TL;DR – Key Takeaways
- PCOD and PCOS are the SAME condition. No difference. Just two names for one disorder.
- PCOD Fullform = Polycystic Ovary Disease (India, some countries)
- PCOS Fullform = Polycystic Ovary Syndrome (International standard, USA, UK, most of world)
- Why different names? Terminology evolved differently in different countries. Nothing medical.
- Symptoms: Identical. Diagnosis: Identical. Treatment: Identical.
- Use whichever name you prefer. Both are medically correct and accepted by doctors worldwide.

The Short Answer
Yes, PCOD and PCOS are the same thing.
If your doctor told you that you have PCOD, you have what other doctors call PCOS.
There’s no separate disease called PCOD that’s different from PCOS.
It’s literally the same condition. Just two different names.
The “D” vs “S” comes down to terminology history, not medical difference.
Why Two Different Names?
Historical Terminology Evolution
When the condition was first identified in 1935, it was called “Stein-Leventhal Syndrome” (named after the doctors who described it).
Later, doctors in different countries settled on different names:
In India and Some Other Countries:
- Called it “PCOD” = Polycystic Ovary Disease
In the USA, UK, and Internationally:
- Called it “PCOS” = Polycystic Ovary Syndrome
Why “Disease” vs “Syndrome”?
This is the only real difference:
“Disease” (PCOD):
- Implies a specific, clearly defined condition
- Used more in older medical terminology
- Still used in India and some countries
“Syndrome” (PCOS):
- Implies a collection of symptoms that occur together
- More modern medical terminology
- Currently the international standard
Which is “Correct”?
Both are correct. They’re just different naming conventions.
The World Health Organization and international medical bodies recognize PCOS as the standard term.
But PCOD is equally valid and used by millions of doctors globally.
It’s like calling a tissue “Kleenex” or “tissue.” Same product, different names.
The Medical Definition
PCOS/PCOD Definition (Same for Both)
A hormonal disorder affecting women of reproductive age, characterized by:
- Irregular ovulation or no ovulation
- Causes irregular or absent periods
- Excess androgen (male hormone) production
- Causes hair loss, acne, unwanted hair growth
- Polycystic appearance on ovarian ultrasound
- Multiple small follicles on ovaries (though not always present)
Rotterdam Diagnostic Criteria
For diagnosis, you need 2 of these 3 features:
- Irregular periods OR evidence of anovulation
- Clinical or biochemical signs of hyperandrogenism (high male hormones)
- Polycystic ovaries on ultrasound
This is the same whether you call it PCOD or PCOS. No difference.
Symptoms Are Identical
Whether You Call It PCOD or PCOS, You Experience:
Reproductive Symptoms:
- Irregular periods
- Missed periods
- Heavy periods
- Difficulty getting pregnant
Hormonal Symptoms:
- Acne (hormonal, persistent)
- Hair loss (scalp thinning)
- Unwanted facial/body hair
- Male pattern baldness
Metabolic Symptoms:
- Weight gain or difficulty losing weight
- Insulin resistance
- Fatigue
- Darkened skin patches (acanthosis nigricans)
Emotional Symptoms:
- Mood swings
- Anxiety
- Depression
- Low mood around menstruation
All women with PCOD experience these. All women with PCOS experience these.
Because they’re the same condition.
Diagnosis Is Identical
Whether Called PCOD or PCOS
You get the same tests:
- Blood tests (testosterone, LH, FSH, glucose, insulin)
- Pelvic ultrasound
- Assessment against Rotterdam Criteria
The diagnosis process is identical. No difference.
Treatment Is Identical
Whether You Have PCOD or PCOS, Treatment Options Are:
Lifestyle Management (Same for Both):
- Diet modifications
- Regular exercise
- Weight management (if needed)
- Stress management
- Sleep optimization
Medical Management (Same for Both):
- Birth control pills (regulate cycles)
- Metformin (improve insulin sensitivity)
- Anti-androgen medications (reduce male hormones)
- GLP-1 agonists (emerging treatment)
Natural/Ayurvedic (Same for Both):
- Herbal supplements
- Dietary approaches
- Lifestyle modifications
All treatment is identical whether you have PCOD or PCOS.
