What is the Casimir Effect? The Casimir effect is a small attractive force that acts between two close parallel uncharged conducting plates. It is due to quantum vacuum fluctuations of the electromagnetic field. The effect was predicted by the Dutch physicist Hendrick Casimir in 1948. According to the quantum theory, the vacuum contains virtual particles which are in a continuous state of fluctuation (see physics FAQ article on virtual particles).
1 Mild high blood pressure. 2  Hypothyroidism may slow the heart rate to less than 60 beats per minute, reduce the heart's pumping capacity, and increase the stiffness of blood vessel walls. 3  All of these effects may lead to high blood pressure.
Severe hypothyroidism. When TSH is higher than 30 mlU/L and free T4 and T3 are low hypothyroidism is considered to be severe. Some common symptoms are fatigue, brain fog, feeling cold, hair and skin changes, puffiness of the face, muscle and joint aches and pains, low sex drive and depression.SH raises in proportion to degree of hypothyroidism. Increased TSH is earliest evidence of hypothyroidism and normally is sufficient to make the diagnosis. However, the measurement of free form of T4 and T3 thyroid hormones and thyroid antibodies are helpful to establish the cause of hypothyroidism.
