Symptoms of Type 2 diabetes
Type 2 diabetes often develops slowly from a condition called prediabetes, and symptoms may not be apparent for years. Symptoms can include excessive thirst, which develops because hyperglycemia, or high levels of glucose in the blood, acts as a sponge to pull fluid out of the body’s tissues. This leads to dehydration and extreme thirst as well as frequent urination. This also pulls fluid away from the eyes, resulting in blurred vision.
