5 DEADLY Signs Your Immune System Is Attacking You (Autoimmune Disease)

Added: 2026-05-31

[00:00:00]Your doctor told you everything looks normal.  But you are exhausted. Your joints ache for no reason. Your hair is falling out. Your brain  is foggy. And your hands — they change colors in the cold. What if I told you these are  signs of your immune system quietly attacking your own body for months—or even years? I'm Dr. Diana Girnita, a board-certified rheumatologist, and in this video, I  will teach you 5 specific signs that make me think about autoimmune diseases, even  before I order any blood tests to confirm it.

[00:00:38]Stay with me — because this video could  save you many years of suffering and avoid seeing 10 specialists before  you are sent to a rheumatologist.

[00:00:48]SIGN #1 — Fatigue That Sleep Doesn't Fix Let's start with the most dismissed symptom in all of medicine. Fatigue. Yes, not  regular tiredness. Not that kind of tiredness that a good night's sleep fixes. I mean, waking up after eight hours and feeling like you never slept. Hitting 2 pm and feeling like you physically cannot go on. Feeling exhausted in a  way that your workload, your sleep, and your stress level cannot explain. This is inflammatory fatigue.

[00:01:33]It is driven by cytokines — inflammatory proteins  your immune system releases when it is activated.

[00:01:42]They signal your brain to conserve energy because  your body thinks it is fighting something serious.

[00:01:52]Even when there is no infection. Even  when every lab comes back normal.

[00:01:59]Every week in my clinic, I hear the same thing:  "I used to be the person who did everything. Now I can barely get through the day." And  their doctors told them they were fine.

[00:02:14]Here is what makes this fatigue clinically  meaningful: it is persistent — weeks or months, not days. It comes with brain fog —  trouble concentrating, finding words, thinking clearly. And it almost always shows up  alongside at least one or two of the other signs on this list that we will discuss today. Now, sign #2 is happening in your joints… and most people are living with it for years without realizing what it means..." SIGN #2 — Morning Stiffness That Lasts Over an Hour Quick question.

[00:02:56]When do your joints hurt most — in  the morning, or later in the day?

[00:03:01]That timing is one of the most powerful diagnostic  clues in rheumatology. It separates inflammatory arthritis from regular wear and tear  almost immediately. Let me explain: With osteoarthritis — pain gets worse through  the day with repetitive use. It is Better in the morning after resting through the night. With inflammatory arthritis —like rheumatoid arthritis, psoriatic arthritis — it is  the complete opposite. It is Worst in the morning. Lasts over an hour. And actually  improves as you move and the joints warm up.

[00:03:46]That is why I ask every patient: do you need  a hot shower before your hands work properly?

[00:03:54]Do your rings feel tight when you first wake up? Does it take over an hour before you feel like yourself? Because….That is not aging.

[00:04:05]That is inflammation. In rheumatoid arthritis, the base knuckles and middle finger joints  are affected — on both hands, at the same time. That symmetric pattern is a red flag. In psoriatic arthritis, one finger can swell up like a sausage overnight — what we call dactylitis  — which is one of the most specific signs I know.

[00:04:34]Joint damage from inflammatory arthritis  is not reversible. But if we catch it early — we can stop it from happening at all. "This was Sign number two. Now sign number three shows up somewhere most patients never  think to look — and it is the most visible, most underrecognized clue in  all of autoimmune medicine..." SIGN #3 — Skin and Hair  Changes You Keep Dismissing Your skin is the largest organ in your body. And  it is often the first place your immune system leaves a visible clue. A butterfly-shaped rash  across the cheeks and nose — worse in sunlight — is one of the most recognized signs of lupus. but….Not everyone with lupus develops it.

[00:05:24]But when I see it, it immediately  redirects my entire evaluation.

[00:05:30]Skin that feels tight, puffy, or harder to move  — especially on the fingers, hands, or around the mouth — these can signal scleroderma, where  the immune system attacks connective tissue.

[00:05:44]Then, Psoriasis — have you seen people with  red, scaly patches on the elbows, knees, scalp?

[00:05:53]This affects 3% of the population.  And 25-30% of those people will eventually develop psoriatic arthritis, a very  commonly misdiagnosed form of arthritis! So, If you have psoriasis and joint pain, you need  a rheumatologist — not just a dermatologist.

[00:06:17]Let’s talk about a sensitive topic! Hair loss.

