	Answer by Dr Noopur S, MD (doctor) on Mon 05, Jan 2009 11:56pm: Hi, Thanks for writing in. Thyroid problems are one of the most frequent causes of irregular menstrual cycle in women. Infrequent or sporadic periods are seen in hyperthyroidism. I would suggest you to see an endocrinologist and get treated for thyroid dysfunction. Other causes include large amount of weight loss or weight gain, premature ovarian failure, anorexia nervosa, Cushings disease and medications like Phenothiazines. Please discuss all these causes with your treating doctor and let us know if you need more information. Take care!
