Survival Of The Sickest Summary

After watching the documentary Sick Around America, I have to say that it depressed me. I do not believe that everyone has equal access to healthcare in the United States. I believe with the Healthcare Reform things have improved slightly allowing more Americans to have the opportunity to have healthcare; however, there are those families who make slightly more than the cutoff bracket to receive the cheapest premiums through the government and then are forced to buy healthcare that is still too expensive, and if they do not have healthcare they will receive a large penalty. I believe a lot of families in the working and middle class populations will still have difficulty affording healthcare premiums. Also, just because families can pay the

In chapter one it talks about how hemachromatosis is a hereditary disease and it’s the most common genetic disease for people of European descent, in which the body can't register that it has enough iron. So it keeps absorbing as much of it as possible, and this can have very, serious side effects (including death). Iron is very important for bacteria, cancer, and other things to grow. The way this disease is most easily treated is blood letting. Looks like all those crazy blood-letting, leech-sticking doctors weren't mistreating everyone. What is the author's argument for why this disease stuck around? To really simplify things: during the black plague in Europe, people with more iron in their system were more likely

People of the Old World had domesticated pigs, horses, sheep, and cattle(1), which had acted as pathogens to infect the Europeans with diseases. In addition, diseases were constantly circulated with centuries of war, exploration, and city building. During the process of natural selection, disease-intolerant

Iron Deficiency Anemia affects millions of individuals across the world. This disease strikes many more women than men and has harmful effects on all who suffer from this deficiency that causes oxygen-carrying capacity to decrease. The causes can vary amongst different groups, but the aggravating symptoms remain constant. Much of the research on Iron Deficiency Anemia concentrates on not only the treatment of this disease, but also the prevention of it. To attain a better understanding of how to treat this problem, one must clearly know what Iron Deficiency Anemia means, what causes this disease, the effects of it, and finally how to cure it.

Hemochromatosis is a genetic disease in which there is too much iron that builds up in your body, this is referred to as an iron overload. Iron is an essential nutrient found in many foods but can be toxic to our bodies if we have to much. “Normally, humans absorb about 8-10% of the iron found in foods that they eat.” People with Hemochromatosis can absorb up to four times more iron than a normal human being. Since our bodies have no natural way to get rid of the extra iron, it gets stored in your body tissue including the liver, heart, pancreas and many other areas of our body can also be infected by this iron overload.

“What doesn’t kill us, makes us stronger” (p. 28). In the scientific novel Survival of the Sickest by Sharon Moalem with Jonathan Prince, self-acclaimed “Medical Maverick” Dr. Moalem makes in-depth analyses of current human diseases that, ironically, may have led to the survival of mankind in the past. He presents a novel concept that greatly contradicts what have been universally accepted beliefs surrounding biology and the process of human evolution for a long time. With the use of myriad scientific studies and research, he formulates surprising theories about a positive correlation between disease and humanity. Moalem narrates the scientific world’s findings that strongly exemplify his assertions, however arbitrary they may seem at first. Three of the diseases that he examines, hemochromatosis, Type 1 diabetes, and favism, could have been particularly useful for resistance against other illnesses and survival in a historically harsh environment.

Survival of the Sickest, written by author Dr. Sharon Moalem, is a book discussing why evolution has not allowed for the destruction of certain diseases. He states that these deadly diseases, such as Anemia, Hemochromatosis, and High Cholesterol, are in fact tools that evolution used to help the human race survive. He explains how these diseases helped fight against more dangerous and life threatening sicknesses such as, Malaria, the Bubonic Plague, and Vitamin D deficiency related illnesses. The main idea of this book is a simple one. Evolution did not necessarily favor adaptations that made us better. Instead, it favored adaptations that helped us survive. Even if these adaptations would end up killing us in the long run.

Hemochromatosis, also called iron overload, is a disease when the body absorbs too much iron from the food we eat and most often affects the liver, heart, pancreas, and skin. It is usually caused by genes in the body that mutate keeping them from working. Some signs and symptoms of this disease are weakness, joint pain, low libido, and/or if the disease has progressed to far diabetes or heart failure. Hemochromatosis is one of the more difficult diseases to diagnose because many symptoms are nonspecific and usually many people don’t show as many symptoms except elevated iron levels in their blood. Most will be treated with blood transfusions until the normal level of iron is reached. If diagnosed early the prognosis is excellent with possible checkups or phlebotomies.

Take hemochromatosis, a hereditary condition that causes iron to accumulate in a person's body. A person having hemochromatosis

Hemochromatosis is a deadly disease in which the body believes that it never has enough iron. The body, as a result is that iron is not filtered out through the intestines, it is always entering the body. This iron runs out of places to be stored, and is spread throughout the body. These iron stores eventually end up changing the body and causing damage to major organs and joints. Hemochromatosis can lead to cancer, heart failure, and a plethora of other problems.

While watching the film “Sick around the World,” I learned that one of the first statements made on the video was extremely true. The statement made was, “other countries do much better than the U.S but spend a lot less money.” There were numerous innovations that impressed me from several different countries. The countries with innovations that stuck out the most were Germany, Japan, and Taiwan.

Like the world around us the medical field is always changing. It is always pushing forward, trying to understand mysteries of the human body that have boggled researchers for decades. What confuses scientists more, are the organisms or conditions that create these abnormalities that can send the human body into a downward spiral. Disease is something that has affected human civilization since the dawn of time. It can either be chronic or acute, but in either case it has the potential to bring havoc to the human body systems that can lead to devastating consequences. Generally there are two main types of diseases, ones caused by invading pathogens and those which are hereditary. One hereditary disease that can be particularly tragic is

Hippocrates of Cos, a physician in ancient Greece, is considered to be the father of medicine due to his many contributions to the field in his life. Through research and different experiments he was able to conclude many different principles, including on of the most important: the four humors. By observing reactions to different illnesses, sometimes leading the patient to die, he was able to develop the theory. His theory of the four humors was that the human body was filled with four basic substances, or humors, that when in balance indicate the person is healthy. If there was too little or too much of one of the four, a disease or disability would result. The four humors of Hippocratic medicine are black bile, yellow bile, blood, and phlegm. Before the humors were introduced, many people believed that the source of illness was punishment from the Gods. It wasn’t until after Hippocrates’ introduction to medicine that the field stepped away from religion and into science.

Interestingly, the adaptation of humans to disease may date all the way back to the bottleneck that would eventually change our ancestors into behaviorally modern humans. A theory has been proposed that the activation of two genes that affect the human immune system created the modern human around 100,000 years ago. According to the study’s theory, humans have been adapting to disease for thousands of years. Clearly, disease and the adaptations of humans are correlated to their environment (LaFee, S., 2012).

The impact of medical advancement on human evolution is obvious. Earlier in time, some of our ancestors who managed to adapt to the new habitat continued their DNA’s spread to the future generations. But nowadays, medicinal advancement allowed the group of people who wouldn’t have been able to continue their lives to devote to the future human gene base, creating a greater variation in human genes and the evolution of the species. However, the major repercussion of this medical advancement has been the growth of the genes that have weak defiance against the diseases. It almost seems like there will be a greater reliance on medicine for the survival of humans.
