Chronic stress – when the nervous system controls health<\/h1>\n


\n<\/p>\n

\n
\"\"<\/div>\n<\/figure>\n

Many patients suffer from exhaustion, sleep disorders, digestive problems or hormonal complaints without a clear cause being found in conventional diagnostics.<\/strong> The common denominator is often a permanent malfunction of the nervous system.<\/p>\n

Chronic stress not only has a psychological effect, but also alters fundamental biological regulatory processes in the body.<\/p>\n

\n

What is medically understood by chronic stress<\/h2>\n

Stress is initially a sensible adaptation reaction of the body. It enables performance and survival in the short term. Stress becomes problematic when the activation remains permanent and there is no longer a sufficient recovery phase. <\/p>\n

The body then remains predominantly in the so-called:<\/p>\n

    \n
  • Alarm and power mode<\/li>\n
  • increased stress hormone levels<\/li>\n
  • Reduced regeneration<\/li>\n<\/ul>\n

    This permanent activation is controlled by the nervous system – usually unconsciously.<\/p>\n

    \n

    The autonomic nervous system as a central control center<\/h2>\n

    The autonomic nervous system regulates almost all involuntary bodily functions. It consists of two main parts: <\/p>\n

      \n
    • Sympathetic nervous system:<\/strong> activation, performance, stress response<\/li>\n
    • Parasympathetic nervous system:<\/strong> regeneration, digestion, healing<\/li>\n<\/ul>\n

      In the case of chronic stress, this balance shifts in favor of permanent activation.<\/p>\n

      How chronic stress affects the body systemically<\/h2>\n

      Persistent stress does not have an isolated effect, but influences several body systems simultaneously.<\/p>\n\n\n\n\n\n\n\n\n

      Why stress is often underestimated<\/h2>\n

      Many sufferers do not perceive their condition as exceptionally stressful. The nervous system can adapt to constant stress so that the condition is subjectively perceived as “normal”. <\/p>\n

      However, the body itself does not differentiate between occupational, emotional or internal stress – it reacts to the duration of the stress.<\/p>\n

      \n

      Interim conclusion<\/h2>\n

      Chronic stress is not a lifestyle problem, but a key medical factor.<\/strong> If the nervous system is not included in the diagnosis and therapy, many complaints persist despite treatment.<\/p>\n

      \n

      Frequently asked questions from practice<\/h2>\n

      Can stress actually cause physical illness?<\/h3>\n

      Yes, chronic stress affects the autonomic nervous system, hormonal control circuits, the immune system and the metabolism and can therefore trigger or intensify physical complaints. <\/p>\n

      Why do I often not consciously feel stress?<\/h3>\n

      The nervous system can adapt to constant stress. The condition is then subjectively perceived as normal, although the body remains permanently in activation mode. <\/p>\n

      How can stress dysregulation be medically diagnosed?<\/h3>\n

      In addition to a detailed medical history, functional diagnostics can provide indications of dysregulation of the autonomic nervous system and the stress axes. In my practice, I offer the VNS analysis<\/a>, which can objectify stress very well. <\/p>\n
