Coughing and yellow nasal discharge during the second trimester of pregnancy may result from hormonal changes causing respiratory sensitivity, cold exposure, upper respiratory tract infection, acute sinusitis, or bacterial pharyngitis. Symptoms can be improved through warmth protection, hydration, and medication. If symptoms worsen or are accompanied by fever or chest pain, prompt medical attention is necessary.

1. Hormonal changes leading to respiratory sensitivity: Fluctuations in hormone levels during pregnancy can cause congestion and swelling of the respiratory mucosa, making it more susceptible to external irritants, resulting in coughing. Increased mucus secretion may lead to yellow nasal discharge. It is recommended to maintain indoor ventilation, avoid exposure to dust and strong odors, and wear a mask outdoors to reduce irritation.

2. Cold exposure: Immunity is slightly reduced during pregnancy, and cold exposure can irritate the respiratory mucosa, leading to coughing, increased nasal secretions that turn yellow, and possibly mild nasal congestion. It is advised to dress warmly, drink warm lemon water, and ensure adequate rest to boost immunity.

3. Upper respiratory tract infection: Viral or bacterial infection of the upper respiratory tract causes inflammation that irritates the throat and nasal passages, leading to coughing and yellow nasal discharge, possibly accompanied by sore throat. Under medical guidance, medications such as Pudilan Xiaoyan Oral Liquid, Ganmao Qingre Granules, or Amoxicillin Capsules may be used to relieve symptoms.

4. Acute sinusitis: Inflammation spreads from the nasal cavity to the sinuses, causing the sinus mucosa to become inflamed and produce pus, resulting in yellow nasal discharge, nasal congestion, and cough due to inflammatory irritation. Under medical supervision, patients may use saline nasal sprays, Cefaclor capsules, or Tongqiao Biyan Tablets to alleviate discomfort.

5. Bacterial pharyngitis: Bacterial infection causes throat inflammation with redness, swelling, and pain, triggering coughing. The inflammation may spread to the nasal cavity, causing yellow nasal discharge. As directed by a physician, medications such as Cefuroxime Axetil Tablets, Chuanbei Pipa Syrup, or Compound Chlorhexidine Mouthwash may be used to improve symptoms.

Maintain regular sleep patterns and sufficient rest, follow a light and easily digestible diet rich in fruits and vegetables, drink warm water in moderation to soothe the respiratory tract, avoid spicy and greasy foods, keep indoor humidity at comfortable levels, and engage in gentle walking to strengthen the body and support recovery.

Is a low body temperature in the morning a sign of a cold?

If low body temperature in the morning is accompanied by typical cold symptoms such as nasal congestion, runny nose, sore throat, and mild cough, it may indicate the onset of a cold. In the early stage of a cold, the body's immune system activates, causing some individuals to experience temporary fluctuations in body temperature and mild chills, which may manifest as lower morning temperatures. This may later progress to fever or worsening symptoms; therefore, assessment should be based on the overall clinical presentation.

Can people with a cold take Cordyceps militaris?

If after a cold you only have mild nasal congestion and runny nose, without serious discomfort such as fever or sore throat, and if you have previously consumed cordyceps militaris (Jinchanhua) without allergic reactions or gastrointestinal discomfort, consuming a small amount is generally safe. The nutrients in cordyceps militaris may help support physical strength. At this time, when your body's burden is light, moderate consumption usually does not worsen cold symptoms or cause adverse reactions.
