Thanks for query.
It seems you might got hypoglycema i.e. low blood sugar
level giving rise to this problem.
When you feel like dizziness
,perspiration and feeling like faint,these are the symptoms of hypoglycemia
At this time take few sugar crystals or lime water with sugar or few chocolates.
Always carry few chocolates or sugar quebes in your pocket while going out.
Always keep your diabetic card mentioning your name,address and cell phone number of your residence.
Ok and bye.
