I’m now on the 24th day off a carnivore diet and have noticed a dry blocked nose at night.
Other than that, I would say my nasal passages are generally clearer than before (although this might be wishful thinking).
My left nostril has always been easily blocked though.
I know this is pretty micro, but has anyone any similar experiences?
Likely you’re a little more dehydrated from before. On keto we dump a lot of sodium and you may find your more thirsty than usual. Make sure keeping your fluids up and adding back salt. Not sure if we have the exact same problem, but may be similar - I have clear air upper passages but crusty/blocked right inside the front of the nose, especially first thing in the morning. Sorts its self out with shower and morning coffee/fluids. If really annoying you can use a neutral nasal gel from the drug store to rub into your nose or do a neti pot (or similar) nasal rinse. True, not the worst problem in life to have, but it can get a little tender up there for us sensitive types.
