What Are Clinical Trials For Hypothyroidism

Clinical trialsand other types of clinical studiesare part of medical research and involve people like you. When you volunteer to take part in a clinical study, you help doctors and researchers learn more about disease and improve health care for people in the future.

Researchers are studying many aspects of hypothyroidism, such as

Practice Patience And Ask For Tests

Some people start feeling more energetic and alert within a week or two of starting thyroid hormone but not everyone. It could take a month or two to feel better. And you may have to see your doctor several times for tests of your blood levels of thyroid stimulating hormone and adjustments to your levothyroxine dose to get it just right.²

You Are Anxious And/or Depressed


If you are experiencing increasing anxiety and/or depression, this could be a sign that you need more thyroid hormone or antithyroid drugs. Anxiety can also be a sign of medication-induced hyperthyroidism, indicating that you may be on too high a dosage of thyroid hormone replacement medication. If you are taking a thyroid drug with T3, such as natural desiccated thyroid or liothyronine, you may need to reduce the dosage.

Its Hard To Lose Or Gain Weight

If you are on a diet and exercise program that should result in weight loss, but you arent losing any weight you may need an increased dosage of thyroid hormone medication for your hypothyroidism, or a reduction in antithyroid drugs. If you are trying to gain weight, and despite increased caloric intake, you are not gaining or youre losing weight you may need to increase your dosage of antithyroid drugs to treat your hyperthyroidism.

What Medication Treats Hypothyroidism

The thyroid gland produces two hormones: thyroxine and triiodothyronine . Similarly, thyroid hormone replacement medication also comes in T4 and T3 formulations. In a healthy thyroid gland, the inactive T4 hormone is released into circulation and then converted by the body into the active T3 hormone. Often, treatment for thyroid replacement starts with T4-only formulations, assuming that the body can successfully do the conversion independently.

Suppose your body has a hard time converting T4 to T3, or you take an interfering medication. In that case, standard T4 medicines may not be sufficient for you. For the few patients who do not feel completely normal taking a synthetic preparation of T4 alone, the addition of T3 may be of benefit.

Those who are interested in a more natural approach may prefer combination therapies. There are two main types of combination thyroid medications – desiccated and compounded.

  • Compounded thyroid medication is a personalized medication in which drug ingredients are combined, mixed, or altered to solve specific patient needs.

Each person is unique with individual sensitivities. Our bodies will not all react the same way to a specific medication or dosage. It usually takes a few weeks to see a remarkable improvement in your symptoms when you start thyroid hormone replacement therapy. Your doctor may need to adjust your dosing to reach a therapeutic level.

What To Do If You Think Your Thyroid Hormone Medication Isn’t Working

Consider absorption

If you find that your thyroid medication is no longer helpful, absorption may be an issue. Unfortunately, many things can affect how your small intestine absorbs your medication. To increase your intestinal absorption, take your thyroid medication on an empty stomach with water. Avoid other beverages like juice, coffee, tea, etc. Also take your thyroid medication separately from other drugs and supplements. Certain medications and supplements contain ingredients that block thyroid hormone absorption, including calcium.

Monitor your weight

Thyroid medications are often prescribed based on your weight. Therefore, even subtle changes in your weight can affect your thyroid hormone levels. If you lose or gain weight, track your weight and symptoms so your doctor can adjust your dose accordingly.

Stay consistent with the brand and type of medication

There are subtle differences between thyroid medication brands. For example, there may be different fillers, coatings, preservatives, and coloring agents that may create inconsistencies. If you switch brands, check your thyroid levels every 4-6 weeks until they stabilize.

Practice patience and test regularly

Whats The Difference Between Hypothyroidism And Hyperthyroidism

In hypothyroidism, the thyroid doesnt make enough thyroid hormone.

The difference between hypothyroidism and hyperthyroidism is quantity. In hypothyroidism, the thyroid makes very little thyroid hormone. On the flip side, someone with hyperthyroidism has a thyroid that makes too much thyroid hormone. Hyperthyroidism involves higher levels of thyroid hormones, which makes your metabolism speed up. If you have hypothyroidism, your metabolism slows down.

Many things are the opposite between these two conditions. If you have hypothyroidism, you may have a difficult time dealing with the cold. If you have hyperthyroidism, you may not handle the heat. They are opposite extremes of thyroid function. Ideally, you should be in the middle. Treatments for both of these conditions work to get your thyroid function as close to that middle ground as possible.

Hyperthyroidism & Thyroid Storm Signs & Symptoms (& Why They Occur)

Many supplements claim to support thyroid healthbut some are laced with thyroid hormones not listed on the label. Adding them to your medication could mean youre getting too much.

