What are signs of compromised immunity?

The body gives unmistakable signs when immune function becomes weakened, indicating the need for attention. Frequent colds that last longer than usual indicate a poor defence against pathogens. Slow-healing wounds indicate an inadequate response by white blood cells. A feeling of persistent fatigue, even when resting enough, suggests a state of chronic inflammation. Digestive disorders often indicate a disturbance in the gut and the immune system, requiring treatment.

Infection Frequency

  • More than 4 colds annually indicates impairment
  • Reflects poor natural killer cell activity
  • Suggests vitamin D or zinc deficiency

Healing Delays

  • Cuts taking over 2 weeks to heal
  • Indicates poor neutrophil migration
  • Linked to protein or vitamin C deficiency

Based on clinical immunology markers

Ongoing digestive distress adds to the diagnosis of immune compromise. Bloating, gas, or irregularity of bowel movements indicate a failure of the gut barrier, which permits undigested particles to enter the bloodstream, evoking inflammation. Food sensitivities occur from hyper-reactive immune cells. General healing of the gut lining resolves many systemic problems.

Immunosuppression is shown with recovery failures associated with stress. If small illnesses persist for weeks, corticosteroids may likely impair the actions of lymphocytes. An alteration in hormone levels affects the functions of interleukin-2, which is essential for the coordinating properties of the defense system. Moreover, in the stress management plan, recommended daily routines, such as breathwork or time in nature, are beneficial.

A professional evaluation is indicated in the presence of many symptoms that have persisted. Blood testing will evaluate immunoglobulin levels and the number of white blood cells. A stool test will find variations in the gut microbiome. Deficiencies can be addressed through a balanced diet of whole foods. If this is inadequate, targeted supplementation can be provided upon agreement with the practitioner to restore optimal levels.
