Frequently Asked Questions
Can you live without a thyroid gland?
Yes, it is possible to live a normal life without a thyroid gland, but you will need to take daily thyroid hormone replacement medication. The thyroid is responsible for producing hormones that regulate metabolism. Without it, the body experiences hypothyroidism.
What happens when your thyroid is removed?
When the entire thyroid is removed (total thyroidectomy) the body is no longer able to produce thyroid hormone, leading to hypothyroidism. This can cause fatigue, weight gain, feeling cold, and other symptoms. Taking synthetic thyroid hormone daily can prevent this.
How is life after thyroid removal surgery?
Most people are able to resume normal life after thyroidectomy following a short recovery period. Some fatigue and voice changes may persist for a few weeks after surgery. Ongoing hormone replacement medication and monitoring of TSH levels are necessary to manage hypothyroidism.
What are the risks of living without a thyroid?
Untreated hypothyroidism from lack of a thyroid gland can lead to problems like goiter, heart disease, infertility, cognitive impairment, and myxedema. Taking supplemental thyroid hormone minimizes these risks and allows people to live healthy lives without a thyroid.
Can hypothyroidism be cured without a thyroid?
No, hypothyroidism cannot be cured in someone who has had their thyroid completely removed. However, synthetic thyroid hormone tablets provide the thyroxine the body needs, controlling symptoms and preventing complications from thyroid deficiency.

The thyroid gland plays an important role in regulating metabolism, growth, and other essential body functions. Located at the base of the neck, this butterfly-shaped gland produces thyroid hormone (thyroxine), which impacts processes throughout the body. But what happens when the thyroid gland is surgically removed?
Though challenging, it is possible to live a normal life without a thyroid. With proper thyroid hormone replacement medication, most people can manage well after thyroid removal and avoid the complications of hypothyroidism.
Why is the Thyroid Gland Removed?
Thyroidectomy, or surgical removal of the thyroid gland, is most often performed to treat thyroid cancer, thyroid nodules, hyperthyroidism, or goiters. The extent of thyroid removal depends on the underlying condition:
- Partial thyroidectomy - removing one lobe of the thyroid
- Near total thyroidectomy - removing nearly all thyroid tissue
- Total thyroidectomy - removing the entire thyroid gland
Other less common reasons for thyroidectomy may include radiation exposure or trauma to the gland. In most cases, the major portion or entire thyroid is removed, leaving the body unable to naturally produce adequate thyroid hormone.
Function of the Thyroid Gland
The thyroid gland uses iodine from your diet to produce two main thyroid hormones: triiodothyronine (T3) and thyroxine (T4). These hormones regulate metabolism, growth, temperature regulation, heart rate, and many other essential processes.
Without enough thyroid hormone, bodily functions slow down in a condition called hypothyroidism. Even partial thyroid removal can lead to hypothyroidism if the remaining tissue cannot meet the body's thyroid needs.
Life After Thyroidectomy: Managing Hypothyroidism
If you've had a complete thyroidectomy or surgery that results in hypothyroidism, taking daily oral thyroid hormone replacement medication is necessary to maintain health and quality of life. The most commonly prescribed medication is levothyroxine (synthetic T4).
Replacement thyroid hormone returns thyroid levels to normal, preventing the symptoms and complications of hypothyroidism. With proper medication and monitoring, most people thrive after thyroid gland removal, despite requiring medication for life.
Recovery After Thyroid Surgery
After having your thyroid removed, be prepared for a recovery period of several weeks before you are fully healed and back to normal activity. Typical symptoms and timeline include:
- Pain and swelling around the incision for 1-2 weeks
- Fatigue and voice changes for up to 6 weeks
- Numbness and tingling that resolves within a few months
Your doctor will closely monitor your condition and adjust medications as needed. Most patients are able to resume regular activity within a couple weeks of surgery. Light walking can help improve post-surgical fatigue and healing.
Monitoring Thyroid Levels
Frequent blood tests are necessary after thyroidectomy to measure thyroid function and calibrate hormone replacement medication dosage. Levels of TSH (thyroid stimulating hormone) and sometimes T3 and T4 are tracked to ensure thyroid levels are ideal.
