Thyroidectomy Recovery, Week by Week: Scar, Voice and Energy

Most people go home one or two days after a thyroidectomy and are back to everyday life within one to two weeks. Australian hospitals generally advise no heavy lifting or hard exercise for about two weeks. A sore throat, a tired or weaker voice and a tight feeling when swallowing are common at first and usually settle over weeks to a few months. The scar fades over a year or more. Your first thyroid test is usually around six weeks after surgery, and it can take a few months to get your dose right.

Whether you are preparing for surgery or a few days out, here is what recovery usually looks like, week by week, what is normal, and the few signs that need help straight away.

When to get help straight away

Serious bleeding into the neck is uncommon, about 1 to 2 in 100 operations, and most happens within hours of surgery while you are still in hospital. But if you notice growing swelling in your neck, trouble breathing or trouble swallowing, call 000.

After a total thyroidectomy, tingling around your lips, fingers or toes, or muscle cramps, in the first few days can mean low calcium. Contact your surgical team or GP the same day. Our guide to tingling and calcium after thyroidectomy explains more.

In hospital: the first day or two

Most people stay one or two nights, though some go home the same or next day. Some hospitals use a small drain in the neck and some don't. Research shows drains don't prevent serious bleeding, and the American Thyroid Association advises against using them routinely, so don't worry if you don't have one. Your team will check your calcium, your voice and your wound before you go home.

A sore throat is common at first. Feeling sick in the first day is also common, and medicines given around the time of surgery reduce the chance of it.

Week one

• Pain: many people manage on paracetamol or ibuprofen. Stronger pain medicines can cause constipation, so drink plenty of water.
• Eating: soft foods are easier while your throat is sore. Our guide to what to eat after a thyroidectomy has ideas.
• Neck: stiffness is normal. Gentle movement helps, and you will be able to turn your head more each day.
• Voice: it may be weaker, huskier or tire easily. More on this below.
• Your tablet: after a total thyroidectomy you will usually start levothyroxine within a day or so of surgery. Take it with water, at least 30 minutes and preferably 60 minutes before food.

Weeks one to two

Cancer Council says most people return to their usual activities within one to two weeks, though recovery can take longer. Advice on work varies by hospital and type of job, from about one to two weeks. Walking is encouraged as soon as you feel up to it.

Advice on lifting and exercise differs between hospitals. Princess Alexandra Hospital and Cancer Council suggest avoiding heavy lifting and strenuous exercise for a couple of weeks, Mater says two weeks, and Head and Neck Cancer Australia suggests a month for heavy lifting, strenuous exercise and contact sports. Ask your own team what they recommend.

For driving, the usual guidance is to wait until you can turn your head comfortably, are no longer taking strong pain medicines, and your surgeon is happy. Mater advises getting clearance from your surgeon first.

Your voice

A weaker, tired or lower voice in the first weeks is common, even when the voice nerves are fine. In one study of nearly 400 people, about half noticed some voice change after surgery without any nerve injury, and most had recovered within five months.

Temporary weakness of a voice nerve affects about 1 in 10 people in pooled studies. Permanent change is uncommon, at around 0.3 to 3% across studies, and 0.4% in a recent Melbourne series. If your voice is still hoarse or weak a couple of weeks after surgery, or you cough when you drink, ask for your vocal cords to be checked. ENT specialists and speech pathologists help with this.

Swallowing

Swallowing can feel tight or lumpy for a few weeks. Across 35 studies, swallowing problems peaked straight after surgery and returned to pre-surgery levels for most people within two to three months, though a smaller group still noticed them at a year. If swallowing is getting worse rather than better, contact your team.

Your scar

The scar usually looks red and feels firm at first, and may thicken for a few weeks before softening over the following months. It keeps fading for a year or more. Cancer Council suggests keeping it moisturised and out of the sun. Paper tape, silicone gel or sheets and gentle massage are often suggested once the wound has healed, though the evidence for them is modest. Most people end up happy with how their scar looks, even if it matters a lot in the early months. Ask your surgeon before starting anything on the wound.

Energy and your first thyroid test

Thyroid levels take about six weeks to settle, so your first test is usually around six weeks after surgery, with some services suggesting six to eight. It is very common for the first dose to need adjusting, and it can take a few months to get it right. If you feel hot, shaky or wired, or very flat and tired, tell your doctor rather than waiting it out. Our guide to levothyroxine side effects and dose signs explains what to look for.

Tiredness after a total thyroidectomy is common and can last months for some people. An Australian study from Newcastle found wellbeing scores were still below population norms a year after thyroid cancer surgery. If you are still exhausted once your results are in range, raise it with your doctor. Our guide to fatigue after thyroidectomy covers what to check.

After a hemithyroidectomy

If only one side was removed, recovery is often quicker, and low calcium is rare. You may not need a thyroid tablet at all, but about 1 in 4 people end up needing one, usually within the first six months, according to an Australian review. Your levels will be checked to find out.

If you had thyroid cancer

Some people go on to have radioactive iodine a few weeks or months after surgery. Our guide to radioactive iodine and the low-iodine diet explains what to expect. The emotional side of a thyroid cancer diagnosis and surgery is real too. Our guide to the emotional side of thyroidectomy may help.

Where ThyroBase fits

Recovery from surgery is guided by your surgical team, and no food or powder speeds healing. Once you are settled, ThyroBase is a daily morning and evening nutrition powder, a food rather than a medicine, that sits alongside your thyroid medication, never instead of it. Both serves contain minerals, so keep them several hours away from your tablet. The morning serve contains added vitamin D, so if you are on prescribed calcium or calcitriol, ask your team before starting. Pause it during any low-iodine diet. Here is who ThyroBase is, and is not, designed for.

Most people are back to everyday life in a week or two. The voice, the swallow and the scar take longer, and that's normal.

Frequently asked questions

How long does it take to recover from a thyroidectomy?

Most people go home after one or two nights and are back to everyday activities within one to two weeks. Hospitals generally advise avoiding heavy lifting and hard exercise for about two weeks. Voice, swallowing and the scar can take a few months to settle fully.

When can I drive after a thyroidectomy?

Usually once you can turn your head comfortably, are no longer taking strong pain medicines, and your surgeon is happy for you to drive. Advice varies between hospitals, and some ask you to get clearance from your surgeon first.

Is it normal for my voice to change after thyroid surgery?

Yes. A weaker, tired or lower voice is common in the first weeks, even when the voice nerves are fine, and most of it settles within a few months. If your voice is still hoarse a couple of weeks after surgery, or you cough when drinking, ask for your vocal cords to be checked.

How long does a thyroidectomy scar take to heal?

The wound heals in the first couple of weeks, but the scar keeps changing for a year or more. It usually starts red and firm, then softens and fades. Cancer Council suggests keeping it moisturised and out of the sun.

When is the first thyroid test after a thyroidectomy?

Usually around six weeks after surgery, because that is how long levels take to settle on a new dose. It is common for the first dose to need adjusting, and getting it right can take a few months.

The honest takeaway

A thyroidectomy usually means a short hospital stay and a week or two before everyday life returns. The slower parts are your voice, your swallow, your scar and getting your dose right, and those can take months. Know the emergency signs, give yourself time, and keep talking to your team about anything that isn't improving.

ThyroBase is a nutritional supplement and is not intended to diagnose, treat, cure, or prevent any disease. It is designed to sit alongside your thyroid medication, not replace it.
