Are indian women weaker/more vulnerable physically?

Most women I've know, friends or work colleagues, a lot of them face different types of medical issues. Some are allergic, some have reproductive health issues, some catch cold or fever very easily, and there are many with issues like anxiety etc. In several occasions I've seen women in my family and few friends as well faint due to weakness or other reasons. Are indian women not physically fit? Or am I just looking at a bad sample?
