Detailed Answer:
Hi XXXXXXX XXXX,
Thanks for the query. I have read it & understand your concern.
* You seem to be worried about the unprotected sex you had while you had your period.
Let me clarify in the beginnibg only that such a intercourse is not likely to cause conception / lead to symptoms like you have... For pregnancy can occur at ovulation time .. which is 14 days prior to the expected day of menstruation.)
* You work for 10 hours a day , have extensive physical activities like walking for 1.5 hours after the prolonged work, plus you do not have sufficient night's sleep.
I feel all your trouble is due to the weakness caused by your hectic routine.. disturbing your appetite, digestion( suggested by light headedness after eating, feeling like throwing up)
* So though you need to have a full health check up along with special attention to blood pressure/ eye & ear check up.This would find/ exclude other possible causes of dizziness.
-MEDICAL ADVICE: A detailed examination of digestive system/ exclusion of bowel infections/ hyper acidity & poor digestion would specify your medicinal needs to remove the cause.
- HEALTHY LIFE STYLE:
This needs to be accompanied by setting a healthy lifestyle with optimum physical work
proper nutrition with proteins, vitamins & minerals... at fixed hours
Doctor's advise & treatment as per need.
sufficient ( 8 hours )sound sleep in night providing physical & psychological rest
* You should therefore consult your family physician who will get you evaluated by examination/ investigations .. to start with treatment( with antibiotics or anthelmintic , anti amebic drugs/ antacids , digestive enzyme supplements as per need ) OR he may refer you to a ENT / EYE specialist for further management, if needful.
I hope you found the answer informative & useful Any follow up query is welcome.
Thanks.
