      After getting better from a cold, many people will fall into the dilemma of "phlegm clinging to people" - there always seems to be sticky foreign matter in the throat, they can't cough and swallow, they have a thick nasal sound when speaking, and coughing up phlegm at night can also affect their sleep. This condition is mostly caused by damage to the respiratory mucosa during a cold, resulting in increased secretions and poor drainage.

    What should I do if I have phlegm all the time after catching a cold?

      1. Syndrome differentiation and dietary therapy to help eliminate phlegm

      If the phlegm is white and thin, accompanied by fear of cold and stuffy nose, it means that the lingering wind-cold evil has not dissipated. You can make ginger and radish soup. Ginger can dispel cold and radish can smoothen the air, which can help warm up cold phlegm.; If the phlegm is yellow and thick and the throat is slightly sore, it is due to wind-heat residue. Take 5 grams of Sichuan clams and 1 Sydney pear (removed and cut into pieces), add a small amount of rock sugar and steam for 15 minutes before eating. Sichuan clams moisten the lungs and relieve coughs, while Sydney clears away heat and resolves phlegm. It is suitable for people with dry phlegm.

      2. Replenish enough water to dilute phlegm

      Drink 1500-2000 ml of warm water every day, or soak in light honey water or tangerine peel water. The water can dilute the sticky sputum and reduce the difficulty of coughing up phlegm. Avoid drinking ice water and strong tea. The former may irritate the respiratory tract, while the theophylline in the latter may aggravate dryness of the mucous membranes and hinder phlegm discharge.

      3. Pat your back correctly to promote discharge

      When you are unable to cough up phlegm, you can ask family members to help pat you on the back. The person who pats the back should put their fingers together and make the palm slightly concave to form a hollow palm. Starting from the lower side of the back, pat gently from outside to inside and from bottom to top, for 10-15 minutes each time. It is best to do it 1 hour after a meal or half an hour before a meal. Vibration can help loosen phlegm and fall off.

    What abnormalities should you be alert to when you have phlegm after a cold?

      1. Abnormal color and smell of phlegm

      If the sputum is yellow-green and thick, accompanied by an obvious odor, or the sputum is stained with blood, it may be a bacterial infection that causes bronchitis or pneumonia. You need to see a doctor in time to check the blood routine and take antibiotics as directed by the doctor if necessary.

      2. Coughing up phlegm that lasts for more than two weeks

      Sputum usually gradually decreases within a week after a common cold. If it persists for more than 14 days without improvement, it may develop into chronic pharyngitis or allergic cough. Allergens or respiratory structural problems need to be investigated to avoid delays in treatment.

      3. Accompanied by general discomfort

      If you have fever (body temperature over 38.5°C), chest pain, or difficulty breathing when coughing sputum, it may be a sign of lung infection. Do not self-medicate. See a doctor immediately for a chest X-ray examination to identify the cause and then provide targeted treatment.

      Coughing up phlegm after a cold is a self-healing process of the respiratory tract, and most people can gradually recover through reasonable conditioning. If the above abnormalities occur, you must pay attention and seek medical treatment promptly to prevent small problems from developing into major hidden dangers and protect respiratory health.
