Weight Gain After Hyperthyroidism Treatment Is Common: What To Know

*Thyroid Weight Gain Symptoms* Do I have a Thyroid Problem?

With Kristien Boelaert, MD, PhD, and Reshmi Srinath, MD

After successful treatment for her overactive thyroid , the patient , not only gained all excess the weight she had lost while her thyroid gland was in overdrive, but the weight continued to creep up.

This is common complaint repeated by many people who visit the discussion board on EndocrineWeb. Understandably, June was so distraught with the undesirable weight gain, so she stopped taking the medication meant to normalize her thyroid levels.

Lifestyle Factors Associated With Improvements In Thyroid Function

Lifestyle factors have a considerable impact on the function of the Thyroid gland. When unhealthy lifestyle factors and habits are adopted, Thyroid function can be adversely impacted. These may cause the Thyroid to develop an excess amount of Thyroid hormones, or lead to the Thyroids activity becoming impaired thus causing an insufficient amount of Thyroid hormones being produced in a patients body.

A healthy lifestyle can contribute to a healthy Thyroid gland. Adopting a healthy diet, which should ideally include an adequate supply of antioxidants, as well as vitamins and minerals, will aid in maintaining optimal Thyroid function.

In addition to dietary habits, it is essential to understand that physical exercise is also essential for a healthy endocrine system, including a Thyroid gland that produced an adequate supply of Thyroid hormones. Avoiding smoking and too much alcohol can also be beneficial for improving Thyroid function and avoiding dysfunctions that may adversely affect the Thyroid gland.

What Do Our Parathyroid Patients Say About Weight Gain After Parathyroid Surgery

Weight loss is actually more common after parathyroid surgery than weight gain. Remember that the number one symptom of hyperparathyroidism is fatigue. People with a high calcium and/or PTH often complain that they are tired all the time. Or that after about noon every day they just want to take a nap, but the nap doesnt help them feel better. Our patients say they are tired of being tired. This chronic fatigue means that people are less active. They arent outside working in the yard. They tend to spend more time on the couch than they used to. And most gain some weight, as noted in the scientific literature discussed above.

Can Hyperthyroidism Be Cured

Yes, there is a permanent treatment for hyperthyroidism. Removing your thyroid through surgery will cure hyperthyroidism. However, once the thyroid is removed, you will need to take thyroid hormone replacement medications for the rest of your life. Your body still needs thyroid hormones, just not at such high levels as you have in hyperthyroidism. Though you will need to regularly take the medication and check in with your healthcare provider regularly, this is a manageable form of thyroid disease which allows you to live a normal life.

Conventional Treatment Approaches To Addressing These Thyroid Gland Disorders

Thyroid Disorders

Pharmaceutical treatment options are available to assist with the treatment of both Hypothyroidism and Hyperthyroidism. The particular treatment option administered to a patient depends on the particular Thyroid disorder they are suffering from, as well as the severity of their condition. Additional factors may also be taken into account, such as gender, age and weight.

Thyroid Hormone Production And Regulation

The thyroid gland produces the hormonesthyroxine, triiodothyronine, and calcitonin. Thyroid hormones thyroxine and triiodothyronine are produced by thyroid folliclar cells. Thyroid cells absorb iodine from certain foods and combine the iodine with tyrosine, an amino acid, to make thyroxine and triiodothyronine . The hormone T4 has four atoms of iodine, while T3 has three atoms of iodine. T4 and T3 regulate metabolism, growth, heart rate, body temperature, and affect protein synthesis. The hormone calcitonin is produced by thyroid parafollicular cells. Calcitonin helps to regulate calcium concentrations by lowering blood calcium levels when the levels are high.

Other Causes Of Hyperthyroidism

Hyperthyroidism can also result from thyroid nodules. These are lumps that develop inside the thyroid and sometimes begin producing thyroid hormones. Large lumps may create a noticeable goiter. Smaller lumps can be detected with ultrasound. A thyroid uptake and scan can tell if the lump is producing too much thyroid hormone.

The Role Of Thyroid Hormones

Does Levothyroxine Cause Weight Gain? What to do if it is slowing down your metabolism

Thyroid hormones heavily influence your metabolism, your body temperature, and your appetite regulation. Your thyroid works closely with your hypothalamus, a small area of your brain, to maintain both your weight and your energy balancewhat’s left after you eat and your body uses the calories it needs.

