01
Fatigue
Persistent tiredness, low stamina or feeling exhausted despite adequate rest can occur when thyroid function is reduced.
Underactive Thyroid Health
Understanding Hypothyroidism
Hypothyroidism, also known as an underactive thyroid, occurs when the thyroid gland does not produce enough thyroid hormone for the body’s needs. Symptoms can include persistent fatigue, feeling cold, constipation, dry skin, hair changes, brain fog, changes in weight, low mood and menstrual changes.
At Morkare Natural Clinic, we provide personalised naturopathic and nutritional support for people with hypothyroidism alongside appropriate thyroid testing, prescribed medication and medical monitoring where required.
Quick Answer
What Is Hypothyroidism?
Hypothyroidism is a condition in which the thyroid gland does not produce enough thyroid hormone. Thyroid hormones influence metabolism and many body functions, so reduced thyroid activity can affect energy, temperature regulation, digestion, concentration, skin, hair, muscles, mood and reproductive health.
Hypothyroidism is diagnosed through medical assessment and thyroid blood tests. Treatment depends on the cause and severity, and some people require thyroid hormone replacement prescribed and monitored by their doctor.
Underactive Thyroid Symptoms
What Are the Symptoms of Hypothyroidism?
Symptoms of an underactive thyroid can develop slowly and may initially be easy to overlook. The symptoms also overlap with many other health conditions, so thyroid testing is important when hypothyroidism is suspected.
02
Feeling Cold
Increased sensitivity to cold or feeling colder than the people around you can be associated with an underactive thyroid.
03
Weight Changes
Reduced thyroid function can contribute to changes in weight and may make weight management more difficult for some people.
04
Brain Fog
Difficulty concentrating, slower thinking, forgetfulness or reduced mental clarity may occur.
05
Hair Changes
Increased hair shedding, thinning or changes in hair texture can occur, although hair loss can have many other causes.
06
Dry Skin
Skin may become unusually dry, rough or more difficult to keep hydrated.
07
Constipation
Slower bowel function and constipation can occur when thyroid hormone levels are low.
08
Mood Changes
Some people experience changes in mood, motivation or general emotional wellbeing.
09
Muscle & Joint Symptoms
Muscle weakness, aches, cramps or joint stiffness may occur in some people with hypothyroidism.
Important: Fatigue, weight changes, hair loss, constipation and brain fog do not automatically mean you have hypothyroidism. These symptoms have many possible causes and should be considered alongside appropriate medical assessment and thyroid testing.
Women’s Thyroid Health
What Are the Symptoms of Hypothyroidism in Women?
Women may experience the general symptoms of an underactive thyroid, including fatigue, feeling cold, constipation, brain fog, dry skin, hair changes and changes in weight.
Thyroid dysfunction can also occur alongside menstrual or reproductive health concerns. The difficulty is that many of these symptoms can overlap with iron deficiency, stress, poor sleep, PCOS, perimenopause and other hormonal or medical conditions.
Rather than assuming every symptom is caused by the thyroid, it is important to look at the complete clinical picture.
Understanding Thyroid Function
Hypothyroidism vs Hyperthyroidism: What’s the Difference?
Hypothyroidism and hyperthyroidism describe opposite patterns of thyroid function. One involves too little thyroid hormone activity, while the other involves excessive thyroid hormone activity.
Hypothyroidism
Hypothyroidism occurs when the thyroid does not produce enough thyroid hormone. Symptoms may include fatigue, feeling cold, constipation, dry skin, brain fog and changes in weight.
Hyperthyroidism
Hyperthyroidism involves excessive thyroid hormone activity and may cause symptoms such as a racing heart, heat intolerance, sweating, tremor, nervousness and unexplained weight loss.
Learn About Hyperthyroidism →Understanding the Cause
What Causes Hypothyroidism?
Hypothyroidism can have different causes. Identifying the underlying cause matters because an underactive thyroid is not always the same clinical situation for every person.
Hashimoto’s Thyroiditis
Hashimoto’s is an autoimmune thyroid condition that can gradually damage thyroid tissue and reduce the thyroid’s ability to produce sufficient thyroid hormone.
