Pituitary dwarfism is caused by problems arising from the pituitary gland. The pituitary gland, also called the hypophysis, is a gland at the base of the brain that produces many different hormones. This gland is divided into the anterior (front) and posterior (back) halves. The anterior pituitary produces six hormones: growth hormone, adrenocorticotropin (corticotropin), thyroid stimulating hormone (thyrotropin), prolactin, follicle stimulating hormone, and lutenizing hormone. The posterior pituitary gland only produces two hormones: antidiuretic hormone (vasopressin) and oxytocin.
The growth process begins in the lower part of the forebrain in a small organ called the hypothalamus. The hypothalamus releases hormones that regulate the production of other hormones. When the hypothalamus releases growth hormone-releasing hormone (GHRH), the anterior pituitary is stimulated to release growth hormone (GH). Growth hormone then acts on the liver and other tissues and stimulates them to secrete insulin-like growth factor-1 (IGF-1). IGF-1 directly promotes the development of bone and muscle, causing bones to grow in length, and muscles to increase protein synthesis (make more protein).
Since growth is a complex phenomenon, it may be slowed down or stopped by abnormalities arising at any point in the process. Thus, dwarfism can result if there is a deficiency in any of these hormones, if there is a failure in the receptor cells receiving the hormonal stimuli, or if the target cells are unable to respond.
At its most basic, pituitary dwarfism results from decreased production of hormones by the anterior pituitary. When none of the hormones of the anterior pituitary are adequately produced, this is called panhypopituitarism. A common form of pituitary dwarfism is due to deficiencies in the production of growth hormone (GH). When less GH than normal is produced during childhood, an individual's arms, legs, and other structures continue to develop in normal proportions, but at a decreased rate.

I personally would say 15% due to the fact that most traffic accidents occur more further from home
Anemia is a condition where there is deficiency in healthy red blood cells or hemoglobin resulting in pallor or weakness. It results in low level of hemoglobin which is the protein that transports oxygen around the body. Lack of oxygen in the body will result to weakness, shortness of breath and dizziness. Nikoleta's symptoms of malaise, lethargy and being tired is usually caused by too much work of the heart. In anemic patient, the heart has to pump faster than normal because it has to supply red blood cells around the body. Since the heart is working double-time, it usually results to being tired, lethargic and malaise of the person with anemia. Nikoleta's pale skin is attributed also on the fact that she has low supply of red blood cells around the body. If Nikoleta is lethargic and always tired, little things may irritate her immediately, hence, her being cranky
Humans, when exhaling release carbon which helps them to make sugar, and as a biproduct plants release oxegen which humans inhale.
