The thyroid gland, situated in the neck, may seem relatively small, but its role in maintaining overall health cannot be overlooked. The thyroid acts as the body's metabolic regulator. It releases hormones and what this means is that it directly influences how the body consumes energy, metabolizes nutrients, and regulates temperature. This organ contributes significantly to brain function and cognitive abilities. It is essential for memory, concentration, and mood regulation.
Overview of Thyroid Health
The thyroid is a gland located in the front of the neck, underneath the skin. The butterfly-shaped thyroid gland has a very important job, as it regulates the function of the metabolism. As part of the endocrine system, the thyroid hormones must be perfectly balanced at all times for the body to function normally. Even a small imbalance can lead to thyroid problems, including hyperthyroidism or hypothyroidism.

What are the signs that my thyroid may not be working properly?
Thyroid problems can affect many areas of the body.
Symptoms may include:
Underactive thyroid (hypothyroidism)
Possible symptoms:
- Fatigue
- Feeling unusually cold
- Weight gain
- Dry skin
- Constipation
- Low energy
Overactive thyroid (hyperthyroidism)
Possible symptoms:
- Unexplained weight loss

Symptoms can overlap with other health conditions, so medical assessment is important for accurate diagnosis.
Can thyroid nodules affect thyroid health?
Thyroid nodules are lumps that develop within the thyroid gland.
Many thyroid nodules are benign and do not cause symptoms.
However, some nodules may require further assessment to determine:
- Whether they affect thyroid function
- Whether they are growing
- Whether treatment is needed
Assessment may involve:
- Physical examination
- Thyroid blood tests
- Ultrasound imaging
- Biopsy when appropriate
Understanding the characteristics of a thyroid nodule helps guide whether monitoring or treatment is recommended.
Warning Signs and Symptoms of Thyroid
Warning signs will alert you of thyroid malfunction, which could indicate either hypothyroidism or hyperthyroidism. Here are just some of the many symptoms to look out for:
- Weight gain or weight loss
- Brittle hair
- Frequently feeling cold (or hot)
- Chronic fatigue
- Hair loss
- Irregular menstrual cycles
- Heat intolerance
- Enlarged thyroid gland or goiter
Thyroid-Healthy Nutrition and Diet
Many people fail to realize the importance of nutrition on their overall health, including the functioning of their thyroids. Food and nutrition can have a major impact on thyroid function, which is why following a balanced diet full of fruit, vegetables, lean meats, healthy fats, and whole grains is essential for overall health. Many people experience thyroid symptoms because they're deficient in the important nutrient iodine so following a thyroid diet is a good idea. If you're wondering how to keep a healthy thyroid, including iodine-rich foods in the diet like seaweed, baked potatoes (with skin) eggs, dairy, cod, and more in your diet, is a good idea. These are considered "thyroid prevention foods."
Supplements
Many people experiencing thyroid dysfunction can benefit from taking certain supplements for thyroid health. Some supplements for thyroid health that people may want to try are vitamin D, selenium, zinc, iodine, and more. Some supplement manufacturers even make supplements containing multiple thyroid-regulating ingredients in one product. It's a good idea to see your doctor before self-medicating with supplements, as you could do more harm than good if you take the wrong products.
Avoid Environmental Toxins
There are several potentially harmful environmental toxins to avoid, as they can negatively impact your entire body, including thyroid function. Many harmful environmental poisons are considered to be endocrine disruptors. An endocrine disruptor is defined as any chemical with the ability to impede the normal functioning of the endocrine and reproductive systems, which work in conjunction with one another. These toxins are in cleaning products, personal care products, pesticides, and more. It can seem impossible to avoid these chemicals, which are sometimes carcinogenic, but with effort it's possible.
Some ways to minimize exposure to these potentially hazardous toxins are:
- Limit your use of plastic and use glass instead whenever possible. Many plastics contain Bisphenol A (BPA), a known endocrine disruptor.
- Refrain from using non-stick cookware and use stainless steel instead, which is safer.
- Avoid anti-bacterial soaps and other cleaning products.
- Try to consume as many organic foods as possible, especially produce, as non-organic produce is treated with pesticides and other chemicals that can be harmful to your thyroid gland.
- Use a high-quality water filter for both drinking and bathing, to filter out dangerous chemicals like lead, nitrogen, and more.
Annual Physical Exam
Since symptoms of thyroid disease can sometimes be vague or mistaken for other conditions, it's a good idea to see your doctor for an annual physical exam. During an annual physical exam, your doctor will likely order routine blood tests, including tests to ensure your thyroid is functioning within normal parameters. During physical exams is often when people discover that their thyroid functioning has gone south, and some even discover that they have thyroid nodules.
When You Experience These Symptoms, Consult a Thyroid Nodule Specialist
Again, there are a number of symptoms that can be experienced by people with thyroid disease that may involve thyroid nodules. Thyroid nodules are abnormal lumps (growths) within the thyroid gland, a butterfly shaped gland in the neck just below the voice box. This is a very common condition seen in approximately 30% of adults. These are more commonly seen in females. There can be single or multiple thyroid nodules. If you experience symptoms of thyroid nodules, you should schedule an appointment and you might even want to consider seeing our thyroid specialist in Singapore, Dr. Manish Taneja. Our expert has specialised experience in promoting a healthy thyroid and minimally invasive treatments, especially thyroid nodule radiofrequency ablation.
