About Hypothyroidism :
Hypothyroidism causes the thyroid gland to not make enough thyroid hormone. Hypothyroidism is most common in older women. Thyroid function tests are available to diagnose hypothyroidism.
Hypothyroidism Symptoms :
Symptoms of hypothyroidism vary depending on the severity of the hormone deficiency. Often these problems develop slowly over many years.
Symptoms of hypothyroidism include -
• Tiredness
• Increased sensitivity to cold
• Constipation
• Dry skin
• Weight gain
• Swollen face
• Hoarseness
• High blood cholesterol
• Muscle weakness
• Muscle pain
• Joint pain swelling or stiffness
• Heavier than normal or irregular periods
• Hair loss
• Enlargement of thyroid gland
• Slow heart rate
• Depression
• Impaired memory
Hypothyroidism Cause :
When the thyroid gland does not make enough thyroid hormone, the balance of chemical reactions in the body can be disturbed. Hyperthyroidism can be caused by treatment, autoimmune disease, radiation therapy, thyroid surgery, and certain medications.
The thyroid is a small butterfly-shaped gland at the base of the front of your neck. Triiodothyronine (T3) and thyroxine (T4) – Hormones produced by the thyroid gland have a huge impact on health.
Hypothyroidism occurs when the thyroid gland fails to produce enough hormones. There are many causes of hypothyroidism. As if -
Autoimmune Diseases -
An autoimmune disorder is the most common cause of hypothyroidism. Autoimmune disorders occur when the immune system produces antibodies that attack your own tissues. Sometimes your thyroid gland is involved in this process.
Over-reaction to Hyperthyroidism Treatment -
People who produce too much thyroid hormone (hyperthyroidism) are treated with radioactive iodine or anti-thyroid drugs.
Thyroid Surgery -
Removal of part or all of your thyroid gland stops or reduces hormone production. In such a situation, you would have to take thyroid hormone for the rest of your life.
Radiation Therapy -
Radiation used to treat neck and head cancers can affect the thyroid gland, which can lead to hypothyroidism.
Medicines -
Certain medications such as lithium, a drug used to treat mental disorders, can contribute to hypothyroidism.
Congenital Disease -
Some babies are born without a thyroid gland or with a defective thyroid gland.
Pituitary Disorder -
The failure of the pituitary gland to produce enough thyroid-stimulating hormone (TSH) is usually caused by a benign tumor of the pituitary gland.
Pregnancy -
Some women develop hypothyroidism during or after pregnancy because they produce antibodies in their own thyroid gland. Hypothyroidism can increase the risk of miscarriage, premature labor and preeclampsia.
Deficiency of Iodine -
Too little iodine deficiency can cause hypothyroidism.
