Many people assume that persistent hoarseness and throat discomfort are simply from a common cold and let them pass. However, recurring hoarseness, throat pain, and a foreign body sensation can be signs of chronic laryngitis rather than a temporary infection. While Donguibogam framed these issues around fire and phlegm, modern medicine explains them through a combination of multiple factors.
One of the most frequent causes is vocal abuse. Shouting at karaoke, using the voice heavily for work, such as teachers, lecturers, and singers, or habitually clearing the throat causes repeated microtrauma to the vocal cords, which can develop into chronic inflammation.
Another major factor is gastroesophageal reflux disease, particularly laryngopharyngeal reflux, where gastric acid flows directly back up into the throat and larynx. Late-night snacks, spicy, salty, or greasy foods, coffee, and carbonated drinks promote excessive gastric acid secretion. Acid vapor travels past the esophagus up to the larynx, causing direct chemical irritation and inflammation in the vocal cords and laryngeal mucosa. This closely mirrors the concept in Donguibogam of fire surging upward into the throat.
Additionally, postnasal drip, where mucus drains down the back of the throat due to allergic rhinitis or chronic sinusitis, is another key culprit that aggravates chronic laryngitis. Sticky mucus constantly irritates the throat mucosa, prompting frequent throat clearing and coughing that strain the vocal cords. This corresponds to the Donguibogam concept of phlegm stagnating in the throat to create a foreign body sensation.
Stress is another critical factor. Chronic stress disrupts autonomic nervous system balance and keeps the body in sustained tension, which increases tightness in the muscles around the neck and shoulders and strains the vocal cords. Stress also stimulates gastric acid production and weakens immunity, worsening inflammatory responses. Hormonal shifts, such as hypothyroidism or the climacteric in women, can lead to dryness and reduced elasticity of the vocal cord mucosa, making hoarseness more likely.
Ultimately, chronic laryngitis often stems from the interaction of three elements: vocal strain, reflux related to dietary habits, and stress. Rather than dismissing it as a simple cold, it is important to pay attention to your body's signals, adjust everyday habits, and seek professional medical evaluation when needed.
