Hyperthyroidism
With hyperthyroidism, thyroid hormone levels are excessive. People may experience a racing heart, heat intolerance, sweating, tremor, nervousness, difficulty sleeping or unexplained weight loss.
Overactive Thyroid Health
Understanding Hyperthyroidism
Hyperthyroidism, also known as an overactive thyroid, occurs when the thyroid produces too much thyroid hormone. This can speed up many of the body’s functions and may cause symptoms such as a fast or irregular heartbeat, feeling hot, sweating, tremor, anxiety, difficulty sleeping, muscle weakness and unexplained weight loss.
Hyperthyroidism requires appropriate medical assessment and management. At Morkare Natural Clinic, we provide complementary naturopathic and nutritional support alongside care from your GP, endocrinologist or other medical practitioners.
Quick Answer
What Is Hyperthyroidism?
Hyperthyroidism is a condition in which the thyroid gland produces more thyroid hormone than the body needs. Because thyroid hormones influence metabolism and many other body systems, excessive thyroid hormone can affect the heart, nervous system, digestion, muscles, body temperature, menstrual cycle and energy levels.
Graves’ disease is a common autoimmune cause of hyperthyroidism, but an overactive thyroid can have other causes. Blood tests are used to assess thyroid function, and further investigation may be required to determine why thyroid hormone levels are elevated.
Understanding the Difference
Hyperthyroidism vs Hypothyroidism: What’s the Difference?
The terms sound similar, but they describe opposite patterns of thyroid function. Hyperthyroidism involves excessive thyroid hormone activity, while hypothyroidism involves insufficient thyroid hormone production.
Hypothyroidism
With hypothyroidism, the thyroid does not produce enough thyroid hormone. Symptoms may include fatigue, feeling cold, constipation, dry skin, brain fog and changes in weight.

Overactive Thyroid Symptoms
What Are the Symptoms of Hyperthyroidism?
Hyperthyroidism can affect multiple body systems. Symptoms vary between individuals and may develop gradually or become more noticeable over time.
01
Fast or Irregular Heartbeat
You may notice a racing heart, pounding heartbeat, palpitations or changes in heart rhythm.
02
Heat Intolerance
Feeling unusually hot or sweating more than normal can occur when thyroid hormone activity is excessive.
03
Unexplained Weight Loss
Some people lose weight despite eating normally or having an increased appetite.
04
Tremor
A fine shaking or trembling of the hands or fingers can occur with an overactive thyroid.
05
Anxiety & Restlessness
Some people feel unusually nervous, restless, irritable or unable to relax.
06
Difficulty Sleeping
Feeling physically or mentally overstimulated may make it harder to fall asleep or stay asleep.
07
Muscle Weakness
Muscle weakness, reduced strength or increased fatigue may develop in some people.
08
Frequent Bowel Movements
Increased bowel frequency or changes in digestion can occur when body processes are accelerated.
09
Menstrual Changes
Hyperthyroidism can occur alongside changes in menstrual patterns and may be relevant when assessing reproductive health.
Important:
These symptoms are not specific to hyperthyroidism. Anxiety, palpitations, weight changes, sweating and sleep disturbance can have many possible causes. Appropriate medical assessment and thyroid testing are important.
Understanding the Cause
What Causes Hyperthyroidism?
Hyperthyroidism is not a single disease. Several different conditions can result in excessive thyroid hormone activity, so identifying the underlying cause is an important part of medical assessment.
Graves’ Disease
Graves’ disease is an autoimmune condition that can stimulate the thyroid to produce excessive thyroid hormone. It may also be associated with eye symptoms in some people.
Overactive Thyroid Nodules
In some cases, one or more thyroid nodules can produce thyroid hormone independently and contribute to hyperthyroidism.
Thyroiditis
Inflammation of the thyroid can sometimes cause stored thyroid hormone to be released into the bloodstream, resulting in a temporary period of hyperthyroidism.
When to Seek Assessment
When Should an Overactive Thyroid Be Investigated?
If you are experiencing persistent symptoms suggestive of hyperthyroidism, particularly changes in heart rate, unexplained weight loss, tremor, heat intolerance or significant changes in energy, discuss these symptoms with your medical practitioner.
Heart Palpitations
A persistent racing, pounding or irregular heartbeat should be medically assessed rather than assumed to be caused by stress or anxiety.
