He has a long-standing history of Crohn’s disease (an inflammatory condition of the bowel) and had already undergone surgery generic leflunomide 20 mg on line. When I inquired generic leflunomide 10mg on-line, he told me about having to care for his father who had recently died buy 20mg leflunomide with visa, and that he was laid off from a job that he had been working at for the last ten years safe 10mg leflunomide. His diarrhea and abdominal pain had become progressively worse and worse until he ended up with a bowel obstruction that could only be corrected by yet another surgery quality leflunomide 10 mg. He had ignored a growing problem for a long time 5 6 • Mindfulness Medication but his body hadn’t. I was frustrated that I could only try to fix the damage done after the fact, instead of helping Larry learn how to interfere with the progression of his disease while he still had a chance to avoid the knife. She had left her family back home and they were depending on her to send back money to support them. Clearly under tremendous pressure, she began to experience problems with abdominal pain and an irregular bowel pattern with alternating diarrhea and constipation, gas and bloating. She also began having difficulty sleeping and was experiencing headaches and fatigue, which are often some of the first symptoms of ongoing stress. All of her medical tests came back normal and I diagnosed her with Irritable Bowel Syndrome. Again, Mika’s body was reacting to the levels of stress in her life and I was forced to just help her treat her symptoms, knowing that until she lowered her stress levels, she was in for more suffering, pain and grief. What’s common to both of these patients and many others, is that their symptoms are really secondary to, or aggravated by, the stress in their lives. If they had been able to understand what their stress levels were doing to their bodies before it made them sick and if they also had some help to then reduce their stress, perhaps I may never have met them at all! Let’s start by taking a look at what both Eastern and Western philosophies have to say about how you create and deal with stress. Rather than seeing them as separate, I have tried to integrate the tools and concepts that I have found to be most useful, regardless of point of origin. This integrative approach merges the best of Eastern and Western philosophy, medicine, and psychology as a means to understand the mind, how each of us creates stress, and how you can best learn to manage and minimize it. What Your Body Has in Mind • 7 Autonomic Physical and Psychological Responses Have you ever had to consciously tell your heart to beat, or your lungs to breathe, in order to make sure that they were doing their jobs? Your heartbeat and breathing are both examples of what scientists call autonomic involuntary behaviours. That’s a fancy way of saying that these biological activities carry on independently, without you having to be actively aware of what’s going on. The same can be said for a lot of the mental activities that carry on in your life. As an example, see if any of the following scenarios are familiar to you: • Have you ever had an experience where you drove from one spot to another and have suddenly realized that you don’t recall driving the last few blocks, or even the whole trip sometimes? Your mind is constantly thinking, evaluating and judging, as well as going over what happened in the past and your plans for the future. It’s what it does naturally, but unlike the moment-to-moment activities of the heart, or the lungs, the automatic thoughts that go through your head are something that can be observed, examined, changed and released. Your thoughts are the product of your experiences, your history, your biology and most importantly, your habits. External events conspire with the internal workings of your mind to create stress. Because your mind has the ability to literally think about itself, you can often find ways in which your habitual patterns of thought are maintaining a stress response. The physical stress response that occurs when your mind perceives a threat is a powerful one. When Larry first lost his job, he thought constantly about how catastrophic this turn of events was. He felt that it was a threat to his financial and social status and potentially a threat to not only his own survival, but also the survival of his family. His body in turn helped him out by releasing adrenaline and cortisol, the body’s alarm bells, as well as other chemicals. These chemicals prepared him to fight or run, as if the origin of the threat were a predatory animal out for his blood. The pupils of his eyes grew bigger and his muscles received more blood in preparation for an immediate action like running or punching, but there was no one to run from and certainly no one to punch! As he continued worrying about his situation, his body could not sustain the initial stress response. His immune system also stopped working very well, so he got every cold and flu bug going around. He was tired all the time, because it’s hard work for the body to stay ready to fight, or run, around the clock. Needless to say, that even when Larry got a new job, he was still worried about making ends meet and his body continued to ‘help him’ by keeping up all the stress responses as best it could, until one by one, his body’s systems and processes began to break down.
