What Causes Dizziness After Drinking Alcohol?
Read below
Detailed Answer:
I read your question carefully and I understand your concern.
Given the relationship to consumption of wine and the fact that you feel better now the most likely cause was alcohol related. Of course one would argue that 1/2 glass is too little, it wouldn't cause any issues with most individuals. However there are differences in metabolism in different people. In particular the low levels of an enzyme called aldehyde dehydrogenase are often blamed for feeling adverse effects such as facial flushing and dizziness even in small dosages.
Other possibilities would include an inner ear issue, a metabolic issue such as low glucose or electrolyte abnormalities or heart arrhythmia. So if symptoms reappear without alcohol as a triggering factor you should get checked, have an EKG and some blood tests. But if you are improving that probably won't be necessary.
I remain at your disposal for other questions.
