Hi,
Due to loss of fluids and depletion of nutrients from
diarrhea, you developed fatigue and
restlessness. These usually developed in case of loss of fluids in body from vomiting and diarrheas.
The problem of mood swings can be due to: Change of place as environment, amount of light, temperature and culture of the place can lead to psychological changes in the body and therefore mood swings as well (Your travel history to new places and
panic attack as you mention). Another reason is from infection of
poisoning and fluid loss over long periods had impacted fluid and nutrient supply to the brain resulting mood swings.
You are advised to take plenty of liquids and soup in the diet.
Take fresh fruits and do early morning walk for fresh air.
I advise you also take
probiotic it has an overall good effect on the gut.
I suggest you also get yourself checked by a physician may be you can need some drug therapy that would be initiated after taking your proper history and examination.
Hope I have answered your query.
Let me know if I can assist you further.
Regards,
Dr. Soheel Hussain Zargar, Dentist
