Thyroid Hormone Effects On Diabetes

Type 1 Diabetes: Low Blood Sugar At School

The effect on carbohydrate metabolism can potentially lead to disruptionsin diabetes control. Although the glucose level does not always change, therecan be an abnormal response to glucose tolerance testing in hyperthyroidismbecause glucose rises faster thannormal.Additionally, excessive thyroid hormones increase the rate of digestive tractabsorption and thyroid hormone levels and therefore increase insulinresistance and insulin degradation.

In hyperthyroidism, glycogen synthesis and degradation increase, leading todecreased glycogenlevels. Glucoseabsorption is increased, as well as utilization and production. Peripheraltissues have increased rates of glucose uptake that can lead to theaforementioned exaggerated glucose peak during a timed glucose test. Insulinrequirements are increased, and, if not addressed adequately, control candecompensate, leading to diabetic ketoacidosis. Additionally, in patients withundetected diabetes, hyperthyroidism can unmask diabetes because glucoselevels can be abnormally elevated because of increased insulinresistance.Increased dosages of diabetes medications may be necessary in those alreadytreated, until thyroid function is stabilized and resultant glucosestabilization occurs.

What About Thyroid & Low Blood Sugar

Although low blood sugar is most common in people who are on insulin or oral diabetes drugs that increase insulin output, thyroid problems, especially hypothyroidism, can also trigger episodes of low blood sugar.

Just as an overactive thyroid hastens insulin clearance, an underactive gland may slow its breakdown, allowing insulin to remain active for longer and causing blood sugar to fall below normal levels. Reduced thyroid hormone production also slows glucose synthesis in the liver, gastric emptying, and intestinal absorption of sugar into the bloodstream.


The result? Hypoglycemia, which can make you feel jittery, irritable, and ravenous for sugar and other fast-burning carbohydrates.

How To Determine Thyroid And Low Blood Sugar Problems

If you have thyroid and low blood sugar concerns, theres a good chance you may be diagnosed with hypothyroidism. But diabetics who also have hyperthyroidism may have lower levels, too. The truth is, there is only one way to figure out if your blood glucose levels are being negatively impacted by thyroid dysfunction: a blood test.

, which makes it a good time to dive a little deeper into the topic of thyroid disease. Lets take a look at what a blood test;will tell you and how it can pinpoint a link between your thyroid and low blood sugar.

Diabetes And Thyroid Disease

Thyroid disease is common in the general population, but it is especially common in type 1 women with more than 20% having the disease. Many people with type 2, in particular middle-aged women, are also susceptible to a non-immune-based form of thyroid disease.


The thyroid, a small, butterfly-shaped gland that wraps around your windpipe, has a highly important job. As the largest gland in the endocrine system, it regulates hormones and ensures growth, metabolism and development all occur at normal rates.

Approximately one-third of type 1 patients have markers for another autoimmune disease at diagnosis.;One of these diseases is thyroid disease.

When the thyroid gland is out of synch, its regulative functions are thrown off. The hormonal imbalance can result in either hyperthyroidism or hypothyroidism.

Hyperthyroidism;is caused by the thyroid gland producing too much thyroid hormone. It may be caused by Graves disease , one or more thyroid nodules, ingesting too much iodine, inflammation of the thyroid gland or taking too much thyroid medication.

Symptoms include:


  • Rapid heart rate
  • Thick skin on the knees, elbows, and shins

Hypothyroidism;is caused by thyroid gland producing too little thyroid hormone. The most common form of hypothyroidism is an disease called Hashimotos thyroiditis. Symptoms include:

  • Fatigue
  • Slow pulse
  • Intolerance to cold

Who Can And Cannot Take Levothyroxine

Can synthroid and vitamin d be taken together  24/7 ...

Levothyroxine can be taken by adults and children. However, levothyroxine is not suitable for some people.

Do not take levothyroxine and go back to your doctor to discuss your treatment if you have:

  • had an allergic reaction to levothyroxine or any other medicines in the past
  • an overactive thyroid
  • a health problem that affects your adrenal glands

Check with your doctor before taking levothyroxine if you have:


  • had a heart attack
  • diabetes the dose of your diabetes medicine may need to change because levothyroxine can raise blood sugar levels

Blood Sugar Stress Hormones Connections

So what is the connection between blood sugar and stress hormones and your thyroid. Well, blood sugar levels have a profound impact on your stress hormones and stress hormones have a very strong impact on your thyroid.

Now specifically when one ingests too much carbohydrates this may be a bowl of cereal, and a glass of orange juice and maybe a banana for breakfast for example. Which is way too much carbohydrate for someone to ingest in a meal.

This will cause blood sugar levels to go high, as you see in this graph. This high blood sugar will give some people a little big of jolt of energy, known as a sugar rush, will also cause the body to release high amounts of insulin. This insulin is strongly implicated in weight gain, in insulin resistance and in;diabetes. Now because the body is not ideally suited to deal with high levels of;carbohydrate intake the body can over react and push your blood sugar too low, as you can see here with this lull on this graph. That is known as reactive hypoglycemia, this is where your blood sugar go to low. When that happens, this is what many people will recognize as the afternoon energy dip/sweet craving. So when blood sugar gets low people tend to become fatigued and crave sweets. So this is why many people reach for caffeine, caffeine and sugar, sugar, some sort of stimulate to help bring up their low blood sugar.

