What Is The Difference Between Hypothyroidism And Hyperthyroidism
The thyroid is a butterfly-shaped gland situated in the neck, which is responsible for almost all metabolic processes of the body. Thyroid hormones dominate the functioning of the brain, muscles, heart, and other bodily systems. Though it is the same gland, an underactive or an overactive thyroid can lead to various conditions that present with distinct symptoms.
How Are Thyroid Problems Diagnosed
Usually patients with thyroid disease see their doctor when they develop any of the signs or symptoms above. Based on that, plus a physical exam, the next step is to get blood work done.;
A blood test for thyroid stimulating hormone is the best screening test for thyroid problems. Because TSH stimulates production of your thyroid hormones, TSH is high when your body is not making enough thyroid hormone and low when it makes too much . Blood tests can also show levels of antibodies in the case of Hashimotos thyroiditis or Graves disease. Your body produces antibodies to fight off foreign invaders such as viruses or bacteria, and antibodies in your blood could mean that your body is treating your thyroid as a threat.
Depending on what those tests show, your doctor may want to get a scan of your thyroid gland. Ultrasound is a commonly used imaging method, especially for hyperthyroidism.

UM is one of the few places in the country that has a multidisciplinary group dedicated to the treatment of patients with Graves disease. UMs multidisciplinary group consists of endocrinologists, endocrine surgeons, ophthalmologists, nuclear medicine physicians, rheumatologists and psychiatric professionals. Our group sees Graves disease patients from around the country and is involved with one of the most well-known national organizations concentrating on helping patients and families coping with Graves disease and Graves eye disease. Our group routinely publishes papers with new research results on Graves disease.;
The ophthalmologists in our group specialize in the treatment of Graves eye disease which can require complex management. Most ophthalmologists have little experience treating patients with Graves disease and Graves eye disease. For those patients with Graves eye disease, it is the severity of the eye disease which drives the selection of the type of treatment for hyperthyroidism if these two problems occur together.
While those patients with no Graves eye disease or only mild eye disease may be candidates for any of the three types of treatments for hyperthyroidism, those who have moderate to severe eye disease are often referred for surgical thyroidectomy as RAI has a higher chance of worsening the eye disease than surgery does.

Not necessarily. You can experience both, although hypothyroidism is more common than hyperthyroidism. Both conditions can become a problem during pregnancy, as hormones are in flux. Hyperthyroidism and hypothyroidism can cause problems for both mother and baby. This is why women who have thyroid disease get tested more frequently during pregnancy and may need medication and/or dose changes.
Differential Diagnosis Investigations And Treatment
Given the unusual history of oscillating hyperthyroidism and hypothyroidism, a radionuclide Tc99;m thyroid scan was arranged to distinguish between thyroiditis and GD . The scan showed increased uptake bilaterally, with total uptake of 6.1% consistent with active GD, with no retrosternal extension. TSH receptor antibody was positive at 7.3;IU/L . Thyroid function tests showed a free T4 of 16;pmol/L , free T3 of 7.0;pmol/L and TSH of <0.05;mU/L .

Hypothyroidism Vs Hyperthyroidism: Whats The Difference
Were you recently diagnosed with hypothyroidism? If so, youre likely aware your bodys thyroid gland is underactive. And youre probably all too familiar with some of the associated symptoms like tiredness, constipation, and forgetfulness. These symptoms are frustrating. But with the right treatment plan, they can become manageable.

Treatment Differences Between Hypothyroidism And Hyperthyroidism
Treatment for hypothyroidism and hyperthyroidism differs. While the key to hypothyroidism treatment is to get your thyroid levels up, hyperthyroid treatment focuses on lowering hormone levels. This can be a hit-and-miss process at first until your doctor figures out the right amounts of medicine you need for your thyroid to stabilize.
With hypothyroidism, lifelong use of medication is often required. Levothyroxine is standard in hypothyroid treatment. It helps replace missing thyroxine hormones in the body. While you may need occasional dosage adjustments, most people dont outgrow taking this medication.
Hyperthyroid treatment, on the other hand, may be temporary. Antithyroid medications work by stopping the thyroid gland from making too many hormones. These dont damage the thyroid whatsoever. Sometimes beta-blockers are also used to minimize the effects of too much thyroid hormone on the body, such as heart palpitations.
More severe cases of hyperthyroidism may require radioiodine treatments. Radioactive iodine destroys thyroid cells to decrease the release of hormones in the body. This approach is used when medications have failed. It often results in hypothyroidism, for which youll then need to take thyroid hormone medications.
What Are The More Serious Complications Of Hyperthyroidism
People with advanced and extreme hyperthyroidism face a ramshackle of problems, some of them life-threatening. The good news, though, is many patients do not reach this level of severity. Complications can include:
- Graves ophthalmopathy or Thyroid Eye Disease , which may soon be treatable using a new drug called Teprotumumab
- Irregular heartbeat, which can lead to:
- blood clots
- other heart problems
Bottom line: The longer you have an overactive thyroid and go without treatment, the greater the risk of lifelong complications, even after treatment. As over 60 percent of people with thyroid disease go undiagnosed, its important to listen to your body before reversible symptoms like weight loss and insomnia become life-threatening issues such as irregular heartbeat , bone loss , and infertility .