Because they’re the same condition being treated the same way.
Why Does Terminology Matter?
It Matters More Than You’d Think
While Researching Online:
- Searching “PCOD” returns different results than “PCOS”
- Some resources use one term, some use the other
- This can make research confusing
During Finding Communities:
- PCOS communities online are huge (mostly international)
- PCOD communities exist (India-focused)
- Both have the same information, slightly different cultural context
When Communicating with Doctors:
- Your Indian doctor might call it PCOD
- An international doctor might call it PCOS
- They’re talking about the same thing but using different terms
While Reading Studies:
- Medical research uses PCOS almost exclusively now
- Older Indian literature uses PCOD
- Just know they’re the same thing
The Real Impact
If you’re confused about whether PCOD and PCOS are different, you might:
- Worry you have a different disease than your friend
- Feel isolated because you can’t find relevant information
- Get confused by terminology when researching
Clarity: You have the same condition, just different names.
How to Use Both Terms
Best Practice: Use PCOS
When discussing your condition internationally or with new doctors, use PCOS. It’s the modern, accepted standard.
Say: “I have PCOS” (polycystic ovary syndrome)
It’s Okay to Use PCOD
Especially if:
- Your Indian doctor uses this term
- You’re talking to other Indian women
- You’re reading Indian medical literature
Say: “I have PCOD” (polycystic ovary disease)
Use Both if You Want Clarity
When explaining to someone unfamiliar, say:
“I have PCOD (sometimes called PCOS). It’s a hormonal disorder affecting my ovaries.”
This makes it clear both terms refer to the same thing.
What NOT to Do
Don’t say:
- “PCOD is different from PCOS” (wrong)
- “PCOD is worse than PCOS” (not true, same condition)
- “PCOS only happens in Western countries” (false, it’s global)
- “PCOD is unique to India” (false, it’s the same worldwide)

FAQ
Q: Which name should I use?
A: Both are correct. Use PCOS internationally (it’s the modern standard). Use PCOD if you prefer or when speaking to Indian doctors.
Q: Is one worse than the other?
A: No. PCOD and PCOS have identical prognosis, symptoms, and treatment. Naming doesn’t affect severity.
Q: Why does my doctor call it different names?
A: Because they learned different terminology. In India, PCOD is common. Internationally, PCOS is standard. They’re the same condition.
Q: Should I get a second opinion if one doctor calls it PCOD and another calls it PCOS?
A: Only if you want confirmation of diagnosis, not because of terminology. The names refer to the same thing.
Q: Which term will I see more online?
A: PCOS. International resources, studies, and communities predominantly use PCOS. But PCOD appears in Indian resources.
Q: If I have PCOD, do I need different treatment than PCOS?
A: No. Treatment is identical whether you call it PCOD or PCOS.
Q: Why is PCOS becoming the standard?
A: Because it’s more descriptive (syndrome = collection of symptoms) and it’s the term adopted by international medical organizations.
Q: Is there any reason to prefer one term over the other medically?
A: No medical reason. Pure terminology preference. Both are accepted and understood by medical professionals.
Q: What if I’m confused about my diagnosis?
A: Ask your doctor to explain. Whether they call it PCOD or PCOS, ask them to explain the symptoms you have and why it fits the Rotterdam Criteria.
Q: Can I have PCOD instead of PCOS, or only one?
A: It’s not “instead of.” You have one condition with two names. You don’t choose between them. Doctors just call it by different names depending on their region/training.
The Bottom Line
PCOD = PCOS. They’re the same thing.
Stop worrying about which term is “right.” Both are right.
Whether you call it polycystic ovary disease (PCOD) or polycystic ovary syndrome (PCOS), you have:
- The same symptoms
- The same diagnosis
- The same treatment
- The same prognosis
The only difference is the word. The medicine is identical.
So stop the terminology confusion and focus on what matters: managing your condition and feeling better.
Eat Healthily. Stay Healthy.
