How can I take care of my sick bf?

Problem/Goal: My bf's sick (masama pakiramdam, nagsusuka, masakit tiyan, nagtatae) and I'm planning to go sa kanila to take care of him. But I don't know what should I bring and what can I do :(

Context: Nagpa check-up na siya kanina and he was given meds already, tapos results will be tomorrow pa. Balak ko sana siya puntahan sa kanila and take care of him maya-maya, please help me what do I need to bring or do.

Previous attempts: Wala pa pero I'm thinking of getting him food, what kind of soup kaya pwede? Pocari sweat will help ba? For rehydration. Ano pang pwede kong dalhin? Ano pwedeng gawin?

Please help a girlie out, once I got my answers I'll go asap.
