Proofread the sentence and Insert punctuation as required.

She reports the flare up is worse when she does not have her diabetes under control.

Answer:
I feel it doesn't need anything added to it. FINE as is! I hope!

Right again.

She reports the flare-up is worse when she does not have her diabetes under control.

Explanation:
The original sentence is missing a hyphen between "flare" and "up." The corrected sentence includes the hyphen to form the compound word "flare-up" which is commonly used in this context. Other than that, no additional punctuation is required.
