What Causes Poor Resistance?

When the body’s resistance is strong, harmful substances entering the body are promptly eliminated. Conversely, when resistance is weak, the body cannot effectively defend against viral or bacterial invasion. So, what causes poor resistance?

What Causes Poor Resistance?

Poor resistance results from damage to an individual’s immune system, a decline in immune factor levels, and impaired immune responses—failing to sustain normal immune function. When resistance is compromised—or when an individual suffers from an immune-related disorder—immune cells may mistakenly attack the body’s own tissues, further weakening resistance. Examples include systemic lupus erythematosus, leukemia, and rheumatoid arthritis. External environmental factors and certain foods may also trigger abnormal immune reactions. Additionally, weakness of the spleen-stomach system (in Traditional Chinese Medicine terms) or gastrointestinal disorders such as gastric ulcers or gastritis can impair nutrient absorption from food. This leads to reduced levels of essential nutrients—including amino acids and proteins—resulting in malnutrition, anemia, and diminished resistance.

Excessive physical fatigue and insufficient rest elevate autonomic nervous system stress, damaging both the endocrine and immune systems—and thereby reducing resistance. Similarly, irregular eating habits and consumption of unhealthy foods adversely affect overall health, naturally lowering resistance.

The body’s resistance plays a vital role—not only influencing daily well-being but also determining susceptibility to disease. We hope this explanation has been helpful. Wishing you a joyful life and optimal health!