Learn About Hashimoto’s Thyroiditis →Previous Thyroid Treatment
Hypothyroidism can develop following certain treatments for an overactive thyroid or after surgery involving the thyroid gland.
Other Thyroid & Medical Factors
Other causes of hypothyroidism exist, including some forms of thyroid inflammation, certain medicines and less common problems affecting thyroid hormone regulation.
Common Search Question
Is Hashimoto’s the Same as Hypothyroidism?
No. Hashimoto’s thyroiditis and hypothyroidism are closely related, but they are not the same thing.
Hashimoto’s thyroiditis is an autoimmune condition in which the immune system targets the thyroid gland.
Hypothyroidism describes a state in which the thyroid is not producing enough thyroid hormone.
Hashimoto’s can gradually lead to hypothyroidism, which is why the two terms are often used together. However, hypothyroidism can also occur for reasons other than Hashimoto’s.
If you want to understand the autoimmune side of thyroid disease in more detail, read our dedicated Hashimoto’s Thyroiditis guide →
When to Seek Assessment
When Should an Underactive Thyroid Be Investigated?
If you have persistent symptoms suggestive of hypothyroidism, a family or personal history of thyroid disease, previous abnormal thyroid results or unexplained changes in your health, discuss thyroid assessment with your medical practitioner.
Persistent Fatigue
Ongoing exhaustion that is not explained by sleep, lifestyle or other obvious factors deserves appropriate assessment rather than simply being accepted as normal.
Multiple Thyroid Symptoms
A combination of cold intolerance, constipation, hair changes, dry skin, brain fog or weight changes may be a reason to discuss thyroid testing with your doctor.
Abnormal Thyroid Results
If previous blood tests have shown changes in TSH or thyroid hormone levels, your doctor can determine whether repeat testing or further investigation is appropriate.

Thyroid Testing
How Is Hypothyroidism Diagnosed?
Hypothyroidism cannot be diagnosed from symptoms alone. Medical assessment usually includes thyroid blood tests, with results interpreted alongside your symptoms, health history, medications and other relevant clinical information.
TSH
Thyroid-stimulating hormone, or TSH, is commonly used when assessing thyroid function. In primary hypothyroidism, TSH is often elevated as the body attempts to stimulate the thyroid to produce more thyroid hormone.
Free T4
Free T4 provides information about circulating thyroxine. Your doctor may interpret free T4 together with TSH to help determine whether thyroid hormone production is reduced.
Thyroid Antibodies
If Hashimoto’s thyroiditis is suspected, your doctor may consider thyroid antibody testing, including thyroid peroxidase antibodies (TPOAb) and, where appropriate, thyroglobulin antibodies (TgAb).
Learn About Hashimoto’s Thyroiditis →
Already have thyroid pathology?
Bring your recent blood test results to your Morkare consultation. We can consider them alongside your diagnosis, symptoms, diet, supplements, prescribed medication and broader health history.
Common Search Question
What Is Subclinical Hypothyroidism?
Subclinical hypothyroidism is a pattern of thyroid blood results where TSH is elevated but free T4 remains within the laboratory reference range.
Some people have few or no obvious symptoms, while others may report symptoms commonly associated with an underactive thyroid.
Whether treatment or monitoring is appropriate depends on the individual. Factors such as the degree of TSH elevation, symptoms, thyroid antibodies, age, pregnancy or pregnancy planning, other health conditions and repeat blood results may be relevant to your doctor’s decision.
A single abnormal thyroid result should therefore be interpreted in clinical context rather than treated as an isolated number.
Thyroid & Metabolism
Can Hypothyroidism Cause Weight Gain?
Hypothyroidism can contribute to weight gain in some people because thyroid hormones play an important role in regulating metabolism.
However, weight is influenced by much more than thyroid function alone. Diet, activity, sleep, muscle mass, medications, age, hormonal changes and other health conditions can all contribute.
If weight has changed unexpectedly, the aim should be to understand the broader picture rather than assuming every kilogram is caused by the thyroid.
