Maybe your report says “thyroid” and your first question is how long you will need the tablet. Many people type “kya thyroid theek ho sakta hai” into their phone, and the honest answer depends on which thyroid problem you have.
For what thyroid disorders are, how they are tested and how treatment works overall, see our thyroid hub on symptoms, tests and treatment. If you are not sure which problem you have, our guide to the types of thyroid problems sorts them out.
Is thyroid curable? It depends on the type
“Thyroid” is not one disease. Some problems are temporary, some lifelong but well controlled. American Thyroid Association (ATA) puts it simply: most people take thyroid medicine for life, but if the problem came from a virus or happened after pregnancy, it may go away.
| Type | Can it go away? | What usually happens |
|---|---|---|
| Postpartum thyroiditis (after delivery) | Often | Most women regain normal thyroid function within 12–18 months; about 20% of those who become underactive stay that way |
| Silent (painless) thyroiditis | Often | The same course as after delivery, with a 20% chance of a permanent underactive thyroid |
| Subacute thyroiditis (painful, possibly after a virus) | Usually | About 95% recover fully within 12–18 months; it rarely comes back |
| Thyroid change caused by a medicine | Sometimes | Often settles once the medicine is stopped, which only your doctor can decide |
| Mildly raised TSH with normal free thyroxine (T4), called subclinical hypothyroidism | Often | Many results return to normal on a repeat test (see below) |
| Hashimoto’s hypothyroidism | Usually not | Usually permanent; a daily tablet keeps hormone levels normal |
| Graves’ disease | Sometimes | About half go into remission after 12–18 months of anti-thyroid medicine, but relapse is common |
| Overactive nodules (toxic nodule or multinodular goitre) | Not with medicine | They do not go into remission on anti-thyroid medicine; radioactive iodine or surgery can end the overactivity |
| After the whole thyroid is removed, or radioactive iodine for Graves’ disease | No | The underactive thyroid that follows is permanent and needs a daily tablet for life |
Thyroid cancer is a separate question, covered under life expectancy below.
What can go away: thyroiditis and some mildly raised TSH results
Thyroiditis means inflammation of the thyroid. In three common types, the gland leaks stored hormone, runs low for a while, then usually recovers.
After delivery: postpartum thyroiditis
The ATA describes the typical course: an overactive phase 1–4 months after delivery lasting 1–3 months, then an underactive phase at 4–8 months that may last up to 9–12 months. Most regain normal thyroid function within 12–18 months of symptoms starting, but about 20% of those who become underactive stay that way, and it comes back in 20% of women in later pregnancies.
The Indian Thyroid Society’s pregnancy guideline adds that women who have had it have a much higher risk of permanent hypothyroidism over the next 5–10 years, so keep up regular TSH checks after recovery. It also advises that women with depression after delivery be screened for hypothyroidism.
Guidelines differ slightly on when to try stopping the tablet. The ATA suggests about 6–12 months of treatment, then reducing it to see whether it is still needed. The Indian Thyroid Society calls the duration controversial: try stopping about 1 year after delivery, or continue until your family is complete. Either way, for Indian readers, the attempt is planned with your doctor and checked with a blood test.
Silent and subacute thyroiditis
Silent (painless) thyroiditis follows the same course in men and in women who have not recently been pregnant. Subacute thyroiditis makes the thyroid painful and may follow a virus; the ATA says about 95% recover fully within 12–18 months.
A mildly raised TSH
Subclinical hypothyroidism often settles by itself. In a European study of 2,335 adults aged 65 and over with one raised TSH, 60.8% had a normal TSH about a year later. Even when a second test 3 months apart had confirmed it, 39.9% normalised within a year. A lower starting TSH and no thyroid antibodies made this more likely. The study covered only older adults, so treat it as a signal, not your own odds.
That is why doctors repeat the test before deciding on treatment. Our guide to TSH normal range and how to read your report explains the thresholds.
Hashimoto’s hypothyroidism: usually lifelong, but well controlled
In Hashimoto’s thyroiditis, the immune system gradually damages the thyroid. It is the commonest cause of an underactive thyroid, and the ATA says the hypothyroidism it causes is usually permanent. National Health Service (NHS) says you will usually need treatment for the rest of your life to stop symptoms returning, and that you should be able to live a normal life.
The usual tablet is levothyroxine, a man-made form of the T4 hormone your thyroid would make. It replaces what is missing; it does not repair the gland, which is why TSH rises again if it is stopped. It needs a prescription and blood tests: the ATA advises a check 6–8 weeks after starting or changing the dose. Too much can cause a fast heartbeat, nervousness and weight loss; too little leaves you tired, cold and constipated. Pregnancy usually needs a dose change, so tell your doctor as soon as you plan or confirm one. Our guide to thyroid medicine and how it works covers the tablet in detail.
