Understanding Thyroid Disorders: Causes, Symptoms, Diagnosis & Treatment
Published by: Laksha Medical Centre
What is the Thyroid?
The thyroid is a small, butterfly-shaped gland located at the front of your neck. It produces hormones that regulate your body’s metabolism, energy levels, heart rate, body temperature, and growth. When the thyroid gland doesn’t function properly, it can affect almost every organ in the body.
Thyroid disorders are common and can affect people of all ages, especially women.
Types of Thyroid Disorders
Hypothyroidism (Underactive Thyroid)
Hypothyroidism occurs when the thyroid gland does not produce enough thyroid hormones. This slows down the body’s metabolism.
Common Symptoms
- Fatigue and weakness
- Weight gain
- Feeling cold easily
- Dry skin and hair
- Constipation
- Depression or low mood
- Puffy face
- Slow heart rate
- Memory problems
Hyperthyroidism (Overactive Thyroid)
Hyperthyroidism occurs when the thyroid produces too much hormone, causing the body’s metabolism to speed up.
Common Symptoms
- Unexplained weight loss
- Rapid or irregular heartbeat
- Excessive sweating
- Anxiety or nervousness
- Tremors
- Increased appetite
- Difficulty sleeping
- Heat intolerance
- Frequent bowel movements
Thyroid Nodules
Thyroid nodules are lumps that develop in the thyroid gland. Most are harmless, but some may require further evaluation.
Symptoms
- Lump in the neck
- Difficulty swallowing
- Hoarseness of voice
- Neck discomfort
Goitre
A goitre is an enlargement of the thyroid gland that may occur due to iodine deficiency, autoimmune disease, or thyroid dysfunction.
Causes of Thyroid Disorders
Several factors can affect thyroid function, including:
- Autoimmune diseases (Hashimoto’s thyroiditis, Graves’ disease)
- Family history
