De verdad me preocupa mi salud.

Because preocupar works like gustar in this kind of sentence.

In De verdad me preocupa mi salud, the thing that causes the worry is mi salud. So grammatically:

• mi salud = the subject
• me = to me
• preocupa = worries

A very literal breakdown is:

• Mi salud me preocupa = My health worries me

English usually says I’m worried about my health, but Spanish often expresses it as My health worries me.

So yo preocupo would mean I worry (someone/something), which is a different structure.

Me is an indirect object pronoun here, meaning to me.

So:

• me preocupa = it worries me
• te preocupa = it worries you
• le preocupa = it worries him/her/you (formal)

In this sentence:

• De verdad me preocupa mi salud
  = My health really worries me
  = I’m really worried about my health

Even though English does not say to me here, Spanish does.

Because the verb agrees with mi salud, which is singular.

• mi salud = singular
• therefore: preocupa

Compare:

• Me preocupa mi salud. = My health worries me.
• Me preocupan mis problemas de salud. = My health problems worry me.

So the verb agrees with the thing causing the worry, not with me.

Yes. Spanish allows some flexibility.

These are all possible:

• De verdad me preocupa mi salud.
• Mi salud de verdad me preocupa.
• Mi salud me preocupa de verdad.

The most neutral version here is the original one. Putting de verdad in different places changes emphasis slightly, but not the basic meaning.

Spanish word order is often more flexible than English, especially when object pronouns like me are involved.

De verdad means really, truly, or seriously.

In this sentence, it adds emphasis:

• Me preocupa mi salud. = My health worries me.
• De verdad me preocupa mi salud. = I’m really worried about my health.

It is a common, natural phrase in everyday Spanish.

Depending on tone and context, de verdad can also mean:

• really? / seriously? in conversation
• genuinely / truly

But here it is simply intensifying the statement.

Yes, absolutely. That is also natural.

• Me preocupa mi salud = My health worries me
• Estoy preocupado por mi salud = I am worried about my health

They are very close in meaning, but the focus is a little different:

• Me preocupa mi salud focuses on the thing causing worry.
• Estoy preocupado por mi salud focuses on your emotional state.

In many situations, either one would work.

If the speaker is female, it would be:

• Estoy preocupada por mi salud.

Yes. The verb can appear in two related ways:

1. preocupar algo a alguien

   • Me preocupa mi salud.
   • literally: My health worries me.

2. preocuparse por algo

   • Me preocupo por mi salud.
   • I worry about my health.

Both are correct, but they are built differently.

So:

• Me preocupa mi salud = the health is the grammatical subject
• Me preocupo por mi salud = I am the grammatical subject

For learners, the first pattern often feels strange because it is not the usual English structure.

Because this sentence uses preocupar, not preocuparse por.

Compare the two patterns:

• Me preocupa mi salud.
  No por is used.
• Me preocupo por mi salud.
  Here you need por.

That is an important distinction:

• preocupar + noun/pronoun
• preocuparse por + noun/pronoun

So por is not missing; it simply belongs to a different construction.

Grammatically, yes, but the meaning changes.

• mi salud = my health
• la salud = health in general

So:

• Me preocupa mi salud = I’m worried about my own health
• Me preocupa la salud = Health worries me / I’m concerned about health

The second one sounds more general and less personal unless context makes it clear what kind of health you mean.

Because the normal and most natural way to say my health in Spanish is mi salud.

Spanish usually uses the possessive adjective before the noun:

• mi salud
• tu salud
• su salud

Forms like la salud mía are much less common and usually only used for emphasis or contrast, for example:

• No me preocupa tu salud, sino la salud mía.

In ordinary speech, mi salud is the correct choice.

Yes, it is natural in Spain.

A speaker in Spain might also say:

• La verdad es que me preocupa mi salud.
• Estoy preocupado por mi salud.
• Me tiene preocupado mi salud.
• Últimamente me preocupa mi salud.

But De verdad me preocupa mi salud is understandable and natural, especially if the speaker wants to stress sincerity or intensity.

The pronoun changes depending on who feels the worry:

• Me preocupa mi salud. = I’m worried about my health.
• Te preocupa tu salud. = You’re worried about your health.
• Le preocupa su salud. = He/She is worried about his/her health.
• Nos preocupa nuestra salud. = We’re worried about our health.
• Os preocupa vuestra salud. = You all are worried about your health. (used in Spain)
• Les preocupa su salud. = They are worried about their health.

Notice that the verb still agrees with the thing causing the worry:

• la salud → preocupa
• los problemas → preocupan

Yes, it can, but it may sound slightly different in emphasis.

• De verdad me preocupa mi salud puts the emphasis earlier, as if you are insisting: I really am worried about my health.
• Me preocupa mi salud de verdad can sound like my health really worries me or I mean it.

Both are possible, but the original sentence is a bit more straightforward as an emotional statement.

Tone and context matter a lot with de verdad.
