What Does an Endocrinologist Do?
The endocrine system comprises a complex network of hormone-producing glands—including the thyroid, pancreas, pituitary, adrenals, and ovaries/testes. Hormones regulate growth, metabolism, energy levels, mood, and reproductive health. When hormonal balances shift, systemic health challenges emerge.
Thyroid Health: Hypothyroidism vs. Hyperthyroidism
- Hypothyroidism (Underactive Thyroid): Insufficient production of thyroxine (T4) and triiodothyronine (T3). Symptoms include unexplained weight gain, severe lethargy, cold intolerance, dry skin, constipation, and depressive symptoms. Managed effectively with daily levothyroxine replacement therapy taken on an empty stomach.
- Hyperthyroidism (Overactive Thyroid): Excessive thyroid hormone secretion causing rapid heartbeat (tachycardia), unintended weight loss, heat sensitivity, tremors, anxiety, and sleep disturbances. Managed with antithyroid medications or radioactive iodine therapy.
Achieving Optimal Glycemic Control in Diabetes
Managing Type 2 diabetes extends beyond monitoring fasting blood glucose. Endocrinologists monitor Glycated Hemoglobin (HbA1c), which reflects average blood sugar levels over the preceding 90 days. Keeping HbA1c below 7.0% (individualized according to age and comorbidities) significantly reduces the risk of microvascular and macrovascular complications affecting the eyes, kidneys, nerves, and heart.
Medical Disclaimer: Hormone replacement and antidiabetic medications require strict medical supervision and regular blood monitoring. Consult an endocrinologist before modifying your doses.
