Signs of Thyroid Problems: How Do You Know If You Have Them?
The thyroid may be a small gland, but it has an important role in your overall health. It produces hormones that help regulate metabolism, energy use, body temperature, heart rate and several other body functions.
When the thyroid produces too little or too much hormone, it can lead to a range of symptoms. The problem is that many signs of thyroid problems can look like everyday issues such as stress, poor sleep, nutritional deficiencies or hormonal changes.
So, how do you know if your symptoms could be related to your thyroid? In this article, we'll look at the common signs of thyroid issues, the differences between an underactive and overactive thyroid, when you should consider thyroid testing, and how lifestyle and Ayurvedic wellness approaches may support your overall thyroid health.
10 Common Signs of Thyroid Problems
Not everyone with a thyroid disorder experiences the same symptoms. However, certain changes may indicate that it is worth discussing thyroid health with a healthcare professional.
1. Unexplained Weight Changes
Unexpected changes in body weight are one of the commonly noticed signs of thyroid issues.
An underactive thyroid may be associated with weight gain, while an overactive thyroid may contribute to unintentional weight loss.
However, weight changes can occur for many reasons, including changes in diet, physical activity, sleep, stress, medications and other health conditions.
If your weight is changing without an obvious explanation, it is worth discussing the change with a healthcare professional rather than assuming that your thyroid is responsible.

2. Constant Tiredness or Low Energy
Do you feel tired even after getting what seems like enough sleep?
Persistent fatigue can occur with hypothyroidism because the body's processes may slow down when thyroid hormone levels are low.
Some people may describe this as:
- Low energy
- Feeling sluggish
- Difficulty staying active
- Needing more rest than usual
- Difficulty concentrating
Fatigue is not specific to thyroid disease, however. Poor sleep, stress, anaemia, nutritional deficiencies and other conditions can also cause persistent tiredness.
3. Feeling Too Cold or Too Hot
Changes in your sensitivity to temperature can sometimes be associated with thyroid problems. People with an underactive thyroid may feel unusually cold, while people with an overactive thyroid may experience heat intolerance or excessive sweating.
If you regularly feel much colder or hotter than people around you without an obvious environmental reason, consider discussing it with your doctor.
4. Hair Loss or Thinning Hair
Changes in thyroid hormone levels may affect the normal hair-growth cycle.
Some people with thyroid problems may notice:
- Increased hair shedding
- Thinning hair
- Dry or brittle hair
- Changes in hair texture
Hair loss can have numerous causes, including nutritional deficiencies, hormonal changes, stress and certain medications.
Therefore, persistent or sudden hair loss deserves proper evaluation rather than being automatically attributed to thyroid problems.

5. Changes in Your Heart Rate
Your thyroid hormones can influence cardiovascular function.
An overactive thyroid may be associated with:
- Fast heartbeat
- Palpitations
- Increased awareness of your heartbeat
An underactive thyroid may be associated with a slower heart rate.
If you experience persistent palpitations, an unusually rapid heartbeat, chest discomfort, fainting or shortness of breath, seek medical attention promptly.
6. Mood and Concentration Changes
Thyroid problems can sometimes affect mood and cognitive function.
Hypothyroidism may be associated with:
- Low mood
- Difficulty concentrating
- Slower thinking
- Feeling mentally tired
Hyperthyroidism may be associated with:
- Anxiety
- Nervousness
- Irritability
- Restlessness
- Difficulty sleeping
These symptoms can also occur because of stress, lifestyle factors and other conditions, so they should be considered alongside other symptoms.
7. Changes in Bowel Habits
Your thyroid influences metabolism and many body processes, including digestive function.
An underactive thyroid may be associated with constipation, while an overactive thyroid can sometimes cause more frequent bowel movements or diarrhoea.
Persistent changes in bowel habits should not automatically be blamed on the thyroid. Your diet, hydration, medications and digestive health can also play a role.
8. Changes in Menstrual Cycle
Thyroid hormones can interact with reproductive and hormonal systems.
Some women with thyroid disorders may experience changes such as:
- Heavier or lighter periods
- Irregular periods
- Changes in cycle length
- Other menstrual changes
Because menstrual changes can have many causes, including pregnancy, PCOS, stress and other hormonal conditions, medical evaluation can help identify the underlying reason.
9. Dry Skin and Changes in Appearance
Dry or rough skin can sometimes occur with hypothyroidism. Some people may also notice changes in their nails, hair or general skin texture. However, dry skin is extremely common and can result from weather, dehydration, skincare products and other factors.
When combined with other symptoms such as fatigue, weight gain, constipation or cold sensitivity, it may be worth discussing thyroid testing with a healthcare professional.
10. Swelling or a Lump in the Neck
A visible swelling or lump around the thyroid area may indicate an enlarged thyroid, also known as a goitre, or a thyroid nodule.
Not every thyroid nodule causes abnormal thyroid hormone levels, and many thyroid nodules are not cancerous. However, any new or persistent lump or swelling in the neck should be evaluated by a healthcare professional.
Signs of an Underactive Thyroid
An underactive thyroid, or hypothyroidism, may cause symptoms because the body is not receiving enough thyroid hormone.
Common signs can include:
- Fatigue
- Weight gain
- Feeling cold
- Dry skin
- Hair thinning
- Constipation
- Low mood
- Difficulty concentrating
- Muscle weakness
- Slower heart rate
- Menstrual changes
Symptoms can develop gradually, so some people may not realise that anything has changed until several symptoms appear together.

Signs of an Overactive Thyroid
An overactive thyroid, or hyperthyroidism, produces a different pattern of symptoms.
These may include:
- Unintentional weight loss
- Increased appetite
- Rapid heartbeat
- Palpitations
- Anxiety or nervousness
- Trembling
- Excessive sweating
- Heat intolerance
- Difficulty sleeping
- Muscle weakness
- More frequent bowel movements
If you experience significant heart-related symptoms, seek medical evaluation rather than attempting to manage them with supplements alone.
How Do You Know If You Have a Thyroid Problem?
Symptoms can give you a reason to investigate, but you cannot confirm a thyroid disorder based on symptoms alone. A healthcare professional may consider your symptoms, medical history and family history and recommend thyroid function testing.
Common tests include:
TSH - Thyroid-stimulating hormone (TSH) is commonly used to assess thyroid function.
Free T4 - Free T4 can help assess the amount of available thyroxine in the blood.
T3 - T3 testing may sometimes be useful, particularly when hyperthyroidism is suspected.
Thyroid antibody tests - When an autoimmune thyroid condition is suspected, specific antibody tests may be recommended.
Depending on your symptoms and examination, your doctor may recommend additional tests, such as thyroid ultrasound.
Final Thoughts
Thyroid problems can sometimes develop slowly, and their symptoms may be easy to dismiss as stress, ageing, poor sleep or everyday tiredness.
If you notice several symptoms together particularly unexplained weight changes, persistent fatigue, temperature sensitivity, hair changes, menstrual changes or heart-rate changes it may be worth discussing thyroid health with a healthcare professional.
A simple conversation and appropriate testing can help determine whether your thyroid is functioning normally. If you already have a diagnosed thyroid condition, continue your recommended treatment and monitoring.
