الدكتور الفايد | D | لماذا نقص الفيتامين " د " في الجسم؟

Vitamin D is not actually a vitamin, but a hormone produced in the body as a result of sun exposure. It can also be obtained from certain foods. The Importance of Vitamin D: This hormone facilitates the absorption of calcium from food in the digestive system. Therefore, a deficiency can lead to decreased calcium absorption from food. As a result, calcium is released from the bones to maintain a stable blood calcium level. This can lead to bone problems (rickets in children or osteoporosis in adults), muscle damage, and high blood pressure. Research also suggests a link between low vitamin D levels and diabetes, autoimmune diseases (where the immune system attacks the body, such as lupus - SLE), and certain types of cancer. Vitamin D deficiency is very common among both adults and children. This seems to stem from a lack of sun exposure and the widespread use of sunscreen in recent years, following increased awareness of the health risks associated with excessive sun exposure, such as a higher risk of skin cancer. Vitamin D excess is a very rare condition requiring the consumption of large amounts. In extreme cases, this excess can cause high blood pressure, weakness, high blood calcium levels, kidney stones, and decreased concentration. A vitamin D test actually measures the level of one of its metabolites, 25-hydroxyvitamin D (25-OH-Vitamin D). The channel was created on November 13, 2018, by a Moroccan production company before being sold in mid-2020, along with all its recordings and trademark. The network operates with a library of over 600 videos recorded with the same production company under a contract between the program host and the producer, a copy of which we retain for legal purposes. In this context, we would like to inform our Arab viewers, and especially those in the Maghreb, that the doctor is no longer active on this channel. We also wish to inform you that the purpose of continuing this channel is to compile all the recorded lessons available under legal contracts.
