Other Complications

Poor control of blood glucose leads to complications in certain body organs which severely affect the life of an otherwise healthy individual. The most common organs affected are:

When diabetes affects the kidneys, the condition is called diabetic nephropathy. It is caused by damage to the small blood vessels in the kidneys, causing reduced blood flow to it while impairing its functions. If the high sugars are uncontrolled for a long time, then, it can eventually lead to kidney failure. This condition is the most prominent cause for dialysis and kidney transplants.


There are no symptoms in the early stages of this complication. Yet as the severity increases, we may start feeling exhausted, may become anemic and also suffer serious electrolyte imbalances.


When diagnosed early, we can undertake several steps to reduce the progression of the disease and prevent kidney failure. The various methods of management can be control of blood glucose and blood pressure levels, using medicines properly at the early stage of and limiting the use of protein intake in the daily food consumption.


When diabetes affects the nerves of the body, it is termed as diabetic neuropathy. It is the most common complication of diabetes. The elevated blood sugar levels can either directly damage the nerves or in some cases, the damage caused to the small blood vessels can also reduce the blood supply to the nerves and may end up damaging them. If left untreated the condition can cause damage to the limbs, sensory loss and impotency in men with diabetes.


The symptoms in this condition vary widely. They are dependent on the nerves being affected. It commonly affects the limbs leading to amputation of the foot and is also a major cause for ulcers to form on feet (diabetic foot). Sensory feeling in the feet and hands is progressively reduced over time if blood glucose levels are left untreated. This is the most prominent cause for amputation, which can be prevented with early detection and treatment.


When diagnosed early, several steps help in preventing or reducing the progression of the disease. The various methods of management can be control of blood glucose and blood pressure levels and using medicines as prescribed. In addition to managing diabetes, periodic comprehensive screening for neuropathy and diabetic foot are critical to catch the condition in the early stages and prevent its progression or to prevent the condition altogether.

Heart and blood vessels

Individuals suffering from diabetes are at a higher risk of developing problems related to heart and blood vessels (also called Cardio Vascular Diseases- CVD’s) of the body.

Increased blood glucose levels can lead to an increase in the number of blood clots along with increased blood pressure and cholesterol. This commonly leads to clogging of blood vessels (called Atherosclerosis) and causes narrowing of these blood vessels. This results in reduced blood flow to vital organs like heart, brain or limbs.


Individuals with uncontrolled diabetes are prone to disorders affecting various blood vessels supplying blood to

  • muscle of the heart (causing heart attack),
  • brain (causing a stroke),
  • arms and legs or even damaging the heart muscle.

Most of these conditions are fatal and can result in death of the concerned individual.


The most important step towards prevention of CVD’s is the management of blood sugar. This can be achieved by lifestyle modifications and the regular uptake of either prescribed medications and/or Insulin.

Oral and dental health

Individuals with diabetes are generally prone to a number of oral and dental problems, if the blood sugars are not adequately managed. These problems are also known cause CVD’s. In case of people with diabetes, the immunity is weakened and this is primary responsible for causing the multiple oral and dental problems.


The main manifestation of diabetes in the mouth is the swelling of gums (Periodontitis). This often leads to loss of teeth and can also lead to CVD’s. In cases where blood glucose are left uncontrolled, it often causes

  • decay of teeth,
  • fungal infections of the mouth (called candidiasis),
  • diseases where the body’s immune system attacks the body cells (eg: Oral Lichen Planus),
  • burning sensation of the mouth,
  • impaired function of saliva,
  • dryness of the mouth and impairment of taste


For good oral and dental health, people with diabetes needs to maintain good oral hygiene. In addition to it, regular screening and a yearly follow up are a must to either prevent or manage such conditions.
