Thyroid Hormone And Weight Gain

The Role Of Metabolism

Hormonal Imbalance That Cause Weight Gain | PCOD, PCOS, THYROID, DIABETES

Your metabolism involves a series of processes that break down food and convert it into the energy your body needs to run. It also determines how quickly your body uses calories. Some of how efficiently your metabolism runs is determined by genetics.

You burn calories through physical activity and by performing your daily activities. Your body also uses energy when youre resting. The efficiency at which it does this is called your basal metabolic rate . Whenever you have excess energythe result of eating more food than your body can usethis energy gets stored in fat cells and you gain weight.

How Thyroid Function Can Affect Your Weight

Thyroid hormone helps regulate your metabolism. Your metabolism is how much energy your body uses and at what rate. This means that thyroid hormone also affects your basal metabolic rate. This is how much energy your body uses to keep functioning while its at rest.

In most cases, excess thyroid hormone is associated with a high basal metabolic weight. This means that your body burns more energy while its at rest, so weight loss is a common symptom of hyperthyroidism.

This also means that not producing enough thyroid hormone is usually associated with a low basal metabolic rate. Therefore, hypothyroidism can cause weight gain. Your body isnt burning as much energy, which can lead to a calorie surplus.

But your metabolism is affected by a lot more than just thyroid hormone. Other hormones, how much and what you eat, your physical activity, and many other factors play a role. This means that thyroid hormone levels arent the whole story when it comes to losing or gaining weight from thyroid conditions.

Some people with hyperthyroidism might experience weight gain instead of the more common weight loss. Some reasons why that might happen include:

Does Thyroid Cause Weight Gain

An unexplained change in weight is one of the most common signs of a thyroid disorder. Weight gain may signal low levels of thyroid hormones, a condition called hypothyroidism. In contrast, if the thyroid produces more hormones than the body needs, you may lose weight unexpectedly.

Weight Gain And Hormone Imbalances On Your Body

One of the easiest to assess for hormone imbalances is by assessing the distribution of fat on your body.

It turns out that many hormonal conditions result in a change in body fat distribution on the body and may help identify your hormone imbalance.

This should be used in conjunction with lab testing whenever possible, but this does serve to help guide some patients in the event that their doctor isn’t willing to order the more advanced tests like leptin, insulin, reverse T3, etc.

With that in mind you can use this list to compare your body fat distribution to various hormone imbalances:

  • Abdominal belly fat – Insulin resistance + Cortisol issues
  • Weight gain in butt/thighs/hips – Low progesterone and/or high estrogen levels
  • Weight all over + ravenous appetite – Thyroid resistance and/or leptin resistance
  • Weight gain in upper arms + reduced muscle mass – Low testosterone

While this list isn’t always 100% accurate, it can definitely help guide you.

I realize that many readers of my blog live in different countries where some of the therapies I recommend aren’t even available.

In this case, it may be useful to evaluate your body using the distribution of your body fat and then trialing treatment from there.

Hypothyroidism : A condition in which the thyroid gland doesn

Thyroid cancer diagnoses have increased from 17,000 in 2002 to 57,000 in 2012. Even so, it’s still relatively uncommon and has a high survival rate 97 percent after five years, says Jose C. Dutra, M.D., director of the thyroid surgical clinic at Northwestern University’s Feinberg School of Medicine.

Dutra and other experts believe that the spike in diagnoses is due to the wider use of MRI and CT scans, which can detect tiny lumps that can’t be touched. “Ninety percent of all enlargements are not cancerous,” he says.

Finally, about six months ago, one of her doctors heard about a new type of thyroid drug and sent Kruger to Mark Lupo, M.D., a thyroid specialist in Sarasota. He prescribed Tirosint, a liquid gel cap form of levothyroxine sodium, the thyroid hormone replacement pill commonly used to treat hypothyroidism.

Although drugs can work differently in each individual, Tirosint’s liquid form seemed to do the trick for Kruger: She dropped 20 pounds in six months. “And when I get up in the morning, I don’t feel like someone has beat me with a stick,” she says. More importantly, her heart problems have improved.

How Is Hormonal Weight Gain Diagnosed

An evaluation with an endocrinologist can help determine if a hormonal condition is the underlying cause of weight gain. Declining estrogen, adrenal disorders, hormonal resistance, thyroid imbalance, and several other hormonal imbalances can lead to weight gain. Laboratory tests give endocrinologists insight to hormonal imbalances when combined with your symptoms and presentation, but it doesnt always tell the whole story. Blood and urine results can be influenced by many things. For this reason, we suggest special evaluations to see how metabolic information relates to the lab data.

