What causes fluctuating hypertension after hernia surgery?

Condition analysis:
Hi There. I have read your query and understanding your concern for your friend.

I want to tell you generally there is no relation between hernia surgery and blood pressure. But in some patient there can be high or low BP post operatively. It will stabilize itself if there is no underlying high blood pressure issue before the surgery.

So you need not worry and wait for some more time and talk to attending surgeon.

Hopefully I answered all your queries.
Good Luck

Milk: Milk and low-fat yogurt help a lot more than to just strengthen bones. The calcium in these foods also plays a decent role in lowering blood pressure. Consume skimmed milk or low-fat yogurt on a regular basis to keep hypertension at bay. One can also go for green leafy vegetables that are high in calcium.

Cayenne Pepper: Cayenne pepper can prove to be very beneficial in treatment of mild hypertension. The spice smoothens the blood flow by preventing platelets from clumping together and accumulating in the blood. Just add cayenne pepper to your regular to get keep hypertension under control.