Lactating mothers are recommended to take ATDs immediately after breastfeeding.
The Differences Between Hypothyroidism & Hyperthyroidism
Hypothyroidism vs. Hyperthyroidism
Weve all heard the terms Hyperthyroidism and Hypothyroidism and more often than not,these two terms are casually used in lieu of the other whichever one is more convenientlyremembered. But whats really the deal with these thyroidisms? Lets start by defining whatgland is affected by both these afflictions. The Thyroid Gland is a large ductless gland in theneck which secretes hormones regulating growth and development through the rate ofmetabolism. In laymans terms, the thyroid gland plays a big role in the growth and developmentof our body along with how fast we are able to convert our food intake into energy that our bodycan use. Now that we have a basic understanding of what the Thyroid gland is for and how itaffects our body, lets delve deeper into the what these two isms are and how theyre differentfrom one another.
HyperthyroidismHyperthyroidism occurs when the body makes too much of the thyroid hormones,thyroxine and triiodothyronine , and becomes overly active. Irritation of thethyroid gland known as thyroiditis allows too much thyroid hormone to enter the bodysbloodstream. This can then lead to pain and discomfort. Medications, radioactive iodine,or surgery are possible treatment options of hyperthyroidism.

Can You Have Hypothyroidism And Hyperthyroidism At The Same Time
It is not possible to have both hypothyroidism and hyperthyroidism at the same time. However, it is possible to go back and forth between these two thyroid problems.
If you are currently receiving treatment for a thyroid problem and your thyroid function begins to shift between underactive and overactive, your medication may be the cause and you should talk to your doctor right away.
This is according to;;who also explains, If you dont have a history of thyroid problems, the most common reason for a change in thyroid function is inflammation of the thyroid gland . Initially, thyroiditis leads to overactive thyroid function because when the thyroid first becomes inflamed, it releases all its stored hormones. After that, the thyroid slowly begins to return to normal, but it doesnt maintain its usual hormone production. So once the hormone stores are depleted, hypothyroidism develops. Its outcome depends on the type of thyroiditis, as follows.
Are Hyperthyroidism And Hypothyroidism Permanent
Hyperthyroidism is not necessarily permanent. Your doctor may recommend removing your thyroid if hyperthyroidism returns after you stop taking medication or if you have side effects from the medications. Surgery and radioactive iodine are more likely to stop hyperthyroidism. However, you may develop hypothyroidism after these treatments and require daily medication for that.;
Hypothyroidism is unlikely to go away, meaning you will probably take medication for the rest of your life. Each case is different, though, so you should speak with your doctor about what to expect.

Symptoms Of Hypothyroidism Include:
- Fatigue that wont go away;
- Developing a sensitivity to the cold;
- A goiter ;
- Muscle weakness;
- Slowed mental processes; and
- Thick, puffy skin.
When the body doesnt make enough thyroxine, the body processes slow down; thats why there is almost crippling fatigue with hypothyroidism. When fatigue carries on indefinitely, its time to visit your healthcare provider to discuss the possibility of an underactive thyroid.
Many things can cause hypothyroidism, but the most common is Hashimotos disease, an autoimmune disorder, in which the body attacks the thyroid, inflaming it and reducing its function.
Overactive Vs Underactive Thyroid Symptoms
Both hyperthyroidism and hypothyroidism can cause fatigue, hair loss/thinning, muscle or joint pain, mental anguish , and many other symptoms that are common to other diseases. Doctors must use other symptoms to evaluate the risk or presence of either disorder and cannot diagnose either without a blood test.
The most common signs and symptoms of hypothyroidism manifest in ways that suggest natural processes of the body are slowed or shutting down:
- Rapid weight gain, despite lack of appetite
- Feeling cold and having cool extremities
- Slow heart rate
- Facial swelling or other swelling, such as of the limbs

Whos At Risk For Hyperthyroidism
According to the National Institute of Health , hyperthyroidism affects approximately 1.2% of the population in the US. Although it occurs in both men and women, its up to 10 times more likely in females.

