My dad's (87) cheeks are showing red for the last 2-3 days. What could be the cause?

Red wine is a good vasodilator and will rosy up the cheeks. Now if you are seeing a LOT of redness, check his medications and see if they are all OK with alcohol. Make sure he is not allergic to sulfites in wine.

High blood sugar can cause flushing of the face. Could your father be diabetic? If you think it is a possibility, have his doctor test his blood sugar.

My Dad had a vasomotor instability and if he just got up, or was in the heat, he would flush red. But he was this way early on in his forties. He did also drink.

He also took sub-lingual nitro-glycerin pills for angina-early in his life. The tightness in his chest, the pain down one arm, shortness of breath, let's stop here a moment, I have to rest, he said.

How long has he been here with you in the states? Did he just arrive? Do you have notes about his current medical status, know about his medications, and what they are for? As Pam asked, allergies to wine and or sulfites? Does he have a fever, or feel ill in any other way? Has he been out in the sun, the heat, med reactions to sun, alcohol, things like that? I suspect that it could be the wine, but I'd probably have him checked out as he is 87, and there could be something else going on.
