What is Prediabetes?

When your blood sugar levels are higher than usual, you have prediabetes. However, it’s not that high enough to be classified as type-2 diabetes. The blood sugar level ranges just below the cutoff for type-2 diabetes. Prediabetes serves as a warning indicator so that type 2 diabetes can be delayed or best averted. People with type-2 diabetes typically had prediabetes initially, but their disregard for their health caused it to progress to type-2 diabetes. Insulin resistance leads to prediabetes in a person. If your prediabetes HbA1c level, or the average blood sugar over the last two to three months, is between 5.7% and 6.4%, then you have prediabetes. HbA1c levels under 5.7% are considered normal, whereas levels over 6.4% signify type 2 diabetes. Prediabetes fasting glucose levels are another indicator of prediabetes. You may have prediabetes if your fasting prediabetes sugar level ranges between 100 mg/dL and 125 mg/dL. A diabetic has a fasting sugar of 126 mg/dL or above, while a normal person has one below 100 mg/dL. A glucose tolerance test (GTT) is a different method of determining prediabetes. A patient with prediabetes will have a GTT blood sugar ranging between 140 mg/dL and 199 mg/dL.

What Causes Prediabetes?

Prediabetes develops when insulin in your body does not work properly. Insulin primarily helps the blood cells to use glucose from your bloodstream. When your body is unable to use insulin effectively, then glucose levels in your blood rise. Higher levels of blood sugar than normal indicate prediabetes. Prediabetes sugar level is higher than normal levels but lesser than diabetes sugar levels. If you do not control prediabetes, it can develop into diabetes type-2. Such high glucose levels in your blood can damage your nerves and blood vessels as well.

Prediabetes Symptoms

Prediabetes Symptoms

Usually, prediabetes symptoms or signs of prediabetes are not generally detected. Mostly, people get prediabetes diagnosed by chance. This can happen during the medical screening or routine blood check. Therefore, it is important to keep checking your blood sugar if you fall in the category of people having a high-risk factor of being prediabetic. The warning signs of prediabetes may include:

Increased Hunger And Thirst

In symptoms of prediabetes increased thirst and hunger are top signs. Increasing blood sugar levels in your body are a result of a lack of insulin or insulin resistance. This means your body is not able to convert food into energy. Lack of energy, therefore, makes you feel more hungry and thirsty.

Unexpected Weight Loss

Lack of insulin or insulin resistance prevents your body from getting glucose from the bloodstream. It hence causes a lack of energy. Thereafter, your body starts burning fat and muscle to get energy. This causes overall body weight loss. This is another one of the top prediabetes symptoms.
