Anxiety - Wide-Ranging Health Effects

Humans appear to be hard-wired for modest levels of anxiety as a fear-arousal warning mechanism. Anxiety may be characterized as uneasiness, fear, worry, and apprehension. Anxiety is a common psychological state in which the basic message is "get away from this situation". The state is usually accompanied by numerous physiologic components including surges of the hormone adrenaline, increased heart rate and elevated blood pressure, and increased blood flow to the major muscle groups as the body prepares for "fight or flight".

These are all normal responses to environmental threats. The overall process is orchestrated by the amygdala and hippocampus, two regions of the brain's limbic system which process memory, emotional response, and spatial navigation. But for many people, if anxiety states become frequent and prolonged by various developmental circumstances in childhood and their teenage years, they may begin to respond to perceived rather than real threats. The anxiety state may persist and even become the default condition for the individual.

Those with chronic anxiety may experience chronic back pain,1,2 chronic muscular tension, fibromyalgia,3 headaches, chest pain, shortness of breath, and heart palpitations. Chronic anxiety may cause a person to anticipate the worst, to have ongoing feelings of dread, to be constantly irritable and tense, and to experience panic attacks. Eventually the person may become worn out from the constant drain on their inner resources and a likely outcome is depression. The person simply cannot take any more stress.

Chronic anxiety has a specific impact on the musculoskeletal system. Persistently elevated levels of adrenaline create ongoing tension in the postural muscles of the lower back and the weight-bearing, antigravity gluteal muscles, pelvic musculature, and hamstrings. The long-term results may include chronic lower back pain, inflammation of the sciatic nerve, and lumbar disc disease. Of course, any of these health problems create more anxiety for the person, establishing a vicious circle of anxiety, pain, more anxiety, and more pain.

Solutions for chronic anxiety usually require multidisciplinary holsitic approaches. Nutrition, for example, is a key factor in restoring a person's homeostatic mechanisms. Significantly reducing one's intake of simple carbohydrates - soda, muffins, cookies, cake, fast food, and even juice - will often have a substantial impact. Making sure to have five servings of fresh fruits and vegetables every day will also provide great benefit. Healthy fatty acids are beneficial for brain function.

Chiropractic Neurology care can frequently provide considerable assistance to those with chronic anxiety. Dr. Jennings and Jennings Chiropractic Neurology Clinic has extensive training in the brain based approach to health, learning disabilities and emotional conditions. Frequently we find an "imbalance" of communication between different part of the brain. They can be considered timing delay or a decrease in sensory integration, not a chemical imbalance. By normalizing activity within the brain and nervous system and reducing muscular stress and tension, chiropractic care helps eliminate an unnecessary source of biochemical and physiologic stress.

Chiropractic care is about much more than bones, joints, muscles, ligaments, and tendons. The focus of Chiropractic Neurology is focused on the brain's control on the entire body including the musculoskeletal system, and yet the benefits of chiropractic care extend far beyond these connective tissue structures.

Chronic musculoskeletal tension results in numerous biochemical changes such as excessive and prolonged build-up of lactic acid, a metabolic end-product of muscular contraction. These metabolites, which are accumulating wastefully and unnecessarily, irritate local nerve endings. Nerve irritation leads to increases in local muscle tension, setting-up a vicious circle of muscle tension, nerve irritation, more muscle tension, and more nerve irritation. Importantly, the irritated nerves send signals to all the other parts of the body, causing increased levels of activity and unnecessary use of precious resources. In these circumstances, the person may become irritable, gets tired more easily, has sleep disturbances, and even may develop various diseases.

Chiropractic care is a powerful healing method that affects many body systems as a result of addressing stresses in the musculoskeletal system.