Hair & Thyroid Health
Can Hypothyroidism Cause Hair Loss?
Hair thinning, increased shedding or changes in hair texture can occur with hypothyroidism. However, thyroid dysfunction is only one possible contributor to hair loss.
Thyroid Function
Reduced thyroid hormone activity can affect normal hair growth and may contribute to diffuse thinning or increased shedding.
Nutritional Factors
Nutritional status can also be relevant to hair health. Where clinically appropriate, dietary intake and potential nutritional deficiencies may need consideration.
Hormonal & Other Causes
Stress, hormonal changes, illness, medications, genetics and other medical conditions can also contribute to hair loss.
Hair loss deserves proper investigation.
Rather than assuming that hair changes are entirely due to hypothyroidism, we consider thyroid health as one part of the broader clinical picture.
Persistent Symptoms
Why Am I Still Tired With Hypothyroidism?
Fatigue is one of the most commonly associated symptoms of an underactive thyroid. But persistent fatigue does not always mean that every symptom is being caused by your thyroid.
Thyroid Function & Treatment
Your doctor can determine whether your thyroid function and prescribed treatment require review based on your symptoms and appropriate blood testing.
Nutritional Status
Dietary adequacy and nutritional factors may contribute to fatigue independently of thyroid function and can be considered where clinically relevant.
Sleep, Stress & Other Factors
Poor sleep, chronic stress, hormonal changes and other health conditions can all contribute to persistent fatigue and brain fog.
If persistent exhaustion is one of your main concerns, you may also find our
Chronic Fatigue Naturopath Brisbane
resource helpful.
Women’s Health
Can Hypothyroidism Affect Periods and Fertility?
Thyroid hormones interact with reproductive health, and hypothyroidism can be associated with menstrual changes and fertility concerns in some women.
This does not mean that every irregular cycle or fertility difficulty is caused by the thyroid. Reproductive health is influenced by many factors, which is why individual assessment matters.
Changes in Your Cycle
Thyroid dysfunction can occur alongside changes in menstrual regularity or bleeding patterns. Other hormonal and medical causes may also need consideration.
Trying to Conceive
If you have known hypothyroidism and are planning pregnancy, speak with your doctor about thyroid monitoring and treatment before conception.
Look Beyond One Hormone
Fertility assessment may involve thyroid health alongside menstrual history, age, reproductive factors, nutrition and other relevant investigations.
If you are trying to conceive, explore our
Fertility Naturopath Brisbane
service for our broader preconception and fertility approach.
Pregnancy & Thyroid Health
Why Is Hypothyroidism Important During Pregnancy?
Adequate thyroid hormone is important during pregnancy. If you have diagnosed hypothyroidism and are pregnant or planning pregnancy, appropriate medical monitoring of your thyroid function is particularly important.
Thyroid medication requirements can change during pregnancy, so prescribed medication should be managed by the medical practitioner responsible for your thyroid and pregnancy care.
Do not stop or change thyroid medication because you become pregnant unless your treating doctor specifically advises you to do so.
Thyroid or Hormones?
Hypothyroidism or Perimenopause?
For women in their 40s and 50s, it can sometimes be difficult to know whether symptoms are related to thyroid function, perimenopause or a combination of factors.
Fatigue, brain fog, changes in weight, hair changes, mood changes and menstrual changes can occur in both situations.
Rather than trying to identify the cause from symptoms alone, appropriate assessment can help distinguish thyroid dysfunction from hormonal transition and other possible contributors.
Hypothyroidism & Nutrition
What Is the Best Diet for Hypothyroidism?
There is no single hypothyroidism diet that is right for everyone. Nutrition should be personalised around your thyroid condition, overall diet, nutritional requirements, symptoms, medical history and prescribed treatment.
Start With a Balanced Diet
A varied diet providing adequate protein, vegetables, fruit, whole foods and appropriate sources of essential nutrients is generally more useful than starting with unnecessary restriction.
Consider Nutritional Status
Nutritional needs vary between individuals. Dietary intake, symptoms, existing pathology and other health conditions can help determine whether particular areas require attention.