In a 2013 study of 10 top-selling thyroid-support products sold on the internet, researchers from Germanys Landstuhl Regional Medical Center and from the Walter Reed Army National Military Medical Center in Bethesda, MD, found that nine were laced with T3, T4, or both in a variety of amounts. Ingredient labels listed animal thyroid tissue for some while others only listed herbs such as ashwagandha, guggul, and Coleus forskohlii. The researchers concluded that drugs were added to the supplements. ¹²

Supplements, including types containing a seaweed called kelp, may also contain dangerously high levels of iodine. And natural thyroid supplements may contain gland tissue from the thyroid, liver, heart, pancreas and other animal organsraising a small but serious risk for exposure to prions, which are agents that could transmit the brain disease CreutzfeldtJakob. ¹³

Talk With Your Doctor About Testing

You can develop hypothyroidism while pregnant. Some doctors routinely check thyroid levels during pregnancy to monitor for low thyroid hormone levels. If your levels are lower than they should be, your doctor may suggest treatment.

Some people who never had thyroid problems before they were pregnant may develop them after having a baby. This is called postpartum thyroiditis.

In many cases, the condition resolves within 12 to 18 months, and medication is no longer required. However, around 20 percent of people with postpartum thyroiditis will need long-term therapy.

Your Menstrual Cycle Is Unusual

Many women with hypothyroidism experience unpredictable menstrual cycles and other menstrual problems. Irregular periods, heavy bleeding and missed cycles are all connected to having too little of the thyroid hormones circulating.

Many women find, when they settle on the correct dose of thyroid medication, that their menstrual cycle becomes more regular and manageable. If you have started experiencing menstrual cycle irregularity or problems once more, this could be a sign that your thyroid medication needs checking.

Symptoms Of An Underactive Thyroid

Many symptoms of an underactive thyroid are the same as those of other conditions, so it can easily be confused for something else.

Symptoms usually develop slowly and you may not realise you have a medical problem for several years.

Common symptoms include:

Elderly people with an underactive thyroid may develop memory problems and depression. Children may experience slower growth and development. Teenagers may start puberty earlier than normal.

If you have any of these symptoms, see a GP and ask to be tested for an underactive thyroid.

Signs That Your Thyroid Medication Is Not Working


If you are on thyroid medication for an underactive thyroid, it is routine procedure to have your blood work done every 2-3 months to monitor your thyroid hormone levels. Most practitioners will measure TSH and T4. TSH is a pituitary hormone that signals the thyroid to increase production of both T4 and T3. Thyroid medication such as Synthroid is a synthetic version of T4 . When T4 is administered, TSH level decrease. This is what leads to your labs appearing normal. Unfortunately, this is not where the tale of thyroid hormone ends. This article will discuss some important concepts with respect to thyroid hormone conversion.

A healthy thyroid mostly makes T4. In fact, the thyroid makes 90-95% T4 and 5-10% T3. T3 is the metabolically active thyroid hormone. It has a much shorter half life and is used up within a few hours. T4, on the other hand, has to be converted into T3 in the liver, kidneys, and by the gut bacteria. One iodine molecule is removed from T4 to convert it into T3. The enzyme requires both zinc and selenium to function optimally. Zinc is one of the most common nutrient depletions we see clinically in thyroid patients. In fact, taking thyroid medication , can further deplete both zinc and selenium levels since it calls for increased activity of the converting enzyme .

Your doctor swears everything is fine and life goes on. Sadly, many women trust that everything is okay and this is as good as it gets. This could not be further from the truth.

How To Adjust Or Make Changes To Your Thyroid Medication

What if you have waited the appropriate amount of time but are still feeling poorly?

Its time to make some changes to your thyroid medication.

In order to do this, you need to follow two steps:

#1. Get your thyroid tested

#2. Make changes to your thyroid medication

Why do you need to get your thyroid tested first?

Because you need to see how well your previous dose of thyroid medication was working.

You should have a baseline set of labs that you received in which you were diagnosed with a thyroid condition.

When you re-test your thyroid you can compare your new set of labs to the old one.

Did your TSH go down? If you are taking thyroid medication you should see it drop .

Did your free T3 increase? If you are taking the right type of thyroid medication you should see your free T3 increase.

Did your free T4 increase? If you are taking levothyroxine then you should see your free T4 increase.

After comparing your old lab tests to your new ones, you should be able to see if your thyroid medication was working and how well it was working.

If all of your lab tests are going in the wrong direction then you know you need to make dramatic changes .

Alternatively, if your lab tests are trending in the right direction but just not quite there yet then you know you just need to make some small changes to your medication .

There is no one size fits all pattern that you can apply when it comes to your thyroid which makes getting these lab tests all the more important.
