Hyperthyroidism
  • Hyperthyroidism is a health condition where the
    thyroid gland is overactive and produces large
    amount of the hormone thyroxine. The thyroid
    gland is situated at the front of the neck and
    releases hormones that control the bodys
    metabolism. When a patient is suffering from
    hyperthyroidism, his/her metabolism rate shoots
    up indefinitely causing irregular heartbeat,
    sudden weight loss, nervousness,
    sweating, sleeping issues and more. Hyperthyroid
    ism can create other health complications which
    often make it difficult for the doctor to
    diagnose.

Causes of Hyperthyroidism
  • The thyroid gland produces (T3) triiodothyronine
    and (T4) thyroxine hormones which control most of
    the body functions. If the gland makes too much
    of T3 and T4 hormones, it is definitely
    hyperthyroidism. One of the common and prime
    causes of hyperthyroidism is the autoimmune
    disorder Graves disease. In this disease, the
    body produces an antibody called
    thyroid-stimulating immunoglobulin (TSI) which
    causes the thyroid gland to release excessive
    amount of thyroid hormone. Graves disease
    usually runs in families and found more active on
    women. Another reason for hyperthyroidism is a
    multinodular goiter. These are lumps in the
    thyroid gland that cause the thyroid to make too
    much thyroid hormone. Additionally, swelling of
    the thyroid gland- known as thyroiditis-
    resulting from an immune problem may also
    temporarily cause hyperthyroidism. Furthermore,
    too much iodine intake in the form of food or
    medication can also trigger the symptoms of
    hyperthyroidism.

Diagnosis of hyperthyroidism
  • Hyperthyroidism is diagnosed by analyzing
    symptoms and based on them endocrinologists
    conduct physical exam and blood test to assess
    levels of thyroid stimulating hormone (TSH) and
    thyroid hormones T3 and T4. He may perform an
    ultrasound to check the thyroid for inflammation.

Symptoms
  • It can cause a range of signs and symptoms 
  • Even if your appetite and food intake remain the
    same, you may experience sudden weight loss 
  • Irregular heartbeat, mainly 100 beats per minute 
  • Muscular weakness or tiredness 
  • Anxiety or nervousness 
  • Changes in bowel movements 
  • Dry skin 
  • Irregular periods or missed periods 
  • Increased intoleration to heat 
  • Dizziness 
  • Goiter, which may appear as an inflammation at
    the bottom of the neck 
  • Problems with fertility 
  • Changes in vision

Treatments
  • Various treatment options are available today if
    you have hyperthyroidism. Endocrinologists use
    anti-thyroid medications that prevent the thyroid
    gland from producing excess amounts of hormones.
    Another way to treat hyperthyroidism is to give
    patients radioactive iodine therapy, wherein they
    are asked to take radioactive iodine in the form
    of medication. The treatment is absolutely safe
    and it slows down the thyroid activity
    considerably. The medicine is usually taken on a
    daily basis. For pregnant women who are unable
    to withstand anti-thyroid drugs and radioactive
    iodine therapy, the only option is surgical
    removal of the thyroid. In some cases,
    endocrinologists also prescribe beta-blockers
    which block the effects of thyroid hormones.
