Toxic Goiter
In toxic goiter the thyroid over-produces hormones. Symptoms include palpitations, sweating, weight loss and tremor. Treatment options are antithyroid medication, radioactive iodine and surgery — chosen by cause and severity.
Surgery is preferred when antithyroid drugs do not control disease, when there is a large goiter, eye involvement in Graves' disease, pregnancy plans or a suspicious nodule.
Causes
Graves' disease (autoimmune diffuse toxic goiter), toxic multinodular goiter and toxic adenoma are the main causes. Scintigraphy and antibodies help separate them.
Preoperative Control
Hormones should be brought close to normal before surgery to reduce anaesthetic and bleeding risk. Beta-blockers may be added for symptom control.
Symptoms
- Palpitations, fast heart rate
- Sweating, heat intolerance
- Weight loss with normal appetite
- Tremor and anxiety
- Eye changes (in Graves')
- Diarrhoea, menstrual changes
Diagnosis and Assessment
- TSH, free T4, free T3
- TSH-receptor antibodies in Graves'
- Neck ultrasound
- Thyroid scintigraphy
- ECG and cardiology assessment when indicated
Treatment Options
- Antithyroid drugs (methimazole / propylthiouracil)
- Radioactive iodine ablation
- Surgery — total thyroidectomy
When Is Surgery Considered?
- Inadequate response or intolerance to drugs
- Large goiter or pressure symptoms
- Active Graves' eye disease
- Pregnancy planning or pregnancy itself
- Suspicious nodule
Surgical Methods
- Total thyroidectomy is the standard choice
- Intraoperative nerve monitoring
- Parathyroid preservation with meticulous technique
Preoperative Preparation
- Hormone control close to normal
- Beta-blocker as advised
- Anaesthetic assessment
- Stop smoking
Postoperative Follow-up
- Lifelong thyroid hormone replacement
- Calcium and vitamin D as needed
- Hormone titration with regular blood tests
- Endocrinology follow-up
Risks and Safe Surgery
- Voice change
- Low calcium
- Bleeding
- Wound issues
- Worsening of eye disease without proper steroid cover in selected Graves' cases
Process in Antalya
Hormone status, ultrasound, scintigraphy and cardiology assessment are reviewed together; the operation is timed when control is adequate.
When to Seek Urgent Care
- • Very fast or irregular heart rate
- • High fever, severe agitation (thyroid storm signs)
