PCOD Explained: Symptoms, Causes, Treatment & How It Differs From PCOS

Quick Summary

PCOD (Polycystic Ovarian Disease) is a common hormonal condition where the ovaries release too many partially mature or immature eggs, which can build up into small cysts over time. It is triggered mainly by lifestyle and hormonal factors, causes irregular periods, acne, weight gain, and unwanted hair growth, and is usually manageable with diet, exercise, and medication. It is different from PCOS (Polycystic Ovary Syndrome), a deeper metabolic and endocrine disorder that carries a higher long-term risk of diabetes, heart disease, and fertility issues.

What Is PCOD?

PCOD (Polycystic Ovarian Disease) is a condition in which a woman’s ovaries produce an unusually high number of immature or partially matured eggs during her monthly cycle. Instead of being released normally, many of these eggs stay inside the ovary and gradually turn into small fluid-filled sacs, giving the ovary a “polycystic” or multi-cyst appearance on an ultrasound.

This build-up disturbs the normal hormone balance in the body. The ovaries begin producing slightly higher levels of androgens (male hormones), which is what leads to the visible symptoms most women associate with PCOD – irregular periods, acne, and excess hair growth.

How Common Is PCOD?

PCOD is one of the most frequently diagnosed hormonal conditions in women of reproductive age, and it is increasingly being seen in teenagers due to changing diets, sedentary routines, and rising stress levels. It affects women differently – some experience mild, occasional symptoms, while others notice a bigger impact on their periods, skin, and weight.

What Causes PCOD?

There is no single cause of PCOD. It usually develops from a combination of the following factors:

1. Hormonal Imbalance – A disruption in the balance of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) prevents eggs from maturing fully, leading to partial follicle development.

2. Insulin Resistance – When the body’s cells don’t respond well to insulin, the pancreas produces more of it. Higher insulin levels can push the ovaries to produce more androgens.

3. Genetics and Family History – Women with a mother, sister, or close relative who has PCOD or PCOS are statistically more likely to develop it themselves.

4. Lifestyle Factors – Poor diet, lack of physical activity, high stress, irregular sleep, and rapid weight gain are strongly linked to the onset and worsening of PCOD symptoms.

5. Excess Weight – Being overweight doesn’t cause PCOD on its own, but it can intensify hormonal imbalance and make symptoms more noticeable.

What Are the Symptoms of PCOD?

Symptoms vary from woman to woman, but the most commonly reported signs include:

• Irregular or unpredictable periods – cycles that are delayed, skipped, or too frequent
• Acne and oily skin – caused by mildly elevated androgen levels
• Weight gain, especially around the abdomen
• Excess hair growth (hirsutism) on the face, chest, or back
• Hair thinning or hair fall on the scalp
• Mood swings, fatigue, or low energy
• Difficulty conceiving in some cases due to irregular ovulation
• Dark patches of skin, particularly around the neck or underarms

Does PCOD Always Cause Infertility?

No, most women with PCOD can conceive naturally or with mild medical support, since PCOD typically causes irregular – not absent – ovulation, unlike more severe hormonal disorders.

How Is PCOD Diagnosed?

Doctors at MGM Malar typically use a combination of the following to confirm a PCOD diagnosis:

• Detailed symptom and menstrual history review
• Pelvic or transvaginal ultrasound to check for multiple immature follicles in the ovaries
• Blood tests to measure hormone levels (LH, FSH, androgens, insulin, thyroid function)
• BMI and weight assessment to understand lifestyle-linked risk factors

A single symptom or ultrasound finding is not enough – diagnosis usually needs a combination of clinical signs and test results.

PCOD vs PCOS: What Is the Real Difference?

This is the most searched question on this topic, so here is a direct, side-by-side answer.

Point of Comparison	PCOD	PCOS
Full Form	Polycystic Ovarian Disease	Polycystic Ovary Syndrome
Nature of Condition	A common hormonal and ovulatory disorder	A more complex metabolic and endocrine syndrome
Severity	Usually milder	Often more severe, with wider health impact
Root Cause	Mainly lifestyle-linked hormonal imbalance	Deeper insulin resistance and androgen excess affecting the whole body
Ovulation	Irregular, but egg release usually still happens	Ovulation is frequently absent or very infrequent
Fertility Impact	Mild to moderate; most can conceive with support	Higher risk of fertility challenges
Long-Term Health Risk	Lower risk if managed early	Higher risk of type 2 diabetes, heart disease, and metabolic syndrome
Reversibility	Often significantly improves with lifestyle changes	Requires long-term, ongoing management
Treatment Approach	Diet, exercise, weight management, cycle regulation	Medication, hormonal therapy, and closer long-term monitoring

Quick Decision Guide: Which Condition Might You Have?

• If your periods are irregular but you still get them fairly often → more consistent with PCOD
• If your periods are frequently missed for months at a time → more consistent with PCOS
• If you have marked weight gain, high insulin resistance, or strong family history of diabetes → PCOS is more likel
• Either way, only a doctor’s evaluation with ultrasound and blood tests can confirm which condition you have

How Is PCOD Treated?

There is no single “one-size-fits-all” treatment. At MGM Malar, treatment plans are usually built around the symptoms that are bothering the patient most.

Step-by-Step Approach to Managing PCOD

1.Lifestyle correction first – structured diet changes and regular physical activity, since even a 5–10% reduction in body weight can noticeably improve cycle regularity

2.Menstrual cycle regulation – hormonal medication (such as birth control pills) may be prescribed to regularize periods

3.Insulin-sensitising medication – used when insulin resistance is contributing to the imbalance

4.Anti-androgen treatment – for excess hair growth or acne, if required

5.Fertility support – ovulation-inducing medication for women trying to conceive

6.Regular follow-ups – periodic ultrasound and hormone checks to track progress

Living With PCOD: Diet and Lifestyle Tips

• Choose low-glycemic, fibre-rich foods (whole grains, vegetables, legumes) over refined sugar and processed food
• Aim for at least 30 minutes of physical activity, most days of the week
• Prioritise 7-8 hours of sleep to support hormonal balance
• Manage stress through activities like yoga, walking, or meditation
• Avoid crash diets, which can further disturb hormone levels
• Keep regular checkups even after symptoms improve, since PCOD needs ongoing monitoring

Who Should See a Doctor?

You should consider consulting a gynaecologist at MGM Malar if you notice:

• Periods that are missed, delayed, or unusually irregular for more than 2-3 cycles
• Sudden or excessive hair growth on the face or body
• Persistent acne that doesn’t respond to regular skincare
• Unexplained weight gain that is hard to manage
• Difficulty conceiving after several months of trying

Early evaluation makes a real difference – the earlier PCOD is identified, the easier it is to manage before it affects long-term health or fertility.
