What is Fatigue or weakness?

[Kavya]

Fatigue is a persistent feeling of tiredness or lack of energy, even after rest. Weakness refers to reduced physical strength or muscle power, making tasks feel more difficult. Both can result from various causes, including lack of sleep, stress, poor nutrition, or underlying medical conditions like thyroid disorders, anemia, or chronic illnesses.
A thyroid specialist typically means an endocrinologist—a doctor who specializes in diagnosing and treating disorders related to hormones, including thyroid diseases.

Common conditions that require a thyroid specialist include:

Hypothyroidism (underactive thyroid)
Hyperthyroidism (overactive thyroid)
Thyroid nodules or goiters
Thyroid cancer
Autoimmune thyroid diseases like Hashimoto's thyroiditis or Graves' disease
You should consult an endocrinologist if you experience symptoms such as:

Fatigue or weakness
Weight changes (unexplained gain or loss)
Hair loss or dry skin
Anxiety, palpitations, or tremors
Neck swelling or discomfort
Menstrual irregularities
They may recommend blood tests (e.g., TSH, T3, T4, and thyroid antibodies), imaging (like an ultrasound), or a biopsy for diagnosis.
