Thyroid Disease: Symptoms and When to See a Doctor

The thyroid is a small, butterfly-shaped organ located at the front of the neck, just below the Adam's apple and in front of the trachea (the airway). Although it weighs only a few dozen grams, the hormones it produces influence heart rate, body temperature, digestion, weight, sleep, mood and day-to-day energy. For this reason, when the thyroid is not working properly, the symptoms are often scattered and difficult to attribute immediately to a single cause.

In otorhinolaryngology (the speciality dealing with the ear, nose and throat), the thyroid is of particular interest because it lies precisely in the neck region. An enlarged gland or nodules can cause a feeling of pressure in the throat, hoarseness, difficulty swallowing or a visible swelling of the neck — complaints that usually bring patients to the ENT doctor.

What the thyroid gland does

The thyroid produces two main hormones, known as T3 and T4, which regulate metabolism — the way the body uses energy. Their production is controlled by the pituitary gland, a small gland in the brain that releases the hormone TSH. This balance is delicate: if it is disturbed, the consequences are felt in several body systems at the same time.

To function normally, the thyroid needs iodine, an element we obtain through food and iodised salt. A persistent lack of iodine has historically been one of the leading causes of thyroid enlargement in certain regions.

The main types of thyroid disease

Hypothyroidism — an underactive thyroid

This occurs when the gland produces fewer hormones than the body needs. Metabolism slows down and the symptoms develop gradually, often over months. The most frequent cause is autoimmune thyroiditis (known as Hashimoto's thyroiditis), in which the immune system attacks the body's own thyroid tissue.

The most common signs include:

  • persistent fatigue and feeling cold even when others do not;
  • weight gain without any noticeable change in diet;
  • dry skin, brittle hair and hair loss;
  • constipation;
  • slowed thinking, low mood, difficulty concentrating;
  • a deeper or hoarse voice;
  • irregular menstrual cycles in women.

Hyperthyroidism — an overactive thyroid

Here the opposite happens: more hormone is produced than necessary and the body "runs at increased speed". One well-known cause is Graves' disease, which is also autoimmune, but nodules that produce hormones independently can be responsible as well.

  • a rapid or irregular heartbeat;
  • weight loss despite a good appetite;
  • sweating, feeling hot, intolerance to heat;
  • irritability, anxiety, insomnia;
  • trembling hands;
  • muscle weakness, particularly in the thighs;
  • in some cases, changes in the eyes — bulging or irritated eyes.

Goitre — enlargement of the gland

A goitre is an enlargement of the thyroid, which may be accompanied by normal, reduced or increased hormone function. When the gland grows sufficiently, it can press on the surrounding structures and cause a feeling of tightness in the neck, a dry cough, difficulty swallowing or breathing, especially when the patient lies down.

Thyroid nodules

Nodules are small formations within the thyroid tissue. They are very common and in the vast majority of cases they are benign (non-cancerous). Nevertheless, every nodule deserves assessment, because a small proportion may be malignant. They are often discovered incidentally during a neck ultrasound performed for other reasons.

Thyroiditis

These are inflammations of the gland. Some forms follow a viral infection and cause pain at the front of the neck, fever and tenderness to the touch. Others, such as autoimmune thyroiditis, are painless and are detected through blood tests.

Throat and voice signs that should not be ignored

Since the thyroid lies next to the larynx (the voice organ) and to the nerves that control the vocal cords, certain complaints should be assessed without delay:

  • hoarseness lasting more than two to three weeks with no clear cause;
  • a persistent sensation of a "lump in the throat";
  • difficulty or pain when swallowing;
  • asymmetrical swelling or a palpable nodule in the neck;
  • rapid growth of an existing formation;
  • laboured or noisy breathing.

These signs do not necessarily mean serious disease — they often have other causes, such as laryngopharyngeal reflux or ordinary inflammation. But the distinction can only be made through examination.

Who is at higher risk

Thyroid disorders are more common in women than in men, and the risk increases with age. Other factors taken into account during assessment:

  • a family history of thyroid or autoimmune disease;
  • the period after childbirth, when transient thyroiditis may occur;
  • previous exposure to radiation in the neck region;
  • other autoimmune conditions, such as type 1 diabetes;
  • insufficient or excessive iodine intake.

How thyroid disorders are diagnosed

Medical history and clinical examination

Assessment begins with a conversation about the complaints, how long they have lasted and the family history, followed by palpation of the neck to evaluate the size, consistency and mobility of the gland, as well as the presence of enlarged lymph nodes.

Blood tests

Measuring TSH is the first and most informative test; where needed, free T4, T3 and thyroid antibodies are added, the latter helping to identify an autoimmune condition.

Neck ultrasound

This is a painless method without radiation that shows the size of the gland, its structure and the characteristics of any nodules. Ultrasound helps to decide whether a nodule should be monitored over time or whether a biopsy is required.

Fine-needle aspiration

When the ultrasound raises questions, a small sample of cells is taken from the nodule with a very fine needle and analysed by a pathologist. The procedure is performed on an outpatient basis and is usually well tolerated.

Laryngoscopy

If there is hoarseness or surgery is planned, the ENT doctor may examine the vocal cords with a thin optical instrument in order to assess their mobility.

Treatment — what to expect

Treatment depends entirely on the diagnosis, age, general health and examination results. In broad terms:

  • Hypothyroidism is treated with hormone replacement therapy, prescribed and monitored by an endocrinologist.
  • Hyperthyroidism may be treated with medication, with radioactive iodine or, in certain cases, with surgery.
  • Benign nodules are often simply monitored periodically with ultrasound and blood tests.
  • A large goitre with compressive symptoms or suspicious nodules may require surgical intervention.

None of these decisions is made without an individual assessment. Self-medication, stopping therapy without consulting a doctor or taking iodine preparations without an indication may worsen the condition.

When to book an appointment

Consult a specialist if you notice a swelling or nodule in the neck, if your voice has changed for more than two to three weeks, if you have difficulty swallowing or a feeling of pressure in the throat, or if you have persistent symptoms such as unexplained fatigue, weight changes and a rapid heartbeat. At RINO Clinic in Ferizaj, an ENT examination of the neck and larynx helps to determine whether the complaints are related to the thyroid or to other causes, and to guide the further diagnostic steps.

Frequently asked questions

Are thyroid nodules dangerous?

Most thyroid nodules are benign and cause no problems. Nevertheless, a small proportion may be malignant, which is why every nodule that is discovered should be assessed with ultrasound and, where indicated, with fine-needle aspiration. Regular follow-up is the safest way to avoid missing changes in time.

Can the thyroid cause hoarseness?

Yes. An enlarged gland or a formation pressing on the surrounding structures can affect the nerves that control the vocal cords and lead to hoarseness. However, hoarseness has many other causes as well, so an examination of the larynx is needed to identify its source.

Does diet affect thyroid health?

An adequate intake of iodine through food and iodised salt is important for the normal function of the gland. However, excessive intake of iodine or of supplements without an indication can be harmful. Any planned change should be discussed with your doctor.

How often should thyroid tests be repeated?

There is no single answer for everyone. The frequency depends on the diagnosis, on the therapy you are taking and on how stable your values are. Your doctor will determine the interval between check-ups individually.

Does every goitre need surgery?

No. Many goitres are simply monitored with periodic check-ups. Surgery is mainly considered when the gland causes compressive symptoms in the throat or affects breathing, when there is a suspicion of malignancy, or when hyperthyroidism cannot be controlled by other methods.
