type 2 diabetes
When glucose builds up in the blood instead of going into cells, the cells are not able to function properly. Other problems associated with the build-up of glucose in the blood include:
- Dehydration. The build-up of sugar in the blood leads to excess glucose in the urine because the kidneys can’t deal with the high sugar levels. The sugar in the urine draws water with it, causing an increase in urination. When the kidneys lose the glucose through the urine, a large amount of water is also lost, causing dehydration.
- Diabetic coma (hyperosmolar hyperglycaemic non-ketotic syndrome). When a person with type 2 diabetes becomes severely dehydrated and is not able to drink enough fluids to make up for the fluid losses, they may develop this life-threatening complication.
- Damage to the body. Over time, the high glucose levels in the blood may damage the nerves and predispose a person to atherosclerosis (narrowing) of the arteries that can cause heart attack and stroke, and damage the eyes and kidneys.
Symptoms of type 2 diabetes
Type 2 diabetes can cause serious health complications. That’s why it is very important to know how to spot type 2 diabetes symptoms. Even pre-diabetes can increase the chance of heart disease just like type 1 or type 2 diabetes. Talk to your doctor about preventative measures you can take now to reduce the chance of type 2 diabetes and heart disease.
The symptoms of type 2 diabetes due to high blood sugar may include:
- Increased thirst
- Increased hunger (especially after eating)
- Dry mouth
- Frequent urination
- Unexplained weight loss (even though you are eating and feel hungry)
- Fatigue (weak, tired feeling)
- Blurred vision
- Loss of consciousness (rare)
- Recurrent infections, including thrush infections
Seek medical advice if you have any type 2 diabetes symptoms or if you have further questions about type 2 diabetes. It’s important to get diabetes testing and start a treatment plan early to prevent serious diabetes complications.
Type 2 diabetes may not be diagnosed until health complications have occurred. Most often, with type 2 diabetes there are no diabetes symptoms or a very gradual development of the above symptoms of type 2 diabetes. In fact, about 600,000 people in the UK have type 2 diabetes but don’t know they have it.
Other symptoms of type 2 diabetes may include:
