6. Rheumatoid Arthritis
Rheumatoid arthritis can cause vocal loss by affecting the small joints of the throat. Patients with rheumatoid arthritis should seek medical attention if they begin to notice hoarseness, as this may be a sign that their airways are becoming restricted. Surgery may be required to prevent the airway from becoming completely closed off.
Smoke, from smoking, secondhand smoke, or exposure to wood-burning stoves can irritate the tissues of the throat and vocal cords. Protect your voice by refraining from smoking and asking others to avoid smoking in your presence. Monitor the air quality in your environment and avoid exposing your throat and lungs to excessive smoke.
4. Thyroid Disorders
Studies show thyroid disease can affect the voice through both physical and hormonal changes. An enlarged thyroid gland can interfere with the movement of the vocal cords. Changes in hormone levels can also affect the strength and quality of the voice. Thyroid surgery can irritate or damage vocal muscles and tissues.
