Correct Answer Is Option = Diabetes
Notes / Explanation
The deficiency of insulin, or the failure of the body to use insulin properly, causes the disease known as diabetes, which is one of the most common and important health conditions in the world today. Insulin is a hormone produced by the pancreas, and its function is to control the level of sugar in the blood by helping the cells of the body to take in and make use of the sugar that comes from food. When the body does not produce enough insulin, or when the insulin that is produced is unable to act effectively, the sugar that should be taken up by the cells instead remains in the blood and builds up to abnormally high levels, and this condition of persistently high blood sugar is what is known as diabetes. There are different forms of the disease. In one form, the body is unable to produce insulin at all or produces very little, often because the cells that make insulin have been damaged, and people with this form need to receive insulin from outside the body in order to survive and manage their condition. In another and more common form, the body still produces insulin but is unable to use it effectively, a situation that is often associated with factors such as being overweight, lack of physical activity and unhealthy diet, and this form can often be managed through changes in lifestyle along with medication. If diabetes is not properly controlled, the high levels of sugar in the blood over a long period can cause serious damage to various parts of the body, including the heart, the blood vessels, the eyes, the kidneys and the nerves, leading to a range of complications. For this reason, the management of the condition through proper diet, physical activity, monitoring of blood sugar and appropriate treatment is very important. The disease has become increasingly common in many parts of the world, which is linked to changes in lifestyle and diet, making awareness and prevention important matters of public health. For PPSC and other competitive examinations, the key points to remember are that the deficiency of insulin, or the body's inability to use it properly, causes the disease known as diabetes, that diabetes is marked by high levels of sugar in the blood, that there are different forms of the disease, and that if it is not controlled it can damage many parts of the body over time.
