Diabetes is a disease which prevents or severely hampers the breakdown of glucose. Diabetes comes in two forms, called type 1 and type diabetes. Type 1 is the rarest. Approximately only 5-10% of people with type 1 or type 2 diabetes have this. This condition results from the body's inability to produce insulin. Insulin is a hormone secreted by the pancreas that controls glucose levels in the blood. It helps glucose enter cells. Type 1 diabetes is usually diagnosed in children or young adults, usually under the age of 30. .
Symptoms include: frequent urination, excessive thirst, extreme hunger, unusual weight loss, increased fatigue, irritability, and blurry vision. There are many problems associated with diabetes type 1. An increased risk of heart attack and stroke are present due to less circulation. Diabetes can cause eye problems and may lead to blindness. People with diabetes do have a higher risk of blindness than people without diabetes. Early detection and treatment of eye problems can save your sight. However, most people who have diabetes have nothing more than minor eye disorders. .
Glaucoma is one problem diabetics get more often. It is 40% more likely in those with diabetes. Glaucoma occurs when pressure builds up in the eye because the aqueous humor drains slower than it should so pressure builds in the anterior chamber. People with diabetes are 60% more likely to get cataracts. People with diabetes also tend to get cataracts at a younger age and have them progress faster. With cataracts, the eye's clear lens clouds, blocking light. To help deal with mild cataracts, you may need to wear sunglasses more often and use glare-control lenses in your glasses. For cataracts that interfere greatly with vision, doctors usually remove the lens of the eye. Sometimes the patient gets a new transplanted lens. In people with diabetes, retinopathy can get worse after removal of the lens, and glaucoma may start to develop.
