In this unit I will cover physiological disorders. Physiological disorders can be defined as a fault within the body as organs or systems causing illness, it is a physical disorder that prevents the body from functioning normally. The two different physiological disorders I will be talking about are Coronary Heart Disease (CHD) and Diabetes type 2.

Coronary heart disease (CHD):

Causes of CHD:
Coronary heart disease is usually caused by a build-up of fatty deposits on the walls of the arteries around the heart. The fatty deposit is called atheroma, which are made up of cholesterol and other waste substances. The build-up of atheroma on the walls of the coronary arteries makes the arteries narrower and limits the flow of blood to the heart. This …show more content…
The main symptoms of diabetes common to both types are feeling very thirsty, urinating frequently, particularly at night, feeling very tired, weight loss and loss of muscle bulk. Many people have type2 diabetes for years without realising because the early symptoms can be mild. Other symptoms of diabetes can include itchiness around the vagina or penis, blurred vision that is caused by the lens of your eye becoming very dry, cramps, and constipation and skin infections.

Hyperglycaemia (high blood glucose)

Type 2 diabetes develops when the pancreas which is a large gland behind your stomach is unable to produce enough insulin to control your blood glucose level, or when the body's cells don't respond properly to insulin that is produced.

Due to the lack of insulin or its inability to regulate blood glucose, your blood glucose levels may become very high. Hyperglycaemia can occur for several reasons, including eating too much, being unwell and not taking enough diabetes therapy. The main symptoms of diabetes are due to hyperglycaemia. They include extreme thirst, a dry mouth, blurred vision, drowsiness and a need to pass urine
