Why the name changed
The follicles seen in many patients are not the same as pathological ovarian cysts, and an ultrasound is not required in every case. The newer name emphasizes that the condition can affect multiple hormones, metabolism, menstrual and reproductive health, skin, hair and psychological well-being.
Why PCOS/PMOS is linked with insulin resistance
Insulin resistance means muscle, fat and liver cells do not respond to insulin as effectively as they should. The pancreas may compensate by producing more insulin. Higher insulin levels can stimulate ovarian androgen production and lower sex hormone-binding globulin, increasing active androgen exposure. This helps explain why metabolic and androgen-related symptoms can occur together.
Not every person with PCOS/PMOS has obesity or measurable insulin resistance, and the syndrome can occur at any body size. However, abdominal adiposity and insulin resistance can amplify one another and increase risk of prediabetes, type 2 diabetes, abnormal lipids, high blood pressure and fatty liver.
Why weight gain may occur
PCOS/PMOS does not break the laws of energy balance, but insulin resistance, appetite biology, sleep problems, mood, medicines and reduced activity may make weight management more difficult. Weight gain can then worsen insulin resistance and androgen-related symptoms, creating a cycle that deserves medical treatment rather than blame.
Why scalp hair may thin while facial hair increases
Androgen sensitivity can miniaturize scalp hair follicles in a female-pattern distribution while promoting thicker facial or body hair. Iron deficiency, thyroid disease, recent illness, rapid weight loss and scalp disease may coexist, so not every hair symptom should automatically be attributed to PCOS/PMOS.
How PCOS/PMOS is assessed
Assessment considers menstrual or ovulatory dysfunction, clinical or biochemical androgen excess and ovarian morphology when appropriate, while excluding other causes. The exact diagnostic approach depends on age and clinical context. Ultrasound alone cannot establish the diagnosis, and adolescents require particular caution to avoid overdiagnosis.
What longer-term metabolic review may include
- Glucose assessment and diabetes risk
- Blood pressure and lipid profile
- Weight, waist distribution and sleep apnoea risk
- Fatty liver and other metabolic complications when clinically indicated
- Mental health, body image and eating-disorder symptoms
Treatment is matched to the patient’s priority
The immediate goal may be cycle regulation, acne or hair symptoms, metabolic health, weight treatment or pregnancy. Management can include lifestyle support, treatment of metabolic risks and selected medicines, with gynaecology, fertility or dermatology coordination when needed. One medicine cannot solve every part of the syndrome.
Why patients consult Dr. Fowad
Dr. Fowad’s board-certified work in Obesity Medicine and his clinical focus in diabetes and metabolic health are especially relevant when PCOS/PMOS overlaps with insulin resistance, weight gain, fatty liver, prediabetes or cholesterol concerns. Appointments are available in DHA Phase 6 and Garden Town, Lahore, and in Gujranwala.
