Welcome to icliniq.com.
I just read your query.
You did not mention that have you been performed any test, ultrasound and the previously taken any allopathy medicine. Also, you have been taking this medicine for quite long. Is now your period regular or not? All the symptoms you have mentioned are signing towards PCOS (polycystic ovarian syndrome). In ayurveda, this disease is not described as a single disease, but a group of illness included in it. First of all due to stress, junk food and unhealthy lifestyle your body's circadian rhythm was disturbed. Circadian rhythm is a natural clock, which further leads to many problems and hormonal imbalance. The indigestion is mainly due to fast food and unhealthy eating habits because your body release certain enzymes and digestive juices to digest your food. Excessive junk food and not having food on time leads to improper digestion. According to ayurveda, this is called as agnimandya. Hair fall, acne, irregular periods and indigestion all are considered under PCOS. You have not mentioned about your height and weight. Because in PCOS sometimes weight also increases and insulin resistance also occurs, which leads to high blood glucose levels and obesity.
Start improving your lifestyle because your lifestyle plays a significant role in your health. Start doing yoga and meditation daily. In yoga, you can do asanas like Sarvangasana, Mathsyasana and Shavasana. Initially, you will face some difficulty in doing these postures, but with the passage of time your body flexibility will increase, and you will easily do them. You can take help from professional yoga trainer too. Do exercise daily and walk daily at least for 30 minutes. If you cannot exercise daily, then do brisk walk daily as this will help you to maintain weight. Exercise, yoga, and walk increase blood flow to the pelvic area, which is helpful in curing problems. Eat healthy and fresh fruit and try to split your three heavy meals into five small meals. Eat fresh fruits and green leafy vegetables more. Both of these are helpful in your problem as they are rich in fibers and antioxidants, which will help you a lot. Start taking soy products because these are also helpful inPCOS. Do not consume too much milk because some researchers show that too much milk also increases testosterone levels. Avoid junk food, tea and coffee as much as possible instead you can take green tea one to two cups if you want to take them. Try to have home made food as compared to outside food as this will have an excess of spices. Since you have been taking this treatment for so long and any treatment whether it is Ayurveda or allopathy should be changed after some time. So here I am suggesting you the treatment.
Take Chitrakadi Vati (Chitraka, Maricha, Pippali, Pippalimoola) one tablet twice a day after food with lukewarm water for four weeks. It will help to control your indigestion. Take Varunadi kwath (Sahachara, Sathaavari, Agni, Murva) 2 teaspoons with an equal amount of water two times a day for four weeks. It will contribute to normalizing your irregular periods. Take Arogyavardhini Vati (Shuddha Parada, Shuddha Gandhak, Loha Bhasma) one tablet twice a day with lukewarm water. It will help to control your acne and improves your menstrual cycle too. You can continue Kumaryasavam for one more month as it is also helpful to your condition. If you pass stool once or twice a day and do not have any other problems like a pain in the abdomen or anemia, then it is fine. The black-colored stool has many causes. Sometimes, it is due to some medications and dietary things, and sometimes, a disease too. You can go for a stool examination. If it is normal, then do not worry about color and other things.
For irregular sleep, I already mentioned about yoga and meditation. Both of these will help in calming mind and body. Also, go to your bed before midnight whether you feel sleepy or not and switch off the lights. After some days your body will find it easy to fall asleep. Try to avoid your contact with the mobile phone, laptop and television one hour before sleep, as blue light of all these hinder regular sleep pattern. Do perform some blood tests like testosterone, FSH (follicle-stimulating hormone), LH (luteinizing hormone), blood glucose level and ultrasound. Try all these things regularly, and you will see positive results very soon. Revert to me after blood reports and ultrasound.
