Brief Answer: What medications is he on? Detailed Answer: Hi and thank you so much for this query. I am so sorry to hear about this abnormal glucose readings that your father has had recently. In a well controlled diabetic patient like you father from the past readings, a spike in his glucose numbers raises the concern of something not going right some where. The first and most important thing to do is to investigate for a possible infection that could be responsible for this. The most common infections are urinary, lung and skin. If these are all ruled out, then his diet would need to be evaluated for any possible changes that may explain this and if nothing can justify this, then I will recommend that his drug dosages should be reviewed. Also, do you know what could have caused the low oxygen reading or is it something normal that has been happening with him? This could be the sign of a lung infection!!! In all, get him evaluated by a medical personnel for a possible infection. His diet and medications should be reviewed if no other cause is identified to be responsible for this. I wish him well. Thank you so much for using our services and feel free to ask for more information and clarifications if need be. Dr. Ditah, MD.
