light headed dizzy

[crownz88]

hello i'm a 22 yr old male, body style: slim. for the past few weeks everyday i been having episodes of light headed and dizziness. i'd say anywhere from moderate to severe, seldomly it gets so bad i'll need to hold on to something just to maintain my balance. i have a suspicion that this may be linked to malnutrition/poor diet. my income is limited, and needless to say i dont eat 3 meals a day. usually the food that i do eat is not of the healthiest. however this is not my question. im going to work on improving my diet. my question is could this be linked to anything else besides poor nutrition? thanks for your help
