Endocrinology

Endocrinologists treat thyroid disorders (hypothyroidism, hyperthyroidism, thyroid nodules), diabetes, adrenal insufficiency, Cushing syndrome, pituitary tumors, PCOS, osteoporosis, calcium disorders, and hormonal causes of infertility and growth problems.

See an endocrinologist if you have a thyroid condition that is difficult to manage, uncontrolled diabetes, symptoms of hormonal imbalance such as unexplained weight changes, fatigue, or menstrual irregularities, or if you are diagnosed with a pituitary or adrenal disorder.

Common tests include thyroid function tests (TSH, T3, T4), HbA1c and fasting glucose, cortisol levels, parathyroid hormone, sex hormone panels, insulin levels, thyroid ultrasound, and sometimes dynamic stimulation or suppression tests to evaluate gland function.

Diabetology focuses specifically on diabetes management. Endocrinology is a broader specialty covering all hormone-related conditions including thyroid, adrenal, pituitary, and bone metabolism disorders, with diabetes being one component of the field.

Yes, conditions such as hypothyroidism, Cushing syndrome, PCOS, and insulin resistance can contribute to weight gain. An endocrinologist can identify the hormonal cause through blood tests and imaging, and recommend targeted treatment along with lifestyle modifications.
