thanks for writing hcm
No need to worry about your treatment .you have receieved proper treatment for complaints with loose stools and vomiting
.The reason for your weakness is because of loss of electrolytes (because of loose stools) namely sodium ,potassium etc.my advise is to take oral rehydration salt sachets twice-thrice daily so as to replenish your body electrolytes.
I would be glad to provide answers to any further queries.
Thanks for using HMC Have a good day!
