Learn Spanish (Latin America): Estás enfermo. Deberías ir al médico. - You are sick. You should go to the doctor.

Deberías is the conditional form of the verb deber (to must / to owe). While debes ir sounds like a strong obligation or command ("you must go"), using the conditional softens the tone to mean "you should go." It is the most common way to give polite, helpful advice in Spanish without sounding bossy.

Why do we use Estás instead of Eres for "You are sick"?

We use estar because illness is a temporary physical condition or state, which is how we generally talk about health in Spanish. If you used ser and said eres enfermo, it would imply being a "sick" person as a permanent trait or characteristic (such as being chronically ill or mentally disturbed).

Why is it al médico and not just a médico?

In Spanish, you usually need the definite article el (the) when talking about going to see a professional, just like in English when you say "going to the doctor." The verb ir (to go) requires the preposition a (to) for destinations, and a combines with el to form the mandatory contraction al.

Could I say al doctor instead of al médico?
