Mostly agreeing with this point here.But I feel the need to have clarified, what kind of mental and physical health issues are you referring to?Cause I'd have to argue against that depending on what you mean.

Without giving another massive answer, and without listing tonnes of conditions: 
Physical issues would obviously include ones where there is a moderate chance that the mother and/or child might die. I would include this to the point where there is also severe handicapping (e.g. one or both becoming handicapped). Something that's treatable or manageable (e.g. a loss of an arm, etc.) should not constitute an abortion. 

Psychological issues would include where due to genetics (etc.) there is a moderate chance of the child developing a severe issue. I do not know much about this though, so my opinion is limited - if what I just said is bullshit then by all means point it out. Moreover, where there is a chance due to the circumstances surrounding the birth and possible upbringing (e.g. like in the Fritzle case) that the child or mother may suffer further psychological trauma; if from a young age you found out that your father was your rapist grandfather, you might become pretty fucked up. 

By mental issues I mean the more severe ones, such as (in the most extreme case, and please forgive my wording,) vegetation. However things like autism I do not believe should constitute abortion in the majority of cases.
