Stress Related Disorders
In a world where challenges are the order of the day, stress is bound to be present. Stress is an everyday fact of life. You can t avoid it, was written in 1982 by one of the many researchers on stress. Stress is a type of alarm reaction, which creates a heightened state of readiness both mentally and physically. It is a psychological as well as a physiological response to the environment.
The brain produces a stress reaction when you are in a situation that is physically or mentally demanding. Stress is normal. Some stress is good for you as it keeps you alert and protects you in times of danger or when you need to act or think quickly. For example, physical training to keep fit places stress on your body, but that stress has a beneficial effect provided you don’t overdo it. Feeling a bit stressed about impending examinations is normal. It usually helps to focus your energy into revising well.
Prolonged and unwanted stress, however, may lead to mental and physical ill-health. Stress cuts across class, age and gender. Its evolving complexity makes it a relevant subject to be addressed urgently today more than ever before. Current estimates show that about 80% of diseases treated in hospitals have a component of stress.
The first thing that happens when we are under stress is a part of our brain, the hypothalamic-pituitary-adrenal, HPA system is activated. This recognizes the stress as danger and pumps out neurotransmitters such as dopamine, norepinephrine, and epinephrine/adrenaline. These chemicals prepare the body to respond to the perceived danger. One of two things will happen. Either we tackle the source of the stress, usually a wild animal or an invading human, and fight it, or we run away. This is called the fight or flight syndrome. This syndrome is what is responsible for heroic and almost superhuman efforts in times of crisis, such as when someone lifts the front of an automobile off of an injured person after an accident. We can’t produce complex intellectual responses to stress; we just react. At that point in time, all non-essential body systems are shut down so that the body can react to the stress.
The chemicals released by the body prepare it for dealing with stressful events such as giving a speech, aiding an accident victim, or fighting or fleeing from attack. However, if the stress becomes chronic or out of proportion, this healthy response can become pathological. Some of us commonly live under a constant state of stress, continually triggering the stress response and depleting valuable reserves of energy and essential minerals and vitamins in the process. Those who surpass individual limits of stress suffer the consequences.
Having defined what stress is and the sort of response the body makes, we are going to use the rest of this article to focus on various types of stress-related disorders. Although stress can come from outside sources like a demanding boss or work schedule, a hurricane or heavy traffic, there are also internal sources of worry like perfectionism, disease, a difficult spouse, and/or spiraling debt which affects our bodies both physically and emotionally. When we experience stress, the body responds whether we want it to or not.
Various research studies acknowledge that stress is a major contributing factor to cardiovascular disorders like hypertension. The release of stress hormones like Cortisol increases blood pressure which in turn damages the wall of the blood vessels. These hormones may also cause faults in fatty acid metabolism which building up over time may cause narrowing of blood vessels. This makes it difficult for the heart to pump blood through them.
Other stress mediated cardiovascular events include palpitations and stroke. The activity of the adrenal glands is crucial to your mood, energy levels and ability to cope with stress. In extreme cases of stress your adrenal glands may become enlarged; the spleen and thymus glands may shrink and deep bleeding stomach ulcers may occur. Stress is also known for causing other gastrointestinal disorders like irritable bowel syndrome and also plays a role in causing some respiratory disorders. An example here is the feeling of suffocation by asthmatic patients when under stress. Stress is also alleged to be a factor in the development of cancer. In fact, recent research shows that there is a moderate correlation between exposure to life stressors and cancer; the more stressors, the higher the likelihood of cancer.
Some recent research suggests that stress smothers the activity of the immune system making one susceptible to infections. Students stressed by the death of a parent or a recent divorce have been found to have reduced immunity in comparison with their counterparts. Autoimmune disorders with stress factors include allergies and arthritis among others Stress has also been shown to influence mental health. Individuals harboring stress may be socially withdrawn, mentally unstable, have attention deficit, memory lapses, migraines and in extreme cases severe anxiety, depression, or other mental problems.
Another category of disorders caused by stress is the addictive disorder. This includes multiple substance abuse (alcohol, cigarettes and drug addiction), eating disorders or obesity.
It is important to have support systems that ensure that we do not fall prey to the ravages of stress. However, each person should also be vigilant to situations that may engender stress and try to avoid them. In the words of Johann Wolfgang von Goethe, Let everyone sweep in front of his own door and the whole world will be clean.