Relationships Between Thyroid Hormones Body Weight And Other Assessments At Baseline

The baseline characteristics of the participants according to tertiles of thyroid hormones are shown in Table 1. At baseline, there were significant inter-correlations between free T3, free T4, total T3, and total T4 . TSH was weakly associated with free T4 and total T4 , and not associated with free T3 and total T3 . After adjusting for age, sex, and race, free T3 and total T3 were positively associated with body weight, BMI, and RMR at baseline, whereas free T4 had weak, inverse correlations with body weight, BMI, and RMR . Total T4 and TSH were not correlated with these measurements . In addition, free T3, total T3, and free T3/free T4 ratio were positively associated with body weight, WC, blood pressure, leptin, insulin, and triglycerides . Free T4 had weak, inverse associations with whole body lean mass, glucose, leptin, and insulin . In contrast, total T4 and TSH were not significantly associated with most of these parameters .

Leptin & Ghrelin: What Do They Do

Leptin and ghrelin work to control our appetite and the amount of food we eat. Leptin is a satiety hormone. In other words, this hormone is responsible for telling us that we’re full and we’ve had enough to eat. Leptin is made in the fat cells of the body. Ghrelin, on the other hand, is responsible for stimulating appetite and making us feel hungry. Ghrelin is made mostly in the lining of the stomach and the wall of the small intestines.

What can you do to manage healthy leptin & ghrelin levels?

Getting The Right Diagnosis

Do Thyroid problems cause weight gain? – Dr. Karthik Prabhakar

Hypothyroidism is more likely to develop in women, and a personal history or family history of thyroid issues can increase your risk. To accurately test for hypothyroidism, a blood test for thyroid stimulating hormone is used. Even small changes in your thyroid hormone levels will cause very big changes in TSH secretion. The TSH test is really accurate and is the appropriate test for 99 percent of cases. Other lab tests for thyroid function are supplemental, and may not be clinically relevant or appropriate, adds Dr. Bloomgarden.

Once a diagnosis is confirmed, your physician will work with you to find the appropriate treatment. The most frequently used treatment for hypothyroidism is replacing the hormone with a substitute, known as levothyroxine . This is a precursor to the active hormone and seeks to replicate the hormones your body is failing to produce properly. Your body does not care if you make or take thyroid hormone, adds Dr Bloomgarden.

Causes of hypothyroidism can include:

Symptoms of an underactive thyroid can be nonspecific or reflect other issues. You may experience:

  • Fatigue
  • Dry skin

Are There Preventative Steps Or Measures To Avoid Hormonal Weight Gain

Seeking early evaluation with an endocrinologist so the appropriate interventions can be started sooner will help with minimizing and possibly reversing hormonal weight gain. Additionally, improving dietary choices, increasing physical activity, getting more sleep, managing stress levels effectively, quitting smoking, and limiting alcohol are all ways to decrease and avoid hormonal weight gain.

The Connection Between Thyroid Function And Weight Gain

Home The connection between thyroid function and weight gain

The inability tolose weight from diet and exercise alone can be extremely frustrating. Thereare many factors that affect weight management, and for those who struggle withthis it may be worth investigating other causes of this stubborn metabolism. Onesuch cause is the functioning of the thyroid gland and its respective hormones.Thyroid hormones play crucial roles in how the body uses energy and regulatesappetite. Additionally, fat cells, also called adipose tissue, contains theirown messengers and hormones that affect energy stores and usage. The interactionbetween these cells, their messengers and thyroid hormones are major factorsthat contribute to weight management.

Thyroid hormonesact directly and indirectly on metabolic cycles. As such, they help decide howand when cellular energy is used. Because of this relationship, its beentheorized that there is a direct relationship between obesity and thyroid function.An overactive thyroid, hyperthyroidism,often results in weight loss, whereas an under-functioning thyroid and lowlevels of thyroid hormone ,can lead to weight gain and/or an inability to lose weight.

Thyroid Problems And Weight Gain

Thyroid or Hyperthyroidism is a condition in which our thyroid gland is unable to produce enough hormones for the body. Early in life, you may not notice enough symptoms of this disease but as you move on you may face a lot of health-related issues like obesity, infertility, and joint pain.

Today we will dig deeper into the relationship between thyroid and weight gain. We know it is a crucial subject, and almost all people who deal with hyperthyroidism face rapid weight gain.

If you are someone who is gaining rapid weight and is having difficulty in losing it then you should definitely visit your doctor and get yourself tested for thyroid. Hyperthyroidism can be brought back to its lower levels but can never be treated completely so make sure you stay with us till the end to find out all the solutions to your problem.

Thyroid Hormone As A Potential Treatment For Obesity


Weight loss up to 5â10% of the initial weight reduces the risk factors of cardiovascular disease, prevents the development of type 2 diabetes, and improves other health outcomes in obese patients. Unfortunately, bariatric surgery is at present the only effective method to rapidly induce weight loss in morbid obese patients .

Despite the effect of T3 on heat generation, the hypothesis that T3 administration might lead to a negative energy balance and to a consequent reduction of lipid storage is questionable for several reasons. The greater REE produced by T3 administration can be counterbalanced by a simultaneous stimulation of appetite, which in turn results in increased energy intake. Moreover, the increased lipolysis induced by T3 is associated with the induction of lipogenesis.