Avoid Extreme Thyroid Diets
Hypothyroidism does not automatically require a highly restrictive diet. Removing multiple foods without a clear reason can make adequate nutrition more difficult.
Common Search Question
Should You Avoid Gluten With Hypothyroidism?
A diagnosis of hypothyroidism does not automatically mean that you need to follow a gluten-free diet.
People with coeliac disease need to avoid gluten, and individual dietary recommendations may differ when another diagnosed condition is present. However, removing gluten purely because you have an underactive thyroid is not automatically necessary.
If you suspect gluten is contributing to symptoms, it is better to discuss appropriate assessment before beginning a restrictive diet, particularly if coeliac disease may need to be investigated.
Thyroid Nutrients
What About Iodine, Selenium and Thyroid Supplements?
Nutrients are important for normal thyroid physiology, but that does not mean everyone with hypothyroidism needs high-dose thyroid supplements.
More Is Not Always Better
Iodine is required to produce thyroid hormones, but excessive iodine intake can also affect thyroid function. Supplementation should be considered in the context of your individual needs and thyroid diagnosis.
Assess Before Supplementing
Selenium has roles in thyroid physiology, but supplements should not automatically be prescribed to every person with an underactive thyroid.
Check What You Are Taking
Multi-ingredient products marketed for “thyroid support” can contain iodine, herbs and other nutrients. Review supplements in the context of your diagnosis, diet, medication and existing intake.
Individualised supplementation matters.
At Morkare, we prefer to identify whether nutritional support is actually appropriate rather than assuming everyone with hypothyroidism requires the same thyroid supplement protocol.
Medication & Complementary Care
Can Naturopathic Care Replace Thyroid Medication?
No. If thyroid hormone replacement has been prescribed for hypothyroidism, naturopathic treatment should not be used as a substitute for your prescribed medication.
Thyroid medication is prescribed and monitored according to your medical diagnosis, symptoms and blood results. Do not stop, reduce or alter your dose without discussing this with the medical practitioner responsible for your thyroid treatment.
Complementary care has a different role. It can focus on areas such as nutrition, dietary adequacy, digestive health, sleep, stress, fatigue and other individual concerns while appropriate medical thyroid treatment continues.
Complementary Thyroid Care
Can a Naturopath Help With Hypothyroidism?
Naturopathic care can provide complementary support for people with hypothyroidism by looking beyond the thyroid result alone and considering nutrition, symptoms, lifestyle and the broader health picture.
Review Diet & Nutritional Needs
We assess your usual diet, dietary restrictions, nutritional adequacy and other factors that may be relevant to energy, hair, digestive health and general wellbeing.
Look Beyond the Thyroid
Persistent fatigue, brain fog, digestive symptoms, sleep problems or women’s health concerns may deserve attention even when you already have a thyroid diagnosis.
Work Alongside Your Medical Care
Your GP or endocrinologist remains responsible for medical diagnosis, thyroid medication and monitoring. Our role is to provide complementary naturopathic and nutritional support.

Common Search Question
Can Hypothyroidism Go Away?
Whether hypothyroidism is temporary or long-term depends on the underlying cause.
Some forms of thyroid dysfunction may be temporary, while other causes, including autoimmune thyroid disease or reduced thyroid function following thyroid treatment or surgery, may require ongoing medical management.
This is why it is important to understand the cause of an underactive thyroid rather than relying on symptoms alone.
Why Monitoring Matters
What Happens if Hypothyroidism Is Left Untreated?
Persistent hypothyroidism can affect multiple areas of health. Appropriate diagnosis, treatment and follow-up help reduce the risk of complications and ensure thyroid hormone levels are monitored over time.
Energy & Daily Function
Untreated hypothyroidism may contribute to ongoing fatigue, reduced concentration, low mood, constipation and reduced quality of life.
Metabolic & Cardiovascular Health
Reduced thyroid function can influence metabolism and may be associated with changes in cholesterol and other cardiovascular risk factors.
