How To Heal Your Thyroid

Should You Ignore Your TSH?

Based on the results of the TPOAbs test, the doctor will recommend certain treatment measures if necessary.

However, there are many things you can do on your own in order to prevent or lower the levels of antibodies. These measures can help delay progression or aid management of autoimmune thyroid conditions. Below, you can see some useful suggestions:

  • Modify your diet the first and most important thing you can do to lower levels of TPO antibodies is to modify your diet. Make sure to lower or avoid intake of heavily processed and refined foods, GMO foods, and foods laden with thickening agents, artificial sweeteners, thickening agents, food dyes, among others. Instead, try to include organic fruits and vegetables into your diet and other foods that are rich in nutrients and with amazing anti-inflammatory activity. You also need to consume fiber-rich foods which are beneficial for the digestive system i.e., your gut. Additionally, your diet also needs protein which assists in the repair of tissues in the body, participates in the transport of thyroid hormones throughout the body

When To Take Thyroid Medications To Get Accurate Lab Results

  • TSH– This is a pituitary hormone that responds to low/high amounts of circulating thyroid hormone. In advanced cases of Hashimoto’s and primary hypothyroidism, this lab test will be elevated. In the case of Graves’ disease the TSH will be low. People with Hashimoto’s and central hypothyroidism may have a normal reading on this test.
  • Free T3 & Free T4-These tests measure the levels of active thyroid hormone circulating in the body. When these levels are low, but your TSH tests in the normal range, this may lead your physician to suspect a rare type of hypothyroidism, known as central hypothyroidism.

Can Hypothyroidism Go Away On Its Own

In some mild cases, you may not have symptoms of hypothyroidism or the symptoms may fade over time. In other cases, the symptoms of hypothyroidism will go away shortly after you start treatment. For those with particularly low levels of thyroid hormones, hypothyroidism is a life-long condition that will need to be controlled with medication on a regular schedule. It can be controlled very well and you can live a normal life with hypothyroidism.

When And How You Take Your Pill

If you’re taking your thyroid replacement or antithyroid medication at different times each day, you might not be consistent about taking it on an empty stomach as recommended. Food may delay or reduce the drug’s absorption by changing the rate at which it dissolves or by changing the stomach’s acid balance, ultimately affecting your thyroid hormone levels, your symptoms, and your test results.

If you want to ensure the best possible absorption of your medication, take your thyroid medication consistently. Ideally, you should take your thyroid medicine in the morning, on an empty stomach, about one hour before eating breakfast and drinking coffee, or at bedtime .

Also, make sure to wait for at least three to four hours between taking thyroid medication and taking any fiber, calcium, or iron-rich foods or supplements, as they can prevent you from absorbing your full dose of medication.

Ultimately, when it comes to how you take your thyroid hormone drug, consistency is what you should strive for. If you plan to change the way you take your thyroid medication, make sure you clear it with your doctor first.

How Is Hypothyroidism Treated


To make matters even more confusing, we still do not recommend universal treatment for people who have subclinical hypothyroidism: slightly elevated TSH and normal free T4.

Even though subclinical hypothyroidism is associated with worse health outcomes, treatment with thyroid hormone medicine may not significantly improve a persons symptoms and quality of life.

From my perspective, more lab testing may cause anxiety, generate further tests, and lead to unnecessary treatment, which can cost hundreds, and sometimes thousands, of dollars. We have good solid evidence to support simple tests to diagnose hypothyroidism and follow people who need treatment for it. I recommend questioning any doctors who recommend tests that are not supported by clinical research. While it may sound like a good idea to check more biomarkers, its important to understand the limitations of weak evidence before embarking on this journey.

What Are They Symptoms Of An Overactive Thyroid

An overactive thyroid is a condition called Hyperthyroidism and is where the thyroid is overactive and produces too much of the thyroid hormones.

When too much of the T3 and T4 hormones are produced, the following symptoms can occur:

  • Feeling nervous, anxious or irritable
  • Weight loss
  • Irregular or heavy periods

What Is A T4 Test

T4 Tests A Total T4 test measures the bound and free thyroxine hormone in the blood. A Free T4 measures what is not bound and able to freely enter and affect the body tissues.

