Signs And Symptoms Of A Diabetic Reaction

Diabetes is a metabolic disorder in which the pancreas do not produce enough insulin or the cells do not respond to the insulin, thereby producing high blood sugar. There are two types of diabetes, Type 1 diabetes in which there is less amount of insulin produced, so the cells do not utilise the glucose for producing energy.

In type 2 diabetes, the cells do not respond to the insulin. A diabetic reaction can occur in both the types of diabetes.

Symptoms of Diabetic Reaction

Diabetic reactions occur if the blood glucose level gets too high or too low. The reaction due to high blood sugar is often termed hyperglycaemia while that due to decreased blood sugar is called hypoglycaemia. Some of the symptoms of a diabetic reaction are as follows.

Abnormal Blood Sugar

In the event of a diabetic reaction there is always abnormal blood sugar levels, it could be higher or lower. This indicates that the body is not responding to the insulin and a reaction is taking place.


Fatigue is a symptom of diabetic reaction, in which the patient feels shaky or unbalanced. Fatigue is a sign that the blood sugar levels have been unbalanced since some time.

Diabetics usually suffer from fatigue as they are not able to utilise the calories in the food they consume. But the fatigue of a diabetic reaction is way over the normal.


Thirst is an important indicator of diabetic reaction. Thirst is usually a sign that you have diabetes, which soon get corrected with proper diet, exercise and proper medications. When there is high glucose in the blood, the kidneys have to filter it out in the urine. They need water for this. The body is forced to withdraw fluids from tissues, causing dehydration and thirst.

Skin Changes

The body response to high or low blood sugar is often detected in the skin and is different for both. If there is high blood sugar there is hot and flushed skin. In cases of low blood sugar, the person has cold clammy skin, with cold sweats.

Mental Changes

There are some mental changes associated with a diabetic reaction. If the blood glucose levels falls down, the person may experience drowsiness, confusion and bizarre behaviour. The persons with high blood sugar may also experience confusion. The diabetic reaction could eventually lead to coma.

Increased Urination

As mentioned in thirst, the persons with diabetic reaction could also experience increased urination. The blood glucose has to passed out as urine as and when it is filtered by the kidney, resulting in increased urination.

General Symptoms

Some general symptoms of diabetic reaction include trembling, palpitations, dizziness, headache, breathing variations etc. These vary according to the blood glucose levels.

Triggering Factors

There are some triggering factors for high/ low blood glucose levels. If you pay attention to these triggering factors and take appropriate measures then the diabetic reaction can be prevented to a great extent. The triggering factors for low blood glucose level include increased exertion, excessive alcohol intake etc. High blood glucose levels are usually experienced after infections or other stresses that cause the body to reduce the uptake of glucose from the blood.
