I sometimes suspect certain foods. My pressure tends to drop after eating, especially when bread is involved.
I don't have much salt in my food, but I do have a little sometimes, and I eat very few "processed" foods. Almost all my food is cooked fresh.

I wish I or my vet knew. The crazy thing is that a few hpurs later it can have climbed to 140 - or sometimes still be low!

@Petter Your vet? That's your first problem, you need to talk to an MD or an Osteopath. JK Are you on BP meds? If it's +HTZ that can cause spikes and drops. I had that problem and my doctor changed my med without diuretic. Haven't had the problem since.

@barjoe me too

I've had my medication changed and I've had my dosages adjusted by my vet quite a few times. My pressure has twice had me in hospital when it went up to 227. I now have emergency tablets for that scenario. I haven't been that high for over a year now, but I have hit 190 a few times, at which point I take an extra Losartan and have a siesta. I also drink plenty of liquids, usislly water, milk or decaffeinated tea.

@Petter Losartan and all ARBs work by regulating your potassium level. Don't take high levels of potassium or foods that are high. Don't use salt substitute, that will do it. Strawberries bananas.avocados. I've been told not to use grapefruit either

I had taken none at all this morning. Last night I took 50mg of Losartan. It's truly erratic.

With or without some soap in it?

@Petter maybe freshlemon or lime?

If low is your baseline, you won't feel it. But if you're baseline is high and you drop like that, dizziness is common. My baseline has always been low. Every time I've gone for surgery, anesthesia freaks out until they look at my history.

Same arm, no meds between them. BUT I did have a currant bun and decaffeinated coffee shortly after the higher reading. Now, after another 3 hours, it's back to 120.
