Pregnancy and phlegm sensation in the throat?


Hello, doctor.
I am in the early stages of pregnancy and had a severe cold that lasted for over two months (with cough and yellow phlegm).
Now I am 18 weeks pregnant, and while my cold has improved, I still feel like I have phlegm stuck in my throat every day.
I find myself clearing my throat frequently, but I can't seem to cough up the phlegm.
It feels like there is always some phlegm in my throat, and drinking water doesn't help.
Could this be related to my initial cold? Does it mean my cold hasn't fully resolved, or could it be a form of allergy? Thank you.

Lovely, 30~39 year old female. Ask Date: 2013/12/12

More Info


Persistent phlegm in the throat during pregnancy can be quite uncomfortable and concerning for many women. Given your history of a severe cold in the early stages of your pregnancy, it is possible that the lingering sensation of phlegm is related to that initial illness. However, there are several factors to consider that could contribute to this sensation, and it is essential to explore potential causes and solutions.


Possible Causes:
1. Post-Nasal Drip: After a cold, it is common for mucus to continue to drain from the sinuses into the throat, leading to a sensation of phlegm. This can occur even after other cold symptoms have resolved. The body may still be producing mucus as a response to inflammation or irritation in the airways.

2. Allergies: Pregnancy can heighten sensitivity to allergens. If you have developed new allergies or if existing allergies have worsened, this could lead to increased mucus production and a feeling of phlegm in the throat.

3. Gastroesophageal Reflux Disease (GERD): Hormonal changes during pregnancy can relax the lower esophageal sphincter, leading to acid reflux. This can cause irritation in the throat and a sensation of mucus buildup.

4. Hormonal Changes: Pregnancy hormones, particularly progesterone, can affect mucus production and the viscosity of secretions in the respiratory tract, potentially leading to a feeling of congestion or phlegm.

5. Infections: While your cold may have resolved, other infections such as sinusitis or bronchitis could still be present, contributing to ongoing mucus production.


Solutions and Recommendations:
1. Stay Hydrated: Drinking plenty of fluids can help thin mucus, making it easier to clear from your throat. Warm fluids, such as herbal teas or broths, can be particularly soothing.

2. Steam Inhalation: Inhaling steam from a bowl of hot water or taking a warm shower can help loosen mucus and relieve throat irritation.

3. Saline Nasal Spray: Using a saline nasal spray can help moisten nasal passages and reduce post-nasal drip, which may alleviate the sensation of phlegm in your throat.

4. Humidifier: Keeping a humidifier in your bedroom can add moisture to the air, which may help reduce throat irritation and mucus production.

5. Avoid Irritants: Stay away from smoke, strong odors, and other irritants that can exacerbate throat discomfort.

6. Consult Your Healthcare Provider: If the sensation persists or worsens, it is essential to consult your obstetrician or a healthcare provider. They may recommend further evaluation to rule out any underlying conditions, such as allergies or infections, and can provide appropriate treatments that are safe during pregnancy.

7. Monitor for Other Symptoms: Keep an eye on any additional symptoms, such as fever, persistent cough, or changes in mucus color, which could indicate an infection requiring medical attention.

In conclusion, while the sensation of persistent phlegm in your throat may be related to your previous cold, it is essential to consider other potential causes, including allergies and hormonal changes. Staying hydrated, using steam inhalation, and consulting with your healthcare provider can help manage this discomfort effectively. Remember, your healthcare provider is your best resource for personalized advice during your pregnancy.
