Se la pressione resta alta, la dottoressa mi consiglia di fare altre analisi.

Resta alta means stays/remains high, not just is high.

So:

• La pressione è alta = the blood pressure is high
• La pressione resta alta = the blood pressure remains/stays high

In this sentence, the idea is not simply that the pressure is high at one moment, but that it continues to be high. That is why restare is a good choice.

You could also hear rimane alta, which is very similar.

Italian often uses the present indicative in both parts of a real or likely condition.

Here the sentence means something like:

• If the blood pressure stays high, the doctor advises me to do more tests

This is a normal real condition, so Italian uses:

• se + present
• present in the main clause

That is different from English, where we also often use the present in both parts of a general or likely condition:

• If it stays high, the doctor advises me...
• or more naturally in some contexts: If it stays high, the doctor will advise me...

Italian can use the present more broadly in this kind of statement.

Italian uses the definite article much more often than English.

So:

• la pressione = the blood pressure
• la dottoressa = the doctor

With professions and titles, Italian often keeps the article where English might not focus on it as much.

Also, la dottoressa here is a normal noun phrase meaning the (female) doctor. It is not being used as direct address. If you were speaking to her, you might say:

• Dottoressa, ho una domanda. = Doctor, I have a question.

But in the sentence given, she is being talked about, so la is expected.

Mi means to me here.

So:

• la dottoressa mi consiglia... = the doctor advises me...

It is an indirect object pronoun. In full form, you could think of it as:

• La dottoressa consiglia a me...

But Italian normally uses the unstressed pronoun:

• mi = to me
• ti = to you
• gli / le = to him / to her
• ci = to us
• vi = to you all
• gli = to them

And these pronouns usually go before the conjugated verb:

• Mi consiglia
• Ti dice
• Ci parla

After consigliare, Italian commonly uses di + infinitive when saying that someone advises someone to do something.

Pattern:

• consigliare a qualcuno di fare qualcosa
• to advise someone to do something

So:

• La dottoressa mi consiglia di fare altre analisi = The doctor advises me to do / to have more tests

Here is the structure:

• la dottoressa = subject
• mi = to me
• consiglia = advises
• di fare = to do
• altre analisi = other/additional tests

This is a very common Italian pattern:

• Mi consiglia di riposare. = She advises me to rest.
• Ti consiglio di aspettare. = I advise you to wait.

Yes, but the meaning and structure shift a little.

Compare:

• La dottoressa mi consiglia di fare altre analisi. = The doctor advises me to do/have more tests.

• La dottoressa mi consiglia altre analisi. = The doctor recommends other/additional tests to me.

The original sentence focuses on the action of undergoing the tests, so di fare is very natural.

Without di fare, the focus is more directly on the tests themselves as the thing being recommended.

Literally, yes: fare analisi is to do analyses/tests.

But in medical English, we would often translate it more naturally as:

• to have more tests
• to undergo more tests
• to get more tests done

Italian often uses fare in places where English chooses a more specific verb.

So although fare altre analisi literally looks like do other analyses, the natural meaning is usually have additional tests.

Altre means other, more, or additional, depending on context.

Here it suggests that some tests may already have been done or considered, and the doctor is advising additional tests.

Grammar:

• altro = other / another
• feminine plural = altre

Because analisi is feminine plural here, the adjective must agree:

• altra analisi = another test/analysis
• altre analisi = other/additional tests

Because analisi is one of those Italian nouns whose singular and plural have the same form.

So:

• un’analisi = one test / one analysis
• due analisi = two tests / two analyses

You understand whether it is singular or plural from:

• the article
• the adjective
• the verb
• the context

In this sentence, it is clearly plural because of altre:

• altre analisi = additional tests

Not altra analisi, which would be singular.

Dottoressa is the feminine form of dottore.

So:

• il dottore = the male doctor
• la dottoressa = the female doctor

Italian usually marks grammatical gender clearly in job titles and professions, especially when referring to a specific person.

Since the sentence uses la dottoressa, we know the doctor is female.

No. Here se is followed by the indicative: resta.

That is normal in a real condition like this:

• Se la pressione resta alta...

Italian does not automatically use the subjunctive after se. In fact, in ordinary conditional sentences, se commonly takes the indicative.

Examples:

• Se ho tempo, vengo. = If I have time, I’m coming.
• Se piove, restiamo a casa. = If it rains, we stay home.

So se + indicative is exactly what you expect here.

Yes.

You could say:

• La dottoressa mi consiglia di fare altre analisi se la pressione resta alta.

That is still correct.

When the se clause comes first, Italian usually writes a comma:

• Se la pressione resta alta, la dottoressa...

When the main clause comes first, the comma is often omitted:

• La dottoressa mi consiglia di fare altre analisi se la pressione resta alta.

Both orders are natural; the version with se first gives a bit more emphasis to the condition.

Yes, in this context la pressione normally means blood pressure.

By itself, pressione can mean pressure in a general sense too, but in medical contexts:

• avere la pressione alta = to have high blood pressure

So the sentence is naturally understood as talking about blood pressure, not pressure in some abstract or physical sense.
