PCOD vs. PCOS-Key Differences

Introduction

Polycystic ovarian syndrome (PCOS) and polycystic ovarian disease (PCOD) are conditions that affect female reproductive health, particularly the ovaries. The function of the ovaries is to release an egg each month and produce the hormones oestrogen and progesterone. PCOS and PCOD are frequently confused to be the same condition, as both of them impact the ovaries with egg development problems and hormonal imbalance. But these are two distinct conditions, as the cause, severity and impact differ from one another. Understanding the difference between these two conditions is essential for accurate diagnosis and treatment.

This article aims to clarify the key differences between PCOS and PCOD, their causes, symptoms and management strategies.

PCOD

In a menstrual cycle, the two ovaries take turns to release mature and fertile eggs. In PCOD, hormonal imbalance causes the ovaries to release eggs that are either not mature or those that are not completely mature[8], which, over time, form cysts (fluid-filled sacs). The ovaries swell up and become enlarged. During a normal menstrual cycle, the ovaries release male hormones (androgens) in small quantities. However, in PCOD, ovaries produce excess androgens, causing the following symptoms:

• Male pattern hair thinning
• Irregular periods[9]
• Acne
• Oily skin
• Excess weight around the abdominal area

PCOS

PCOS, in addition to being a hormonal condition, is a metabolic disorder as well. Thus, it not only affects the ovaries but also other body systems. PCOS also involves excess androgen production, which hampers egg development and release, with the eggs being prone to turn into cysts. PCOS shares some common symptoms with PCOD, such as weight gain, irregular periods, acne and hair loss[10].

PCOS is accompanied by these additional symptoms:

• Missed or absent periods
• Excess hair growth on body and face
• Darkening of the skin under the breast and around the neck
• Severe acne
• Increased risk of diabetes and heart disease[11]
• Sleep apnea (breathing is affected during sleep) causes disturbed sleep
• As ovulation does not occur, the uterine lining thickens, increasing the risk of endometrial cancer.

Differences between PCOS and PCOD

Factor	PCOD	PCOS
Prevalence	PCOD is more common than PCOS. Globally, the prevalence of PCOD is approximately 10%	that of PCOS is 0.2% to 2.5%.
Cause	Reduced levels of FSH do not promote the maturation of ovarian follicles, thereby releasing immature eggs.	The levels of LH are elevated, causing excess androgen production and preventing the conversion of androgen to oestrogen. Some other factors that are responsible for PCOS include environmental factors, family history, insulin resistance and thyroid problems.
Age of onset	More common in adolescents.	More common in women in their 20s or 30s.
Ovarian cysts	The cysts are fewer in number and smaller in size. PCOD cysts can be resolved with lifestyle modifications.	The cysts are larger in number and size. PCOS cysts require medical intervention.
Hormonal imbalance	Mild	Significant
Menstrual cycle	Periods may be delayed or slightly irregular	Periods are highly irregular or are completely absent.
Ovulation	The ovaries release eggs irregularly	Ovulation is either severely reduced or completely absent.
Fertility	Does not impact fertility, and women do not encounter any conception problems. Very rarely, women may require some fertility drugs to aid conception.	Severely impacts fertility, making conception difficult.
Weight gain	Weight gain is present but can be managed via lifestyle modifications.	Significant weight gain: women struggle with weight loss owing to insulin resistance.
Hair growth and acne	mild acne, oily skin and infrequent hair thinning	severe acne, hair growth on face and body and significant balding
Emotions	mild mood swings and stress due to irregular periods.	anxiety, depression and low self-esteem
Long-term health complications	negligible risk for chronic conditions with proper management	Requires long-term medical management as there is increased risk of chronic conditions, such as diabetes, heart disease, infertility and some cancers (endometrial cancer).
Reversibility	Symptoms can be reversed with lifestyle modification.	Long-term medical treatment is required for effective symptom management.

Diagnosis

Gynaecologists diagnose both conditions by collecting medical history and assessing the symptoms experienced. They may also order blood tests to check for hormone levels and an ultrasound to check the ovaries for cysts.

PCOD: Slightly enlarged ovaries with immature follicles

PCOS: For PCOS diagnosis, at least two of the three criteria of the Rotterdam criteria for PCOS diagnosis must be met, which are as follows: 1. Irregular periods, 2. Excess androgen production and 3. Ovarian cysts

Treatment

PCOD: Lifestyle modifications help in symptom management.

• Manage stress with meditation or yoga (reduces cortisol levels).
• Physical activity and a healthy diet (low glycaemic index foods [unlike high glycaemic index foods, there is a gradual increase in blood sugar levels] and protein- and fibre-rich diet) to maintain a healthy weight and sugar levels and reduce insulin resistance.
• A dermatologist consultation can usually resolve acne and hair problems.
• Very rarely, medications are prescribed to address hormonal imbalances.

PCOS: Long-term medical management is required.

• Oral contraceptives containing oestrogen and progestin (mimics progesterone) are prescribed to regulate the menstrual cycle
• Metformin for improving insulin resistance
• Fertility treatments to aid conception[14]
• Lifestyle modifications and stress management (as for PCOD).

 

 

Conclusion

Understanding the difference between PCOS and PCOD is crucial for early diagnosis and treatment. PCOD is a milder condition compared to PCOS, and lifestyle modifications will suffice to manage the symptoms. In contrast, PCOS is a complex hormonal disorder and requires long-term monitoring to prevent complications, such as infertility, diabetes and heart disease. Speak to your gynaecologist if you have any confusion about your symptoms[15] to get the right treatment at the earliest.