How this happens exactly isn’t clear, but one thing is certain: It isn’t thyroid hormones alone that play a role in how much energy your body uses. Thyroid hormones work along with a number of other hormones, proteins, nuclear receptors, and chemicals too, which is why it’s such a complicated process.

Can Hyperparathyroidism Make You Gain Weight

Weight gain is a very common point of concern for several patients suffering from hyperparathyroidism and other hormonal troubles. Furthermore, surgery for hyperparathyroidism is also known to cause weight issues in some cases. Hyperparathyroidism and weight gain has a better scientific link than just being myths.

Its been known for over decades that there is a significant link amongst hyperparathyroidism and weight gain1. The tumors of parathyroid gland are known to trigger weight gain in the patients. Several types of research have pointed out the presence of weight gain and tumor linkage. In fact, several medical journals have published several scientific studies depicting thousands of patients affected by weight issues caused by parathyroid tumors2.

How Long Does It Take To Treat Hyperthyroidism

The amount of time it takes to treat hyperthyroidism can change depending on what caused the condition. If your healthcare provider treats your condition with anti-thyroid medications your hormone levels should drop to a controllable level in about six to 12 weeks. Your healthcare provider may decide to give you high doses of iodine drops which would normalize thyroid levels in seven to 10 days. However, this is short-term solution and you will most likely need a more permanent solution like surgery. Though you may need to wait for a period of time to be scheduled for thyroid surgery , this is a very effective and definitive way to treat hyperthyroidism. Its considered a permanent solution for hyperthyroidism.

The More Medication Myth

You may have heard that thyroid hormones can be used to lose weight, even in people without thyroid disease. While synthetic thyroid hormones have been used this way in the past, research has shown that most people gain all the weight back once they stop using them. Worse, being on thyroid hormones unnecessarily can result in serious side effects.

For people who are already using levothyroxine, increasing the dose above whats needed can lead to more weight loss, but its usually not significant and those pounds are often gained back once the dose is decreased again. This is also an unhealthy way to lose weight as an increased dose is also associated with adverse reactions, including heart issues, insomnia, headaches, menstrual irregularities and skin rash.

Treating Hyperthyroidism To Help With Weight Loss

If you have your thyroid then you should focus on reducing thyroid antibodies that cause hyperthyroidism.

You can actually check for these antibodies with the TSI serum test.

This test evaluates for thyroid stimulating immunoglobulins and it is these guys that basically sit on your thyroid hormone and cause it to pump out excessive amounts of thyroid hormone.

But the good news is that you might be able to reduce these antibodies with some targeted therapies.

This will go a long way to reducing the amount of thyroid hormone you are producing naturally and may help you to reduce your medication.

If you can reduce your antithyroid medication down to half of what it was, or even go off of it completely, then you will dramatically improve your metabolism.

How to reduce TSI antibodies:

You can find a list of supplements below that can improve thyroid function and improve immune function in those with hyperthyroidism:

Weight loss after Thyroidectomy & RAI ablation therapy:

If you’ve already had your thyroid taken out or you’ve had radioactive iodine ablation, then you are going to be reliant upon thyroid medication.

And let me be clear:

If you’ve had your thyroid taken out you are no longer hyperthyroid, you are now HYPOthyroid.


Because your body can no longer produce thyroid hormone on its own – you now need to supplement with thyroid hormone replacement.

Patients who have had their thyroid removed or who have undergone RAI almost ALWAYS gain weight but sometimes even more.

Can Weight Gain Contribute To Hyperparathyroidism

People dealing with hyperparathyroidism often display no visible symptoms. However, hyperparathyroidism has been linked to increased risk of a variety of medical conditions, including:

  • Hypertension: Occurs due to high blood pressure that forces an excess amount of blood to push against artery walls people dealing with hypertension generally have blood pressure above 130/80.
  • Insulin Resistance: Occurs when cells in the muscles, body fat, and liver resist or ignore hormone insulin signals when this happens, the body cannot get glucose, its main source of fuel, from these cells and put it into the bloodstream.
  • Dyslipidemia: Occurs when the bodys blood lipid levels are too high or low lipids provide energy to cells, and people dealing with lipid levels that are higher or lower than normal risk atherosclerosis, a medical condition that makes it difficult for blood to flow throughout the body.

