Marta mangia piano, come se le facesse male lo stomaco.

Here piano means slowly or gently, not quietly.

In Italian, piano can mean different things depending on context:

• parlare piano = to speak softly / quietly
• andare piano = to go slowly
• mangiare piano = to eat slowly

So in this sentence, Marta mangia piano means that Marta is eating in a slow, careful way.

Come se means as if.

It introduces a comparison with something that is not presented as a fact, but only as an appearance or impression.

So:

• Marta mangia piano = Marta is eating slowly
• come se le facesse male lo stomaco = as if her stomach hurt

Together: she is eating slowly, as if her stomach were hurting.

Because after come se, Italian normally uses the subjunctive.

Here, facesse is the imperfetto congiuntivo of fare.

This is very common:

• come se fosse = as if he/she were
• come se avesse = as if he/she had
• come se facesse = as if it hurt / as if it were doing

Even if the main verb is present, Italian usually uses the imperfect subjunctive after come se to express something unreal, only apparent, or hypothetical.

So:

• Marta mangia piano, come se...
  = Marta is eating slowly, as if...

and then the subordinate clause takes:

• facesse

not:

• fa (indicative, too direct/factual here)

Le means to her.

It is an indirect object pronoun referring to Marta.

The expression is:

• fare male a qualcuno = to hurt someone / to be painful for someone

So:

• le facesse male = hurt her / be painful for her

In this sentence, le refers back to Marta.

The subject is lo stomaco.

Literally, the structure is:

• lo stomaco le facesse male
  = her stomach hurt her

Italian often allows the subject to come after the verb, especially in sentences like this.

So:

• le = to her
• facesse male = hurt
• lo stomaco = the stomach

A more straight-line word order would be:

• come se lo stomaco le facesse male

This means the same thing. The original version simply places lo stomaco later.

Because Italian often uses:

• a definite article with body parts
• plus an indirect pronoun showing whose body part it is

So instead of saying:

• il suo stomaco = her stomach

Italian very naturally says:

• le ... lo stomaco
  literally: to her ... the stomach

This is extremely common with body parts:

• Mi fa male la testa = My head hurts
• Gli fanno male le gambe = His legs hurt
• Le facesse male lo stomaco = Her stomach hurt

Using il suo stomaco is possible in some contexts, but here it would sound less natural.

Fare male is a very common expression meaning:

• to hurt
• to cause pain
• to be painful

Examples:

• Mi fa male la schiena = My back hurts
• Ti fa male il dente? = Does your tooth hurt?
• Le facesse male lo stomaco = Her stomach hurt

So in this sentence, facesse male is not literally about doing bad. It is the fixed expression fare male = to hurt.

Yes, absolutely.

• come se le facesse male lo stomaco = as if her stomach hurt
• come se avesse mal di stomaco = as if she had a stomachache

Both are natural. The original sentence focuses more directly on the stomach hurting, while avere mal di stomaco is another common way to express stomach pain.

So the two versions are close in meaning, but not identical word-for-word.

The comma separates the main clause from the come se clause.

• Marta mangia piano = main statement
• come se le facesse male lo stomaco = comparison clause

This comma is very natural in writing because the second part adds an explanatory comparison: she eats slowly, as if her stomach hurt.

You may sometimes see punctuation used a bit differently depending on style, but the comma here is standard and helpful.

It can be either, depending on context.

Mangia is the present indicative of mangiare, and in Italian the present can express:

• something happening now
• a habitual action
• a general description

So this sentence could mean:

• Marta is eating slowly... or
• Marta eats slowly...

Without more context, both are possible.

Both can mean slowly, but piano is often more natural and common in everyday speech.

Compare:

• Marta mangia piano = very natural, conversational
• Marta mangia lentamente = also correct, but a bit more formal or neutral

Piano often suggests doing something carefully, gently, or without haste. In a sentence about eating because of stomach pain, it fits very well.

Yes, you may see it without the comma, especially in less formal writing.

However, with the comma, the sentence is clearer and more standard:

• Marta mangia piano, come se le facesse male lo stomaco.

The comma helps show that the second part is an added comparison, not part of the basic action.

So:

• with comma = clearer, more polished
• without comma = still understandable

Yes, usually.

• lo stomaco = the stomach, more anatomical / neutral
• la pancia = belly / tummy, more everyday and less technical

So:

• le facesse male lo stomaco sounds neutral and standard
• le facesse male la pancia would sound a bit more colloquial

Both can be correct, but stomaco fits well in this sentence.

Yes, that is a good literal way to understand it.

A very literal breakdown is:

• le = to her
• facesse male = were hurting / hurt
• lo stomaco = the stomach

So literally:

• as if the stomach were hurting her

Natural English would usually be:

• as if her stomach hurt
• as if she had a stomachache

But the literal structure is useful for understanding the Italian grammar.
