If you are gearing up for an immigration medical exam, especially here in Houston, you might be wondering: “How do I prepare for this? Do I need to fast? Should I avoid certain foods or activities before the physical?” At Apex Urgent Care Clinic, we frequently receive these questions from patients visiting for immigration physicals.
While immigration physicals might seem like a straightforward check-up, there is more to it than just showing up and hoping for the best. Your body’s state during the exam, hydration, blood pressure, and lab results can impact how smoothly the process goes. That is why we have put together this practical timeline to help you prepare physically, one week ahead, up to the day of your exam.
One Week Before: Lay the Groundwork

You might not think seven days out matters, but it does. Start by asking yourself: Do I have all my medical records and vaccine history ready? Gather these now so you are not scrambling later.
Physically, this is a good time to start drinking more water daily. Hydration helps your body regulate blood pressure and kidney function. You don’t need to overdo it—aim for around eight glasses of water daily.
Also, if you smoke or drink alcohol regularly, cutting back now gives your body a better baseline. Things like white blood cell count and liver enzymes can be affected by alcohol, so giving your body a little detox time helps your immigration physical results.
Three Days Before: Fine-Tune Your Routine
Now it is time to clean things up. Are you wondering: “Can I eat my usual diet before my immigration physical?” The answer is yes, but avoid heavy, fatty foods or salty snacks.
Foods high in sodium increase blood pressure temporarily. For example, skip fast food or instant noodles these days. Focus on balanced meals with fruits, vegetables, lean protein, and whole grains.
Do not forget about exercise. While the regular movement is okay, avoid starting new high-intensity workouts during this time. You want your body to be calm and steady.
Two Days Before: Light and Easy Wins the Race
Two days out, check in with yourself: “How am I feeling?” This is not the time to push yourself physically. Avoid strenuous activity, heavy lifting, or anything that leaves you sore or stressed.
Keep meals light and healthy. Continue hydrating, but avoid taking a lot of water before bedtime to avoid waking up in the middle of the night.
If you feel under the weather—cough, fever, or anything-consider calling our Houston doctor at Apex Urgent Care Clinic.
It is better to reschedule than to show up sick.
The Day Before: Rest
You made it! Now, make sure you get a good night’s sleep, aim for at least 7–8 hours. Your body’s resting state affects everything from blood pressure to blood sugar.
Here is a common question we hear: “Should I fast before an immigration medical exam?” The answer depends on the clinic, but for immigration physicals, fasting is not required. At Apex Urgent Care Clinic, our Houston doctor advises you to eat a light, healthy breakfast unless instructed otherwise.
Avoid alcohol and caffeine, as they can affect your hydration and heart rate. This is true if you tend to get nervous at medical appointments—white coat syndrome is real!
The Day Of: Keep It Calm, Keep It Simple
On exam day, wake up early, drink a glass of water, and eat a light meal—think oatmeal, toast, or yogurt. Dress in comfortable clothing and bring all the paperwork, including your vaccination records and ID.
If you feel faint during blood draws, let the medical team know. At Apex Urgent Care Clinic, we often help patients through this by allowing them to lie down while drawing blood.
Finally, take a few deep breaths. You have prepared well, and your immigration physical is just one more step in your journey. Our Houston doctor is here to guide you through it with care and professionalism.