What does it mean if T4 levels are abnormal? Importantly, Total T4 levels are affected by medications and medical conditions that change thyroid hormone binding proteins. Estrogen, oral contraceptive pills, pregnancy, liver disease, and hepatitis C virus infection are common causes of increased thyroid hormone binding proteins and will result in a high Total T4. Testosterone or androgens and anabolic steroids are common causes of thyroid hormone binding proteins and will result in a low Total T4.

In some circumstances, like pregnancy, a person may have normal thyroid function but Total T4 levels outside of the normal reference range. Tests measuring free T4 either a free T4 or free T4 index may more accurately reflect how the thyroid gland is functioning in these circumstances. An endocrinologist can determine when thyroid disease is present in the context of abnormal thyroid binding proteins.

Things You Should Know If You Have A Thyroidectomy

I’ve treated hundreds of thyroid patients in my clinical practice and I’ve run into many patients without a thyroid.

These patients are certainly more difficult to treat than run of the mill thyroid patients but I’ve learned much in my years of treating them.

While they are more difficult, it’s still possible to help them lose weight and feel better.

It just takes the right approach…

With that in mind, here are 5 things that I think you should know if you’ve had your thyroid removed based on THIS experience.

#1. You are now HYPOTHYROID.

This is probably the single most important thing that you understand if your thyroid has been removed.

Once your thyroid is removed you are now considered to be HYPOTHYROID.

It doesn’t matter WHY your thyroid was removed, once it is removed you now have a sluggish thyroid.

I don’t care if your thyroid was removed because you WERE hyperthyroid .

Thyroid removal is considered to be a cure for hyperthyroidism but once your thyroid is out you’ve effectively traded hyperthyroidism for hypothyroidism.

What does it mean to be hypothyroid?

It means that you are reliant upon thyroid medication.

And because doctors do a terrible job at replacing lost thyroid hormone once the thyroid has been removed, you will probably always feel a little bit hypothyroid .

This is so important because many people will read my blog posts and if they’ve had their thyroid removed they will ask if it applies to them.

#2. T4 isn’t enough by itself for you.

Treatment Of Thyroid Issues

How Thyroid Medication Changes your Blood Pressure

If hypothyroidism is diagnosed, you will usually begin taking levothyroxine a synthetic, man-made version of the thyroid hormone thyroxine.

If hyperthyroidism is diagnosed, however, treatment options include:

  • Antithyroid Drugs
  • Surgery to remove some of or all the thyroid gland
  • Radioactive iodine to reduce the thyroids activity

As mentioned above, when treatment commences, it is likely you will have blood tests on a regular basis, possibly every few weeks to assess your bodys response to treatment. Once the treatment has made your condition stable, the frequency of the blood tests should reduce.

Managing And Monitoring Subclinical Hypothyroidism

Tests for people with confirmed subclinical hypothyroidism


1.5.1 Consider measuring TPOAbs for adults with TSH levels above the reference range, but do not repeat TPOAbs testing.

Treating subclinical hypothyroidism

1.5.2 When discussing whether or not to start treatment for subclinical hypothyroidism, take into account features that might suggest underlying thyroid disease, such as symptoms of hypothyroidism, previous radioactive iodine treatment or thyroid surgery, or raised levels of thyroid autoantibodies.


1.5.3 Consider levothyroxine for adults with subclinical hypothyroidism who have a TSH of 10 mlU/litre or higher on 2 separate occasions 3 months apart. Follow the recommendations in section 1.4 on follow-up and monitoring of hypothyroidism.

1.5.4 Consider a 6-month trial of levothyroxine for adults under 65 with subclinical hypothyroidism who have:

  • a TSH above the reference range but lower than 10 mlU/litre on 2 separate occasions 3 months apart, and

  • symptoms of hypothyroidism.If symptoms do not improve after starting levothyroxine, re-measure TSH and if the level remains raised, adjust the dose. If symptoms persist when serum TSH is within the reference range, consider stopping levothyroxine and follow the recommendations on monitoring untreated subclinical hypothyroidism and monitoring after stopping treatment.

Thyroid Peroxidase Antibodies Test And Who Needs It

Thyroid peroxidase antibodies test measures the level of an antibody that is directed against TPO.

These antibodies are produced in the body by the immune system, as mentioned above.

