Thyroid Disorders
The thyroid is a small gland with a wide reach — influencing energy, weight, mood, heart rate and more. When it's over- or under-active, the effects can be far-reaching, and expert diagnosis makes all the difference. Personalised care from consultant endocrinologist Dr Sheharyar Qureshi.

01 — UNDERSTANDING THE GLAND
What does the thyroid do?
The thyroid is a small, butterfly-shaped gland at the front of the neck. It produces hormones — chiefly thyroxine (T4) and triiodothyronine (T3) — that regulate metabolism: the rate at which the body uses energy. These hormones influence almost every organ, affecting heart rate, body temperature, weight, digestion, mood and energy levels.
The thyroid's output is controlled by the pituitary gland, which releases thyroid-stimulating hormone (TSH). This feedback loop keeps hormone levels balanced. When the balance is disturbed — the gland producing too much or too little hormone — the effects can be felt throughout the body, which is why thyroid symptoms are so varied.
Thyroid disorders are common, particularly in women, and can develop gradually. Because the symptoms are easily attributed to other causes, they are sometimes overlooked. A simple set of blood tests, interpreted by a specialist, usually gives a clear picture.
02 — THE TWO MAIN PATTERNS
Underactive & overactive thyroid
Most thyroid disorders fall into one of two broad categories, depending on whether the gland is producing too little or too much hormone.
Hypothyroidism
The body's processes slow down. It's the more common of the two, and is often caused by Hashimoto's, an autoimmune condition in which the immune system gradually reduces the gland's function.
UNDERACTIVE
Too little thyroid hormone
COMMON SYMPTOMS
-
Tiredness and low energy
-
Weight gain and feeling the cold
-
Dry skin, hair thinning, constipation
-
Low mood and slowed thinking
Hyperthyroidism
The body's processes speed up. A frequent cause is Graves' disease, an autoimmune condition that overstimulates the gland. Thyroid nodules can also produce excess hormone.
OVERACTIVE
Too much thyroid hormone
COMMON SYMPTOMS
-
Weight loss despite normal appetite
-
Rapid heartbeat and palpitations
-
Anxiety, irritability, tremor
-
Sweating and sensitivity to heat
03 — BEYOND OVER- AND UNDERACTIVE
Other thyroid conditions we treat
Thyroid health involves more than hormone levels alone. We assess and manage the full range of thyroid conditions, including structural changes to the gland.
Thyroid nodules
Lumps within the gland, which are common and usually benign, but warrant assessment to confirm.
Goitre
An enlarged thyroid gland, which may or may not affect hormone levels and can have several causes.
Hashimoto's thyroiditis
The most common autoimmune cause of an underactive thyroid, often developing slowly over time.
Graves' disease
An autoimmune cause of an overactive thyroid, sometimes affecting the eyes as well.
Thyroid in pregnancy
Careful management of thyroid function before and during pregnancy, when balance is especially important.
Subclinical thyroid disease
Borderline results that need expert interpretation to decide whether and when to treat.
04 — DIAGNOSIS
How thyroid disorders are diagnosed
Thyroid conditions are usually straightforward to identify with the right tests — but interpreting them correctly, and knowing when borderline results need action, is where specialist expertise matters.
Detailed consultation
A full review of your symptoms, medical and family history, medications and any neck changes, alongside an examination of the gland.
