What Are Major Risk Factors for Anesthesia? A CRNA Explains

If you’re lying awake at night wondering whether your health condition, your medications, or something in your medical history makes anesthesia too risky, you’re not alone. As a CRNA with 20 years of experience, I hear this question almost every week. Just recently, a reader reached out to me. He had a well-controlled chronic condition and had concerns about the effects anesthesia may have on his body, largely due to this health condition. He had already delayed his needed surgery once because the fear of anesthesia felt overwhelming. When he shared the details, I was able to reassure him gently: “Your condition is something we manage safely every single day. It’s not considered a major risk factor for anesthesia.”
That conversation is exactly why I created this website. Thousands of people just like him are postponing important care—not because of clinical anxiety, but because they’re smart, health-aware individuals who simply can’t find clear, trustworthy answers from a real provider. Today I want to arm you with the same knowledge and courage I gave him. Let’s talk openly about what truly counts as a major risk factor for anesthesia—and, more importantly, what doesn’t—so you can move forward with confidence instead of fear.
What Actually Makes Anesthesia Riskier?
Anesthesia is remarkably safe for the vast majority of people, but certain situations do raise the level of attention we give. These are some of the major risk factors that anesthesia providers watch most closely:
Severe, uncontrolled heart disease (such as recent heart attack, unstable angina, or severe heart failure)
Serious lung conditions that are not well managed (such as advanced COPD or poorly controlled asthma requiring frequent hospitalizations)
Emergency surgery in a critically ill or unstable patient
Extremely high body mass index combined with untreated sleep apnea
End-stage renal disease requiring dialysis
Certain very rare genetic conditions that affect how the body handles anesthesia medications (like malignant hyperthermia-familial history)
Very advanced age (typically over 85) with multiple serious medical problems
These are the situations where we may bring in extra monitoring, extra team members, adjust the surgical plan, or have a patient see a specialist pre-opertively.
Even then, the vast majority of patients still do very well.

What Most People Worry About (But Usually Isn’t a Major Risk)
Here’s the good news—and the part I wish every patient heard before surgery: most of the conditions people lose sleep over are not major risk factors when they’re well controlled.
Controlled high blood pressure, diabetes, thyroid disease, or neurological disorder
Mild to moderate asthma or seasonal allergies
Taking common medications like blood pressure pills, statins, antidepressants, or medication that helps you manage your condition
Being overweight but otherwise healthy
If your condition is stable and your doctors are comfortable proceeding, anesthesia teams have safely cared for thousands of patients like you. And if you are supposed to hold a medication, your surgeon or anesthesia team should reach out to you prior to your planned procedure to let you know when to stop taking it. Just be very honest with your surgeon and anesthesia team about your health conditions and the medications you are taking.
Why Knowing Major Risk Factors for Anesthesia Matters More Than You Think
When people delay needed surgery out of fear of anesthesia, they often end up facing bigger problems later. Pain gets worse, conditions progress, and quality of life suffers. That’s why I wrote every article on this site: to give you the straight talk you deserve from someone who’s actually at the head of the bed every day.
You don’t have to carry this worry alone.

If you have a health condition that’s making you pause before surgery, I want you to do three things:
Write down your specific concerns (the exact condition, the medication, the fears).
Bring that list to your next surgery consultation, primary care visit, or anesthesia consult and say, “I read an article by a CRNA, and I have some questions.”
Reach out here if you still need reassurance. I read every message and respond personally. You are not bothering anyone—you’re doing exactly what this site was built for.
Final Thoughts
Major risk factors for anesthesia are definitely real, but they are also relatively uncommon and almost always manageable when your care team knows about them. The vast majority of what people worry about—especially well-controlled chronic conditions—is simply not on that high-risk list.
You are health-aware, not fearful. That awareness is a strength. Use it. Talk to your anesthesia provider, ask the questions, get the answers, and give yourself permission to move forward with the care you need.
You’ve already taken the first brave step by reading this far. The next step—scheduling or confirming your surgery—will feel a lot lighter once you know you’re in experienced, caring hands. Remember, prepared patients have better outcomes.
If you’re still carrying that reader’s same worry today, please know this: you are not alone, your condition is probably far less risky than it feels right now, and there are thousands of us cheering you on.
