Thyroid Dysfunction Symptoms & Screening | Hyperthyroidism vs Hypothyroidism Guide
The thyroid gland, a small butterfly-shaped organ in the neck, serves as the "master controller" of your body's metabolism. As we navigate a more mature life stage, maintaining thyroid health becomes a cornerstone of long-term vitality. In Hong Kong’s fast-paced urban environment, thyroid dysfunction—often manifesting as either Hyperthyroidism or Hypothyroidism—is increasingly prevalent among the international community.
What is Thyroid Dysfunction?
Thyroid issues generally fall into two categories, both of which significantly impact your physiological pace and overall quality of life.
| Hyperthyroidism (Overactive Thyroid) |
Hypothyroidism (Underactive Thyroid) |
| The thyroid produces excessive hormones, causing the metabolism to accelerate to an unhealthy speed. | The gland fails to produce sufficient hormones, causing bodily functions to slow down. |
These imbalances can be triggered by autoimmune diseases (such as Graves' Disease or Hashimoto's Thyroiditis), iodine imbalances, certain medications, or the presence of nodules.
Hyperthyroidism vs. Hypothyroidism: Symptom Comparison
| Category | Hyperthyroidism | Hypothyroidism |
| Weight Change | Unexplained weight loss | Unexplained weight gain |
| Emotional State | Anxiety, irritability, tremors | Depression, low mood, "brain fog" |
| Energy Levels | High energy but quick to fatigue | Persistent fatigue, lethargy |
| Heart Rate | Palpitations, rapid heart rate | Slow heart rate (bradycardia) |
| Other Symptoms | Heat intolerance, heavy sweating | Cold sensitivity, dry skin, constipation |
5 Major Health Risks of Untreated Thyroid Dysfunction
Neglecting thyroid health can lead to systemic complications that diminish a "carefree life."
- Cardiovascular Disease: Hyperthyroidism can cause arrhythmias and atrial fibrillation; Hypothyroidism is linked to higher LDL cholesterol and hypertension.
- Fertility & Menstrual Issues: Hormone imbalances can disrupt ovulation and menstrual cycles in women.
- Mental & Cognitive Decline: Hypothyroidism is often linked to memory loss and depression; Hyperthyroidism can cause severe insomnia and chronic anxiety.
- Osteoporosis: Untreated overactive thyroid conditions accelerate bone mineral loss, increasing fracture risks.
- Nodules & Thyroid Cancer: Some dysfunctions are associated with nodules or malignancies that require immediate clinical attention.

Who Needs a Thyroid Check? Screening Essentials
Thyroid issues are statistically more common in women, particularly during life transitions such as pregnancy or menopause. Regular screening is advised for those with a family history, high iodine intake, or prior radiation exposure. For the general public, a checkup every 2-3 years is recommended; however, those at higher risk should undergo an annual examination.
