It may come as a surprise to you the variety of medical conditions that can lead to voice problems. The most common causes of hoarseness and vocal difficulties are outlined below. If you become hoarse frequently or notice voice change for an extended period of time, please see your Otolaryngologist (Ear, Nose, and Throat doctor) for an evaluation.
Acute Laryngitis
Acute laryngitis is the most common cause of hoarseness and voice loss that starts suddenly. Most cases of acute laryngitis are caused by a viral infection that leads to swelling of the vocal cords. When the vocal cords swell, they vibrate differently, leading to hoarseness. The best treatment for this condition is to stay well hydrated and to rest or reduce your voice use. Serious injury to the vocal cords can result from strenuous voice use during an episode of acute laryngitis. Since most acute laryngitis is caused by a virus, antibiotics are not effective. Bacterial infections of the larynx are much rarer and often are associated with difficulty breathing. Any problems breathing during an illness warrants emergency evaluation.
Chronic Laryngitis
Chronic laryngitis is a non-specific term and an underlying cause should be identified. Chronic laryngitis can be caused by acid reflux disease, by exposure to irritating substances such as smoke, and by low grade infections such as yeast infections of the vocal cords in people using inhalers for asthma. Chemotherapy patients or others whose immune system is not working well can get these infections too.
Laryngopharyngeal Reflux Disease (LPRD)
Reflux of stomach juice into the throat can cause a variety of symptoms in the esophagus (swallowing tube) as well as in the throat. Hoarseness (chronic or intermittent), swallowing problems, a lump in the throat sensation, or throat pain are common symptoms of stomach acid irritation of the throat. Please be aware that LPRD can occur without any symptoms of frank heartburn and regurgitation that traditionally accompany gastro esophageal reflux disease (GERD).
Voice Misuse and Overuse
Speaking is a physical task that requires coordination of breathing with the use of several muscle groups. It should come as no surprise that, just like in any other physical task, there are efficient and inefficient ways of using your voice. Excessively loud, prolonged, and/or inefficient voice use can lead to vocal difficulties, just like improper lifting can lead to back injuries. Excessive tension in the neck and laryngeal muscles, along with poor breathing technique during speech leads to vocal fatigue, increased vocal effort, and hoarseness. Voice misuse and overuse puts you at risk for developing benign vocal cord lesions (see below) or a vocal cord hemorrhage.
Common situations that are associated with voice misuse:
- Speaking in noisy situations
- Excessive cellular phone use
- Telephone use with the handset cradled to the shoulder
- Using inappropriate pitch (too high or too low) when speaking
- Not using amplification when publicly speaking
Benign Vocal Cord Lesions
Benign non-cancerous growths on the vocal cords are most often caused by voice misuse or overuse, which causes trauma to the vocal cords. These lesions (or “bumps”) on the vocal cord(s) alter vocal cord vibration and lead to hoarseness. The most common vocal cord lesions are nodules, polyps, and cysts. Vocal nodules (also known as nodes or singer’s nodes) are similar to “calluses” of the vocal cords. They occur on both vocal cords opposite each other at the point of maximal wear and tear, and are usually treated with voice therapy to eliminate the vocal trauma that is causing them. Contrary to common myth, vocal nodules are highly treatable and intervention leads to improvement in most cases. Vocal cord polyps and cysts are the other common benign lesions. These are sometimes related to voice misuse or overuse, but can also occur in people who don’t use their voice improperly. These types of problems typically require microsurgical treatment for cure, with voice therapy employed in a combined treatment approach in some cases.
Vocal Cord Hemorrhage
If you experience sudden loss of voice following yelling, shouting, or other strenuous vocal tasks, you may have developed a vocal cord hemorrhage. Vocal cord hemorrhage results when one of the blood vessels on the surface of the vocal cord ruptures and the soft tissues of the vocal cord fill with blood. It is considered a vocal emergency and is treated with absolute voice rest until the hemorrhage resolves. If you lose your voice after strenuous voice use, see your Otolaryngologist as soon as possible.
Vocal Cord Paralysis and Paresis
Hoarseness and other problems can occur related to problems between the nerves and muscles within the voice box or larynx. The most common neurological condition that affects the larynx is paralysis or weakness of one or both vocal cords. Involvement of both vocal cords is rare and is usually manifested by noisy breathing or difficulty getting enough air while breathing or talking. When one vocal cord is paralyzed or weak, voice is usually the problem rather than breathing. One vocal cord can become paralyzed or weakened (paresis) from a viral infection of the throat, after surgery in the neck or chest, from a tumor or growth along the laryngeal nerves, or for unknown reasons. Vocal cord paralysis typically presents with a soft and breathy voice. Many cases of vocal cord paralysis will recover within several months. In some cases however, the paralysis will be permanent and may require active treatment to improve the voice. Treatment choice depends on the nature of the vocal cord paralysis, the degree of vocal impairment, and the patient’s vocal needs. While we are not able to make paralyzed vocal cords move again, there are good treatment options for improving the voice. One option includes surgery for unilateral vocal cord paralysis that repositions the vocal cord to improve contact and vibration of the paralyzed vocal cord with the non-paralyzed vocal cord. There are a variety of surgical techniques used to accomplish this. Voice therapy may be used before or after surgical treatment of the paralyzed vocal cords, or it can also be used as the sole treatment.
