Deficiencies
Certain metabolic disorders, which include coenzyme Q10 deficiency [2] and Menkes disease [3], can result in low body temperature in infants. These conditions are quite rare and can result in feeding difficulties, lethargy, weak muscle tone, and seizures. Other factors include low oxygen levels and a large head-to-body proportion, as they lose 75 percent of their body heat via their head.
Hypoglycemia
Hypoglycemia [4] refers to a condition whereby the body has a small amount of blood sugar or glucose circulation. The main purpose of glucose in the body is for energy. Some of the major causes of hypoglycemia in babies include birth abnormalities, infection, and the health condition of the birthing parent during the pregnancy period.
