Voice hoarseness and loss of voice – when will it go away on its own, and when should I go to ENT?

In most cases, a hoarse or lost voice is due to a viral infection or vocal strain and recovers within a few weeks. However, if the voice changes are long-lasting, they should not be ignored. The manager of our clinic, dr. med. Rudolfs Janis Viksne explains the most common causes, risk signs and situations when you must visit an ENT specialist.

When we are used to speaking freely on a daily basis, hoarseness or even complete loss of voice can be very troublesome. The first question is usually simple – is it temporary and will go away on its own, or does it still need a doctor's help? As a doctor, I see on a daily basis that patients tend to either get overly worried about a normal hoarseness caused by a virus, or – on the contrary – ignore signals that require action for months. It is important to understand when a home regimen is sufficient and when an examination of the larynx and vocal cords is necessary.

How is the voice formed and what is hoarseness?

The voice is formed when air from the lungs flows through the larynx and causes the vocal cords to vibrate. Medically, hoarseness is called dysphonia – it is any change in voice timbre, volume or tone. If the vocal cords are inflamed, swollen, irritated or overloaded, their vibration changes – the voice becomes rougher, quieter, "tired" or may disappear altogether.

The most common causes of hoarseness

Changes in the voice are most often caused by:

acute viral inflammation (laryngitis) during a cold;

voice overload (prolonged talking, singing, working in a noisy environment);

acid reflux (especially if there is heartburn, a bitter taste in the mouth or hoarseness first thing in the morning);

smoking and other external irritants;

dry indoor air and insufficient fluid intake;

structural changes – vocal cord nodules, polyps or chronic inflammation that requires in-depth investigation.

What is voice loss?

Unlike hoarseness, loss of voice (aphonia) is a condition where a person can only speak in a whisper or the voice disappears completely. It most often occurs due to acute inflammation of the larynx or severe swelling of the vocal cords. Most voice recovers within 5-10 days if a conservative regimen is followed and the underlying cause is treated. However, it should be remembered that if the voice disappears suddenly, without signs of a cold or immediately after a heavy vocal load, this may indicate a more serious damage to the vocal cords, so timely consultation of a specialist is recommended.

What can be done at home if there are no "red flags"?

If the hoarseness is due to a cold or congestion and its duration does not exceed 1-2 weeks, you can usually start with a gentle regimen:

Saving the voice. Speak less and more calmly. It is important to remember that whispering is not a rest for the voice – it strains the vocal cords even more than normal speaking.

Liquid. Drink enough water – the vocal cords need moisture "from the inside".

Humid air. An air humidifier in the room can make you feel better. In addition, you can use oil- or water-based throat sprays, as well as dragees available in pharmacies, which help keep the mucous membrane moist and reduce irritation.

Avoidance of irritants. Smoking, alcohol, very hot or spicy foods, and alcohol-based throat sprays can further dry out and irritate the larynx.

Refusal to crackle. Avoid forcefully clearing your throat. Crackling mechanically irritates the larynx and can prolong the symptoms – it is better to drink a sip of water instead.

When should you definitely go to the doctor?

A hoarse voice may be a signal that the larynx and vocal cords need to be examined. It is recommended not to postpone the ENT consultation if:

hoarseness lasts more than 3 weeks, even if there are no other complaints or pain;

there is no improvement – despite a sparing regimen, the voice does not change or worsens;

the voice becomes weaker and weaker or there is a feeling that the sentence cannot be finished;

there is difficulty or pain in swallowing, as well as pain when touching the larynx from the outside;

there is a persistent feeling of a "lump" in the throat that does not go away;

there is a long history of smoking – voice changes in this group should always be evaluated very carefully;

additional symptoms appear, such as prolonged elevated body temperature for no other clear reason.

You should seek medical help immediately if you experience severe shortness of breath, loud wheezing, inability to swallow saliva, or a sudden, severe increase in throat swelling.

How is the investigation going?

Nowadays, it is not necessary to determine the exact cause by symptoms alone. The ENT specialist evaluates the larynx with fibrolaryngoscopy – using a thin optical instrument – or with rigid endoscopy – using a high-resolution camera that is inserted into the throat. The examination is short and usually well tolerated. Depending on the situation, stroboscopy may also be recommended, which allows for a detailed assessment of vocal cord vibration in slow motion.

Direct visual inspection allows you to determine whether it is a simple inflammation, changes caused by overload or a condition that requires more targeted treatment or even surgical correction.

In most cases, hoarseness is not dangerous and goes away on its own. However, the 3-week mark is the moment when the "let's wait" tactic should be replaced by a visit to a specialist. Early and accurate diagnosis allows any situation to be dealt with more efficiently and more gently.
