Symptoms Symptoms of hypothyroidismHypothyroidism - underactive thyroid may include fatigue, daytime sleepiness, weight gain, water retention, thinning hair, dry skin, constipation, difficulty concentrating, and others.

Hypothyroidism can range from mild forms that are asymptomatic, and found only via blood tests, to severe hypothyroidism, that is associated with significant symptoms along with abnormal lab results. Diagnosis The diagnosis of hypothyroidismHypothyroidism - underactive thyroid is achieved through a careful history and physical examination.

Except in cases of longstanding significant hypothyroidism, physical examination will usually not provide any clues to the presence of the disease. The thyroid itself may feel normal. The hormone that causes the thyroid to make and release thyroid hormone level is the best test for diagnosing hypothyroidism.

A high TSH level confirms the diagnosis of hypothyroidism in most patients. Typically, the free T4 level is usually low. Common causes HypothyroidismHypothyroidism - underactive thyroid is most commonly caused by an underlying thyroid disease i.

The hormone that causes the thyroid to make and release thyroid hormone production i. The most common causes of primary hypothyroidism are autoimmune thyroiditis i. These antibodies cause destruction of thyroid cells which leads to fewer cells making thyroid hormone.

Thyroidectomy Removing the whole thyroid will cause hypothyroidism unless the patient is given thyroid hormone replacement postoperatively. In patients who have less than the whole thyroid removed i. Even patients who have only had half the thyroid removed are at a higher risk of developing hypothyroidism than the general public.

The higher the dose, the greater the chance of developing hypothyroidism.

However, even smaller doses can lead to hypothyroidism, just over a longer time period. Of note, diagnostic radioactive thyroid scans do NOT lead to hypothyroidism. Abnormal iodine intake Abnormal iodine intake can lead to hypothyroidism.

Epidemiology and aetiology

The major building block of thyroid hormone is iodine, and therefore not enough iodine in the diet can lead to hypothyroidism. Inadequate iodine intake is rare in North America and most of Europe due to the use of iodized salt.Hyperthyroidism is a pathological disorder in which excess thyroid hormone is synthesised and secreted by the thyroid gland.

It is characterised by normal or high thyroid radioactive iodine uptake (thyrotoxicosis with hyperthyroidism or true hyperthyroidism). Graves’ disease is the most common cause of hyperthyroidism, a disorder that causes the thyroid to produce too much thyroid hormone.
