Mottled skin in newborn babies
Some newborn babies have mottled skin. Usually, this benign condition goes away on its own. Exposure to cold temperatures frequently causes it. Treatment includes keeping the baby warm and avoiding the cold. There is usually no need to have additional medical treatment.
There is no one specific treatment for all mottled skin cases. Treatment depends on the cause of this condition and other symptoms that appear along with the skin mottling.
Shock requires immediate medical attention. Once the person is in the hospital or emergency room, they will likely receive oxygen and intravenous fluids and undergo tests so doctors can determine the underlying cause.
Vascular diseases are often treated with lifestyle changes and medications that lower blood pressure or cholesterol. You may also be given drugs that help prevent your arteries from narrowing.
