinitis)

Persistent nasal congestion without other cold symptoms, appearing "out of nowhere" and not resolving, is a very common complaint among expectant mothers. This condition is officially called pregnancy rhinitis. It is not related to viruses or allergies, but is a direct result of hormonal changes in your body.

Why does the nose become congested?

Pregnancy rhinitis is based on two processes:

• Hormonal action. High levels of estrogen and progesterone lead to increased blood flow to the mucous membranes throughout the body. The nasal mucosa is no exception. The influx of blood causes it to swell, which creates the feeling of congestion.
• Increased blood volume. The overall increase in blood volume in the body also contributes to this process.

This condition can occur at any gestational age, but most often appears in the second trimester and can last until delivery. After the baby is born, when the hormonal background normalizes, pregnancy rhinitis usually resolves on its own within 1–2 weeks. In addition to congestion, it may be accompanied by runny nose and sneezing. Although it is not dangerous, persistent nasal congestion can worsen the quality of sleep and cause headaches.
