When you undergo a complete thyroid removal, it affects your body. The thyroid gland controls the growth, metabolism, and development of your body. After the surgery, your body will no longer produce thyroid hormones. You’ll need to take synthetic thyroid hormones for the rest of your life.
Thyroid removal (thyroidectomy) is the removal of part or the entire thyroid gland. The procedure may be necessary for reasons such as hyperthyroidism, thyroid cancer, and benign growth. While surgeons can’t guarantee a 100% outcome for each procedure, various factors determine life expectancy after the surgery. These factors include;
Type of Your Condition
The underlying health condition of a thyroidectomy plays a key role in life expectancy after thyroid removal. For example, if you have thyroid cancer, the stage of your cancer and the effectiveness of the subsequent treatment affect prognosis and life expectancy.
Papillary thyroid cancer has a good prognosis. The American Cancer Society (ACS) research shows that the 5-year survival rate is more than 99% for localized cancer cases and 71% for cancer cases with distant spread. A 2023 study featured in the Frontiers in Oncology followed 504 patients with differentiated thyroid cancer. It found that those patients who were disease-free after treatment had normal life expectancy.
Age and Overall Health
A patient’s age and health can affect their life expectancy after thyroid removal. For example, older adults with advanced-stage thyroid cancer or a chronic medical condition may have lower chances of survival than healthier individuals.
However, many large population studies, such as those using SEER database records, show that 86% of patients who have undergone thyroid removal don’t experience a significant change in their life expectancy. This is particularly true if they’re treated early and monitored closely.
Hormone Replacement Therapy
After thyroid removal, your body will not be producing thyroid hormones naturally. To compensate, you (the patient) will be prescribed a lifelong thyroid hormone replacement therapy, like levothyroxine. Proper dosing and consistency are essential to maintaining good health.
Research shows that patients who maintain consistent thyroid hormone levels through proper medication and monitoring have a normal life expectancy. However, incorrect dosing may cause health complications such as weight changes, cardiovascular problems, fatigue, or depression.
In older adults, overtreatment with thyroid hormone has been linked to a higher mortality rate. This emphasizes the need for careful dosage and careful patient management.
Life after Thyroid Removal
You can live a healthy, fulfilling life after thyroid removal if you follow the recommended post-surgery care and long-term lifestyle changes. Your healthcare provider may recommend regular exercise, a balanced diet, and frequent check-ups. If thyroid removal is necessary to address health issues like goiters, hypothyroidism, or thyroid cancer, professional care is crucial for your long-term health.