A normal TSH on treatment means the dose is right, not that the thyroid has healed. Your dose may change over time, the ATA notes, but stopping should happen only with your doctor’s help.
Overactive thyroid: remission, radioactive iodine and surgery
The ATA calls Graves’ disease, the commonest cause of an overactive thyroid, in general controllable and safely treated. Our guide to which thyroid doctor to see explains who usually plans this care.
Graves’ disease and anti-thyroid medicine
Anti-thyroid medicines (carbimazole, its active form methimazole, and propylthiouracil) slow hormone production. The ATA says they do not cure Graves’ disease but control it while you take them. NHS says a course usually lasts 12 to 18 months, though some people need medicine for years or for life.
Remission means hormone levels stay normal after the medicine stops. The 2018 European Thyroid Association (ETA) guideline says maximum remission rates of 50–55% are reached within 12–18 months of treatment. It also cites a meta-analysis in which 52.7% relapsed after anti-thyroid medicine, against 15% after radioactive iodine and 10% after surgery. Normal TSH receptor antibodies (TRAb) before stopping point to a better chance of remission. After a relapse, the guideline recommends radioactive iodine or surgery, though long-term low-dose medicine can be considered.
These medicines carry a rare but serious risk: a sudden fall in white blood cells. Fever or a severe sore throat while taking one needs urgent care and a blood count. NHS warns that carbimazole can harm an unborn baby, so effective contraception is needed while taking it; tell your doctor immediately if you become pregnant. Overactive nodules are different: the ATA says they do not go into remission on these medicines.
Radioactive iodine
Radioactive iodine, taken as a drink or capsule, destroys overactive thyroid cells. NHS calls it highly effective, and most people need a single treatment; the ATA says about 10% need a second dose. For Graves’ disease, the dose is chosen to make the thyroid permanently underactive, so a daily tablet follows for life. It is not used in pregnancy or breastfeeding. NHS advises women to avoid pregnancy for at least 6 months afterwards and men not to father a child for at least 4 months. It can worsen thyroid eye disease, so eye problems change the choice.
Surgery
Removing the whole thyroid ends Graves’ overactivity; for a single overactive nodule, removing half may be enough. Without a thyroid, you need replacement hormone for life; after half is removed, the other half may cope on its own. The ATA lists the main risks: temporary hoarseness in 5–7%, permanent voice-nerve injury in 0.5%, and, after total removal, a 1–3% chance that all four parathyroid glands, which control calcium, are damaged. Choose an experienced thyroid surgeon.
Life expectancy after thyroid removal
If your thyroid was removed for Graves’ disease, a large goitre or a harmless nodule, your outlook is that of a treated underactive thyroid. NHS says people on replacement should be able to live a normal life, and the ATA says that with the right dose you can live a normal, healthy life. NHS adds that an untreated underactive thyroid, or the wrong dose, raises heart and bone risks.
After surgery for thyroid cancer, the outlook depends mainly on the type of cancer, its size and whether it has spread. The ATA says the prognosis for papillary and follicular cancer, which make up most thyroid cancers, is excellent, especially under 55 with a small cancer; when papillary cancer has not spread beyond the thyroid, people rarely if ever die from it. Anaplastic cancer, found in less than 2% of people with thyroid cancer, is the most aggressive. Cancer can return years later, so the ATA advises lifelong monitoring even after successful treatment. Your cancer specialist can explain your own outlook.
How to reduce thyroid: what it usually means
When people ask how to reduce thyroid, they usually mean bringing an abnormal TSH back into range. Treatment does that: the replacement tablet for an underactive thyroid, and the options above for an overactive one.
Food, movement and sleep support your energy, weight, heart and bones, but they cannot replace missing thyroid hormone, switch off Graves’ disease, make Hashimoto’s go away or normalise an abnormal TSH on their own. They help with tiredness and weight that linger once levels are normal. Take your tablet the same way every day (see our guide to tablet timing with chai and breakfast), use iodised salt, and stay active. If weight is part of your worry, check it with our body mass index (BMI) calculator with Indian cut-offs.
Can yoga help?
Yoga can help how you feel, but it has been tested alongside medicine, not instead of it. In an Indian randomised trial of 134 people with hypothyroidism, all taking levothyroxine, 6 months of online yoga improved quality-of-life scores compared with a waiting-list group. The comparison group did no yoga, and the trial did not test stopping the tablet. We found no trial showing that yoga makes hypothyroidism go away.
