Symptoms of Thyroid Disease

Thyroid disease develops when the thyroid does not produce enough thyroid hormone. If you are tired, have skin or hair changes, hoarseness, or pain, your doctor may perform a physical test and order blood tests to determine thyroid function.

Thyroid disease develops when the thyroid (a small, butterfly-shaped gland in the front of your neck) does not produce enough thyroid hormone. It can also happen when an abnormal growth forms, resulting in a lump or nodule. Thyroid hormones regulate how your body expends energy. 

If you are tired, have skin or hair changes, hoarseness, or pain, your doctor may perform a physical test and order blood tests to determine thyroid function. If the results of these tests point to a problem, your doctor may order a thyroid scan and uptake. A lump or nodule at your thyroid may be discovered by your doctor. If this is the case, they may use ultrasound imaging or a thyroid biopsy to assess your condition. The type of treatment will be determined by the specific nature of the condition.

Symptoms of Thyroid Disease

  1. Weight gain or loss: One of the most common symptoms of a thyroid disorder is an unexplained weight change. Weight gain may indicate low thyroid hormone levels, a condition known as hypothyroidism. In contrast, if the thyroid produces more hormones than the body requires, you may experience unexpected weight loss. This is referred to as hyperthyroidism. Hypothyroidism is far more prevalent.
  2. Swollen neck: Thyroid disease can be indicated by a swollen neck. A goitre can sometimes cause a swollen neck. A goitre is an enlargement of the thyroid gland, a butterfly-shaped gland located in front of the thyroid.  An enlarged thyroid can be seen as a swelling in the front of the neck, as shown here. Goiters can be caused by a variety of thyroid diseases. Tumors or nodules that develop within the thyroid can also cause goitres.
  3. Changes in Heart Rate: Hormones produced by the thyroid gland have an impact on almost every organ in the body, including the heart. Hypothyroidism causes the heart to beat slowly, whereas hyperthyroidism causes the heart to beat quickly. Thyroid hormone excess can also cause an increase in blood pressure and the sensation that your heart is pounding (palpitations).
  4. Changes in Mood: Thyroid disorders can have an impact on emotions, energy, and mood. Depression, tiredness, and sluggishness are all symptoms of hypothyroidism. Sleep disturbances, irritability, anxiety, and restlessness are all symptoms of hyperthyroidism.
  5. Hair Loss: Hair loss is a common symptom of thyroid disease. Thyroid hormone levels that are too high or too low can both cause hair loss. When the condition is treated, the hair usually grows back.
  6. Body Temperature: Because the thyroid regulates body temperature, hypothyroid patients frequently complain of feeling cold. Hyperthyroidism, on the other hand, is characterised by excessive sweating and aversion to heat.

Who is affected by Thyroid Disease?

Thyroid disease can affect anyone, including men, women, infants, adolescents, and the elderly. It can be present at birth (typically hypothyroidism) or develop as you get older (often after menopause in women). Thyroid disease is extremely common, with an estimated 20 million Americans suffering from some form of thyroid disorder. A woman is five to eight times more likely than a man to be diagnosed with a thyroid condition.

Causes of thyroid disease

Thyroid disease is also classified into two types: The hypothyroidism and The hyperthyroidism. Other diseases that affect the thyroid gland’s function can cause both conditions.

The Hypothyroidism that can be caused by the variety of conditions, or including:

  1. Thyroiditis is a condition in which the thyroid gland becomes inflamed (swells). Thyroiditis can reduce the amount of hormones produced by your thyroid.
  2. Thyroiditis caused by Hashimoto’s: Hashimoto’s thyroiditis is a painless autoimmune condition in which the body’s cells attack and damage the thyroid. This is an inherited disorder.
  3. Postpartum thyroiditis: This condition also affects 5% to 9% of women after childbirth. It can usually be a transient condition.

Hyperthyroidism can be caused by a variety of conditions, including:

  • Graves’ disease: In this condition, the entire thyroid gland may become overactive and produce an excessive amount of hormone.
  • Nodules: The Hyperthyroidism that can be caused by the thyroid nodules that are overactive. The toxic autonomously functioning of the thyroid nodule is are a single nodule, whereas a toxic multinodular goitre is a gland with several nodules.
  • Thyroiditis: This condition can be painful or not at all. The Thyroiditis that causes the thyroid to release the hormones that have been stored there. This can last several weeks or months.
  • Excess iodine: When your body has too much iodine (the mineral used to make thyroid hormones), the thyroid produces more thyroid hormones than it requires. Some medications (such as amiodarone, a heart medication) and cough syrups contain high levels of iodine.
