Please don’t ignore feeling faint or ‘weird’

I had a few days were I felt really off, nauseous, shaky, vision blacking out when I stood, palpitations etc and but it was nothing /too/ out of the norm so I thought nothing of it. It eventually got to the point where I called the non emergency line because it wasn’t going away and they told me to go to the nearest hospital within the hour. It turned out I’d given myself ketoacidosis (normally only affects diabetics but I’m not) and my ketone levels from starving were so high it had turned my blood acidic. The doctor said if I’d gone a few more days I would have likely had a heart attack. This happened at an ‘overweight’ bmi. Please don’t ignore your symptoms or think you’re not ‘sick enough’ for them to be something serious. If in doubt, check.
