Diabetes is a medical condition which hinders the ability of the pancreas to produce insulin, a hormone which regulates the glucose levels in the blood stream. Without an adequate supply of insulin, diabetes can cause extreme rise and fall in the blood sugar levels.

Diabetes also causes degeneration of the eye by affecting the blood vessels around the eye due to an increase in the viscosity of blood. This leads to blurred vision, accompanied by dizziness. Moreover, high sugar levels cause the veins and arteries around the heart to clog, making the flow of blood rich with oxygen, difficult and slow. This in turn causes dizziness or nausea.

Dizziness and Blood Sugar Levels:

Insulin is the hormone responsible for the absorption of glucose from the blood by the body cells. If you are diabetic, your pancreas is unable to produce enough insulin resulting in an alarmingly high amount of glucose to be present in your blood. This condition is medically termed as hyperglycaemia. Also, diabetic patients do not necessarily have elevated blood sugar levels all the time. Sometimes their blood sugar levels fall down to steep low levels. This condition is termed hypoglycaemia.


If a person suffers from hyperglycaemia, he or she has a dysfunctional pancreas, which means severe insulin deficiency, leading to excessive amount of glucose levels in the blood. This makes the blood thick and leads to onset of some early symptoms, such as dizziness or light-headedness followed by fatigue and lethargy. The body may also suffer from dehydration due to this and the patient often loses consciousness. Sometimes, the acid-base balance of the body varies too, which is termed as diabetic ketoacidosis. Hyperglycaemia also leads to anaerobic metabolism. Diabetic ketoacidosis and anaerobic metabolism can also result in vertigo and make the person lost consciousness suddenly.  Apart from these, acutely high blood sugar levels can even lead to coma.


Hypoglycaemia is a special case of diabetes, where a person experiences low blood sugar levels due to excessive dieting or consumption of medicines or insulin shots. In order for the brain to carry out its functions properly, it needs a sufficient amount of glucose. Low levels of sugar in blood, hampers the proper functioning of the brain and leads to weakness, sweating and in case of excessive deficiency of glucose, it may lead to dizziness.

Dizziness is experienced by people suffering from both hypoglycaemia and hyperglycaemia. Sometimes very high levels or low levels of blood sugar throw you out of balance, if you try to stand up from a sedentary position or cause unconsciousness.

How Diabetics can prevent Dizziness

Dizziness is a consequence of very high or low levels of diabetes. As we all know prevention is better than cure, so here are a few things you can do to avoid dizziness.

  • Get your blood sugar levels checked regularly to avoid dizziness or nausea.
  • Make exercise a part of your daily schedule. Even a brisk walk of 30 minutes can burn enough calories to regulate your blood sugar levels.
  • Eat a balanced and high fibre diet comprising all the vital nutrients needed by the body. Eating excess or inadequate quantities of food can wreck havoc to your blood sugar levels.
  • Take your medicines on time and only in the prescribed amount. Excessive use of certain medicines sometimes causes hypoglycaemia, which in turn leads to dizziness.
  • Avoid foods that are high on sugar, salt or carbohydrates. Even a cup of coffee, a glass of cola can cause acute increase in your blood sugar levels.
  • Make certain lifestyle changes like replacing your usual cup of coffee with green tea, using the stairs instead of elevators, joining a gym, yoga or dance class.


Dizziness is an early symptom of diabetes and closely associated with your poor control of your high/low blood sugar levels. You should consult your doctor whenever you start feeling dizzy because it might be a signal that your sugar level is critically elevated or low.
