T38.1

Clinical Causes: Accidental overdose of thyroid hormone medications Incorrect dosage prescribed by healthcare providers Intentional misuse or abuse of thyroid hormones for weight loss or performance enhancement Unsuitable or inaccurate substitution of thyroid hormone types Medication interactions leading to increased thyroid hormone activity Manufacturing errors resulting in higher-than-recommended doses

Key Symptoms: Rapid heartbeat (tachycardia) Weight loss despite normal or increased appetite Nervousness, anxiety, or restlessness Sweating and heat intolerance Fatigue and muscle weakness Difficulty sleeping (insomnia) Diarrhea or increased bowel movements Tremors or shaking Hair thinning or loss Potential signs of thyroid excess, such as bulging eyes (exophthalmos) in specific cases

Diagnosis Path: Diagnosis of poisoning or adverse effects involving thyroid hormones involves a combination of medical history assessment, physical examination, and laboratory tests. These may include measuring serum levels of thyroid hormones (T3, T4), thyroid-stimulating hormone (TSH), and other relevant tests to determine hormonal imbalance. Additional tests, such as ECG or imaging, can be used if cardiovascular or structural effects are suspected.

Treatment Protocols: Treatment strategies focus on removing or neutralizing the excess thyroid hormone effects and managing symptoms. Immediate interventions may include: - Discontinuing the offending medication - Supportive care to stabilize vital signs - Use of medications such as beta-blockers to control heart rate and anxiety - In some cases, medications that block thyroid hormone synthesis or block hormone activity - Dialysis or other procedures are rarely required unless there are severe complications Continuous monitoring is essential to ensure hormone levels return to normal and to prevent long-term consequences. Patients should follow medical guidance closely and avoid self-adjusting medication without consulting healthcare providers.
