Diabetes (type 2), in simple terms, is when the insulin produced in the body fails to make proper use of it due to which the level of glucose in the blood increases. At this time, the body is said to be resistant to insulin. The other situation for diabetes is insufficient production of insulin in the body. This results in the deposition of sugar in the blood because glucose is not converted into energy which acts as the fuel for the body (type 1).
It has been very difficult to find the exact causes of diabetes, even though many research projects have been done. Some factors have been found which can cause diabetes. These factors when detected should be immediately treated properly.
One of the basic causes of diabetes is poor or improper diet. The diet containing high amount of fats and carbohydrates is not harmful to the body but it hinders the functioning of the pancreas. Due to this, the generation of insulin in the pancreas reduces which in turn increases the level of blood sugar thereby becoming the victim of diabetes.
Obesity is also considered to be one of the major causes of diabetes. There is a dysfunction of insulin in the person suffering from obesity because the tissue cells are resistant to insulin.
Diabetes can even be caused due to heavy stress or tensions. People suffer from different types of stress. Heavy work load and hectic schedules make the life of a person very busy and stressful. There can be emotional stress in the life of people. All these disturb the metabolism of the body. More worries and nervousness can also affect the blood sugar level which can cause diabetes. The rise in the blood pressure due to hypertension has proved to be directly affecting the diabetes.
Frequent smoking has worse effects on the body causing diabetes. Such smokers can also be affected by the diabetic retinopathy which is a disease affecting the eyes.
The person having inactive lifestyle has more chances of contracting with the diabetes. Such person should make a habit of doing the exercises for three or more times in a week in order to release from the contract of diabetes.
Age factor has been one of the causes of diabetes. Nowadays, diabetes is found in any age group of people but, mostly found in middle age and old age due to less practice of exercises.
From various research studies, diabetes has been found to be a hereditary disease. There are more chances of the child inheriting diabetes if both parents are diabetic.
There have been no answers for the question of why the pancreas sometimes stops secreting insulin in the body. But, one of the possible causes of diabetes is the infections in the pancreas which affects the production of insulin. It has been found that virus can attack the pancreas which affects the cells producing insulin. The stomach viruses as well as the bacteria are responsible for various kinds of damages which enable the ability to transmit proper signals to the liver. Such types of pathogens are usually found in the food products containing high amount of sugar. Glucose is also the best food for these micro-organisms.