Pregnancy & Reproductive Health
Appropriate thyroid management is particularly important during preconception and pregnancy, when thyroid hormone requirements may change.

Hypothyroidism Frequently Asked Questions
Clear answers to common questions about underactive thyroid symptoms, causes, testing, Hashimoto’s, weight gain, diet, fertility and complementary care.
What is hypothyroidism?
Hypothyroidism, also known as an underactive thyroid, occurs when the thyroid gland does not produce enough thyroid hormone for the body’s needs.
What are the main symptoms of an underactive thyroid?
Common symptoms may include fatigue, feeling cold, constipation, dry skin, hair changes, brain fog, changes in weight, low mood and muscle or joint symptoms.
What causes hypothyroidism?
Hypothyroidism can have several causes. Hashimoto’s thyroiditis is one common cause. Other causes may include previous thyroid treatment or surgery, some forms of thyroid inflammation, certain medicines and less common problems affecting thyroid hormone regulation.
Is Hashimoto’s the same as hypothyroidism?
No. Hashimoto’s is an autoimmune thyroid condition, while hypothyroidism describes reduced thyroid hormone production. Hashimoto’s can lead to hypothyroidism, but hypothyroidism can also have other causes.
How is hypothyroidism diagnosed?
Diagnosis usually involves medical assessment and thyroid blood tests. TSH and free T4 are commonly assessed, and thyroid antibodies may be considered where autoimmune thyroid disease is suspected.
What is subclinical hypothyroidism?
Subclinical hypothyroidism generally refers to a pattern where TSH is elevated but free T4 remains within the laboratory reference range. Management depends on the individual clinical situation.
Can hypothyroidism cause weight gain?
Hypothyroidism can contribute to changes in weight in some people because thyroid hormones influence metabolism. However, weight is also affected by diet, activity, sleep, hormones, medications and other health factors.
Can hypothyroidism cause hair loss?
Hair thinning or increased shedding can occur with reduced thyroid function. Hair loss can also have nutritional, hormonal, genetic, stress-related and other medical causes.
Why am I still tired even though I take thyroid medication?
Persistent fatigue can have multiple causes. Thyroid function may need review, but sleep, nutrition, iron status, stress, hormones and other medical conditions can also contribute.
Can hypothyroidism affect periods and fertility?
Thyroid dysfunction can be associated with menstrual and reproductive health changes. If you are trying to conceive and have known hypothyroidism, appropriate thyroid management and medical monitoring are important.
Is hypothyroidism important during pregnancy?
Yes. Adequate thyroid hormone is important during pregnancy, and people with diagnosed hypothyroidism may require closer thyroid monitoring and medication review by their medical practitioner.
What is the best diet for hypothyroidism?
There is no single diet that is right for everyone with hypothyroidism. A balanced, nutrient-dense eating pattern is a sensible foundation, while more specific dietary recommendations should be personalised to your individual health needs.
Should I avoid gluten if I have hypothyroidism?
Not automatically. People with coeliac disease need to avoid gluten, but a diagnosis of hypothyroidism alone does not mean everyone requires a gluten-free diet.
Should I take iodine for an underactive thyroid?
Do not assume that extra iodine is appropriate simply because you have hypothyroidism. Iodine is essential for thyroid hormone production, but excessive intake can also affect thyroid function. Supplementation should be individualised.
Can hypothyroidism go away?
It depends on the cause. Some forms of thyroid dysfunction may be temporary, while other causes may require long-term treatment and monitoring.
Can a naturopath help with hypothyroidism?
A naturopath can provide complementary support around nutrition, nutrient status, digestive health, sleep, stress, fatigue and lifestyle while appropriate medical thyroid treatment and monitoring continue.
Can naturopathic treatment replace thyroid medication?
No. If thyroid hormone replacement has been prescribed, do not stop, reduce or alter it without speaking with the medical practitioner responsible for your treatment.
Do you offer hypothyroidism consultations online?
Yes. Morkare Natural Clinic provides complementary thyroid naturopath consultations in Brisbane and via telehealth Australia-wide.