Unexplained Weight Loss
Losing weight without intentionally changing your diet or activity level can have many causes and deserves appropriate investigation.
Abnormal Thyroid Results
If previous blood tests suggest excessive thyroid hormone activity, your doctor may recommend further testing to determine the underlying cause.
When Hyperthyroid Symptoms Need Urgent Medical Attention
Seek urgent medical care if you develop severe or rapidly worsening symptoms such as a very fast heartbeat, significant breathing difficulty, chest pain, fainting, severe agitation, confusion or a high fever.
Hyperthyroidism can occasionally become a medical emergency, so severe symptoms should not be managed with supplements or naturopathic treatment alone.

Thyroid Testing
How Is Hyperthyroidism Diagnosed?
Hyperthyroidism requires medical diagnosis. Your doctor will usually consider your symptoms, medical history, physical examination and thyroid blood tests. Further investigations may be recommended to determine why the thyroid is overactive.
TSH
Thyroid-stimulating hormone, or TSH, is commonly measured when investigating thyroid function. In hyperthyroidism, TSH is often reduced, but results need to be interpreted alongside other thyroid markers and your clinical presentation.
Free T4 & Free T3
Your doctor may measure free T4 and free T3 to assess circulating thyroid hormone levels and better understand the pattern of thyroid dysfunction.
Thyroid Antibodies
Where Graves’ disease or another autoimmune thyroid condition is suspected, your medical practitioner may consider relevant thyroid antibody testing as part of the investigation.
Already have thyroid blood test results?
Bring your recent pathology to your Morkare consultation. We can review your existing results alongside your symptoms, diet, supplements, medications and current medical thyroid care.
Autoimmune Hyperthyroidism
What Is Graves’ Disease?
Graves’ disease is an autoimmune condition and a common cause of hyperthyroidism. In Graves’ disease, the immune system produces antibodies that stimulate the thyroid gland, which can result in excessive thyroid hormone production.
This can lead to typical hyperthyroid symptoms such as palpitations, heat intolerance, sweating, tremor, nervousness, difficulty sleeping and changes in weight.
Some people with Graves’ disease may also develop eye symptoms. Graves’ disease requires appropriate medical assessment, treatment and ongoing monitoring.
Women’s Thyroid Health
Hyperthyroidism Symptoms in Women
Hyperthyroidism can affect both men and women. In women, some thyroid symptoms may overlap with hormonal changes, stress, anxiety or perimenopause, which can make the underlying cause less obvious without appropriate testing.
Menstrual Changes
Thyroid dysfunction can affect menstrual patterns. Changes in your cycle should be considered alongside your broader hormonal and medical history.
Anxiety & Palpitations
Restlessness, anxiety and a racing heart can sometimes be attributed to stress or hormonal changes when an overactive thyroid may also need to be considered.
Heat & Sleep Changes
Feeling unusually hot, sweating and disturbed sleep may overlap with perimenopause symptoms. Persistent or unexplained symptoms deserve appropriate assessment.
Symptoms can overlap.
Hot flushes, poor sleep, anxiety, palpitations and menstrual changes do not automatically mean perimenopause or hyperthyroidism. Appropriate assessment helps identify what may actually be contributing to your symptoms.
Preconception & Pregnancy
Hyperthyroidism, Fertility & Pregnancy
Thyroid function is important during preconception and pregnancy. If you have hyperthyroidism and are planning a pregnancy, experiencing fertility concerns or are already pregnant, your thyroid condition and treatment should be appropriately managed by your medical team.
Planning for Pregnancy
If you have a known overactive thyroid, discuss pregnancy planning, current thyroid function and your medications with your doctor before trying to conceive.
Medical Monitoring
Thyroid function needs appropriate monitoring during pregnancy. Your GP, endocrinologist and maternity care team can determine the medical treatment and monitoring required.
Individualised Support
Nutritional requirements change during preconception and pregnancy. Supplements should be reviewed carefully when thyroid disease and thyroid medication are involved.

Fertility Naturopath Brisbane
service.
Hyperthyroidism & Nutrition
What Is the Best Diet for Hyperthyroidism?
There is no single diet that treats hyperthyroidism. Medical management of the underlying thyroid condition remains important, while nutrition can be used to support adequate energy, protein and nutrient intake according to your individual needs.