Is there a permanent home remedy for thyroid?
No. We found no trial showing that any kadha, powder, juice or herbal kit replaces thyroid hormone or ends Graves’ disease. In India, Food Safety and Standards Authority of India (FSSAI) rules do not allow a food to claim it can prevent, treat or cure a disease unless another FSSAI regulation specifically permits it, so a “thyroid cure” label on a food product is a reason for caution. Iodine or kelp capsules can make some thyroid problems worse; the hub’s section on food and iodine explains why. Tell your doctor about any supplement you take.
When to see a doctor
The hub has the full list of thyroid warning signs.
Emergency: get help now (call 112)
- Difficulty breathing with a neck swelling, including swelling of the neck in the hours after thyroid surgery.
- Fever or a severe sore throat while taking anti-thyroid medicine.
- A very fast heartbeat with high fever, severe agitation or confusion, or severe drowsiness and confusion in someone with a severe, untreated underactive thyroid.
Prompt review: within days to a few weeks
- Tingling around the lips or in the fingers, or muscle cramps, after thyroid surgery; these can mean low calcium.
- Yellow eyes or skin, itching or dark urine while taking anti-thyroid medicine. Contact your doctor straight away, because this can signal liver problems.
- Palpitations, weight loss or shaky hands returning after a course of anti-thyroid medicine has ended.
- Pregnancy, or planning one, with any thyroid condition or after radioactive iodine.
- Red, bulging or painful eyes, or double vision.
Routine review
- Tiredness, low mood, weight change or palpitations in the year after delivery.
- A regular TSH check if you have had postpartum thyroiditis.
- You want to reduce or stop your tablet: book a review to discuss it rather than stopping.

Frequently asked questions
Can hypothyroidism go away on its own?
Sometimes. An underactive phase after delivery, after a virus or with silent thyroiditis usually recovers within 12–18 months, and a mildly raised TSH often returns to normal on a repeat test. Hypothyroidism from Hashimoto’s thyroiditis is usually permanent, and so is the underactive thyroid after surgery or radioactive iodine. Your doctor can tell which type you have from your history, antibodies and repeat tests.
Can yoga cure thyroid?
No. Yoga cannot replace missing thyroid hormone or switch off Graves’ disease. In an Indian trial of 134 people with hypothyroidism who all kept taking levothyroxine, 6 months of online yoga improved quality of life compared with no yoga. That makes yoga a useful addition to treatment, not a replacement. We found no trial showing that yoga makes hypothyroidism go away.
Can I stop thyroid medicine if my TSH is normal?
Not on your own. A normal TSH on treatment usually means the dose is right, not that the thyroid has healed, and in Hashimoto’s hypothyroidism TSH tends to rise again without the tablet. After postpartum or other temporary thyroiditis, doctors sometimes plan a trial off treatment after about 6–12 months. The ATA says stopping should happen only with your doctor’s help.
Is thyroid permanent once diagnosed?
Not always. Thyroiditis after delivery or a virus is usually temporary, and about half of people with Graves’ disease go into remission after a course of anti-thyroid medicine. Hashimoto’s hypothyroidism is usually permanent, and so is the underactive thyroid that follows thyroid removal or radioactive iodine for Graves’ disease. Even when it is lifelong, the right dose lets most people live a normal life.
Can thyroid problems after delivery go away?
Usually, yes. The ATA says most women with postpartum thyroiditis regain normal thyroid function within 12–18 months, but about 20% of those who become underactive stay that way, and it can return in later pregnancies. The Indian Thyroid Society notes a higher risk of permanent hypothyroidism over the next 5–10 years, so keep up regular TSH checks.
How to cure thyroid permanently?
It depends on the type. Thyroiditis often settles by itself. Radioactive iodine or surgery can end an overactive thyroid, but they usually leave you needing a daily tablet for life. Hashimoto’s hypothyroidism cannot be cured at present; a daily tablet controls it well. No diet, yoga or home remedy replaces missing hormone, so be wary of anyone selling a permanent fix.
Will I need thyroid tablets for life after radioactive iodine or surgery?
Usually, yes. For Graves’ disease, radioactive iodine aims to make the thyroid permanently underactive, and removing the whole gland leaves no hormone production, so a daily replacement tablet follows for life. If only half the thyroid is removed, the other half may cope on its own. Either way, regular blood tests check the dose, and with the right dose you can live a normal life.
