Why Diabetics Sweat?


  • Continuous Fluctuations in Blood Sugar Levels— Unhealthy lifestyle choices even after the diagnosis of diabetes or improper administration of diabetes can lead to incessant fluctuations in blood sugar levels leading to excessive sweating.
  • Autonomic Neuropathy— If not treated on time or not maintained within the normal range, the diabetic condition may worsen and damage the autonomic nervous system. This may affect the patient’s blood pressure, heart rate and perspiration. The prolonged state of uncontrolled blood sugar levels leads to autonomic neuropathy. Nerve damage due to diabetes is a painful experience and at times, results in hampered functioning of the body.
  • Disorder Treatments— Medical conditions, such as hypoglycaemia or autonomic neuropathy lead to various complications, one of them being excessive sweating. Immediate treatment after diagnosis of these medical conditions controls blood glucose levels from going haywire, thus preventing sweating in diabetics.

When Diabetics should seek Medical Help for Sweating


  • If you are frequently experiencing cold sweat at night and often end up spending a sleepless night due to excessive sweating.  
  • When sweating is no more confined to your head, face, armpits and groin, but the entire body, it is an indication that you need medical help.     
  • If you are experiencing asymmetrical sweating .i.e, one of your armpits sweats, but the other doesn’t, you need to seek medical aid.
  • Diabetics may experience change in their sweating pattern. For instance, before treatment the patient may have sweat excessively, but after treatment, not as much.  The change in pattern can be due to fluctuating blood sugar levels or in response to a certain food. 
  • Some diabetics sweat excessively after eating. This may indicate nephropathy, peripheral neuropathy and dysautonomia. [Read: Why Diabetics Sweat after Eating]
