Hello
I appreciate your concern
Looking at your description this could be food
poisoning or gut infection either viral bacteria or protozoa
I would like further information to guide you better like
Your age and relevant medical history
Is it associated with pain in abdomen or vomiting?
You should continue with all your medication
Have adequate fluid intake including
ORS or fruit juice to avoid
dehydration and electrolytic imbalances, otherwise your blood pressure may fall as you are taking anti hypertensive Losartan
You may require a course of antibiotics under supervision of your doctor
Meanwhile have probiotics, curd, yogurt or banana as a home remedy
Hope this helps you
Please write back to me with all the details I will definitely help you in best possible way
Best wishes
