It can also be caused by diseases affecting the hypothalamus and pituitary gland. 34. Leptin is produced in the white adipose tissue and signals to the hypothalamus . 35. Normally the hypothalamus releases a hormone called gonadotropin releasing hormone ( GnRH ). 36. The GnRH is released by the hypothalamus by specialised nerve cells or neurones. 37. Rising levels of thyroid hormone feed back to inhibit the pituitary and hypothalamus . 38. It is expressed in particular in the lateral hypothalamus . 39. The lateral hypothalamus ( LH ) is involved in the initiation of eating. 40. Now we know some of the potential sites of the problem in the hypothalamus .
