If you get a cold the body can recover on its own, while other illnesses need medication. Why?
In: Biology
In every case, your body’s immune system will try to fight the illness. Sometimes your body can do it on its own, and sometimes it needs the medicine to help it out when it’s too strong for your immune system to handle by itself. But in general, in both cases, it’s your immune system attacking it— not the illness going away by itself.
People who don’t have a viable immune system can easily die from even a cold, and other kind of weak illnesses like that. When your immune system doesn’t fight enough, diseases will live in you indefinitely until they totally take over.
