PCOD vs PCOS: Symptoms, Tests, Diet and Treatment

PCOD vs. PCOS: what's the difference?

In everyday conversation, especially in India, "PCOD" and "PCOS" are often used interchangeably, but they're not clinically identical. PCOS (polycystic ovary syndrome) is a hormonal and metabolic condition where the ovaries produce higher-than-typical levels of androgens, which can prevent regular ovulation. PCOD (polycystic ovarian disease) is a broader, less strictly defined term for ovaries releasing multiple immature or partially mature eggs, which can eventually turn into cysts. PCOS is generally considered the more significant hormonal condition of the two. A gynecologist or endocrinologist can tell you which term applies to your specific case, and an online gynecologist consultation is often enough for that first conversation.

Symptoms of PCOD and PCOS

Symptoms vary widely from person to person, and you don't need to have all of them to have PCOD/PCOS. Common signs include:

• Irregular, infrequent, or absent periods
• Excess hair growth on the face, chest, or back (hirsutism)
• Persistent acne or oily skin
• Thinning hair or hair loss on the scalp
• Weight gain, especially around the abdomen, or difficulty losing weight
• Skin darkening around the neck or skin folds (acanthosis nigricans)
• Difficulty conceiving

What causes PCOD/PCOS?

The exact cause isn't fully understood, but three factors are consistently linked to it: insulin resistance (which raises androgen production), higher-than-typical androgen levels, and genetics — PCOS often runs in families. Excess weight can worsen insulin resistance and symptoms, but PCOS also occurs in people who are not overweight.

How common is PCOS in India?

PCOS is one of the most common endocrine conditions affecting women of reproductive age. Indian studies report a wide prevalence range — roughly 4% to 22% depending on the region studied, the age group, and which diagnostic criteria were applied. That spread isn't a contradiction: the Rotterdam criteria identify more women than the older, narrower definitions, and urban and clinic-based samples tend to report higher rates than rural community samples. What the numbers consistently show is that PCOS is common, frequently under-diagnosed, and often identified years after symptoms first appear.

Delayed diagnosis matters because the metabolic side of PCOS — insulin resistance in particular — is easier to manage early. Many women in India first seek help for irregular periods, unwanted hair growth or difficulty conceiving, and only then learn those symptoms share a single underlying explanation.

How is PCOD/PCOS diagnosed?

There's no single test for PCOS. Doctors typically look at a combination of factors: your period history and symptoms, a pelvic ultrasound to check the ovaries, and blood tests to measure hormone levels and rule out thyroid or other conditions. Many clinicians use the Rotterdam criteria, which requires at least two of three features: irregular ovulation, signs of excess androgens, and polycystic ovaries on ultrasound.

Tests a doctor may order include LH and FSH, total and free testosterone, DHEAS, prolactin, TSH (to rule out thyroid disorders, which can mimic PCOS), fasting glucose and fasting insulin or HbA1c to assess insulin resistance, a lipid profile, and sometimes AMH. A pelvic or transvaginal ultrasound looks at ovarian appearance and follicle count. Importantly, polycystic-appearing ovaries on a scan alone do not equal PCOS — many women have them without the syndrome, which is exactly why the diagnosis requires more than one criterion.

Bring cycle dates to the appointment if you have them — tracking your cycle for a few months makes this straightforward. A record of how long your cycles actually run, across several months, is often the single most useful piece of information a clinician can have, and it's the thing most people can't recall accurately from memory.

Diet and lifestyle: what the evidence supports

Lifestyle change is the first-line management approach for PCOS in most clinical guidelines, primarily because it targets insulin resistance, which drives much of the hormonal picture. A few things are reasonably well supported:

• Overall dietary pattern matters more than any single food. No food cures or causes PCOS. Diets that moderate refined carbohydrates and added sugar, and emphasise fibre, protein and whole grains, tend to help insulin sensitivity.
• Regular movement helps independently of weight loss. Both aerobic exercise and resistance training improve insulin sensitivity, and the benefit shows up even when body weight doesn't change much.
• Modest weight reduction can be disproportionately useful. Where weight loss is clinically appropriate, a 5–10% reduction is often enough to improve cycle regularity and ovulation for many women.
• Sleep and stress are not side issues. Poor sleep worsens insulin resistance, and PCOS is associated with higher rates of anxiety and low mood, which in turn make lifestyle changes harder to sustain.
• Be sceptical of restrictive "PCOS diets". Highly restrictive plans circulating online are rarely sustainable and aren't better supported than a balanced pattern you can maintain long term. A dietitian can adapt guidance to what you actually eat rather than replacing it wholesale.

None of this replaces medical treatment where it's indicated — it works alongside it.

Common myths worth clearing up

• "PCOS means you can't get pregnant." PCOS is a common cause of ovulation-related fertility difficulty, not infertility. Many women with PCOS conceive naturally; others conceive with medical support.
• "Only women with a higher body weight get PCOS." PCOS occurs across the weight spectrum, including in lean women, who are sometimes diagnosed later because they don't fit the expected picture.
• "Cysts have to be removed." The follicles seen on ultrasound in PCOS are not the kind of cysts that require surgical removal.
• "Taking the pill cures PCOS." Hormonal contraception can manage symptoms such as irregular cycles and acne effectively, but symptoms typically return when it's stopped, because it manages rather than cures the underlying condition.
• "It goes away after marriage or childbirth." Neither changes the underlying condition. This is a persistent myth and it delays people seeking care.

PCOS, fertility, and long-term health

PCOS is one of the most common causes of ovulation-related fertility difficulty, but it does not mean infertility. Many people with PCOS conceive naturally, and others do so with medical support such as ovulation-inducing medication. Beyond fertility, unmanaged PCOS is also associated with a higher long-term risk of type 2 diabetes, high cholesterol, high blood pressure, and endometrial issues from infrequent periods — which is why ongoing monitoring matters even when you're not trying to conceive.

Managing PCOD/PCOS day to day

• Regular movement and balanced meals help manage insulin resistance, often the root driver of symptoms
• Even a 5 to 10 percent reduction in body weight can meaningfully improve symptoms for many people
• Doctors may prescribe hormonal birth control, anti-androgen medication, or insulin-sensitizing medication depending on your goals
• Regular follow-ups help catch related risks like diabetes or cholesterol changes early
• Mental health support matters too — PCOS is linked with higher rates of anxiety and low mood
