7. Hormonal Changes: The Endocrine Ebb and Flow
The body’s hormonal fluctuations can turn the tide in the nasal passages as well. Pregnancy, thyroid disorders, and even the use of birth control pills can lead to rhinorrhea. These hormones exert influence over blood flow and tissue response, including those within the nasal passages.
During pregnancy, for instance, increased levels of estrogen can cause the blood vessels in the nose to dilate and the glands to secrete more mucus, leading to what’s often called “pregnancy rhinitis.” This condition usually resolves after childbirth when hormone levels begin to stabilize.
Managing hormone-induced rhinorrhea involves treating the underlying hormonal imbalance. For those unable to take hormone-altering medication, such as pregnant women, using saline sprays and humidifiers can offer some relief. Keeping well-hydrated and avoiding irritants can also help keep the symptoms at bay. (7)
