Hyperthyroidism is a group of clinical syndrome caused by hyperplasia of thyroid gland, hyperfunction and excess produce and secretion of thyroid hormone.

  • Types of hyperthyroidism
  • Multinodular goiter
  • Plummer disease
  • Iodide hyperthyroidism
  • Pituitary hyperthyroidism
  • HCG (Human Chorionic Gonadotropin) related hyperthyroidism

Among them, the graves hyperthyroidism is the most common, accounting for 85% of all types of hyperthyroidism.

Clinical manifestation of hyperthyroidism

Clinically, hyperthyroidism patients mainly manifest as: palpitation, tachycardia, afraid of hot, sweating, polyphagia and marasmus (some people polyphagia but obesity), fatigue, weakness and emotional irritability, temperament, impatient, insomnia, unable to concentrate, prominent eyes, thyroid gland swelling, patients may have symptoms of muscular atrophy and weakness. Female patients may have symptoms of menstrual disorders or even amenorrhea, male patients may have symptoms of impotence or breast development. Thyroid enlargement is symmetrical, and a few patients are not symmetrical. Goiter may move up and down with swallowing, and there are also a part of hyperthyroidism patients have thyroid nodules.

There are two kinds of the ocular changes caused by hyperthyroidism, one is benign exophthalmos, patients’ eyes gaze or appear frightened, and another is malignant exophthalmos, which may change from the benign exophthalmos, patients often have symptoms of afraid of light, afraid of the wind, tears, diplopia, loss of vision, eye swelling and pain, tingling, and so on.

Diagnosis basis of hyperthyroidism

  1. Patients have typical symptoms and signs of hyperthyroidism.
  2. The uptake rate of iodine 131 increases (3 hours > 25%; 24 h > 45%), and the peak value appears in advance (the uptake rate of iodine 131 in 3 hours is 80% more than that in 24 hours), and T3 inhibition test is negative.
  3. Total thyroxine (TT4), total triiodothyronine (TT3), free thyroxine (FT4) and free triiodothyronine (FT3) increase. Thyroid-stimulating hormone (TSH) level decreases and is no response to the thyrotropin releasing hormone (TRH) stimulation test.
  4. Immunological test: the positive rate and titer of thyroid globulin antibody (TGAb) and thyroid microsomal antibody (TMAb) may increase, and the thyroid stimulating antibody (TSAb) is positive.

Hyperthyroidism patients also need to exercise

After the diagnosis of hyperthyroidism, patients should limit exercise in the earlier treatment, and pay attention to appropriate bed rest, so that to control the over fast heartbeat rate. And when condition is completely controlled, we believe that patients can do general physical exercise, and we also suggest patients should be appropriate to exercise more, so that patients’ physical quality can be improved, and patients can reduce the risk of hyperthyroidism crisis. Meanwhile, pay attention to the amount of exercise, when patients feel flustered obvious, they should immediately stop exercise and have a rest, don’t try to play rough. Patients can play sports such as bicycle sports, running, swimming, mountain climbing and so on with the conditions of their body allowing.
