Do Doctors Prescribe Thyroid Medication To Help With Weight Loss

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

In the past, some doctors prescribed thyroid medication to help people lose weight even if they did not have a thyroid condition. Of course, it seemed to make sense at the time: if you speed up the metabolism, you can expect to see more weight loss in less time.

However, there is a big problem with this approach to weight loss. Too much thyroid hormone also causes other symptoms in your bodyâsome of which may even cause you to gain weight.

Generally, people with excess thyroid hormone have symptoms that can hinder weight loss, such as anxiety, insomnia, a rapid heart rate, muscle weakness, and heat sensitivity. Indeed, anxiety alone can often lead to overeating or comfort eating, adding to weight gain. Thus, excess thyroid hormones or taking a larger dose of thyroid medication is unlikely to lead to dramatic weight changes.

Suppose your thyroid-stimulating hormone and T4 levels are borderline, or you have subclinical hypothyroidism. In that case, weight gain may be enough to support your doctor’s decision to prescribe medication. If this is the case, you will want to watch for signs of hyperthyroidism and be diligent in having your thyroid levels assessed per your doctor’s recommendation.

Will Hypothyroidism Make Me Gain Weight

If your hypothyroidism is not treated, you could gain weight. Once you are treating the condition, the weight should start to lower. However, you will still need to watch your calories and exercise to lose weight. Talk to your healthcare provider about weight loss and ways to develop a diet that works for you.

Thyroid Hormones: Metabolism And Functions

Thyroid hormones are essential to your metabolism. In fact, many of your bodyâs cells have thyroid hormone receptors, which means that thyroid hormones can influence your metabolism in a host of ways.

Take fat metabolism, for example. Thyroid hormones help your body burn fat â providing you with more energy. As a result of this effect on fat metabolism, thyroid hormones bump up your basal metabolic rate â which means youâll be burning off fat even when youâre not physically active.

Thyroid hormones also impact carbohydrate metabolism. For instance, thyroid hormones stimulate the production of glucose . Your brain runs on glucose as its energy source, so if it werenât for your thyroid hormones, your brain couldnât function. The result would be a bit like unplugging your computer from its power source â or taking out its battery!

Whatâs more, thyroid hormones also control your bodyâs internal temperature, protecting your organs from frosty temperature in the winter or boiling-hot conditions during the summer. In women, thyroid hormones help maintain a regular menstrual cycle â just one more example of the large number of ways thyroid hormones regulate so many aspects of your body.

In short, to feel energized and be healthy, you need optimal thyroid levels. But thereâs a catch: you have to have the right amounts of thyroid hormones. When your body doesnât have the right levels of thyroid hormones, your health falters.

What Can I Do If I Cant Seem To Lose Weight

Tried all of the above, and still cant seem to lose weight?

First, make sure your medication and thyroid levels are optimal. Your thyroid levels can change over time, and you may need to see your healthcare provider for a repeat blood check to make sure your medication is at a high enough dose.

You should also make sure you arent taking in too many calories. Keeping track of your calories and what you eat in a food diary has shown to help people lose weight. There are many calorie tracking apps such as MyFitnessPal, Cronometer, and LoseIt that can make this really easy.

And finally, if the scale doesnt seem to be budging, it may be worth checking in with a nutritionist to look at your overall diet and come up with the best plan for you.

Low Thyroid Hormone Levels

10 Signs and Symptoms that You Have an Underactive Thyroid ...

Iodine â frequently found in seawater and seafood â is essential to human health. And if youâre not getting enough iodine in your diet, then you may be putting your health through the gauntlet of hypothyroidism. Hypothyroidism refers to an underactive thyroid â your thyroid gland doesnât produce enough thyroid hormones. Iodine deficiency may result in hypothyroidism TSH levels , but this is not the only possible cause of low thyroid hormone levels. For example, autoimmune disorders â as well as exposure to radiation therapy during cancer treatment â can also lead to hypothyroidism.

Symptoms of low thyroid hormone levels range from the dramatic to the somewhat more subtle. People with hypothyroidism might gain weight rapidly, for example â or find themselves wearily running on fumes all day due to excessive fatigue. Hair loss can also result â and you may be less resistant to cold temperatures. Your skin can also have a cool and dry feel to it. In women, irregular â or even completely absent â menses is another sign of low thyroid hormone levels.

