Rickets is a chronic nutritional disease primarily caused by a deficiency of Vitamin D, which leads to disturbances in calcium and phosphorus metabolism in the body, resulting in abnormal bone development. It is mostly seen in infants, especially common within the first six months, and particularly in babies younger than three months. Clinically, the symptoms are not very specific; the children may appear irritable and restless, they might cry suddenly, or become agitated and restless to the touch. Some children may exhibit excessive sweating, frequent head shaking, or even hair loss, leading to noticeable baldness at the back of the head. However, these symptoms are not very specific. Generally, blood biochemistry and Vitamin D levels need to be tested. Early X-ray findings of the bones can be normal.