[00:06:21]Diffuse shedding all over the scalp — not  just in one spot — is a common complaint in lupus and autoimmune thyroid disease. It  gets dismissed as stress almost every time.

[00:06:34]Sometimes it is stress. But alongside fatigue  and joint pain? That is your immune system.

[00:06:44]Let’s move on to the next sign! The next  one is the one most people blame on aging, screen time, or allergies — but it is  actually one of the most specific clues pointing to a disease that affects 4 million  Americans and is almost never caught early..." SIGN #4 — Dry Eyes and Dry  Mouth That Nothing Fixes How long have you been using eye drops? Do you wake up at night needing water?

[00:07:14]Do you sleep with a glass next  to your bed every single night?

[00:07:18]I ask these questions to all my  patients that come to be evaluated. Why?

[00:07:24]Because dry eyes and dry mouth — when they  are persistent, when they do not respond to over-the-counter remedies, and when they appear  together — are the hallmark of another autoimmune disease called Sjögren's disease. Sjögren's is the  second most common autoimmune rheumatic disease after RA… many times diagnosed late,  misdiagnosed or completely dismissed.

[00:07:56]However, It affects 4 million Americans. And the average time from first symptom to diagnosis is nearly three years — because  patients see an eye doctor for dry eyes, a dentist for dry mouth, a gynecologist for  vaginal dryness — and nobody connects them.

[00:08:20]They are the same disease. Beyond dryness, Sjögren's causes significant fatigue, joint pain, brain fog —  and in some patients, it attacks the lungs, kidneys, and nervous system. The antibodies to look for are anti-SSA and anti-SSB. But up to 25% of Sjögren's patients are antibody-negative, which is exactly why you  need a rheumatologist, not just a blood test.

[00:08:51]Dry eyes, dry mouth, plus fatigue,  plus joint pain, is not aging.

[00:08:57]It is a pattern. And it deserves to be evaluated. "Let’s move on to the last sign…..The fifth sign is the one patients find strangest the first  time it happens — and the most alarming.

[00:09:12]But it is actually one of the most specific  early warnings I know of in rheumatology..." SIGN #5 — Raynaud's: When  Your Fingers Change Color Has anyone ever looked at your hands and asked  "are you okay?" because your fingers had turned white — or blue? That is Raynaud's phenomenon. And  it is one of the most specific early warning signs of connective tissue autoimmune disease. Here is what happens.

[00:09:45]Cold temperatures or emotional stress  cause the small blood vessels in your fingers to over-constrict. Blood flow  cuts off — the finger turns white.

[00:10:00]Blood pools without flowing — it turns blue. When flow returns — it flushes red. Often painful or tingly.

[00:10:08]Raynaud's on its own — called primary  Raynaud's — is usually benign.

[00:10:16]But Raynaud's alongside fatigue, joint  pain, dry eyes, or skin changes is called secondary Raynaud's. And that can be an  early sign of RA, lupus, scleroderma, Sjögren's, or mixed connective tissue disease  until a rheumatologist proves otherwise.

[00:10:36]Especially in scleroderma, Raynaud's phenomenon  often appears years before any other symptoms.

[00:10:43]Which means if your fingers are changing  color — and you have even one other sign from this list — that is not something  to dismiss. That is something to act on.

[00:10:56]THE PATTERN — Why Combination Is Everything Here is the most important thing I want you to take from this video. None of these five signs alone makes a diagnosis.

[00:11:08]Fatigue has a hundred explanations.  So does joint pain. So do dry eyes.

[00:11:14]But when two, three, or four of them appear  together — in a woman between 30 and 65 — with no other clear cause — that is a pattern. And  that pattern is what takes a patient from years of being dismissed to finally getting an answer. Autoimmune diseases cause damage over time.

[00:11:38]Joints erode. Organs get attacked. Glands  stop functioning. The earlier the diagnosis, the better the chance of protecting the  function you have today. The window is real.

[00:11:52]And recognizing these signs is how you find it. If you are recognizing two, three, or more of these signs in yourself, do not wait for  your primary care doctor to connect the dots.

[00:12:06]At Rheumatologist OnCall, we see patients  across 20 states via telehealth — in days, not months. No referrals. No waiting rooms.  A board-certified rheumatologist who will actually look at the whole picture. Now — knowing the signs is only step one. If you stop here, you will know what to watch  for but not what tests confirm it, what treatment options exist, or what you can do today while  you wait for answers. Watch this video to learn more about the top tests that I use to  diagnose people with autoimmune diseases.
