What are the Most Common Thyroid Disorders?

Thyroid disorders can impact anyone at any age. Although most common in people over the age of 60, thyroid disorders can appear in adult men and women, teenagers, children, infants, and the elderly. Dr. Alexander Haug is a respected thyroid disease specialist located in Vienna. In this blog post, Dr. Alexander Haug and his team provide important information on the most common thyroid disorders. If you are experiencing any of the below symptoms, please consult with a medical professional for advice.


Hyperthyroidism is caused by an overactive thyroid gland. It is a condition where your body produces too much thyroid hormone. This results in an increased heart rate, nervousness, difficulty sleeping, brittle hair and nails, weight loss, muscle weakness, and more frequent bowel movements. People with hyperthyroidism may also be irritable, sweat more, and experience feelings of anxiety.

Your doctor can diagnose hyperthyroidism and prescribe medication to keep the condition under control.


Conversely, hypothyroidism is a condition where the thyroid gland is not producing enough hormne. People who have had their thyroid removed, have an iodine deficiency, or are on certain types of medications can experience hypothyroidism. It is also seen in people with type 1 or 2 diabetes, celiac disease, rheumatoid arthritis, or lupus.

Generally, hypothyroidism is a mild condition. Symptoms include being more sensitive to cold, memory issues, constipation, weight gain, depression, fertility problems, fatigue, muscle weakness and joint pain. In extreme cases, hypothyroidism can result in a person falling into a coma.

Blood tests and imaging tests are used to diagnose hypothyroidism. The condition is treated with thyroid hormone pills.

Hashimoto’s Thyroiditis

Also called chronic lymphocytic thyroiditis, Hashimoto’s thyroiditis is a common cause of hypothyroidism. It is most commonly seen in young and middle-aged women. Hashimoto’s thyroiditis occurs when the body mistakenly starts to attack the thyroid gland. Fatigue, depression, weight gain, thin hair, constipation, and an enlarged goitre are all symptoms of Hashimoto’s thyroiditis.

This condition is diagnosed by blood tests and ultrasound and treated with hormone-replacing medication.