A person who is overweight may be more prone than others to the aforementioned medical conditions. As such, this individual is more susceptible than others to primary hyperthyroidism and its associated symptoms.

Comparatively, in a study published by Medical Hypotheses, researchers found that body weight was elevated in elderly patients dealing with primary and secondary hyperparathyroidism. They also discovered that insulin resistance was a common complication associated with both forms of hyperparathyroidism.

When To See A Doctor

In most cases, weight gain with hyperthyroidism is probably nothing to worry about, especially if you previously lost a lot of weight due to your initially untreated condition. However, if youre gaining a lot of weight or have other uncomfortable symptoms, it might indicate a new problem. Talk to your doctor about finding the right course of treatment for you.

Weight gain alone is generally not a sign of a thyroid problem. But weight gain alongside the following symptoms can indicate hypothyroidism:

Why And How Does Mitochondrial Destruction Happen

Soy Harms the Thyroid and Can Cause Weight Gain

Mitochondria as we discussed before is your energy power house.

It consumes fuel and converts into energy to power our whole body. Now mitochondria are very efficient machine and it can consume glucose or fatty acids and break them down to produce energy in the form of ATP.

During this energy production process, there are some waste products that are also formed which are called Reaction oxygen species .

In people with thyroid dysfunction, this mitochondrial machinery starts to break down and which causes metabolic dysfunction. This metabolic dysfunction is the reason people start to gain weight.

Now let us understand why does mitochondrial destruction happen.

So the underlying process that causes destruction of mitochondria is inflammation.

The inflammation inside our body causes mitochondrial destruction. It is well known now in the medical community that patients with a thyroid disorder have a high level of inflammation markers present.

So this underlying inflammation first destroys your mitochondria and then destroys your thyroid gland.

Destruction of the thyroid gland further slows down the mitochondria. So you see its a vicious cycle which forms and makes it very challenging for people to lose weight.

Why Do Some People With Hyperthyroidism Experience Weight Gain

For many people with hyperthyroidism and Graves Disease, extreme weight loss is an issue. In fact, when I dealt with Graves Disease I lost over 40 pounds, and I had a difficult time gaining weight. Its a similar situation for many of my hyperthyroid patients, and the reason for this is due to the elevated thyroid hormone levels. However, some people with hyperthyroidism and Graves Disease have difficulty losing weight. In other words, weight gain is an issue for some hyperthyroid patients. And in this article Im going to discuss some of the most common reasons why this is the case.

So lets go ahead and discuss ten reasons why some people with hyperthyroidism and Graves Disease might experience weight gain and have difficulty losing weight:

1. Taking antithyroid medication. The most common reason why some people with hyperthyroid conditions gain weight is because they are taking antithyroid medication. This includes Methimazole , Carbimazole, and PTU. And the reason for this is because taking antithyroid medication will decrease thyroid hormone levels, which in turn will slow down the metabolism, and thus contribute to gaining weight.

As I briefly mentioned earlier when talking about xenohormones, you wont be able to completely avoid these environmental toxins. And so the next best thing is to minimize your exposure to them, and to also do things to eliminate them from your body, which Ill talk about shortly.

How To Overcome Weight Gain

Losing Weight With An Underactive Thyroid

Hypothyroidism slows down your metabolism, making it more difficult to lose extra pounds and maintain a healthy body weight. But weight loss is still possible with hypothyroidism.

Hypothyroidism is a condition in which the thyroid gland, which produces hormones that regulate a number of body processes, becomes underactive and doesnât produce enough thyroid hormone to allow the body to function properly. One of the key processes these hormones help to regulate is metabolism that magic word we all know due to its connection to diet and weight-loss. It seems like everyone is trying to speed up their metabolism with the right mix of foods and exercise to help shed pounds. So when your body is working against you and slowing your metabolism down even more, weight loss becomes an even bigger challenge.

What Is A Thyroid Disorder

Thyroid disorder is experienced when the gland is either overactive or underactive, and it is not able to perform its basic functions aptly. Several health issues can crop up when the thyroid gland starts to dysfunction and release too little or too much of those hormones. While the former is called hypothyroidism, the latter is referred to as hyperthyroidism. Out of these two, the former is more commonly prevalent and, for some reason, affects females way more than men. In fact, statistics suggest that women, especially those in their 20s and 30s, are ten times more likely to experience thyroid gland dysfunction. The likelihood as well as the severity, of course, increases as they age.
