She was 26 years old and had been told she had PCOS since she was 19. In those seven years she had seen four gynaecologists, been prescribed the contraceptive pill twice, and had been told to lose weight each time she attended a clinic. Nobody had ever explained to her why she could not lose the weight in the first place. Nobody had asked why a young woman with no family history of obesity had gained 24 kilograms between the ages of 17 and 26 despite eating less than everyone around her.
She arrived at my clinic with irregular periods, significant facial hair, acne along her jawline, and a level of exhaustion that had led her to leave her job six months earlier. She had been told these were the symptoms of PCOS. She had not been told they were the symptoms of a hormonal system in complete disarray, one in which the PCOS was not the origin of her problems but the visible expression of a much deeper biological failure.
When I reviewed her full hormonal profile the picture was comprehensive. Her fasting insulin was severely elevated. Her testosterone was high. Her LH to FSH ratio was disrupted. Her cortisol pattern was abnormal. Her leptin was elevated with clear signs of central resistance. This was not a gynaecological condition being managed inadequately. This was a complete endocrine collapse being treated as a single organ problem.
The PCOS was real. But it was downstream of the insulin resistance, which was downstream of the metabolic predisposition written into her biology from birth. The FTO gene's influence on insulin signalling and fat distribution in Pakistani women creates a pathway to PCOS that begins in adolescence and accelerates with every kilogram of visceral fat accumulated. By the time most Pakistani women reach a gynaecologist with a PCOS diagnosis, the hormonal cascade that produced it has been running for years.
We treated the insulin resistance first. Then the androgen excess. Then the cortisol dysregulation. Then the leptin pathway. We did not treat the PCOS. We treated the biology that was producing it.
Eleven months later her periods had regularised. Her testosterone had normalised. She had lost 19 kilograms. And she told me at her review that she felt, for the first time since adolescence, that her body was working with her rather than against her.
That is the difference between treating a diagnosis and treating a patient.
FAQs
Polycystic Ovarian Syndrome is an endocrine disorder characterised by elevated androgens, disrupted ovulation, and ovarian cyst formation. It is the most common hormonal disorder in women of reproductive age globally and significantly more prevalent in Pakistani women due to the intersection of genetic predisposition, insulin resistance, and visceral fat accumulation. The FTO gene's influence on insulin signalling creates a metabolic environment in which the ovaries are chronically overstimulated by excess insulin to produce testosterone, disrupting the hormonal cycle from its foundation. Dr. Zaar identifies PCOS as both a primary driver of obesity and a consequence of the same metabolic dysfunction that produces it.
Excess circulating insulin acts directly on the ovaries, stimulating them to overproduce androgens, particularly testosterone. This androgen excess suppresses ovulation, disrupts the menstrual cycle, and drives the cyst formation that defines PCOS. Simultaneously, high insulin promotes visceral fat accumulation, which generates further inflammatory cytokines that worsen hormonal disruption. In Pakistani women, this cascade begins earlier and at lower body weight thresholds than in Western populations. Dr. Zaar consistently finds that treating the insulin resistance resolves a significant proportion of PCOS symptoms, because the insulin pathway is the origin, not a bystander.
The FTO gene at Chromosome 16q12.2 influences insulin sensitivity, fat distribution, and hypothalamic hormonal regulation, all of which are directly implicated in PCOS pathophysiology. In Pakistani women, the FTO associated metabolic profile creates a predisposition to early onset insulin resistance that drives androgen excess from adolescence onward. This is why Pakistani girls frequently develop signs of PCOS, irregular periods, acne, facial hair, years before their weight becomes clinically significant. The weight gain that follows is not the cause of the PCOS. It is a consequence of the same underlying biological disruption that produced it.
The contraceptive pill suppresses androgen production and regulates the menstrual cycle hormonally, producing symptomatic relief without addressing the metabolic dysfunction driving the condition. When the pill is discontinued, symptoms invariably return because the insulin resistance, visceral inflammation, and FTO associated hormonal dysregulation that produced the PCOS remain entirely untreated. Pakistani women are frequently managed on the pill for years, during which their underlying metabolic condition worsens silently. By the time they present wanting to conceive, their fertility is compromised not by the PCOS alone but by a decade of unaddressed hormonal and metabolic dysfunction. THE CHROMOSOME protocol treats the origin, not the symptom.
PCOS is the leading cause of anovulatory infertility globally. In Pakistani women, obesity compounds this significantly, visceral fat increases oestrogen production through peripheral conversion, further suppressing ovulation. Elevated insulin impairs egg quality directly. Chronic inflammation disrupts implantation. The result is a fertility landscape that is far more compromised than PCOS alone would produce. Dr. Zaar's protocol addresses every layer of this fertility disruption simultaneously, insulin, androgen excess, inflammation, oestrogen balance, and cortisol, because restoring ovulation in the context of unaddressed metabolic dysfunction produces only partial and temporary results.
Chronic stress elevates cortisol, which worsens insulin resistance, increases androgen production from the adrenal glands, and promotes visceral fat accumulation, all of which directly worsen PCOS. In Pakistani women, the social and familial pressures surrounding marriage, fertility, and physical appearance create a chronic cortisol burden that intersects devastatingly with the existing hormonal dysregulation of PCOS. Elevated adrenal androgens add to ovarian androgen excess, creating a combined androgenic load that drives more severe symptoms, greater weight gain, and deeper metabolic disruption. THE CHROMOSOME protocol includes adrenal and cortisol assessment as a core component of every PCOS evaluation.
Because the biological barriers to fat loss in PCOS operate independently of caloric intake. High insulin blocks fat release from storage. Elevated androgens promote visceral fat accumulation specifically. Leptin resistance ensures the brain never receives a satiety signal. Low grade chronic inflammation suppresses metabolic rate. Each of these mechanisms operates simultaneously and none of them responds to dietary restriction alone. Pakistani women with PCOS are not failing their diets. Their diets are failing their biology. THE CHROMOSOME protocol dismantles each barrier in sequence, beginning with insulin, the master driver of the entire cascade.
Untreated PCOS in the context of ongoing obesity and insulin resistance creates a trajectory toward type 2 diabetes, cardiovascular disease, non alcoholic fatty liver disease, endometrial cancer, and severe fertility compromise. In Pakistani women, where PCOS is frequently undertreated and the metabolic environment continues to worsen across the reproductive years, these risks materialise earlier and more severely than global statistics suggest. Dr. Zaar treats PCOS not as a gynaecological inconvenience but as the early expression of a systemic metabolic disease that, left unaddressed, will define the patient's health trajectory for decades. The time to treat it comprehensively is now, not after the complications have arrived.
