52 years old female. 3 months back had fever and illness. Once suddenly became unconsiousness by fainting for few seconds and had heavy breath. Blood test has been done, all are normal except random blood sugar was 60. Doctor said it was due to low blood sugar. Later recovered from fever and after that nothing like that happened. Can fainting happen during ill ess due to low blood sugar and can blood sugar become low during medications. She is not diabetic otherwise