A Caveat About Thyroid Testing

Left untreated, both hypothyroidism and hyperthyroidism can worsen blood sugar management and alter medication requirements. Therefore, individuals with diabetes should regularly monitor their thyroid functionand everyone with a thyroid disorder should be periodically screened for diabetes.

Theres one caveat about thyroid testing. If your TSH test results come back within the normal range but you have symptoms of hypothyroidism, request additional testing for total and free T3, T4, and thyroid antibodies.

Subclinical hypothyroidism causes symptoms in many patientsespecially womenand may increase the risk of diabetic complications. Yet many physicians rely solely on TSH results and refuse to dig deeper. Consequently, hypothyroidism often goes undiagnosed and untreated.

When Should You Get Tested For Thyroid Disease

Since thyroid disease and diabetes often go hand in hand and can have significant implications for your diabetes management, the American Diabetes Association Standards of Medical Care in Diabetes2019 recommend frequent screenings for thyroid disease in people living with diabetes.


People living with type 1 diabetes should be tested for autoimmune thyroid disease after diagnosis and have periodic follow-up screenings, even if they show no symptoms of thyroid disease. There are no screening guidelines as such for people living with type 2 diabetes, however, some recommend that women over 50 living with type 2 diabetes should be tested regularly for thyroid disease.

If you display any of the symptoms listed above and live with diabetes, please consider getting tested for thyroid disease, its as easy as a simple blood test.

All you need is a thyroid test blood test and it might also make sense for people living with type 1 diabetes to get an antibody test.

Thyroid Disorder And Diabetes

Type 1 Diabetes: High Blood Sugar At School

People with diabetes have an increased risk of developing thyroid disorder. In the general population, approximately 6% of people have some form of thyroid disorder. However, the prevalence of thyroid disorder increases to over 10% in people with diabetes.

Since people with one form of autoimmune disorder have an increased chance of developing other autoimmune disorders, people with Type 1 diabetes have a higher risk of autoimmune thyroid disorder. Up to 30% of women with Type 1 diabetes have some form of autoimmune thyroid disease. Postpartum thyroiditis, a form of autoimmune thyroid disease that causes thyroid dysfunction within a few months after delivery of a child, is three times more common in women with diabetes.


Although Type 2 diabetes is not an autoimmune disorder, there have been many reports showing a higher occurrence of thyroid diseases, particularly hypothyroidism, among people with Type 2 diabetes. The association between Type 2 diabetes and thyroid disorder, however, remains unexplained.

How To Keep Your Blood Sugar In A Healthy Range

In either case, the solution is to make sure your blood sugar stays within a healthy range. There are two targets to consider. The first is fasting blood glucose, which is a measure of your blood sugar first thing in the morning before eating or drinking anything. I define the normal range for fasting blood glucose as 75 95 mg/dL. Although 100 is often considered the cutoff for normal, studies have shown that fasting blood sugar levels in the mid-90s were predictive of future diabetes a decade later. And although 80 mg/dL is often defined as the cutoff on the low end, plenty of healthy people have fasting blood sugar in the mid-to-high 70s .

The second, and much more important, target is post-prandial blood glucose. This is a measure of your blood sugar 1-2 hours after a meal. Several studies have shown that post-prandial blood glucose is the most accurate predictor of future diabetic complications and is the first marker to indicate dysglycemia.

Normal post-prandial blood sugar one to two hours after a meal is 120 mg/dL. Most normal people are under 100 mg/dL two hours after a meal.


Now that we know the targets, lets look at how to meet them. If youre hypoglycemic, your challenge is to keep your blood sugar above 75 throughout the day. The best way to do this is to eat a low-to-moderate carbohydrate diet , and to eat frequent, small meals every 2-3 hours (to ensure a continuous supply of energy to the body.

Common Questions About Levothyroxine

The thyroid gland in your neck makes a hormone called thyroxine. Thyroxine controls how much energy your body uses . It’s also involved in digestion, how your heart and muscles work, brain development and bone health.

When the thyroid gland does not make enough thyroxine , many of the body’s functions slow down. Some of the most common symptoms of an underactive thyroid gland are:

  • tiredness
  • weight gain
  • feeling depressed

Levothyroxine is a synthetic version of thyroxine. You take levothyroxine tablets to replace the thyroxine that your thyroid gland cannot produce and prevent the symptoms of hypothyroidism.

Levothyroxine starts working straight away, but it may be several weeks before your symptoms start to improve and you feel any different.


Treatment with levothyroxine is usually lifelong. If you stop taking levothyroxine your symptoms are likely to come back.

Yes, it’s safe to take levothyroxine for a long time, even many years. High doses of levothyroxine over a long time can sometimes cause weakening of the bones .

