Vitamin deficiencies occur when the body does not get enough essential vitamins, which are crucial for various bodily functions. These vitamins, such as Vitamin C, Vitamin D, and Vitamin B12, play important roles in maintaining health, supporting the immune system, and aiding in energy production. A lack of these nutrients can lead to various health issues, including fatigue, weakened immunity, and skin problems.
Common causes of vitamin deficiencies include poor diet, certain medical conditions, and lifestyle factors. For example, individuals who follow restrictive diets may not consume enough vitamins, while those with malabsorption disorders may struggle to absorb nutrients effectively. Addressing these deficiencies often involves dietary changes or supplementation to restore proper vitamin levels.
