Thanks for an elucidated query. You are 128 kg, meaning you are obese (overweight). This along with your menstrual cycle problem suggests that you have hormonal problems. I would suggest you :Hormonal assay- T3, T4, TSH, FSH, LH, Estrogen, Progesterone and Testosterone estimations. Ultrasonography and color Doppler for ovaries and genitourinary tract. Stop all the medicines and wait till the reports are available. Once the proper evaluation will be done the treatment will be specific according to the cause. The most important for you is to reduce your weight to the normal. Most of the problems will be solved on its own. You can consult a Team of dietitian, physiotherapist and bariatric surgeon who are dealing with obesity. This will help you the most. </s>
