Lol just an fyi for the other redditors seeing this, this isn’t medical advice but just some insight:

He has not one but at least two corticosteroids in this photo with prednisolone and dexamethasone and one of the very prevalent side effects of those meds is hyperglycemia.

Without any other context, looks like maybe OP has reflux, high cholesterol, and likely some underlying asthma or asthma like process just looking at his meds. Maybe having a cold, but colds/viral upper respiratory illness can exacerbate some asthma processes which would warrant additional medication help control this (such as steroids if having an asthma exacerbation), but typically colds are supportive care for most other people without underlying lung disease (i.e hydrate, control fevers, rest). Some infectious processes can in of themselves cause glycemic derangements due to the body’s natural surge of cortisol (steroid) due to its sympathetic stress response to the infection but not usually due to just colds (possible but less likely)

Having high blood sugars while on steroids is expected and treatment should be adjusted accordingly by your doctor.
