What causes morning phlegm and dry retching?

Environmental pollution, declining air quality, and high levels of life stress can gradually weaken the body’s immune system. Neglecting dietary habits may lead to discomfort such as coughing and phlegm production. Some individuals constantly feel phlegm in their throat, resulting in dry retching—especially noticeable upon waking in the morning. So, what causes phlegm-related dry retching in the morning?

What Causes Phlegm-Related Dry Retching in the Morning?

Phlegm-related dry retching upon waking may indicate pharyngitis, which is categorized as either acute or chronic. Acute pharyngitis is often initially caused by common cold viruses; treatment may include oral liquid medications, as prescribed by a physician. In cases of advanced pharyngitis—or when phlegm appears purulent—antibiotic therapy is typically required. The presence of lymphoid follicle hyperplasia in the throat suggests chronic pharyngitis. Patients are generally advised to consume foods rich in vitamin C to bolster immunity.

Patients are advised—under medical guidance—to prepare herbal infusions using ingredients such as citrus fruit, lily bulb (Bulbus Lilii), scrophularia root (Radix Scrophulariae), ophiopogon tuber (Radix Ophiopogonis), or fat sea date (Semen Sterculiae Lychnophorae) in water. These preparations can effectively reduce morning phlegm accumulation and the sensation of a foreign body in the throat. Honey may be added before consumption to enhance moisturizing and expectorant effects. Additionally, patients should engage in moderate physical activity, quit smoking and alcohol, and maintain a light, bland diet. Symptoms typically show marked improvement within approximately 1–2 months.

Patients should maintain a light, bland diet and avoid spicy or irritating foods in the evening. Smoking and alcohol consumption must also be avoided. We hope this information proves helpful.
