Helsesjekken bekrefter kastreringen og ormekuren.

Because they are all in the definite singular form.

In Norwegian, instead of putting a separate word like the before the noun, you usually add the definiteness to the end of the noun:

• en helsesjekk = a health check

• helsesjekken = the health check

• en kastrering = a castration / neutering

• kastreringen = the castration / the neutering

• en ormekur = a deworming treatment
• ormekuren = the deworming treatment

So the -en here is doing the job that the often does in English.

The basic forms are:

• en helsesjekk
• en kastrering
• en ormekur

These are the forms you would usually look up in a dictionary.

The sentence uses their definite forms:

• helsesjekken
• kastreringen
• ormekuren

That is very normal in Norwegian. Definite nouns are usually marked with a suffix, not a separate article.

So:

• the health check → helsesjekken
• the castration → kastreringen
• the deworming treatment → ormekuren

English uses a separate article; Norwegian usually attaches it to the noun.

Bekrefter is the present tense of the verb å bekrefte.

So:

• å bekrefte = to confirm
• bekrefter = confirms / is confirming

In this sentence, Helsesjekken bekrefter ... means The health check confirms ...

This is standard present-tense verb use in Norwegian.

Because this is a normal subject–verb–object sentence.

• Helsesjekken = subject
• bekrefter = verb
• kastreringen og ormekuren = object

So the structure is:

Subject + Verb + Object

This is the same basic order English often uses:

The health check confirms the castration and the deworming treatment.

Yes. Norwegian very often makes compound nouns by joining words together.

Here:

• helse = health
• sjekk = check

Together:

• helsesjekk = health check

This is very common in Norwegian. English sometimes writes similar ideas as two words, but Norwegian often prefers one compound word.

Literally, it is made from:

• orm = worm
• kur = cure / treatment

So ormekur literally means something like worm treatment, and in natural English it is usually deworming treatment or just deworming.

This is another example of a Norwegian compound noun.

Because both nouns are part of the same object after the verb.

So:

• bekrefter kastreringen og ormekuren

means:

• confirms the castration and the deworming treatment

Norwegian, like English, does not need to repeat the verb here.

Compare:

• The health check confirms the castration and the deworming treatment.

You would not normally say confirms the castration and confirms the deworming treatment unless you wanted special emphasis.

In strict literal terms, kastrering is castration. But in real-life pet or veterinary contexts, it is often used more broadly in a way that English speakers might naturally translate as neutering.

So the best English translation can depend on context:

• technical/literal: castration
• everyday pet context: neutering

If this sentence comes from animal paperwork, neutering may sound more natural in English.

Yes, but the meaning would change.

For example:

• En helsesjekk bekrefter kastrering og ormekur.

This sounds more general, like A health check confirms castration and deworming.

The original sentence with definite forms:

• Helsesjekken bekrefter kastreringen og ormekuren.

refers to specific things:

• the health check
• the castration
• the deworming treatment

So the definite forms suggest that these are known or already identified procedures.

It sounds like formal or veterinary documentation. In that kind of context, bekrefter often means something like certifies, verifies, or confirms that something has been done.

So the sentence is probably not saying that the health check somehow causes those procedures. It means the health check or the examination serves as confirmation that they have been carried out.

That is why this kind of wording is common in certificates, pet passports, or veterinary records.