What About Thyroid Cancer

Thyroid cancer is uncommon and is among the least deadly. The main symptom is a lump or swelling in the neck, and only about 5% of thyroid nodules turn out to be cancerous. When thyroid cancer is diagnosed, it is most often treated with surgery followed by radioactive iodine therapy or, in some cases, external radiation therapy.

Can Imbalanced Thyroid Lead To Weight Gain

Thyroid is a small, butterfly shaped gland that is present at the bottom front of our neck, just below the Adams apple. This two-inch long gland forms an important part of the endocrine system. By using up iodine from our diet, the gland goes on to manufacture two main hormones called triiodothyronine and thyroxine , and secretes them into the bloodstream. These hormones help in regulating metabolism, pave way for general growth and development, and allow our body to perform various everyday tasks.

Can An Endocrinologist Help With Weight Loss

An endocrinologist can very often help you reverse weight gain that is associated with hormonal imbalances. Potentially useful interventions include lifestyle changes such as exercise, diet modification, or stress management, as well as treatments such as testosterone or thyroid hormone replacement. Medications may be able to help with weight gain-related symptoms such as increased appetite, or to moderate excessive hormone levels.

Hormones That Cause Weight Gain- Leptin & rT3 (Hypothyroidism)

Levothyroxine is the mainstay treatment for underactive thyroid. Its a pill that replaces the thyroid hormone the body naturally wants. We monitor patients blood levels regularly to make sure we have the right dose.

For overactive thyroid, there are also oral medications methimazole, propylthiouracil and sometimes, radioactive iodine, which is administered by a radiologist. Less often, an overactive thyroid is removed, a relatively low-risk surgery.

If you are still wearing your winter coat when it’s 60 degrees and sunny, you might be suffering from hypothyroidism. It might be easy to adjust the temperature in your house or car, but patients who have hypothyroidism struggle to regulate the temperature in their bodies. Because the thyroid gland controls your body temperature, when hypothyroidism patients’ bodies make too little thyroid hormone, body temperature tends to decrease because less energy is being burned by downstream cell targets. Less energy compounded with slow metabolism equals less heat.

Low Thyroid Causes Other Hormones That Lead To Weight Gain

The association between weight gain and hypothyroidism is somewhat complex and includes much more than just your thyroid.

The easiest way to think about this is to realize that everything in your body is connected.

You can think of this connection like a spider web.

When one string is pulled, it pulls the entire web.

Meaning you can’t really change one thing without affecting several others.

This is true of thyroid hormone as well.

As thyroid hormone levels fall it causes a chain reaction which changes multiple other hormonal systems in your body.

And guess what these systems do?

They all contribute to your weight!

Let’s walk through what happens:

High insulin levels

The connection between high insulin and weight gain has been well established.

What you probably don’t realize is that this connection extends to patients without diabetes or pre-diabetes as well.

Patients with highly elevated levels of fasting insulin still have weight gain problems.

So we know that high levels of insulin lead to weight gain, but what you probably don’t know is that thyroid hormone influences insulin resistance.

Low levels of thyroid hormone lead to the condition known as insulin resistance.

This connection is so strong that low thyroid hormone can actually lead to type II diabetes .

And here’s the bigger deal:

Replacing thyroid hormone in your body doesn’t take care of this hormone imbalance!

That means you can replace your thyroid hormone, but you will still have insulin resistance.

The Role Of Thyroid Hormones

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 balancewhats left after you eat and your body uses the calories it needs.

How this happens isnt exactly clear, but one thing is certain: It isnt 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, which is why its such a complicated process.

Thyroid And Weight Gain

Hypothyroidism symptoms: 12 signs to look out for

You know that you have been eating right, working out regularly and maintaining a healthy lifestyle. But still, there is this unexplained gain of weight. Apart from that, you have also been feeling overly tired of late for no specific reason. If the answer is yes, then you must get in touch with your physician, who will most likely recommend you a thyroid test. Unfortunately, hypothyroidism is strongly associated with weight gain. The major reason behind weight gain among hypothyroid patients is the reduced metabolism. This can lead to a gain in the weight, and the more severe the hypothyroidism, the more pounds you are likely to put on.

And while you might indulge in the healthiest of foods, but a slow rate of metabolism does not allow your body to convert that food into energy all that quickly as it should. Ultimately, if your thyroid levels are not balanced, you could not only end up gaining weight, but also feel much less energised than you should. Also, while some of the weight gain is fat, most of it is just the fluid build-up, as an under-active thyroid can significantly affect our kidney function.

You’re Having Digestive Problems

We know constipation is an embarrassing topic that no one likes to discuss, but if you can’t boot your bowel issues, it might be time to call up your primary care doctor. Without enough of the metabolism-controlling thyroid hormone, many of your body’s functions slow down. One of these functions is the action of the digestive tract, which will start to slow down. Hypothyroidism can weaken the contraction of the muscles that line your digestive tract, causing stool to move too slowly through the intestine. Your primary care doctor can refer you to us to make a definite diagnosis of your condition.