Laryngeal Cancer
Throat cancer is a very serious condition requiring immediate medical attention. Chronic hoarseness warrants evaluation by an otolaryngologist to rule out laryngeal cancer. It is important to remember that prompt attention to changes in the voice facilitates early diagnosis. Remember to listen to your voice because it might be telling you something. Laryngeal cancer is highly curable if diagnosed in its early stages.

Difficulty in swallowing (dysphagia) is common among all age groups, especially the elderly. The term dysphagia refers to the feeling of difficulty passing food or liquid from the mouth to the stomach. This may be caused by many factors, most of which are temporary and not threatening. Difficulties in swallowing rarely represent a more serious disease, such as a tumor or a progressive neurological disorder. When the difficulty does not clear up by itself in a short period of time, you should see an otolaryngologist-head and neck surgeon.
How do we swallow?
People normally swallow hundreds of times a day to eat solids, drink liquids, and swallow the normal saliva and mucus that the body produces. The process of swallowing has four related stages:
- The first stage is the oral preparation stage, where food or liquid is manipulated and chewed in preparation for swallowing.
- The second stage is the oral stage, where the tongue propels the food or liquid to the back of the mouth, starting the swallowing response.
- The third stage is the pharyngeal stage which begins as food or liquid is quickly passed through the pharynx, the region of the throat which connects the mouth with the esophagus, then into the esophagus or swallowing tube.
- In the final, esophageal stage, the food or liquid passes through the esophagus into the stomach.
Although the first and second stages have some voluntary control, stages three and four occur involuntarily, without conscious input.
What are the symptoms of swallowing disorders?
Symptoms of swallowing disorders may include:
- Drooling
- A feeling that food or liquid is sticking in the throat
- Discomfort in the throat or chest (when gastro esophageal reflux is present)
- A sensation of a foreign body or “lump” in the throat
- Weight loss and inadequate nutrition due to prolonged or more significant problems with swallowing
- Coughing or choking caused by bits of food, liquid, or saliva not passing easily during swallowing, and being sucked into the lungs
- Voice change
How are swallowing disorders diagnosed?
When dysphagia is persistent and the cause is not apparent, the otolaryngologist-head and neck surgeon will discuss the history of your problem and examine your mouth and throat. This may be done with the aid of mirrors. Sometimes a small tube (flexible laryngoscope) is placed through the nose and the patient is then given food to eat while the scope is in place in the throat. These procedures provide visualization of the back of the tongue, throat, and larynx (voice box). These procedures are called FEES (Fiber optic Endoscopic Evaluation of Swallowing) or FEESST (Flexible Endoscopic Evaluation of Swallowing with Sensory Testing). If necessary, an examination of the esophagus, named TransNasal Esophagoscopy (TNE), may be carried out by the otolaryngologist. If you experience difficulty swallowing, it is important to seek treatment to avoid malnutrition and dehydration.
How are swallowing disorders treated?
Many of these disorders can be treated with medication. Drugs that slow stomach acid production, muscle relaxants, and antacids are a few of the many medicines available. Treatment is tailored to the particular cause of the swallowing disorder.
Gastro esophageal reflux can often be treated by changing eating and living habits in these ways:
- Eat a bland diet with smaller, more frequent meals.
- Eliminate tobacco, alcohol and caffeine.
- Reduce weight and stress.
- Avoid food within three hours of bedtime.
- Elevate the head of the bed at night.
If these don’t help, antacids between meals and at bedtime may provide relief.
Many swallowing disorders may be helped by direct swallowing therapy. A speech pathologist can provide special exercises for coordinating the swallowing muscles or stimulating the nerves that trigger the swallow reflex. Patients may also be taught simple ways to place food in the mouth or position the body and head to help the swallow occur successfully.
Some patients with swallowing disorders have difficulty feeding themselves. An occupational therapist or a speech language pathologist can aid the patient and family in feeding techniques. These techniques make the patient as independent as possible. A dietician or nutritional expert can determine the amount of food or liquid necessary to sustain an individual and whether supplements are necessary.
Once the cause is determined, swallowing disorders may be treated with:
- medication
- swallowing therapy
- surgery
Surgery is used to treat certain problems. If a narrowing exists in the throat or esophagus, the area may need to be stretched or dilated. If a muscle is too tight, it may need to be dilated or released surgically. This procedure is called a myotomy and is performed by an otolaryngologist-head and neck surgeon.
Many diseases contribute to swallowing disorders. If you have a persistent problem swallowing, see an otolaryngologist-head and neck surgeon.
What causes swallowing disorders?
Any interruption in the swallowing process can cause difficulties. Eating slowly and chewing thoroughly can help reduce problems with swallowing. However, difficulties may be due to a range of other causes, including something as simple as poor teeth, ill fitting dentures, or a common cold. One of the most common causes of dysphagia is gastro esophageal reflux. This occurs when stomach acid moves up the esophagus to the pharynx, causing discomfort. Other causes may include: hypertension; diabetes; thyroid disease; stroke; progressive neurologic disorder; the presence of a tracheotomy tube; a paralyzed or unmoving vocal cord; a tumor in the mouth, throat, or esophagus; or surgery in the head, neck, or esophageal areas.
Swallowing difficulty can also be connected to some medications including:
- Nitrates
- Anticholinergic agents found in certain anti-depressants and allergy medications
- Calcium tablets
- Calcium channel blockers
- Aspirin
- Iron tablets
- Vitamin C
- Antipsychotic
- Tetracycline (used to treat acne)
