<s>[INST] Hello doctor, I am a 23 year old female. I weigh 49 kg. My height is 140 cm and my BMI is 25. I am getting married in a few months and need to shed a few pounds. I took Orlistat 60 mg capsules after breakfast and lunch. I bought it over the counter without a prescription. The same evening, I had constipation. I drank a lot of water and was fine at night. The next morning I passed an oily stool. I also noticed small spots of bleeding from my vagina. I had my previous periods 15 days back which lasted for four days. I also have a problem ofPCOS (Polycystic Ovary Syndrome). I am scared if this tablet will affect my health. Please suggest if I should continue with Orlistat. Or can you recommend any other diet pills for weight loss? [/INST] Hello. You need not take this drug to reduce weight. I would recommend you to stop this drug. An oily stool is normal with the medication you had taken. If you are already a diagnosed case of PCOS, consult a gynaecologist online and get it treated. PCOS is a cause for overweight. This might also cause unwanted facial hair, infertility etc., later in life. Since you are getting married, it is very important that you get this disease treated at the earliest. The vaginal bleeding needs clinical examination. An ultrasound scan has to be done and treated accordingly. Modify your diet if you are very particular about reducing weight. Cut down fats, sugars, oil, alcohol if any, non-vegetarian food, etc. Take a lot of fresh fruits, fresh juices, salads, soups, and green vegetables. Drink plenty of water. Gradually start brisk walking, exercise, yoga, pranayama, dance etc. For further information consult an obstetrician and gynaecologist online --> </s>
