Hyperthyroidism is a condition where the thyroid gland, a small gland located in the neck, produces too much thyroid hormone. This can lead to a variety of symptoms, many of which are well-known, such as weight loss, rapid heart rate, and tremors. However, there are several surprising symptoms of hyperthyroidism that are less well-known but equally important to recognize. In this blog, we’ll discuss 8 surprising symptoms of hyperthyroidism that you should never ignore.

  1. Heat intolerance
    One of the lesser-known symptoms of hyperthyroidism is heat intolerance. People with hyperthyroidism often feel hot and sweaty, even in cool temperatures. This is because the excess thyroid hormone in their system speeds up their metabolism, which raises their body temperature.
  2. Mood swings
    Hyperthyroidism can cause a range of mood swings, including anxiety, irritability, and even depression. These changes in mood can be particularly frustrating because they may not have an obvious cause and can come on suddenly.
  3. Irregular periods
    For women, hyperthyroidism can cause irregular periods, heavy periods, or even missed periods. This is because the excess thyroid hormone can disrupt the delicate balance of hormones needed for the menstrual cycle.
  4. Muscle weakness
    Hyperthyroidism can cause muscle weakness, particularly in the arms and legs. This can make everyday activities such as climbing stairs or lifting objects difficult.
  5. Insomnia
    Many people with hyperthyroidism find it difficult to sleep, even when they are tired. This is because the excess thyroid hormone in their system can cause restlessness and anxiety, making it difficult to fall and stay asleep.
  6. Eye problems
    Hyperthyroidism can cause eye problems, particularly in people with a condition known as Graves’ disease. This can include bulging eyes, eye pain, double vision, and even vision loss in severe cases.
  7. Hair loss
    Excess thyroid hormone can cause hair loss, particularly from the scalp, eyebrows, and eyelashes. This can be particularly distressing for people who are already dealing with the other symptoms of hyperthyroidism.
  8. Increased appetite
    While weight loss is a well-known symptom of hyperthyroidism, many people are surprised to learn that the condition can also cause an increased appetite. This is because the excess thyroid hormone in the system can increase the body’s metabolism, making people feel hungry more often.

In conclusion, hyperthyroidism is a complex condition that can cause a wide range of symptoms. While some symptoms such as weight loss and rapid heart rate are well-known, others such as heat intolerance, mood swings, irregular periods, muscle weakness, insomnia, eye problems, hair loss, and increased appetite are less well-known but equally important to recognize. If you are experiencing any of these symptoms, it’s important to talk to your doctor as soon as possible to get an accurate diagnosis and start treatment if necessary.
