What Could Cause Dizziness And Loss Of Appetite?

My son is 24 years old. He is feeling dizzy and extremely tired. 3 days ago he fainted after feeling like he was going to throw up. He was able to eat something, but then felt chilled and exhausted. He seemed to do better for a couple of days, and now today is starting to feel the same symptoms but has no appetite. My son has been very healthy and has never had a serious health issue. He is a college student and is not currently living at home. I've suggested that he go to his student health clinic, but wondered what could cause the dizziness, loss of appetite. I am concerned that he may faint while driving to/from class.

Hello and welcome to HealthcareMagic.

Feeling dizzy and ill is not a very specific finding, meaning it could be a manifestation of many different conditions, so more info or tests might be necessary. Also it is not clear since when have the issues appeared and whether you have had any tests.

One possibility for light-headedness would be anemia, which commonly manifests with dizziness andtiredness.

Heart rhythm and function abnormalities would also lead to insufficient blood supply to the brain and other organs so would also justify those symptoms.

Another possibility would be metabolic alterations, like diabetes, altered kidney or liver function, electrolyte abnormalities. Hormonal causes like thyroid dysfunction or nutritional ones like vitamin B12 deficiencies must be considered as well.

If the symptoms have appeared only very recently it might be a simple transitory viral infection which are generally transitory and need only rest and hydration.

So I would start evaluation with some routine cheap tests to screen for anemia, infections and metabolic issues like complete blood count, erythrocyte sedimentation rate, glucose, liver and kidney function, electrolyte panel, thyroid function, vitamin B12 levels, EKG.

I remain at your disposal for other questions.
