Symptoms of diabetes

Slightly elevated blood sugar does not necessarily cause clear symptoms. Significantly elevated blood sugar increases urination, thirst and leads to weight loss and tiredness.

When blood sugar rises, sugar enters the urine via the kidneys. Sugar-containing urea increases the amount of urine, causing increased thirst and the body to become dehydrated and lose energy. Losing sugar into urea leads to weightloss. Dehydration is often linked to anomalous blood salt levels, which may in part cause tiredness and cramping in muscles. High blood sugar may also change visual acuity, most often by reducing long sight.

Symptoms of type 1 diabetes

In type 1 diabetes, the symptoms of insulin deficiency and high blood sugar usually develop quickly and typically worsen over a few days or weeks. However, the actual disease process in the pancreatic cells may have been ongoing for weeks, months, or even years. As symptoms begin, it is important to seek treatment as soon as possible. A delayed diagnosis may lead to severe insulin deficiency and acute acidocis, i.e. ketoacidosis. Normal symptoms of ketoacidosis include nausea and stomach pain. In a more advanced state, it leads to a reduced level of consciousness.

Symptoms of type 2 diabetes

In type 2 diabetes, there are usually less symptoms and they take longer to develop. A vague feeling of tiredness, lack of energy and mood changes can easily be explained by other factors. Type 2 diabetes can also be incidentally revealed if your blood sugar is checked for screening purposes or in connection with another condition. If the blood sugar has been high for a longer period of time – and especially if person also has a high blood pressure and fat metabolism issues – type 2 diabetes may be revealed due to a related complication.
