Does it is correct grammatically

[Dr. R. Saroj]

Hi friends,

Somebody wrote me in his letter:

"I will see the patient as a follow up in three months"

Is it correct?

If not what grammatical error have it and what changes should be made

Dear Saroj

Your question should read as:

'Is this sentence grammatically correct?"

Do you know the meaning of 'follow-up', Saroj?

The sentence seems OK to me.

Tom
