Hashimoto's disease is an autoimmune condition that affects the thyroid gland. Often patients with Hashimoto's go through a phase in which the thyroid gland is overactive due to an initial release of thyroid hormone in a period of acute inflammation. Over time, however, as the thyroid gland is slowly destroyed by the body's immune cells, the thyroid gland becomes underactive. People with underactive thyroid gland (hypothyroidism) can experience a range of symptoms, including weight gain, constipation, cold intolerance, muscle weakness/cramping and an irregular menstrual cycle.
Another complication of hypothyroidism is fatigue, both mental and physical. Patients may notice that they are not thinking as clearly as they did prior to developing thyroid dysfunction. Theoretically, this could manifest as new difficulty with reading and writing as your ability to concentrate and focus is diminished. However, thyroid disease is not the only cause of these symptoms, and depression
should also be considered as a possible culprit if your thyroid levels are found to be normal.
Since the cause of your symptoms is unclear, it is advisable that you seek out the help of your primary care physician
. A simple blood test can help determine if your thyroid gland is acting appropriately.
