Primary Immunodeficiencies

Primary immunodeficiencies are a group of disorders that affect the immune system, making it difficult for the body to fight off infections. These disorders can be inherited or acquired, and they can range in severity from mild to life-threatening.

Types of Primary Immunodeficiencies

There are many different types of primary immunodeficiencies, each with its own unique set of symptoms and causes. Some of the most common types include:

• B cell deficiencies affect the production of B cells, which are white blood cells that produce antibodies. Antibodies are proteins that help the body fight off infections.
• T cell deficiencies affect the production of T cells, which are white blood cells that help the body fight off infections.

Malnutrition

Malnutrition: results from a poor diet or a lack of food. It happens when the intake of nutrients or energy is too high, too low, or poorly balanced. Malnutrition involves a dietary deficiency. People may eat too much of the wrong type of food and have malnutrition. Undernutrition can lead to delayed growth or wasting, while a diet that provides too much food, but not necessarily balanced, leads to obesity. In many parts of the world, undernutrition results from a lack of food. In some cases, however, undernourishment may stem from a health condition, such as an eating disorder or a chronic illness that prevents the person from absorbing nutrients.
