اذا حسيت بدوخة، لازم تروح عالعيادة.

A natural Levantine-style pronunciation is:

iza ḥassēt b-dōkha, lāzem trūḥ ʿal-ʿiyāde

A few notes:

• اذا = iza
• حسيت = ḥassēt
• بدوخة = b-dōkha or sometimes b-dawkha, depending on region
• لازم = lāzem
• تروح = trūḥ
• عالعيادة = ʿal-ʿiyāde

Regional pronunciation can vary a bit, but this is a good model.

Yes, in more careful spelling, it is usually إذا.

In everyday writing, especially in dialect texts, people often simplify spelling and leave out some hamzas or other formal spelling details. So:

• إذا = more standard spelling
• اذا = very common informal spelling

This is normal in Levantine chat, subtitles, and casual writing.

This is a very common Arabic pattern.

In Levantine, after إذا, the past form can be used for a future or possible condition. So:

• إذا حسيت بدوخة literally looks like if you felt dizziness
• but it really means if you feel dizzy or if you happen to feel dizzy

This is not strange in Arabic; it is just how conditional sentences often work.

If you said:

• إذا بتحسّ بدوخة

that would sound more like if you tend to feel dizzy or if you are feeling dizziness in general / habitually, depending on context.

Here, بـ is a preposition attached to the noun.

• دوخة = dizziness
• ب + دوخة = بدوخة

With the verb حسّ, Arabic often uses بـ to express feeling a sensation:

• حسّ بدوخة = felt dizzy / felt dizziness
• حسّ بألم = felt pain
• حسّ بتعب = felt tiredness / felt tired

So this is a very useful pattern:

• حسّ بـ + noun

لازم usually means:

• must
• have to
• need to
• sometimes should, depending on context

In this sentence, لازم تروح means something like:

• you need to go
• you should go
• you must go

A very important grammar point:

لازم does not change for person or gender.
You keep لازم, and the verb after it shows who the subject is.

Examples:

• لازم أروح = I need to go
• لازم تروح = you need to go
• لازم يروح = he needs to go

Because Arabic often leaves the subject pronoun out when the verb already shows it.

So:

• تروح already tells you the subject is you or she, depending on context
• حسيت also helps make it clear that the sentence is talking to you

You could add إنت for emphasis:

• إذا حسيت بدوخة، إنت لازم تروح عالعيادة

But normally, it is not necessary.

This is very common in Arabic and is something English speakers have to get used to.

تروح here is the form used for you, masculine singular, in Levantine.

So this sentence is addressed to one male.

Other forms would be:

• to one male: إذا حسيت بدوخة، لازم تروح عالعيادة
• to one female: إذا حسيتي بدوخة، لازم تروحي عالعيادة
• to a group: إذا حسيتوا بدوخة، لازم تروحوا عالعيادة

So both the first verb and the second verb change to match the person being addressed.

عالعيادة is a contraction:

• عـ = a shortened spoken form of على
• العيادة = the clinic

So:

• عـ + ال becomes عال
• عالعيادة = to the clinic

This kind of contraction is extremely common in Levantine:

• عالبيت = to the house / home
• عالمدرسة = to the school
• عالطريق = on the road / on the way

Also, with the verb راح / يروح, Arabic uses على to mean go to:

• راح عالعيادة = he went to the clinic
• لازم تروح عالعيادة = you need to go to the clinic

The letter ع is one of the sounds English speakers usually find difficult.

In عالعيادة, you hear it twice:

• ʿal-ʿiyāde

It is a deep throat sound made by tightening the throat slightly. It is not exactly like any normal English sound.

A practical tip:

• At the beginner stage, it is more important to recognize it than to make it perfectly.
• If your pronunciation is approximate, people will usually still understand you.
• Listening and repeating native audio is the best way to improve it.

So do not worry if ع feels hard at first. That is completely normal.

Yes, this is clearly colloquial Levantine.

Some Levantine features here are:

• حسيت instead of a more formal verb like شعرت
• لازم as a common spoken way to say must / need to
• تروح instead of تذهب
• عالعيادة with عـ instead of formal إلى

A Modern Standard Arabic version could be:

إذا شعرتَ بدوار، يجب أن تذهب إلى العيادة.

So the sentence you were given is the kind of Arabic you would hear in everyday conversation in the Levant, not formal news-style Arabic.
