Thyroid Problems in Women: Symptoms, Tests and Treatment

The thyroid is a small, butterfly-shaped gland in the front of your neck, but it has a big job: it makes hormones that control how fast your body uses energy. When it makes too little or too much hormone, almost every system — weight, heart rate, mood, periods and fertility — can be thrown off. Thyroid problems are common in Bangladesh and affect women far more than men, yet they are often mistaken for ordinary tiredness or stress.

Why are women more likely to have thyroid problems?

Women are roughly five to eight times more likely than men to develop thyroid disease, largely because of autoimmune conditions that target the gland and the hormonal shifts of menstruation, pregnancy and menopause. Pregnancy and the months after delivery are especially common times for thyroid trouble to appear. This is why doctors pay close attention to thyroid health in women. A personal or family history of autoimmune disease further raises the risk.

What are the symptoms of an underactive thyroid (hypothyroidism)?

An underactive thyroid slows the body down, and the symptoms often build up so gradually that they are easy to ignore. Common signs include:

• Weight gain despite no change in diet
• Feeling cold when others are comfortable
• Tiredness, sluggishness and low mood
• Dry skin and hair fall
• Constipation
• Irregular or heavy periods, and difficulty getting pregnant

What about an overactive thyroid (hyperthyroidism)?

An overactive thyroid speeds everything up, so people may notice the opposite pattern — and these symptoms can feel alarming.

• Weight loss despite a good appetite
• A fast or pounding heartbeat (palpitations)
• Feeling hot and sweating easily
• Anxiety, restlessness and shaky hands
• Trouble sleeping
• Loose or frequent stools

How are thyroid problems tested?

A simple blood test for TSH (thyroid-stimulating hormone), often with free T4 (FT4), tells your doctor whether the gland is underactive or overactive. These tests are cheap and widely available across Bangladesh. Thyroid testing is especially important in pregnancy, because untreated thyroid disease can harm both mother and baby, so many doctors check it early. If a result is borderline, your doctor may repeat it later or add a thyroid antibody test to find the cause, and a family history of thyroid disease is worth mentioning.

How are thyroid problems treated?

Most cases are very manageable. An underactive thyroid is usually treated with a daily levothyroxine tablet — available from any licensed pharmacy or the medicine directory — best taken on an empty stomach with water about 30–60 minutes before breakfast, with other foods and medicines kept apart from it. This treatment is often lifelong but allows a completely normal life when the dose is correct. After starting treatment, your doctor will recheck your TSH every few weeks at first and then less often once it is stable, and symptoms usually ease gradually over weeks rather than overnight. An overactive thyroid is treated differently, with medicines or other options your doctor will explain. Build a goitre-prevention habit too: cook with iodised salt, which protects the gland. Never adjust your own dose — it must be guided by repeat blood tests and your doctor.

When should you see a doctor?

See a doctor if you have unexplained weight change, a constantly racing heart, ongoing fatigue, hair fall, irregular periods, trouble conceiving, or a visible swelling in the neck (goitre). Do not believe myths that thyroid disease cannot be treated or that it always causes infertility — with the right care, most women lead full, healthy lives, including healthy pregnancies. Babies and older adults can show unusual or subtle signs, so testing is worthwhile whenever something seems off. You can book a verified doctor on ChamberBD for testing and a treatment plan that suits you.
