In childhood, this condition is characterized by weak muscle tone (hypotonia), feeding difficulties, poor growth and developmental delay. From childhood, affected individuals develop an insatiable appetite, which leads to chronic overeating (hyperphagia) and obesity. Some people with Prader-Willi syndrome, particularly those with obesity, they also develop diabetes mellitus type 2 (the most common form of diabetes).
What are the signs, symptoms and characteristics of Prader-Willi syndrome? People with Prader-Willi syndrome often have mild to moderate intellectual and learning disabilities. Behavioral problems are common, such as tantrums, stubbornness and compulsive behavior. Many affected individuals also have sleep disorders.
Additional features of this condition include characteristic facial features, short stature, and small hands and feet. Some people with Prader-Willi syndrome have unusually white skin and hair color. The two affected males and affected females have underdeveloped genitals. Puberty is delayed or incomplete, and most of those affected are unable to have children (infertility).
