You've spent three hours in a sterile virtual clinic. Your Sim is stressed. The patient is literally glowing orange. You click through every single examination—check ears, take temperature, scan on the X-ray machine—and you’re still staring at three different options for the Sims 4 medical diagnosis. It’s frustrating. Honestly, the Get to Work expansion pack doesn't always play fair, and if you're trying to hit that Top Surgeon promotion, one wrong guess can tank your job performance for the entire day.
Most players think the game is broken when the "guaranteed" diagnosis doesn't pop up. It’s not. Well, usually it’s not. The system is actually a logic puzzle disguised as a career grind. You have to look at the physical symptoms on the Sim's body, not just the data in the interaction menu.
The Visual Clues Most Players Miss
Stop looking at the icons. Seriously. The user interface in the Doctor career is kooky because it gives you "weak" or "compelling" evidence, but sometimes that evidence overlaps between three different illnesses. To get a perfect Sims 4 medical diagnosis, you have to use your actual eyes. Zoom in. Look at the patient's skin.
If you see orange or tiger-like stripes on their arms and face, you aren't looking at a simple cold. That's Gas and Giggles. If they have swirls or "spiral" patterns on their skin, you're likely dealing with Dizzy Wheels. The game uses these visual overlays because the diagnostic tests sometimes fail to narrow it down to a single result. It’s a design choice that mimics real-world medical ambiguity, though with a lot more cartoonish spots.
It's All in the Animation
Sometimes the skin is clear. That’s when it gets tricky. You have to watch the "idle" animations of the patient while they sit on the exam table. Do they keep swatting at the air like there are invisible bugs? That’s a massive giveaway for Starry Eyes, even if your X-ray came back inconclusive. If they are constantly rubbing their stomach or looking like they’re about to vomit, you’re leaning toward Triple Threat or Bloated Head.
Don't just spam the "Perform Tests" button.
Wait.
Watch the patient for ten seconds. The animations repeat on a loop. If you see them scratching themselves constantly, it’s a skin-related ailment like Itchy Plumbob or Llama Flu. The physical acting of the Sims is often more reliable than the "Results" log in the career panel.
Decoding the Sims 4 Medical Diagnosis List
The list of illnesses in The Sims 4: Get to Work is fixed. It doesn't change, and there are no "new" diseases added in patches, which makes it easier once you memorize the patterns. But even a veteran player gets tripped up by the overlap between Llama Flu and Triple Threat.
Let’s break down the actual logic the game uses.
The "Easy" Identifiers

- Burning Belly: This one is a bit of a lie. The Sim will occasionally complain about abdominal pain, but the "Surgery" requirement is the dead giveaway. If the diagnostic tests suggest surgery, it's either this or a minor case of Triple Threat.
- Gas and Giggles: You'll see stripes. They’ll laugh for no reason. It’s weird. They might even pass gas. It’s one of the few diagnoses that is almost impossible to miss.
- Starry Eyes: Look for the literal stars circling the Sim's head. If you see the stars, stop testing. You're done. Just prescribe the medication.
The "Frustrating" Overlaps
Llama Flu and Triple Threat are the banes of a Sim doctor's existence. Both involve sneezing and coughing. However, Triple Threat usually comes with dizziness (the swirls on the skin) or the need for surgery. Llama Flu is more about the fever. If you see the thermometer icon show a high temp but the skin is clear of stripes or swirls, it’s almost always Llama Flu.
Why Your Tests Come Back Inconclusive
You’ve done the Treadmill test. You’ve done the X-ray. You’ve swabbed their mouth. And the game still says "Inconclusive."
This happens when your Sim’s Logic skill is too low or your Medical level isn't high enough yet. As you level up from an Orderly to a Nurse and eventually a Surgeon, your ability to "guarantee" a Sims 4 medical diagnosis increases. At lower levels, the game intentionally keeps things vague to force you to guess.
Pro Tip: If you're stuck, use the "Refer for X-ray" or "Refer for Treadmill Test" options. These are higher-tier actions that provide much stronger "Compelling Evidence" than just checking their ears with a flashlight. If those still don't work, look at the patient’s moodlets if they are in your household, or simply look for the visual VFX.
The Surgery Table Trap
Newer players often think the Surgery Table is just for the "Surgery" career level. Nope. It’s a diagnostic tool too. If you’ve done everything else and the diagnosis is still a toss-up between two options, send them to the table. If the game allows you to "Perform Surgery," then the illness is officially one that requires it. If the option is greyed out, you know you’re looking at something that needs a shot or a pill.
Dealing with Ghost Patients and Glitches
Let's be real. The Sims 4 is buggy. Sometimes you'll get a patient who sits on the exam table and then... nothing. You can't interact with them. Or worse, you give the correct Sims 4 medical diagnosis, treat them, and the game tells you that you were wrong.
If a patient is stuck, try resetting them using the resetsim [Firstname] [Lastname] cheat. It won't hurt your career progress. Also, keep an eye on the hospital staff. Sometimes the "Orderly" Sims will take up the exam tables by just standing there, preventing you from bringing in new patients. If the hospital is full of people but no one is assigned to a bed, go to the front desk and "Assign Patient to Bed" manually. It jumpstarts the AI logic.
Speedrunning the Doctor Career
You want the promotion. You don't care about the patients. I get it. To fly through the ranks, you need to maximize your "Successful Diagnoses" per day.
- Morning Prep: Don't talk to coworkers. Go straight to a patient.
- The Triple Check: Check Ears, Check Eyes, Take Temperature. These are the fastest animations.
- The Visual Look: While your Sim is doing the "Check Eyes" animation, look for spots, stripes, or stars on the patient.
- The Guess: If you see stars, immediately diagnose Starry Eyes. Don't wait for more tests.
- The Treatment: Deliver the medicine and move to the next bed.
Efficiency is king. A "Correct" diagnosis based on a 50/50 guess is worth just as much career XP as a "Guaranteed" diagnosis that took four hours of testing. If you've narrowed it down to two choices and the shift is ending, just pick one. The odds are in your favor.
The Mystery of the "Sweaty" Sim
If a Sim looks like they are constantly shimmering or "sweaty," they likely have a fever. In the Sims world, this is almost always Llama Flu. However, if they have spots and are sweaty, you’re looking at Itchy Plumbob. It’s a subtle distinction. Most people confuse the "sweat" VFX with the "dizzy" VFX. Sweat is vertical lines; dizziness is spirals.
Actionable Steps for Your Next Shift
To stop failing your medical career goals, change how you play the workday.
First, upgrade your Logic skill at home. High logic reduces the "Inconclusive" result rate significantly. A Sim with Level 10 Logic will almost never see a "Weak Evidence" notification after an X-ray.
Second, memorize the "Surgery" illnesses. Burning Belly, Triple Threat (sometimes), and any "Critical" emergency that comes in via the ambulance will require the surgery table. If the patient is collapsed on the floor when they arrive, don't bother with the ear light. Get them to the table immediately.
Finally, ignore the social needs. The Doctor career is high-pressure. If you spend time gossiping with the Head Nurse, you’ll only diagnose two patients a day. Aim for five. Even if you get one wrong, the volume of correct diagnoses will carry your performance meter to the gold zone.
Get in there, look for the stripes, and stop overthinking the thermometer. The game is simpler than it looks, provided you're actually watching the Sims and not just the UI.
