Feeling lightheaded 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 the 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 is generally transitory and need only rest and hydration.

The list can go on for long, as I said those symptoms can be found in numerous conditions, only listed some of the most common ones.

So I would start the 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.

Hope I have answered your query. Let me know if I can assist you further.

Take care