Maintain Adequate Nourishment
An overactive thyroid can increase metabolic demands. If you are losing weight or struggling to maintain adequate intake, nutrition may need particular attention.
Support Muscle Health
Hyperthyroidism can be associated with muscle weakness and loss of strength. Adequate dietary protein can form part of an individualised nutritional plan.
Avoid Extreme Thyroid Diets
Hyperthyroidism should not be managed by following restrictive online diets or attempting to control thyroid hormone production through food alone.
An Important Supplement Question
Should You Take Iodine if You Have Hyperthyroidism?
Do not assume that an iodine supplement is appropriate simply because you have a thyroid condition.
Iodine is required for normal thyroid hormone production, but excessive iodine intake can affect thyroid function and may be problematic in some people with existing thyroid disease.
If you have hyperthyroidism, Graves’ disease or another diagnosed thyroid condition, discuss iodine-containing supplements with an appropriately qualified health professional who understands your diagnosis and current medical treatment.
Supplement Safety
What Supplements Should You Avoid With an Overactive Thyroid?
Supplements marketed for “thyroid support” are not automatically appropriate for hyperthyroidism. Products can contain iodine, herbs, stimulatory ingredients or combinations that may not suit someone with an overactive thyroid.
Iodine-Containing Products
Check the ingredients of thyroid, kelp and seaweed-based supplements rather than assuming that additional iodine is beneficial.
Generic Thyroid Formulas
A supplement labelled for “thyroid health” may not distinguish between an underactive and overactive thyroid. These are very different clinical situations.
Multiple Supplements at Once
Starting several products simultaneously can make it difficult to know what is helping, what is unnecessary and whether anything is interacting with your current treatment.
Tell Your Health Practitioners What You Are Taking
If you are receiving treatment for hyperthyroidism, tell your doctor, pharmacist and naturopath about supplements, herbs and other complementary medicines you are using or considering.
Feeling Wired & Exhausted
Hyperthyroidism, Anxiety, Stress & Sleep
An overactive thyroid can leave some people feeling physically overstimulated. You may feel restless, anxious, unable to switch off or exhausted while still finding it difficult to sleep.
These symptoms can have a significant effect on quality of life, but they should not simply be dismissed as stress or anxiety when hyperthyroidism is present or suspected.
Alongside appropriate medical thyroid treatment, supportive strategies around sleep, nutrition, recovery and lifestyle may help address the broader impact these symptoms are having on your wellbeing.
Complementary Thyroid Care
Can a Naturopath Help With Hyperthyroidism?
Naturopathic care can provide complementary support for people with diagnosed hyperthyroidism, but it should not replace medical treatment or monitoring.
At Morkare, our role is to look at nutrition, nutrient intake, sleep, stress, digestive health, energy and other individual concerns while your underlying thyroid condition is appropriately medically managed.
Support Nutritional Needs
We can review your diet, appetite, weight changes, protein intake and nutritional adequacy to identify areas where additional support may be appropriate.
Sleep, Stress & Recovery
We consider how thyroid symptoms are affecting sleep, energy and daily wellbeing and develop practical supportive strategies around these areas.
Work Alongside Medical Treatment
Your GP or endocrinologist remains responsible for diagnosing and medically treating hyperthyroidism. Our naturopathic approach is designed to complement that care rather than replace it.

Common Search Question
Can Hyperthyroidism Go Away?
Whether hyperthyroidism is temporary or requires longer-term management depends on the underlying cause.
Some forms of thyroiditis can cause a temporary period of excessive thyroid hormone release, while conditions such as Graves’ disease or overactive thyroid nodules may require specific medical treatment and ongoing monitoring.
This is why identifying the cause of an overactive thyroid is important rather than trying to manage symptoms alone.
Why Treatment Matters
What Happens if Hyperthyroidism Is Left Untreated?
Untreated or poorly controlled hyperthyroidism can affect more than energy and weight. Excess thyroid hormone can place additional strain on several body systems, particularly the cardiovascular system.
Heart & Circulation
Hyperthyroidism can affect heart rate and rhythm. This is one reason persistent palpitations or a racing heartbeat should be medically assessed.
Muscles & Bones
Ongoing excessive thyroid hormone activity can affect muscle strength and may also have consequences for bone health over time.
