Can You Live Without a Thyroid?

The thyroid gland is a small, butterfly-shaped gland located at the base of your neck. It produces hormones essential for regulating metabolism, growth, and energy production. While the thyroid gland is responsible for many important functions, it is possible to live without one. However, managing life after thyroid removal does require commitment and adherence to a treatment plan that includes daily medication, healthy lifestyle choices, and periodic testing. 

What Does the Thyroid Gland Do?

Located at the base of your neck, the thyroid produces two key hormones – thyroxine (T4) and triiodothyronine (T3). These hormones circulate in your bloodstream and affect nearly every cell and organ.

Thyroid hormones primarily regulate your metabolism – converting food and oxygen into energy. They control how quickly or slowly your body uses energy, which impacts your weight, temperature, heart rate, and more. The thyroid also supports growth and development.

The following section will discuss some of the reasons why someone might need to have their thyroid removed.

Why Would Someone Need to Remove Their Thyroid?

There are several reasons why the thyroid may need to be surgically removed, including:

  • Thyroid cancer – Thyroid cancer is one of the most common endocrine cancers, with over 50,000 cases diagnosed annually in the U.S. Removal of the thyroid (thyroidectomy) is a common treatment.
  • Hyperthyroidism – An overactive thyroid that produces too much thyroid hormone is called hyperthyroidism. It can be treated with antithyroid medication, radioactive iodine, or thyroidectomy.
  • Goiters or nodules – Abnormal enlargement of the thyroid gland is called a goiter. Multiple lumps within the thyroid are termed nodules. If suspicious, the thyroid may be removed.
  • Graves’ disease – This autoimmune disorder often leads to hyperthyroidism. Thyroidectomy may be needed if antithyroid drugs do not work.

The good news is – there are treatment options available now if you want to avoid thyroidectomy. You can go for radiofrequency ablation which has several benefits over traditional surgery, including lower risk of complications, quicker recovery, and no need for general anesthesia.

Life After Thyroid Removal Surgery

Following the removal of your thyroid, you’ll need to implement some significant lifestyle changes. Here’s what you should anticipate:

Immediate Effects

Soon after surgery, you’ll begin exhibiting signs and symptoms of an underactive thyroid or hypothyroidism:

  • Fatigue
  • Sensitivity to cold
  • Constipation
  • Dry skin and hair
  • Weight gain
  • Impaired memory and concentration
  • Depression

Swelling and pain around the incision site are also common immediately post-surgery. Most patients need to stay in the hospital for 1-2 days.

Long Term Effects

Since the thyroid can no longer produce hormones, you will need to take thyroid hormone replacement medication daily. Levothyroxine drugs like Synthroid or Levoxyl contain synthetic thyroxine (T4).

Without this supplemental hormone, hypothyroid symptoms will persist and worsen over time. You’ll need regular blood work to monitor thyroid levels.

Long-term risks associated with thyroid removal include:

  • Increased chance of depression and anxiety
  • Higher cholesterol levels
  • Greater risk of heart disease and infertility
  • More likelihood of osteoporosis


How to Manage Life Without a Thyroid

By making certain lifestyle adjustments and working closely with your healthcare providers, you can minimize the effects of hypothyroidism. Here are some tips:

Take Thyroid Medication Consistently – Thyroid hormone replacement drugs must be taken daily on an empty stomach. Missing doses can allow hypothyroid symptoms to return. Inform your doctor of any side effects.

Exercise and Control Weight – Lack of thyroid hormones slows metabolism, so maintaining a healthy weight requires regular exercise and mindful eating.

Eat a Nutritious Diet – Omega-3 fatty acids, selenium, zinc, and vitamin D are particularly important. Limit consumption of soy and foods high in fiber, calcium, and iron, as these hinder the absorption of synthetic thyroid hormones.

Undergo Regular Testing – Blood tests to evaluate TSH, T4, and T3 levels should be done yearly or as recommended by your endocrinologist. This allows for medication adjustments as needed.

Manage Stress – Chronic stress takes a toll on overall health, so incorporate relaxation techniques like meditation, yoga, and deep breathing exercises. Get 7-9 hours of sleep nightly.

Connect with Support Groups – Organizations like Thyroid Cancer Survivors’ Association and ThyCa offer community support for those living without a thyroid. Feelings of isolation or depression can be addressed through forums and local meetings.

Specific Impacts on Health and Daily Life

Weight Gain and Metabolism

With hypothyroidism, metabolism slows significantly, causing more calories to be stored as fat. Losing weight becomes extremely difficult. You’ll need to be disciplined about diet and exercise. Calorie restriction can be necessary to avoid obesity.

Energy Level and Mood

Thyroid hormone deficiency can leave you feeling exhausted. Depression, anxiety, and reduced motivation are common. Hyperthyroidism causes nervousness, irritability, and rapid heartbeats. Keeping TSH levels optimal will help stabilize mood.

Pregnancy and Fertility

Untreated hypothyroidism raises the risk of infertility, miscarriage, and birth defects. If you are trying to conceive or are pregnant, thyroid levels must be closely monitored and medications adjusted by your doctor.

Mental Health

Hypothyroidism is linked to a higher incidence of depression and bipolar disorder. Memory and concentration problems may occur. Discuss any mood changes or thinking challenges with your provider. Proper thyroid treatment often relieves these psychiatric symptoms.

Key Takeaways

In summary, the thyroid gland regulates metabolism, growth, and energy production until disease or dysfunction necessitates its removal. Managing hypothyroidism after thyroidectomy requires daily thyroid hormone medication, healthy lifestyle choices, and periodic testing. But with proper treatment, most people can enjoy restored well-being and a normal life despite not having a thyroid.
