Hello and welcome to HCM . Stretch marks develop due to quick weight gain followed by weight loss .There is no remedy that will make them go but massaging with vitamin E creams helps in improving the appearance and texture of the skin . Weight loss should be gradual and along with Homoeopathic medicines she should also start eating small light (non oily ) meals every 2 hours .So she should consume lost of fruits , vegetables, curd/yogurt , soups etc in small quantities every few hours . Sweets /chocolates and sugar to be completely avoided . This will help in trimming the belly fat as well as not allow distension of the abdomen any further . At least 30 minutes of regular exercise like brisk walk or cycling or Yoga will help in toning up the muscles and help lose fat faster . She can take Podophyllum 30 4 pills three times daily for one month along with the above suggested measures . To gain back the previous figure is going to need lot of effort because it is also about gaining back the muscle tone which takes at least 3-6 months .So be patient and persevere in your efforts . Hope this helps , Good Luck .
