Obesity or diabetes can develop in adulthood. In addition, problems with the digestive tract and the urinary system are also possible. Medical problems involving vision or hearing, including sensitivity to sound (hyperacusis), are frequently associated with Williams syndrome. Affected people may also have increased calcium levels in the blood (hypercalcemia) in infancy, developmental delays, problems with coordination, and short stature. Individuals with Williams syndrome have an increased risk of complications with the use of anesthesia.Īdditional signs and symptoms of Williams syndrome include abnormalities of connective tissue (tissue that supports the body's joints and organs) such as joint problems and soft, loose skin. Other problems with the heart and blood vessels, including high blood pressure ( hypertension) and stiff blood vessels, have also been reported in people with Williams syndrome. Narrowing of other vessels, including the artery from the heart to the lungs (pulmonary stenosis) and the arteries that supply blood to the heart (coronary artery stenosis) can also occur. If this condition is not treated, the aortic narrowing can lead to shortness of breath, chest pain, and heart failure. Supravalvular aortic stenosis is a narrowing of the large blood vessel that carries blood from the heart to the rest of the body ( the aorta ).

Older children and adults typically have a longer face with a wide mouth and full lips.Ī form of cardiovascular disease called supravalvular aortic stenosis (SVAS) occurs frequently in people with Williams syndrome. Many affected people have dental problems such as teeth that are small, widely spaced, crooked, or missing. Young children with Williams syndrome have distinctive facial features including a broad forehead, puffiness around the eyes, a flat bridge of the nose, full cheeks, and a small chin. Attention deficit disorder (ADD), problems with anxiety, and phobias are common among people with this disorder. Affected individuals have outgoing, engaging personalities and tend to take an extreme interest in other people. People with Williams syndrome typically have difficulty with visual-spatial tasks such as drawing and assembling puzzles, but they tend to do well on tasks that involve spoken language, music, and learning by repetition (rote memorization). This condition is characterized by mild to moderate intellectual disability or learning problems, unique personality characteristics, distinctive facial features, and heart and blood vessel (cardiovascular) problems. Type O positive blood is one of the first to run out during a shortage due to its high demand.Williams syndrome is a developmental disorder that affects many parts of the body.Those with O positive blood can only receive transfusions from O positive or O negative blood types.Type O positive blood is critical in trauma care. The risk of reaction is much lower in ongoing blood loss situations and O positive is more available than O negative. In major traumas with massive blood loss, many hospitals transfuse O positive blood, even when the patient’s blood type is unknown.Learn more about how you can be a Hero for a Baby. O positive donors who are CMV negative are known as Heroes for Babies at the Red Cross because it is the safest blood for transfusions for immune deficient newborns.That’s another reason it’s in such high demand. Over 80% of the population has a positive blood type and can receive O positive blood.O positive red blood cells are not universally compatible to all types, but they are compatible to any red blood cells that are positive (A+, B+, O+, AB+).38% of the population has O positive blood, making it the most common blood type.Type O positive blood is given to patients more than any other blood type, which is why it’s considered the most needed blood type.
