Elaf: The human voice is subject to change for several reasons, including physiological, pathological and third-party environmental influences or behavioral changes in daily life.
And pathological causes, including those related to organic diseases of the throat or other parts of the body, including those related to mental aspects and the nervous system. Some of these voice changes may be immediate and temporary, while others may become chronic. Some of them are eliminated by topical treatments in the vocal tract, and some of them are eliminated by treating other parts of the body.
The nine reasons:
1- Puberty: The voice of boys and girls changes during puberty as the body undergoes many structural changes that occur under the influence of hormonal changes. Most of the hormones that affect the voice of male and female teenagers are the sex hormones. Testosterone is a male hormone, which begins to increase in boys during puberty, and causes the volume of the voice box to grow in the larynx, and to descend downwards, with widening and thickening of the vocal cords. Estrogen is a female hormone that begins to rise in girls during puberty. It causes a slight increase in the volume of the voice box and a thinning of the vocal cords. They are the ones that cause the voice differences between men and women after puberty.
2- Advanced age: Advanced age affects multiple aspects of the anatomy and function of the vocal cord folds in the larynx. Vocal cord muscle atrophy is very similar to muscle atrophy found elsewhere in the body. The elastic tissues responsible for the vibration of the vocal cords during articulation become weaker in structure, more rigid and less flexible.
3- The Menstrual Cycle: Hormonal changes throughout the menstrual cycle are known to produce unique effects. Research has shown that women’s voices are perceived as more attractive during the “high fertility” phases of the menstrual cycle.
4- Gastric acids: The arrival of gastric acids in the throat and the larynx is a possible cause of irritation and inflammation of the folds of the vocal cords, and therefore of the appearance of hoarseness. Since the structures in this area are more sensitive to stomach acid and digestive enzymes, the presence of small amounts of them in this area can lead to further damage.
5- Thyroid disorders. Diseases of the thyroid gland and disorders of the functioning of the parathyroid glands are the most common endocrine disorders causing voice disorders. Even with mild hypothyroidism, a low voice, hoarseness, and voice fatigue may occur. Hyperthyroidism can also be caused by a voice defect.
6- Laryngitis: According to doctors at Johns Hopkins, “When laryngitis occurs, the vocal cords swell, like any swelling of the inflamed tissue, which makes the voice hoarse, or the voice may disappear and one may not be able to speak at all.” Acute laryngitis occurs suddenly, often due to the presence of a virus in the upper respiratory tract, such as a cold.Traumatic damage to the folds of the vocal cords can also occur when the voice is used extensively during an episode. acute laryngitis.
7- “Vocal abuse”: One of the main causes of voice changes is not using the ability to vocalize softly and correctly. For example, speaking in a high, loud voice in noisy situations, overusing without resting the throat, using the phone with the phone resting on the shoulder, and using an inappropriate tone (too high or too low) when speaking.
8- Neurological diseases and disorders: “With Alzheimer’s disease and Parkinson’s disease, one of the first noticeable changes is the voice,” explains Dr. Anis Ramo, MD, laryngologist at Weill Cornell Medical College in New York. “Parkinson’s disease can soften the voice, or make it monotonous, whereas Parkinson’s disease can dull the voice or make it monotonous.” Alzheimer’s disease can alter the content of speech, leading to increased (umm) and a preference for pronouns over nouns.
Complete paralysis or partial paralysis of the vocal cords can cause hoarseness or a high pitched tone of voice. Either as a result of a viral infection that affects the nerves of the vocal cords, or as a result of nerve damage during surgery, or as a result of a stroke or cancer.
9- Masses and Tumors: The way the vocal cords are used to produce sound, mechanical stresses, excessive, chronic and repetitive mechanical stresses of the vocal cords (talking long, speaking loudly, shouting), especially in women, can be the cause of the development of a nodule (a hard, benign, benign, raised mass of variable size), or cysts (a small, closed sac, with a membrane and borders, which differs from adjacent tissue), or d ‘a polyp (a tumor due to abnormal growth of mucous membrane tissue of varying sizes), in the vocal cords. Each of them has different causes and mechanisms in appearance and method of treatment.
