Nose bleeds can the weather trigger them?

I think it was more likely that the blood thinners were the culprit and not the weather.

No idea about medication, but here in Devon atmospheric pressure certainly rose at the end of the month. We are having a run of calm, but cold days. I think it this can correlate with raised blood pressure, but I'm no medic.

It happened to me with blood thinner, the hospital changed my prescription, nothing to do with the weather.

Hay fever can cause them

Same . My son’s hayfever caused it. He had it cauterised but it didn’t help much . He is 49 now. I wonder if he still gets it …..must remember to ask him

A few years ago I went through a period where I had repeated nosebleeds, some really heavy. I am absolutely convinced they were caused by stress, as I was going through an extremely stressful time of my life, and when the cause of the stress went away the nosebleeds stopped.

Yes, I would think it was blood thinners. I'm on them, and dhaven't had a nose bleed, but every few days my nose will become very runny, just for a minute or two

Only ever had nose bleed once in my life. It was when I was seriously anaemic with my iron level half what it should have been.

My husband had constant nosebleeds when he first went on his blood thinners, they adjusted the dosage but he still gets the odd one if he blows his nose hard in the morning.

In the past, I have been hospitalised twice with chronic nose bleeds.

It was eventually decided by doctor that it was caused by raised blood pressure.

Have been on medication since then and never had another bleed.

My daughter had one horrendous nose bleed when we stepped out of our airconditioned car in Yuma, felt like stepping into an over it was sooooo hot. Never had one before or since.
