Identify Symptoms and Indications of Diabetes

Diabetes symptoms of the dreaded disease often go undetected because people are unable to identify them. This article discusses all the diabetes symptoms in much detail. It becomes easier to control diabetes if symptoms are identified on time and reported to the doctor for proper analysis and treatment.

The diabetes symptoms in Type I and Type II of the disease are not easily distinguishable since blood sugar in both types of diabetes becomes high due to either decreased insulin or in some cases lack of production of insulin. Diabetes symptoms might sometimes occur due to insulin resistance by the body too. In all the cases there is insufficient glucose in the cells, while the glucose level in the blood is in excess.

In Type I diabetes the glucose levels are high because of absence of insulin, as the cells that produce insulin are either damaged or destroyed. In Type II diabetes on the other hand cells in the body become resistant to insulin. In both cases cells are deprived of glucose required for proper functioning; leading to symptoms of diabetes.

The most common symptoms of diabetes are discussed below –

Polyuria or Frequent Urination

Increased glucose levels in diabetes patients cause the body to produce excess urine. This is the body's way of expelling excess glucose present in the blood. When insulin is absent in the body or is inefficient the kidneys fail to filter glucose and send it back into the blood stream. Kidneys become beleaguered in an attempt to filter the glucose and automatically begin pulling out additional water from the blood for diluting the glucose. As a result the bladders remain constantly full and those suffering from diabetes feel the need to relieve frequently. This in turn causes dehydration since the body expels huge quantities of water due to increased urination. Excessive urination is the most common diabetes symptom.

Polydipsia or Excessive Thirst

Perpetual thirst is another symptom of diabetes. As the glucose levels increase in the blood the body reacts to the excess by attempting to dilute it. Thirst becomes unappeasable since the glucose level in the blood is high and the brain sends signals to dilute it; leading to perpetual thirst. The kidneys on the other hand continue to take water from the blood in their attempt at diluting the glucose. As a result the bladders collect excessive water and the urge to pass urine persists the whole time. This becomes a vicious cycle with diabetes patients continually feeling the need to quench their thirst and ease themselves.

Polyphegia or Increased Hunger

Insulin is actually a type of hormone and one of its functions is to rouse hunger. When blood glucose levels in the body are higher than normal, the body automatically starts manufacturing extra insulin in a bid to control the high glucose levels. The increased insulin levels cause undue hunger pangs in those afflicted by diabetes. An individual who feels hungry even after having substantial meals must look at the hunger pangs as diabetes symptom.

Sudden Weight Loss

Sudden weight loss can also be attributed to diabetes symptom. However, weight loss is more perceptible in Type I diabetes. In this type of diabetes the pancreas stop producing insulin due to an autoimmune reaction that destroys the cells which produce insulin. With no insulin available the cells are deprived of sufficient glucose and the body looks for alternative sources for energy. As a result the body begins breaking down fat and muscle tissue to meet its energy needs. However in Type II diabetes the weight loss occurs gradually due to an increase in insulin resistance.

Hyperosmolar Hyperglycemia Nonketotic Syndrome or Blurred Vision

Blurry vision is one of the most common diabetes symptom in Type I diabetes patients. The condition occurs due to excessive amounts of water drawn by the kidneys for diluting the glucose. The water is drawn from tissues in the body including those in the eyes. The lack of fluid or moisture in the eye obstructs proper focusing which hampers eye sight and causes fuzzy vision.

Neuropathy or Numbness or Prickling in Hands, Feet and Legs

These are diabetes symptoms that transpire progressively as the condition deteriorates due to constantly high glucose levels in the blood, which damage the nervous system. This predominantly affects the extremities in the diabetes patient; such as hands, feet and legs, giving a feeling of numbness or tingling. In individuals who do not get regularly get screened for diabetes the condition goes undetected for years with nerve damage occurring without the patient realising it. The nerve damage is reversible and can be controlled by managing the blood sugar count.

Extreme Fatigue and Weariness

The food we eat is converted into glucose, which moves in the blood stream where insulin assists in its transition to provide the body energy. However, with diabetes sufferers the glucose remains in the bloodstream in the absence of insulin or when cells stop responding to it. The inadequacy of cells to metabolize glucose leads to the body utilizing the reserve fat stores for meeting its energy requirements. The body expends more energy into breaking down fat for energy than glucose. This creates a negative calorie syndrome which results in low energy levels and a feeling of tiredness and lethargy. Acute and unexplained exhaustion can be recognized as a diabetes symptom.

Impaired Healing of Lesion and Wounds

Diabetic patients often find wounds and injuries not healing quickly. This diabetes symptom can be quite dangerous. The reason behind this is high sugar levels which prevent white blood cells from thriving. White blood cells are critical for the immune system. When the production of these cells is disturbed, the healing of wounds is invariably affected. Diabetes is also known to thicken blood vessels which interrupt proper blood circulation leading to wounds not healing.

Susceptibility to Infections

The unstable blood sugar levels cause the immune system to stop functioning properly. This creates diabetes symptoms that cause recurrent skin infections in diabetes patients. Diabetes patients are prone to bacterial and fungal infections. They also have a tendency of contracting urinary tract infections easily.

Increased Tetchiness

Diabetes patients are often petulant and easily irritable. The diabetes symptom is linked to high blood sugar which adversely affects the glucose supply to different organs in the body, particularly the brain. Lack of glucose in the brain can deprive individuals of energy, leading to exhaustion which causes bouts of short temperedness.


The above mentioned diabetes symptoms are linked to the disease. Individuals experiencing any of these indications over a consistently long period of time need to consult their doctor to determine the exact cause of the symptoms. Diabetes can be managed with medication, diet, exercise and a few life style changes. It is no longer a disease to be dreaded as it can easily be controlled.
