Hypovitaminosis refers to a deficiency of vitamins in the body, which can lead to various health issues. This condition occurs when an individual does not consume enough vitamins through their diet or has difficulty absorbing them. Common vitamins involved include Vitamin D, Vitamin C, and Vitamin B12, each playing crucial roles in bodily functions. Symptoms of hypovitaminosis vary depending on the specific vitamin lacking. For instance, a deficiency in Vitamin C can lead to scurvy, characterized by fatigue and gum disease, while a lack of Vitamin D may result in weakened bones. Addressing hypovitaminosis typically involves dietary changes or supplementation.
