Symptoms of Type 1 diabetes in children include extreme hunger and thirst, fatigue, frequent urination, weight loss and blurred vision, explains Mayo Clinic. Symptoms of Type 2 diabetes are similar but also include itchy skin, slow healing of sores or cuts and numbness or tingling in the extremities, states WebMD.
The cause of Type 1 diabetes is not known, notes Mayo Clinic. However, in the majority of Type 1 diabetes, the body's immune system destroys islet cells. These cells are the insulin-producing cells found in a person's pancreas. When the islet cells are mistakenly destroyed, the person produces little or no insulin. Insulin is vital because it allows sugar to enter the cells in the body, providing energy to muscles and tissues. Some factors that may contribute to Type 2 diabetes are genetics and being exposed to certain viruses.
Some children are more likely to develop Type 2 diabetes, according to WebMD. This includes females and those with a family history of diabetes or insulin resistance. Children who are American Indian, African-American, Asian, or Hispanic/Latino are also more likely to develop Type 2 diabetes. However, obesity is the cause of the majority of childhood Type 2 diabetes. Rarely, a hormone problem or other medical condition is the cause of obesity. More commonly, unhealthy eating, inactivity or having family members who are overweight contribute to obesity.
