Explain the nature of two named physiological disorders
Explain the signs and symptoms
Describe the investigations that are carried out to enable the diagnosis.
The two physiological disorders I will be talking about in this assignment is hypertension and Diabetes.
Pulmonary hypertension
Pulmonary hypertension is a lung disorder. The arteries that carry blood from the heart to the lungs become narrowed, making it very hard for the blood to get through the vessels, this then causes the pressure in the arteries to increase more than usual (high blood pressure). Scientists think that the procedure starts with injury to the layer of cells that line the small blood vessels of the lungs. This injury, which occurs for unknown reasons, may cause changes in the way these cells interact with the smooth muscle cells in the vessel wall. As a result, the smooth muscle contracts more than normal and narrows the vessel.
The high pressure then puts more pressure on the right ventricle of the heart, causing it to get bigger. This then causes the right ventricle gradually becomes weaker and loses its ability to pump enough blood to the lungs stronger than usual.
Pulmonary hypertension comes in people of all ages, races, and ethnic backgrounds although it is much more common in young adults and is twice as common in women as in men. It is known to be inherited in a small number of people. Usually if members of a family suffer from it, it can be carried down in generations and could prevent long-term damage from happening.
Signs and Symptoms
Symptoms of pulmonary hypertension do not usually happen until the condition has been going on for a long time. The first symptom of hypertension is usually shortness of breath within doing simple activities such as climbing the stairs. Feeling exhausted, dizzy, and faint can also be some of the symptoms. Some signs can be swelling in the ankles, abdomen and legs; bluish lips
