Vocal cord nodules are mainly caused by improper speaking, excessive speaking, emotional excitement, and shouting. The most common symptom of vocal cord nodules is a hoarse voice. This condition is often seen in people who speak a lot, such as teachers, salespeople, and singers. These include individuals who tend to shout, are impatient, and speak improperly. Such cases are commonly seen in clinics, especially among children. For example, children who shout and speak carelessly at school during the semester may develop vocal cord nodules with hoarseness as a symptom. Additionally, emotionally excitable and impatient people can develop nodules. Some grandparents, who often yell at their children at home, also tend to develop vocal cord nodules. In summary, those who speak too much, shout, mispronounce sounds, or are emotionally excitable are at risk of developing vocal cord nodules.
