P1- Explain the nature of TWO named physiological disorders. In this assignment I will be looking at the nature of two named physiological disorders. I will explain its sign and symptoms and access possible difficulties involved in the diagnosis of the disorders from their signs and symptoms. The two physiological disorders are coronary heart disease and breast cancer. Coronary heart disease: Coronary heart disease is the build-up of plaque such as cholesterol and other fatty substances within the coronary arteries causing a reduced or no supply of oxygen to the heart. The process of plaque lining the coronary arteries is called arteriosclerosis. Coronary heart disease can be caused and triggered by many different factors. These include: Smoking; lifetime smoking roughly doubles your risk of developing heart disease because the chemicals in tobacco get into the bloodstream from the lungs and they damage the blood vessels and other parts of the body. It is one of the leading causes of cardiovascular disease; High blood pressure; the blood pressure can become dangerous the higher it gets. An increased of blood pressure is an increase of the force of blood against the walls of the arteries and the higher the blood pressure the higher the likelihood the walls of the arteries can become damaged. This can lead to stiffness of the arteries making them less flexible which can lead to the build-up of cholesterol, even after being used on cells the extra gets deposited inside the artery wall lining which can lead to atherosclerosis and this can occur from unhealthy diet intake. Your blood pressure and cholesterol level are also important. All people aged over 40 should have a cardiovascular health risk assessment’ usually available at your GP surgery. If you have a high risk of developing cardiovascular disease, treatment to reduce high blood pressure (hypertension) and/or cholesterol may be advised. Physical activity like exercising helps reduce blood pressure and the likelihood of obesity; Diabetes, people with diabetes have the same risk of developing heart disease as a person who has had a heart attack but who doesn’t have diabetes; obesity, obese individuals are more likely to have high blood pressure, diabetes and high blood fats. If your blood vessel are narrow due to a build-up of atheroma or if the symptoms of coronary heart disease cannot be controlled using medication, surgery may be needed to open up or replace the blocked arteries in severe cases heart transplants may even be needed if the heart is too damaged to function after a serious build-up of plaque or after a heart attack. Breast cancer: Breast cancer is the serious disorder that is very common amongst both men and women in today’s day and age. In the UK about 1 in 8 women develop breast cancer at some stage of their life and also it is the most common frequently investigated cancer in quality of life studies. The breasts and every other part of our body is made up of millions of individual cells normally they would function to multiply and grow in an orderly way the body has implicated, however in cancer this process goes wrong and dysfunctional cells begin to multiply rapidly and uncontrollably. It has not been proven why exactly the breast cancer is caused however there are many risk factors that are associated with breast cancer which if taken into consideration can help reduce the risk of the likelihood of getting breast cancer. Some of the risk factors: obesity and alcohol abuse; if a woman loses weight and limits alcohol intake, her risk of developing breast cancer may diminish; age, it is most common for women to develop breast cancer at an older age particularly women who have been through menopause and are over the age of 50; and some studies also have shown that diet and vitamins play a role in breast cancer risk the use of antiperspirants containing specific chemicals and environmental chemical use are also uncertain risk factors; previous breast...
