Your Blood Work Is Talking. Are You Listening?

Last month, a man came into our Narcoossee Road office. Fifty-one years old, felt great. His wife had been after him for two years to schedule a physical. He finally came in — no complaints, just wanted to check the box. His blood work came back with an A1C of 6.7. That's diabetes. He had zero idea. No symptoms, no fatigue, nothing. He walked out with a plan instead of walking into a crisis two years later when his kidneys or eyes would have started paying the price.

That happens constantly. And it's the clearest argument I have for why routine blood work matters, even when you feel fine — especially when you feel fine.

Here's my honest position: waiting until you feel sick to get labs done is a losing strategy. Diabetes, high cholesterol, thyroid disease, early kidney damage — these conditions don't usually send warning shots. They're quiet. By the time you're exhausted all the time, or your feet are going numb, or you notice your heart doing something strange, we've already lost years of runway. Blood work gives us a map before the road turns bad.

In Central Florida specifically, I see certain patterns over and over. Type 2 diabetes shows up at disproportionate rates in Latino and Black communities — and our community here in Orlando reflects that. The food culture doesn't help. I'm not telling patients to stop eating arroz con frijoles or chicharrones. But portions, frequency, and what else is on the plate — those details compound over time. And Florida's summers push people inside, into the AC, away from movement. That affects blood sugar, blood pressure, and kidney health. We see it in the numbers every day.

A standard metabolic panel tells us how your liver and kidneys are doing. A CBC flags anemia — which I find a lot in women who don't know they're running low on iron. A lipid panel catches cholesterol problems before they've had a chance to scar your arteries. If you've been tired for months and gaining weight without explanation, add a TSH to check your thyroid. If your energy is just off — even here in Florida with all this sunshine — get your vitamin D checked. Floridians are deficient more often than you'd expect because most of us are inside in air conditioning between 9 AM and 6 PM.

One thing I say to patients regularly: cholesterol does not hurt. It doesn't give you a headache or make your chest tight, not at first. It just builds. Then one day it causes a heart attack in a 48-year-old who thought he was perfectly healthy. I would rather catch a bad lipid panel at 38 and have a conversation about it than meet that same person in the emergency room at 50.

Here's what you can do this week. If you haven't had blood work in the past year, call and get it scheduled. Most insurance plans, including many Florida Medicaid plans, cover annual lab work at no cost to you. If cost is a concern, ask us — we find a way to work with patients. For a full lipid and glucose picture, a 9-to-10 hour overnight fast the night before is enough. Drink water, come in the morning, it takes ten minutes.

When to Call Us Sooner Than Your Next Annual Visit

Sudden fatigue that doesn't get better after real rest. Urinating much more than usual, especially at night. A thirst that won't quit no matter how much you drink. Swelling in your feet or ankles. Heart palpitations that come and go. Unexplained weight gain or loss of ten or more pounds without changing how you eat. A family history of heart disease, diabetes, or kidney disease that you've never been screened for. These are not wait-and-see situations. Call.

I hear from patients who put off labs because they're scared of what might come back. That makes sense. But I'd much rather sit down with you over a number on paper — something concrete we can work with — than have a harder conversation later when our options have shrunk. Most of the time, when we catch things early, lifestyle changes genuinely move the needle. Sometimes medication helps. But none of that is possible if we don't know where you are right now.

If you're overdue for blood work or haven't had a physical in a while, come see us. We have two locations in Orlando and we take same-day appointments — you won't wait weeks to get in. Dr. Arevalo speaks English and Spanish and sees patients of all ages. We go through your results with you in the room, not just hand you a printout and send you out the door.

Your annual labs are one of the most useful things you'll do for your health this year. Schedule it like you would anything else that matters.
