Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain vomiting and diarrhea can occur due to causes like bacterial infection in stomach or food poisoning,parasitic infestation,
electrolyte imbalance,
food intolerance, allergies etc..
I would suggest you to start taking Fluid Replacement Therapy that is drinking plenty of oral rehydration salts by making a solution in water..
Take a soft diet and more of probiotics like Yoghurt,rice, cereals and banana..
You can also be advised to take anti diarrhea medication like
Loperamide for diarrhea and ondensarton for vomiting..
In case if the symptoms does not improve or gets worsen
consult a Gastroenterologist and get evaluated and a thorough clinical evaluation and investigations like
blood test can be diagnostic and treatment can be done accordingly..
Hope this information helps..
Thanks and regards.
