Excessive Thirst and Urination
A person with either type 1 or type 2 diabetes may suffer from constant thirst and frequent urination because extra sugar has built up in their blood system. The kidneys work overtime to correct the situation, which means that excess sugar is moved to the urine. Accordingly, urination must become more frequent, which can cause dehydration and thirst.
This is most often seen with type 1 diabetes, though it may manifest in people with type 2. Weight loss happens because increased urination drains calories from the body. The disease also keeps cells from receiving the nutrients they need, which leads to increased hunger.
Fatigue is among the most common symptoms for people with type 1 and type 2 diabetes. Dehydration and decreased conversion of sugar into useable energy mainly account for feeling constantly tired. This is also one of the most frequently misdiagnosed of diabetes symptoms.
Overall dehydration pulls essential fluids from the eyes. This may cause vision to blur. Serious complications can arise when this condition is not treated.