Thyroid Hormone And Brown Adipose Tissue In Energy Homoeostasis

Thermogenically active brown adipose tissue is found in adults. Hence, the presence of thermogenically active D2 BAT in an adult is clinically important. In the recent years, the presence of BAT has been recognized as an important target for treating obesity. The energy homeostasis in the BAT has been found to be affected by a great extent by thyroid hormone signaling. Thyroid hormone signaling, particularly by inducing type II deiodinases, has a cardinal function in brown tissue adipogenesis. The BAT gets activated by local D2 mediated action. D2 increases expression of the gene Ppargc1a by enhancing thyroid hormone signaling, which coactivates thyroid hormone receptors, leading to increased expression of the gene Ucp1. Dio2 is also upregulated by increased T3 signaling. These D2-dependent pathways provide the mature brown adipocyte with its full thermogenic identity. D2 dependent T3 is necessary for BAT to be functional and also for brown adipogenesis as demonstrated by preclinical trials and cell line studies. Thereby, activation of BAT in adults, specifically through thyroid hormone-mediated pathways, has a potential role in treating obesity.

What Is The Relationship Between Hyperthyroidism And Weight

Since the BMR in patients with hyperthyroidism is elevated, many patients with an overactive thyroid do, indeed, have some weight loss. Furthermore, weight loss is related to the severity of the overactive thyroid. For example, if the thyroid is extremely overactive, the individuals BMR increases which leads to increased calories needed to maintain the body weight. If the person does not increase the amount of calories eaten to match the excess calories burned, then there will be weight loss. As indicated earlier, the factors that control our appetite, metabolism, and activity are very complex and thyroid hormone is only one factor in this complex system. Nevertheless, on average the more severe the hyperthyroidism, the greater the weight loss observed. Weight loss is also observed in other conditions where thyroid hormones are elevated, such as in the toxic phase of thyroiditis or if the dose of thyroid hormone pills is too high for a patient. Since hyperthyroidism also increases appetite, some patients may not lose weight, and some may actually gain weight, depending on how much they increase their caloric intake.

How Does Hypothyroidism Affect Weight

We dont know exactly how low thyroid levels cause weight gain, but there are probably several contributing factors.

Your thyroid helps control your metabolism and regulate your appetite. Thyroid hormones interact with many of your tissues, including your brain, fat cells, muscle, liver, and pancreas. When thyroid levels are low, your metabolism slows down and you burn less energy, even when youre resting. You are also less likely to burn fat for energy, which can cause weight gain.

Additionally, about 40% of people with an underactive thyroid feel more tired than normal. This may lead to less physical activity, which can contribute to weight gain.

Your thyroid gland weighs less than an ounce, yet has the power to affect weight gain by an average of 20 to 30 pounds if its not working properly.

Your thyroid is a small gland in the front of your neck just below your Adams apple. When its working as it should, your thyroid releases hormones that play a huge role in how your body uses energy, and in how your organs function. Because your thyroid controls your metabolism it can also have an effect on your weight.

The thyroids function is to regulate the metabolism of the body how fast or slow things go, says Kimberly Bethel, MD, of Trotwood Physician Center. It affects everything from the top of the head all the way down to the toes. And we know it affects a persons weight. If you are a fast metabolizer you will burn more calories, or if you are a slow metabolizer, youre going to gain weight.

Thyroid function is often the first thing a physician checks when a patient is experiencing unexplained weight gain or loss, because improper hormone production affects so much more than a persons size. Thankfully, the disease is treatable, although not curable.

What Is The Relationship Between Hypothyroidism And Weight Gain

Since the BMR in the patient with hypothyroidism is decreased, an underactive thyroid is generally associated with some weight gain. The weight gain is often greater in those individuals with more severe hypothyroidism. However, the decrease in BMR due to hypothyroidism is usually much less dramatic than the marked increase seen in hyperthyroidism, leading to more modest alterations in weight due to the underactive thyroid. The cause of the weight gain in hypothyroid individuals is also complex, and may not be related to excess fat accumulation. Most of the extra weight gained in hypothyroid individuals is due to excess accumulation of salt and water. Massive weight gain is rarely associated with hypothyroidism. In general, 5-10 pounds of body weight may be attributable to the thyroid, depending on the severity of the hypothyroidism. Finally, if weight gain is the only symptom of hypothyroidism that is present, it is less likely that the weight gain is solely due to the thyroid.

Associated Symptoms Of Thyroid Gland Disorders

A study6 conducted by the Mansoura University Hospitals in Egypt found that dysfunctions affecting the Thyroid gland can manifest symptoms quite similar to those found in menopause.

For this reason, it is vital for medical experts to look at the Thyroid gland as a possible contributing factors to symptoms when a woman is going through menopause, and not to immediately prescribe her estrogen replacement therapy medication as a solution to her symptoms.

The study was conducted among a group of 360 women. The study found that 11.1% of the women suffered from Thyroid disorders and the administration of appropriate treatment to assist with regulating Thyroid function yielded positive results in regards to their symptoms.

Determining associated symptoms of Thyroid gland disorders, and looking for these particular symptoms when hot flashes are experienced, will help the treatment options provided to a patient suffering from hot flashes be more appropriate and work faster.
