Antibody Deficiency Syndromes (ADS) refers to a group of disorders that weaken the body's immune system, resulting in recurrent infections. The antonyms for ADS can be many, and they include a strong immune system, good health, robust immunity, healthy resistance, and adequate protection against disease-causing organisms. A healthy immune system is essential for fighting off infections and keeping the body free from disease. On the other hand, ADS can occur due to genetic defects, malnutrition, or other underlying health conditions that compromise the immune system function. It is important to maintain good health, which can be achieved through a balanced diet, exercise, and avoiding exposure to disease-causing agents.
