Hello, I am trying to determine if my issue is a OBGYN consult or an internal medicine consult. My symptoms are a dramatic weight gain (no change to diet, exercise moderately and take stairs at work), body acne (both front and back, but not face) and very light menstrual cycle continuously. I recently started a new job and thought the symptoms were related to the stress of that, however I have a multi nodular thyroid that I had ultra sounds and biopsy s done three years ago and now since the symptoms are continuing past a month, I am wondering if they are related to that or something else. All I know is something is not right and I need to consult either my OBGYN or an Internal medicine specialist. I am a female and 40 years old. Can you advise me of whom to contact regarding my symptoms?