The TPO antibodies test serves multiple purposes, such as:

  • Helping doctors diagnose autoimmune thyroid disorders
  • Aiding in differentiating autoimmune thyroid disorders from non-autoimmune hypothyroidism or goiter
  • Serves as a diagnostic tool in deciding whether to treat a patient who has been diagnosed with subclinical hypothyroidism

Doctors may also order a TPO antibodies test if you are pregnant and have an autoimmune disease, particularly the condition that involves thyroid.

Thyroid peroxidase antibodies have been associated with reproductive difficulties such as miscarriage, preeclampsia, premature delivery, and in-vitro fertilization failure. In these instances, the doctor may also order TPOAbs test, but bear in mind its not a standard test for problems with fertility and pregnancy.

If a pregnant woman has an autoimmune thyroid condition or some other autoimmune disease with thyroid involvement, the doctor may order TPO antibodies test in order to determine whether the baby could be at risk of thyroid dysfunction.

Additionally, you might need a TPO antibodies test if other thyroid hormone levels are too low or too high. Your doctor will need results from TPO antibodies test to determine whether an autoimmune condition impaired the production and concentration of thyroid hormones.

Factors Which May Influence Your Dose

Let’s say you are someone who has been on a steady dose of thyroid medication for a year or more.

Now let’s assume that you have found out recently that your dose of thyroid medication needs to be adjusted.

What could potentially explain the reason for this change?

There are many, but I’ve included just a few below for reference:

These factors aren’t necessarily listed in terms of importance but I can tell you from my own personal experience that stress and weight changes probably play the biggest role.

I constantly remind my patients who are losing weight, especially those who have lost more than 50 pounds, that they are a completely different person than they were 50 pounds ago from a metabolic standpoint.

Blood pressure, cholesterol, metabolic function, thyroid function, etc. will ALL be impacted by changes in weight!

Don’t be surprised, then, if you require less thyroid hormone during weight loss .

It should be noted, however, that if you lose weight the wrong way you may need more thyroid medication to compensate for damage you may have done to your metabolism.

Stressful situations, such as those which just randomly occur in life, also seem to play an important role.

I can’t tell you the number of patients that I’ve seen who need medication adjustment due to things like divorce, stress related to their children, acting as a caretaker for a family member, and death of loved ones.

Is It Time To Change Your Thyroid Medication

7 Signs of an Underactive Thyroid

Inside: Signs that its time to change your Thyroid Medicine. What are the Alternatives to Levothyroxine?

Hypothyroidism is a very common condition and the most common treatment at this point in time is the use of a medicine called levothyroxine.

But are there alternative medications to levothyroxine or which medicine is best for thyroid?

These are the questions that several people suffering from thyroid dysfunction have. So the answer is that yes there are alternatives to levothyroxine and the best medicine for thyroid depends on several parameters.

There can be several reasons for finding an alternative to levothyroxine but one of the major ones being uncontrolled symptoms. Patients on levothyroxine report that their symptoms are not improved completely for sometimes they actually worse.

The other reason to change the medicine is that levothyroxine might not be the right medicine for your thyroid condition.

But how do you know that its time to change your thyroid medicine. Or what are the signs that thyroid medication is too low?

What Are The Symptoms Of A Thyroid Nodule

Most thyroid nodules do not cause symptoms. Often, thyroid nodules are discovered incidentally during a routine physical examination or on imaging tests like CT scans or neck ultrasound done for completely unrelated reasons. Occasionally, patients themselves find thyroid nodules by noticing a lump in their neck while looking in a mirror, buttoning their collar, or fastening a necklace. Abnormal thyroid function tests may occasionally be the reason a thyroid nodule is found. Thyroid nodules may produce excess amounts of thyroid hormone causing hyperthyroidism . However, most thyroid nodules, including those that cancerous, are actually non-functioning, meaning tests like TSH are normal. Rarely, patients with thyroid nodules may complain of pain in the neck, jaw, or ear. If a nodule is large enough to compress the windpipe or esophagus, it may cause difficulty with breathing, swallowing, or cause a tickle in the throat. Even less commonly, hoarseness can be caused if the nodule invades the nerve that controls the vocal cords but this is usually related to thyroid cancer.

The important points to remember are the following:

  • Thyroid nodules generally do not cause symptoms.
  • Thyroid tests are most typically normaleven when cancer is present in a nodule.
  • The best way to find a thyroid nodule is to make sure your doctor checks your neck!

