This article covers the most common thyroid problems, the symptoms that signal each one, which complications can develop if they’re left untreated, and when you should see a specialist. If you’re dealing with unexplained symptoms or have been told you have a thyroid nodule, this will help you understand what’s happening and what your options are.
Key Takeaways
- If you’re constantly tired, gaining weight for no clear reason, and freezing when nobody else is, get your thyroid checked. Hypothyroidism is the most common thyroid disorder in India and these are its calling cards.
- Hyperthyroidism does the opposite. Racing heart, unexplained weight loss, shaky hands, and feeling wired all the time. Your body is running too fast.
- Thyroid nodules are common and usually harmless. But “usually” isn’t “always,” so any lump in the neck needs an ultrasound at minimum.
- Ignore a thyroid problem long enough and it can damage your heart, your bones, and your ability to have children.
- Dr. Gaurav Gangwani treats thyroid nodules in Mumbai without surgery, using radiofrequency and microwave ablation. No scar, no general anaesthesia, and most patients go home the same day.
What Happens When Your Thyroid Produces Too Little Hormone?
Your thyroid is a small, butterfly-shaped gland at the front of your neck, and it controls more than most people realise. Metabolism, heart rate, body temperature, energy levels, weight, mood, and digestion. When the thyroid produces too much or too little hormone, the effects ripple across your entire body. According to data published in the Indian Journal of Endocrinology and Metabolism, an estimated 42 million people in India suffer from thyroid disorders. Women are affected far more than men, and many cases go undiagnosed for years because symptoms overlap with everyday complaints like fatigue or weight gain. Understanding what can go wrong is the first step toward catching problems early.
Hypothyroidism occurs when the thyroid doesn’t produce enough T3 and T4 hormones. Your metabolism slows, and your body’s systems start operating at reduced capacity. A population-based study from Cochin found hypothyroidism prevalence in Indian adults at 3.9%, with subclinical hypothyroidism at 9.4%. In women, it reached 11.4%.
The symptoms build gradually, which is why people dismiss them. Persistent fatigue that doesn’t improve with rest. Unexplained weight gain. Feeling cold when everyone else is comfortable. Dry skin, thinning hair, constipation. Depression and difficulty concentrating. Heavier menstrual periods in women.
Hashimoto’s thyroiditis, an autoimmune condition where the immune system attacks the thyroid gland, is the most common cause in India’s post-iodisation era. Left untreated, hypothyroidism can raise cholesterol, increase heart disease risk, and in pregnant women, affect foetal brain development.
What Problems Does an Overactive Thyroid Cause?
Hyperthyroidism is the opposite. The thyroid overproduces hormones and everything speeds up. Rapid or irregular heartbeat, unintended weight loss, anxiety, trembling hands, excessive sweating, difficulty sleeping, and frequent bowel movements.
Graves’ disease, another autoimmune condition, is the most common cause. It can also cause a distinctive eye condition where the eyes bulge forward.
Untreated hyperthyroidism strains the heart. It can lead to atrial fibrillation (increasing stroke risk), weakened bones, and in extreme cases, a thyroid storm requiring emergency care.
What Are Thyroid Nodules and Should You Be Worried?
Thyroid nodules are solid or fluid-filled lumps inside the gland. They’re extremely common and often discovered incidentally during scans done for other reasons.
Most are benign. But roughly 5 to 15% turn out to be cancerous, which is why any nodule needs evaluation with ultrasound and sometimes a fine needle biopsy.
Larger benign nodules can press against the windpipe or oesophagus, making it hard to swallow or breathe. Some produce excess thyroid hormone independently, causing hyperthyroid symptoms.
Traditionally, problematic nodules meant surgery: removing part or all of the thyroid, general anaesthesia, a visible scar, and lifelong hormone replacement. Dr. Gaurav Gangwani offers a different path. He specialises in microwave ablation and radiofrequency ablation, where targeted heat delivered through a thin needle under ultrasound guidance shrinks the nodule without removing the gland. Local anaesthesia, no scar, and most patients return to normal activity within a day or two.
How Do Thyroid Problems Affect Women Differently?
Women are five to eight times more likely to develop thyroid disorders. The connection to reproductive health is significant. Thyroid dysfunction can cause irregular periods, difficulty conceiving, and pregnancy complications.
Untreated hypothyroidism in pregnancy increases the risk of miscarriage, pre-eclampsia, premature delivery, and impaired foetal brain development. Thyroid conditions can also mimic menopause symptoms, making diagnosis harder for women in their 40s and 50s.
When Should You See a Specialist About Your Thyroid?
A simple blood test measuring TSH and T3/T4 levels can identify most thyroid disorders. But knowing when to get tested is where many people fall behind.
See a doctor if you’re experiencing unexplained weight changes, persistent fatigue, changes in heart rate, swelling or a lump at the front of your neck, difficulty swallowing, or menstrual irregularities.
If you’ve been diagnosed with a thyroid nodule or goitre, seek a specialist who can evaluate whether monitoring, medication, or intervention is the right path. Dr. Gangwani’s Vascular Clinic in Borivali, Mumbai offers comprehensive thyroid evaluation including ultrasound-guided assessment and minimally invasive treatment for nodules. His approach prioritises preserving the thyroid gland wherever possible, helping most patients avoid surgery.
Frequently Asked Questions
1. Can thyroid problems develop at any age?
At any age, yes. Even newborns. Risk climbs after 40, especially for women.
2. Are thyroid nodules always cancerous?
No. Roughly 85 to 95% are benign. An ultrasound and biopsy confirm what you’re dealing with. Most people worry for nothing, but getting checked is still important.
3. Can thyroid problems cause hair loss?
They can. Hypothyroidism makes hair dry and brittle. Hyperthyroidism thins it out. It usually grows back once levels stabilise.
4. Is surgery the only option for thyroid nodules?
Dr. Gangwani uses radiofrequency and microwave ablation to shrink nodules without removing the gland. No scar, no general anaesthesia.
5. How often should I get my thyroid checked?
Every few years if you’re symptom-free. Annually if you have family history or you’re a woman over 35.