This should not happen if you are on the right dose. It’s important to have regular blood tests to make sure your dose is not too high.

There’s no clear evidence to suggest that taking levothyroxine will reduce fertility in either men or women.

However, speak to a pharmacist or your doctor if you’re trying to get pregnant. They may want to review your treatment.


Yes, levothyroxine should not affect your ability to drive or ride a bike.

How To Naturally Control Blood Sugar Levels

Specific symptoms may indicate you are on a blood sugar rollercoaster.

For example, you may experience:

  • Irritability if you miss a meal
  • Eating food to relieve fatigue
  • Feeling anxiety or nervousness
  • Difficulty losing weight
  • Increased weight gain around the waistline

If you experience these symptoms, you can rest easy knowing that many of these symptoms can improve with lifestyle and dietary adjustments. Ideally, you catch yourself on this rollercoaster early, as waiting too long may lead to insulin resistance or, eventually, type 2 diabetes. Try these natural solutions to balancing your blood sugar.


Diet

Managing your diet is the most effective way to balance your blood sugar. Understanding our nutritional needs can be overwhelming, especially if you have a health condition like Hashimoto√Ęs. We know that carbohydrates are the primary source of glucose, so limiting carbs is imperative. However, knowing good carbs from not-so-good carbs can be challenging. The Glycemic Index is an easy-to-use tool to help you choose carbohydrates that have minimal blood sugar effects. When you eat carbohydrates, always eat some protein, too, to keep blood glucose levels steady.

Exercise

Get quality sleep

When we do not get enough sleep, our cortisol levels increase, and our metabolic hormones can be affected. Often, these disturbances can lead to poor dietary choices that inevitably increase our blood sugar.

Drink water

Too Much Synthroid Symptoms

Synthroid is a synthetic form of T4 , a hormone secreted by the follicular cells of the thyroid gland.; Individuals with insufficient levels of thyroxine exhibit symptoms of hypothyroidism such as: depression, lethargy, malaise, and sleepiness.; Regular administration of synthroid is thought to reverse symptoms of hypothyroidism and normalize all neurophysiological processes impaired by low thyroxine .

When initiating treatment, certain patients may run the risk of taking too much synthroid.; In a majority of cases, individuals that take too much synthroid do so unintentionally.; It is common for patients to misinterpret dosing instructions given by a medical professional and/or pharmacist and mistakenly ingest larger than instructed doses.

In other cases, a doctor may inadvertently prescribe too high of a synthroid dosage for a particular patient.; Since synthroid has a narrow therapeutic index for dosing, even slightly too much of the synthetic hormone may provoke a tailspin of unwanted symptoms, most of which resemble hyperthyroidism .; If you are taking synthroid and suspect that you may have ingested an excessive amount, it is important to beware of severe synthroid side effects and adverse reactions.

Whats Up With Thyroid Diagnosis & Treatment

If youre experiencing any of the symptoms described, youll want to see your endocrinologist or primary care physician ASAP. You may be referred to a doctor who specializes in thyroid issues , but your endocrinologist will know exactly how to diagnosis you. The primary way to diagnose thyroid disease is something called a TSH test, which checks the amount of thyroid-stimulating hormone in your system. Its a very easy and inexpensive blood test, so dont delay if you think you have symptoms!

However, sometimes the test will come back false-normal, so testing for antibodies or having a full Thyroid Panel can also turn up things that the TSH test might leave out.

Autoimmune thyroid diseases, like Hashimotos Disease, are usually much easier to manage than diabetes. The hormone replacement treatment comes in pill form, so taking the medication is easy-peasey. But some patients have difficulty finding the right type of thyroid replacement pill. While there are two types of natural thyroid hormones, called T3 and T4, only T4 is found in the common thyroid replacements. For many people, this doesnt work well. In theory, T4 medication would also convert to T3, but research suggests this doesnt always happen. Youll want to do your homework and make sure you get on the right treatment for you!

How Is Thyroid Dysfunction Diagnosed And Treated

Some of the symptoms of thyroid dysfunction and diabetes are similar. Both hyperthyroidism and diabetes can cause unexplained weight loss and fatigue, for example. This can make diagnosis tricky.

Anyone who has diabetes and suspects they may have thyroid dysfunction should speak to their healthcare team. Doctors will usually recommend a blood test that looks at the level of thyroid hormones. The test is quick and easy and will help doctors make sure people get the treatment they need.

People with diabetes and thyroid dysfunction will usually need to work with their healthcare team to adjust their diabetes medication. Those with hypothyroidism, for example, tend to need lower doses of insulin because their bodys take longer to process it.

The most common treatment for hypothyroidism is a medication that experts call levothyroxine. It is a pill that people usually take once a day. Their healthcare team will then carry out regular blood tests to check the drug is working.

It can take several months for the treatment to have an effect. Most people will need to take the medicine for the rest of their lives.

Doctors might recommend one of a variety of treatments for hyperthyroidism. Medicines like methimazole and propylthiouracil can help to control the amount of thyroid hormone the body makes. They tend to take between one and two months to work.