Thyroid Crisis
Rarely, severe uncontrolled hyperthyroidism can develop into a medical emergency known as thyroid storm or thyroid crisis.
Hyperthyroidism Should Not Be Self-Treated
If you have been diagnosed with hyperthyroidism, continue the medical treatment and monitoring recommended by your doctor or endocrinologist.
Naturopathic and nutritional care should complement appropriate medical treatment rather than replace it.

Hyperthyroidism Frequently Asked Questions
Answers to common questions about overactive thyroid symptoms, Graves’ disease, testing, treatment, diet, pregnancy and complementary care.
What is hyperthyroidism?
Hyperthyroidism, also called an overactive thyroid, occurs when there is too much thyroid hormone activity in the body. This can speed up many body processes and affect heart rate, temperature regulation, digestion, muscles, sleep and weight.
What are the main symptoms of hyperthyroidism?
Common symptoms can include a fast or irregular heartbeat, palpitations, feeling unusually hot, excessive sweating, tremor, nervousness, difficulty sleeping, muscle weakness, increased bowel movements and unexplained weight loss.
What causes hyperthyroidism?
Hyperthyroidism can have several causes. Graves’ disease is a common autoimmune cause. Other causes include overactive thyroid nodules and some forms of thyroiditis.
Is Graves’ disease the same as hyperthyroidism?
No. Hyperthyroidism describes excessive thyroid hormone activity. Graves’ disease is an autoimmune condition that can cause hyperthyroidism.
What is the difference between hyperthyroidism and hypothyroidism?
Hyperthyroidism involves excessive thyroid hormone activity, while hypothyroidism occurs when the thyroid does not produce enough thyroid hormone. Their symptoms, causes and treatments are different.
How is hyperthyroidism diagnosed?
Diagnosis usually involves medical assessment and thyroid blood tests. TSH, free T4 and free T3 may be measured, and further testing may be recommended to determine the underlying cause.
Can hyperthyroidism go away?
It depends on the cause. Some forms of thyroiditis may cause temporary hyperthyroidism, while Graves’ disease or overactive thyroid nodules may require specific treatment and ongoing monitoring.
What happens if hyperthyroidism is untreated?
Uncontrolled hyperthyroidism can affect the heart, muscles, bones and other body systems. Rarely, severe hyperthyroidism can become a medical emergency. Appropriate diagnosis, treatment and monitoring are important.
Can hyperthyroidism cause anxiety?
Hyperthyroidism can cause symptoms such as nervousness, restlessness, irritability, tremor, palpitations and difficulty sleeping, which may feel similar to anxiety. Persistent symptoms should be appropriately assessed rather than automatically attributed to stress.
Can hyperthyroidism cause weight loss?
Yes. An overactive thyroid can increase metabolic activity, and some people lose weight despite eating normally or having an increased appetite. Unexplained weight loss should be medically investigated.
What foods should you avoid with hyperthyroidism?
There is no single list of foods that everyone with hyperthyroidism must avoid. However, excessive iodine intake may be inappropriate for some people with an overactive thyroid. Discuss major dietary restrictions and iodine-containing products with your healthcare team.
Should I take iodine for hyperthyroidism?
Do not automatically take iodine because you have a thyroid condition. Excessive iodine can affect thyroid function and may worsen hyperthyroidism in some circumstances. Iodine supplements should be discussed with an appropriately qualified healthcare professional familiar with your thyroid diagnosis.
Can hyperthyroidism affect pregnancy?
Yes. Appropriate thyroid management is particularly important during pregnancy. If you have hyperthyroidism and are pregnant or planning pregnancy, work with your doctor and relevant maternity healthcare team to manage and monitor your thyroid condition.
Can a naturopath help with hyperthyroidism?
Naturopathic care can provide complementary support around nutrition, nutrient intake, sleep, stress, digestive health and lifestyle. It should not replace medical treatment or monitoring for hyperthyroidism.
Can I stop my thyroid medication if I feel better?
Do not stop, reduce or change prescribed thyroid medication without speaking with the medical practitioner responsible for your treatment. Feeling better does not necessarily mean the underlying thyroid condition has resolved.
Do you offer hyperthyroidism consultations online?
Yes. Morkare Natural Clinic provides complementary thyroid naturopath consultations in Brisbane and via telehealth Australia-wide.