How Much Does A Thyroid Test Cost

Private thyroid testing might not cost as much as you expect. And you may also be surprised to hear you can carry out the test itself using a finger prick kit at home, saving the cost and inconvenience of visiting a clinic.

Our advance thyroid test is £65 and as well as testing for FT3, FT4 and TSH it also tests for Thyroglobulin Antibodies and Thyroid Peroxidase Antibodies.

What Is The Thyroid Gland

The thyroid gland is a butterfly-shaped endocrine gland that is normally located in the lower front of the neck. The thyroids job is to make thyroid hormones, which are secreted into the blood and then carried to every tissue in the body. Thyroid hormones help the body use energy, stay warm and keep the brain, heart, muscles, and other organs working as they should.

Reasons For Fluctuating Thyroid Hormone Levels

Is Your Thyroid Why You Are Not Feeling Well?

Thyroid disease can progress or stabilize as the year’s pass due to any number of reasons:


One of the most common contributing factors of fluctuation in your thyroid levels is your age. As we age, especially women, our thyroid function tends to slow down. According to Harvard Health, of women between the ages 35 and 65, “About 13% of women will have an underactive thyroid, and the proportion rises to 20% among those over 65”. A person’s age at the onset of a thyroid condition often plays a role in their treatment. Many of the symptoms associated with hypothyroidism resemble the typical side-effects of aging, which may delay treatment. Many women attribute their fatigue, weight gain, and brittle hair and nails to menopause instead of a thyroid issue. Therefore, they may not raise the issue with their doctor or seek treatment.

Medication dosage and potency

Your thyroid levels may also vary due to medication type, potency, and dosage. Variances such as a change in health plans, change in primary care physician, or change in thyroid medication formulations may lead to an adjustment in your thyroid medication dosage or potency. Switching to a new brand of thyroid medication may lead to fluctuation in thyroid levels as your body adjusts.

Interactions with other medications

Some prescription meds that can influence thyroid hormones:

We suggest regular monitoring of your thyroid function during the long-term use of any of the therapies listed above.

Does Thyroxine Treatment Have Side Effects

No good-quality research is available on the side effects of treating subclinical hypothyroidism with thyroxine, but it’s generally considered to be a well-tolerated drug. Because the body usually produces this hormone on its own, there are no problems if the dose is correct. If it’s too high though, side effects can’t be ruled out. Possible side effects include heart problems like or a racing heartbeat.

What Is A Normal Range For A Thyroid Test

Laboratories use reference ranges when analysing the function of the thyroid. Typical reference ranges for a healthy individual may look like this:

  • TSH 0.27 4.2 mIU/L
  • FT4 12.0 22.0 pmol/L
  • FT3 3.1 6.8 pmol/L

Different laboratories use different reference ranges, but if your results fall outside of these parameters you could be diagnosed with hypothyroidism or hyperthyroidism.

Subclinical hypothyroidism, on the other hand, occurs when your blood TSH level is slightly raised but your FT4 is within the normal range.

Staying On Top Of Thyroid Lab Testing

One of the most important things you can do as a thyroid patient is to simply keep an eye on your thyroid function.

And the way you do that is by regularly checking your thyroid lab tests.

Your thyroid lab tests, if coupled with your symptoms, can be a great way to keep an eye on your medication and your dose.

Your labs can and should act as a warning sign for trouble and will help you make any decisions.

Of course, this assumes that you are getting the right lab tests and looking at factors such as T4 to T3 conversion, reverse T3, inflammatory levels, and thyroid antibodies.

If you are not getting all of these then you will have a hard time figuring out how to adjust your medication appropriately when the time comes.

How often do you need to be checking your lab tests?

Well, in the beginning, when you first starting taking your medication, you may need to get your labs tested as frequently as every 6 to 8 weeks.

But, as time goes on, you can stretch out the interval to every 3-6 months depending on your circumstance.

I find that a good way to approach lab testing, once you’ve been stabilized on a dose, is to do a complete thyroid lab panel every 6 months and smaller spot checks in between as necessary.

If I find that my patients are feeling poorly or going through a stressful time then I will pull the trigger and have them spot test certain lab tests such as total T3, free T3, or reverse T3.

A word of caution:
