Surgeries come with risks, which include death. Surgery can significantly lower your vitamin D, so if you have surgery and you’re deficient, you could be putting yourself at risk.

If you’re low in vitamin D, your blood pressure can go up. Vitamin D is one of the best remedies for high blood pressure because it increases nitric oxide, which helps vasodilation in the arteries.

Vitamin D supports your immune system, helps prevent infection, and reduces inflammation. It also helps reduce cardiovascular complications after surgery. Some people take 100,000 to 300,000 IU of vitamin D before surgery!

If you don’t have enough vitamin D, your muscles can weaken, which increases your risk of falling after surgery. Post-operative inflammatory indicators increase by 200% if you’re low in vitamin D.

Vitamin D can increase antimicrobial peptides by 4000%! This compound helps your immune system kill microbes and dramatically reduces the risk of postoperative infection.

Sufficient vitamin D cuts the risk of surgical complications in half. One study found that half of atrial fibrillation was reduced with enough vitamin D. Vitamin D is especially important for open-heart surgery, thyroid removal, and cancer removal.

Surgery puts significant stress on your adrenal glands. If you’re low in vitamin D, cortisol can spike 4x after surgery, slowing healing and increasing inflammation.

If you’re low in vitamin D, you’re 8 times more likely to have cognitive dysfunction after surgery. Vitamin D can reduce the risk of rejection during an organ transplant and is associated with fewer complications with ventilators after surgery.

If you take vitamin D before surgery, you can expect shorter hospital stays and faster healing rates. If you only take high doses of vitamin D for 3 days before surgery, you don’t need to worry about any toxic effects.
