Can rickets be cured? Rickets is a type of nutritional disease caused by a deficiency of vitamin D, which disrupts the body's calcium and phosphorus metabolism and leads to abnormal bone development. The common form is nutritional vitamin D deficiency rickets. This type of disease is self-limiting and can be cured. Once children engage in sufficient outdoor activities and supplement their vitamin D levels, they can be completely cured. There are also some special cases, such as severe liver and kidney diseases caused by vitamin D deficiency, and some genetic diseases. These diseases require treatment to promote the absorption of vitamin D. However, for genetic diseases, treating rickets with vitamin D is ineffective, and these cases are more difficult to treat. For liver and kidney diseases, if the condition can be effectively controlled, they can also be cured.
