Query: Generalised Skin Darkening, Weigh
I am a 20-year-old woman with PCOS experiencing generalised skin darkening despite religious sunscreen use, approximately 10 kg weight gain after starting myo-inositol and D-chiro-inositol, recurring acne, skin texture changes, severe fatigue, weakness, brain fog, abdominal discomfort during running, and pelvic sensitivity. My thyroid, cortisol and CBC tests were reportedly normal. skin is a concern and I want oral medicine for that. My symptoms are affecting my daily functioning and quality of life. I need further investigation into the underlying cause and, importantly, assessment for appropriate oral medication rather than topical treatments alone. What investigations and treatment options would you recommend?

Skin darkening, particularly around the neck, underarms, or skin folds, can sometimes be associated with insulin resistance, which is commonly seen in PCOS. However, generalised skin darkening along with severe fatigue and weakness warrants further medical evaluation to rule out other hormonal, metabolic, or nutritional causes. I would recommend consulting an endocrinologist for a comprehensive assessment. Depending on your clinical history and examination, investigations may include fasting glucose, HbA1c, a lipid profile, vitamin B12, vitamin D, ferritin/iron studies, and other relevant hormonal or biochemical tests. Your doctor may also consider additional investigations based on the pattern of skin darkening and your other symptoms. Since you have experienced approximately 10 kg of weight gain after starting myo-inositol and D-chiro-inositol, please review the supplement, its dosage, and the timeline of your symptoms with your treating doctor. The association does not necessarily mean the supplement caused the weight gain. From a nutritional perspective, an individualised PCOS-friendly diet focusing on balanced meals, adequate protein and fibre, appropriate carbohydrate portions, regular physical activity as tolerated, and good sleep can help support metabolic health.
Health Tips
Please do not start oral medication for skin darkening without identifying the cause. Appropriate treatment depends on the diagnosis, and generalised skin darkening with significant fatigue deserves prompt medical attention.

Your symptoms warrant medical assessment to rule out insulin resistance and other causes of pigmentation, fatigue and weight gain. Alongside review by a doctor/dermatologist, a personalised nutritional assessment can help evaluate your diet, supplement use, energy balance and blood-sugar management. I’d be happy to support you with a tailored PCOS-focused nutrition plan rather than relying on topical treatment alone.

Oral treatment for this does exist, but choosing between options like spironolactone or a hormone-based pill depends on your actual androgen and insulin values, which your thyroid and cortisol tests alone don't show. The weight gain, acne and darkened, thicker skin you're describing are a textbook insulin-resistance pattern in PCOS rather than a reaction to the inositol supplements.
Next Steps
Ask for a fasting insulin, HOMA-IR and a free androgen or testosterone panel if these haven't been done. A gynaecologist or endocrinologist can then recommend the oral medicine that actually fits your results, rather than starting one blind.
Health Tips
Please see a gynaecologist or endocrinologist in person, and mention the pelvic sensitivity and discomfort during running too.