- Have a family history of thyroid disease
- Have pernicious anemia
- Have primary adrenal insufficiency, also known as Addisons disease
- Consume an iodine-rich diet or medications containing iodine
- Are over the age of 60
- Were pregnant within the past 6 months
- Had thyroid surgery or a thyroid problem such as a goiter;also known as a swollen thyroid gland;
Though an overactive thyroid brings on a constellation of high thyroid symptoms , some of them dont seem obviously linked to the condition . Heres what to look for.
Where Can I Find Support
Hyperthyroidism impacts you physically, psychologically, and emotionally. Its critical that you have a strong network of people you trust and can turn to for support.
It starts with your family. Since thyroid disease runs in families, being honest and open with your relatives is the best policy, as you might be alerting them to a problem they didnt even know to look out for.

Causes And Risk Factors:
Hypothyroidism can sometimes be caused by autoimmune conditions such as Hashimoto disease or it can be a result of thyroid surgery or radiation treatment. Certain medications such as lithium can also cause hypothyroidism. In addition, some women develop the disorder during pregnancy and some babies are born with congenital hypothyroidism. A lack of iodine in the diet can also cause the problem but in most countries, this is rare today since iodine is added to table salt.
Hyperthyroidism Symptoms & Lab Tests
Hyperthyroidism is the EXACT opposite when compared to hypothyroidism.
This makes the diagnosis and distinguishing the two diseases relatively simple.
For example: ;
If hypothyroidism causes weight gain then hyperthyroidism causes weight loss.
If hypothyroidism causes a slow heart rate then hyperthyroidism causes a rapid heart rate and palpitations.
If hypothyroidism causes constipation then hyperthyroidism causes diarrhea.
These opposites tend to hold true for most symptoms, but there is some overlap in symptoms such as hair loss and fatigue.
Both hypothyroidism and hyperthyroidism can lead to these non-specific symptoms as well.
The good news is that, even if there is some overlap, you can distinguish between the conditions based on other symptoms and lab tests.
What Happens to Thyroid Lab Tests if you have Hyperthyroidism?
Hyperthyroidism is often caused by EXCESSIVE or INCREASED release and production of thyroid hormones in the body.
This release of thyroid hormone is easy to check and identify in the blood serum and usually presents as follows…
Hyperthyroid Symptoms Checklist:
It’s important to realize that the treatment for hyperthyroidism is to reduce the amount of thyroid hormone being produced by the thyroid gland.
This often results in procedures to either remove or destroy the thyroid gland.
Once the thyroid gland is removed or destroyed then patients may become hypothyroid.

Complications Seen In Hyperthyroidism
Clinical manifestation varies depending on several factors, such as the patients age and sex, comorbidities, duration of the disease, and cause. Older patients present with fewer and less pronounced symptoms than do younger patients, but are more likely to develop cardiovascular complications. When compared with people older than 60 years with a healthy thyroid, those who are hyperthyroid have three times the risk of atrial fibrillation. Embolic stroke related to atrial fibrillation secondary to hyperthyroidism is significantly more prevalent than embolic stroke related to atrial fibrillation from non-thyroidal causes., However, anticoagulant therapy in patients with atrial fibrillation secondary to hyperthyroidism is still debated. Atrial fibrillation is also thought to be an independent predictor of the development of congestive heart failure in patients with hyperthyroidism. An increased risk of all-cause mortality was reported in patients with hyperthyroidism, with heart failure being the main cause of cardiovascular events.
Other complications of long-standing thyrotoxicosis include osteoporosis and abnormalities in the reproductive system, such as gynaecomastia in men and decreased fertility and menstrual irregularities in women.
Suffering From Both Hypothyroidism And Hyperthyroidism
As unbelievable as it sounds, some people can and do suffer from both thyroid issues, though the symptoms dont present themselves simultaneously. It could be a flare-up of thyroiditis, in which the patient has hypothyroidism but the thyroid occasionally goes into overdrive, presenting symptoms of hyperthyroidism, even though its still on its way to burning out. So you might experience weight loss and fatigue , plus nervousness, and then a few months later the opposite starts to happen: crushing fatigue, weight gain, depression, and dry skin.
In some rare cases, Hashimotos disease and Graves disease coexist in the patient, putting them through cycles between an overactive and underactive thyroid. If you have hypothyroidism with hyperthyroidism symptoms, talk to your doctor about getting a full antibody profile to determine if both are, in fact, present.
