I do not see any ambiguity in the source text.

@lirka:
#2 is correct.

Since these two answers are identical, can someone tell me whether this really needed references? IMO, it doesn't - it appears to be merely a matter of comprehension.

You are right; we should not do their thinking for them and assume something not stated in the text.
One question: what distinction are you making between detrimentally and adversely, the other answer?

Let her doctor figure it out. You correctly point out an ambiguity, but your job as a translator is merely to reproduce the same ambiguity in English. A translation should not contain more information, or more specific information, than the original. I agree with Ellen Kraus' solution "may detrimentally affect". However I don't understand why she identifies her translation proposal with your option 2. On the contrary, "may detrimentally affect" fails to clear up the issue, which is exactly what you should do.
