I think I would call that one of the latest signs. The signs mentioned in the article are much earlier indicators of chronic stress conditions, since they also work on someone who is somewhat in denial about their condition. Speaking from personal experience, the biggest problem is that you really don't want to admit to yourself or to others that you're suffering from chronic stress. Indigestion, lack of sleep, headaches, frequent colds, etc. are all symptoms, but people will get several these and still treat them as if they were separate issues, rather than being caused by a continuous release of cortisol and other stress hormones: "Oh I can't sleep, better start using melatonin!" "Oh I'm constipated, better eat more fibre and start the day with yoghurt!" "Oh I have a headache again, better take some paracetamol and drink lots of water!"
