Mucus also blocks the ducts of the pancreas, preventing enzymes from reaching the intestines to digest food. While there is no cure for the disease, people with CF can live a relatively normal life by undergoing rigorous daily physiotherapy programs, by promptly treating any lung problems, and by taking artificial enzymes with every meal and snack. CF usually develops in infancy or early childhood, and is sometimes confused with other children's diseases. Consult your doctor if you have any concerns. Protect your voice Many a good, natural voice is harmed by vocal abuse.
Some people unknowingly abuse their voices simply by the way they speak or sing.
Others harm their voices by shouting too often, speaking in an unnatural pitch, smoking or indulging in excessive amounts of alcohol and spicy foods. The voice can also be affected by stress. When you're stressed you may subconsciously hold your breath while speaking and stiffen the muscles in your larynx that control the vocal cords. In rare cases, the symptoms mentioned above could signal a more serious problem such as ulcers on the vocal cords, thyroid problems or cancer. If hoarseness doesn't go away after two weeks, or if it is very painful, see your doctor.
