Early Symptoms of Diabetes

Spotting diabetes when it is still at an early stage can help you treat it easier. However, early diagnosis of the disease is not a common thing, because few people recognize symptoms of it shortly after its onset. Here are the telltale signs that can help you realize you might benefit from a visit to endocrinologist.

Many people do not know they have the disease until the symptoms characteristic of later stages develop. It is especially true of type 2 diabetes. However, there are certain symptoms which can give you a hint about what is going on in your body.

Symptoms that should not be overlooked

Unlike type 2 diabetes, the symptoms of which may take quite a long time to appear, type 1 diabetes manifests itself in symptoms that occur in a couple of days or weeks. The symptoms are mostly the same regardless of disease type.


Since diabetes implies increased levels of glucose, those suffering from it are likely to want to eat more often. The mechanism behind it is the following: a human body needs energy to maintain its functions, and in order to get it, it delivers glucose into cells to produce energy. Insulin is used by the body to bring the glucose into cells, and if there is not enough insulin or it cannot be used properly, the body starts lacking energy. It is because of this lack of energy that those with diabetes are often hungry.


This symptom is closely related to the previous one: due to the lack of energy resulting from the inability of cells to produce it, you always feel tired. Even after you have eaten, you do not feel full, because you hardly get any energy from the nutrients you have consumed. Actually, eating a lot makes matters worse, as eating results in higher blood sugar.

Thirst and polyuria

Excessive thirst is a major sign of diabetes, and frequent urination is its natural consequence. If you are healthy, kidneys are supposed to reabsorb the glucose that gets into them. In case of diabetes, they cannot absorb all the sugar from the bloodstream, and so they produce more urine using the liquids they take from your tissues. As there is less liquid in your tissues than there should be, you feel dehydrated and start drinking and consequently urinating more often. While a healthy person urinates four to eight times in 24 hours, those with diabetes have to go to the toilet more often.

Itchy skin

The fluid supply available in your body is limited, and when kidneys start requesting more, other organs are affected. The skin is no exception: when it does not have enough fluid, it becomes itchy. Another symptom related to insufficient water supply in tissues is dry mouth.

Blurred vision

Although blurred vision does not necessarily mean you have diabetes, as there are many eye problems associated with it, it can result from the disease in question. Such a patient’s vision becomes blurred because the lenses in the eye change their shape, they swell up, and it affects vision.

Weight loss

In some people, diabetes can manifest itself in unexpected weight loss. The inability to get enough energy using the nutrients you consume forces cells to burn muscles and fat. Besides, frequent urination leads to dehydration, which contributes to weight loss.

There are also other symptoms, which are characteristic of a certain type of the disease, though they can appear regardless of type – it’s just that they are more likely to develop in those suffering from a particular type of diabetes.

For example, weight loss affects patients with type 1 diabetes more often. Among other type 1 diabetes common symptoms are nausea and vomiting. As far as type 2 diabetes is concerned, there can be yeast infections and slow-healing cuts or sores.

If you feel you have some of the symptoms mentioned above, do not hesitate to consult your GP!