At first, TSH testing is usually done every 6-8 weeks. Once your replacement hormone dose is stabilized, testing every 6 months to a year is typical. Contact your doctor if you experience symptoms like fatigue, weight changes or feeling cold.
Risks and Complications of Thyroid Removal
For most patients, thyroid removal surgery and subsequent hormone therapy go smoothly. However, there are potential risks and complications to understand before undergoing thyroidectomy:
- Permanent hypothyroidism - Lifelong thyroid medication will be required.
- Parathyroid damage - Accidental removal of these glands can cause calcium issues.
- Recurrent laryngeal nerve injury - This can lead to ongoing voice changes.
- Infection - Infection of the incision site may require antibiotics.
- Scarring- The neck incision results in a thin scar.
Rarely, complications like bleeding or breathing trouble can occur. With an experienced surgeon, risks remain minimal. Following all post-op care instructions lowers complication likelihood as well.
Hypothyroidism Symptoms
Without adequate thyroid hormone replacement, hypothyroidism will occur after thyroidectomy. This causes unpleasant symptoms like:
- Fatigue
- Cold intolerance
- Muscle weakness
- Weight gain
- Depression
- Constipation
- Muscle cramps
- Dry skin and hair
- Impaired memory
Keep in mind that symptoms may initially result from surgery recovery itself. Stay in close contact with your care team. Medication adjustments can resolve lingering issues.
Long-Term Health Concerns
Over time, untreated hypothyroidism from thyroid gland removal can lead to some serious health consequences:
- Goiter - Enlarged thyroid gland due to insufficient hormone levels.
- Heart disease - Increased risk of high cholesterol and heart failure.
- Infertility - Hypothyroidism can disrupt menstrual cycles and sperm counts.
- Birth defects - Dangerous for fetus if hypothyroid during pregnancy.
- Mental impairment - Can progress to dementia if untreated.
- Myxedema - Rare, life-threatening form of advanced hypothyroidism.
Again, ongoing synthetic thyroid hormone administration coupled with regular TSH testing prevents these complications in most patients after thyroidectomy.
Outlook for Patients Without a Thyroid
While managing hypothyroidism presents new challenges, most people go on to live full, healthy lives after thyroid gland removal. In fact, for some patients with hyperthyroidism or thyroid cancer, thyroidectomy improves quality of life.
Being diligent about taking daily thyroid medication, maintaining follow-up thyroid testing, and reporting concerning symptoms to your doctor are key after surgery. Also be sure to discuss optimal calcium and vitamin D intake to support bone health without the help of a thyroid gland.
Finding Balance Without a Thyroid
Adjusting thyroid hormone replacement medication until ideal levels are achieved is critical and can take months. At first TSH will be checked every 6-8 weeks, along with assessing symptoms and modifying dosage as required.
Notice how you feel on each thyroid medication dose. Report any persisting issues like fatigue, weight changes, menstrual irregularities, or depression to your provider right away.
Once your replacement thyroid hormone dose is optimized, you can expect to feel normal again within several months following thyroidectomy. Expect blood tests at least twice a year moving forward to ensure levels remain stable.
Can Thyroid Removal Be Avoided?
For some thyroid conditions like Graves' disease, hyperthyroidism, noncancerous nodules, or small goiters, medications may shrink the thyroid or regulate levels, avoiding thyroidectomy. Radioactive iodine treatment is another alternative to surgery in select cases.
However, if you have thyroid cancer, large goiters, or suspicious nodules, surgery to remove part or all of the thyroid gland along with hormone therapy is typically the best course of action. The benefits outweigh the inconvenience of daily medication.
Seeking Support After Thyroidectomy
Having your thyroid removed is a big adjustment. Before and after surgery, connect with your care team, family, and online support groups to get answers to your questions and concerns. Building a support network can ease the transition.
Stay focused on keeping your TSH in the normal range through thyroid replacement. Over time, you'll get the hang of maintaining your hormone levels and can live a full, enjoyable life without a thyroid gland.
