What Is Hypothyroidism?
Hypothyroidism, also known as an underactive thyroid, is a condition in which the thyroid gland does not produce enough thyroid hormones. The shortage slows down your metabolism, which changes how your body uses energy.
The thyroid gland sits at the front of the neck and helps regulate heart rate, body temperature and energy levels.
In Singapore, thyroid disorders affect approximately 5 to 10 percent of the population, with women at higher risk, especially as they age. The good news is that hypothyroidism can be effectively managed with proper diagnosis and treatment.
Hypothyroidism Causes
In Singapore, the most common
cause of hypothyroidism is Hashimoto's disease, an
autoimmune disorder where the immune system attacks the thyroid gland,
impairing its ability to produce hormones. Other causes include thyroid
surgery, radiation therapy, and certain medications. Iodine deficiency can
also contribute to the development of hypothyroidism.
Additionally, conditions such as thyroiditis
(inflammation of the thyroid gland), congenital thyroid abnormalities, and
pituitary gland disorders can lead to hypothyroidism. Women who are pregnant
or postpartum are also at a higher risk of developing temporary or permanent
hypothyroidism.
Hypothyroidism Symptoms
The symptoms of hypothyroidism can vary in severity and may develop gradually, often going unnoticed in the early stages. Common symptoms include:
- Fatigue and sluggishness
- Unexplained weight gain
- Dry skin and hair
- Cold intolerance
- Depression and memory problems
- Muscle weakness and joint pain
Complications of Hypothyroidism
If hypothyroidism is not treated, it can result in serious health issues, such as anaemia, hoarseness, an enlarged thyroid gland known as goitre, and hearing impairment. It also increases the risk of heart disease, fertility problems, and myxoedema coma, a rare but potentially life-threatening condition.
How to Test for Hypothyroidism?
Diagnosing
hypothyroidism typically involves blood tests that measure the
levels of thyroid-stimulating hormone (TSH) and thyroid hormones (T4 and
T3).
Additional tests, such as thyroid antibody tests, may be conducted to
determine if an autoimmune disorder like Hashimoto's disease is the cause.
Imaging studies, such as thyroid
ultrasound or radioactive iodine uptake tests, may also be utilised
to assess the thyroid gland's structure and function.
Hypothyroidism Treatment
The primary treatment for hypothyroidism is thyroid hormone replacement
therapy, usually in the form of medication such as levothyroxine. This
medication is taken daily and helps to restore normal hormone levels,
alleviating symptoms and preventing complications.
The dosage of thyroid
hormone replacement is tailored to each patient based on their individual
needs, and regular monitoring of thyroid levels is essential to ensure
effective management.
For most individuals, treatment is lifelong, and periodic adjustments to the
dosage may be necessary.
