Hi. This is a question for my mother who is 43 years old. From the last 3 days, I've seen her feel dizzy and collapse twice. I'm trying to figure out what is the issue here? She's also been complaining of heavy blood flow during her periods, the cycle being faster and quicker (she gets it every 20-25 days) and the dizziness crops up just around that time. Also, she's been feeling quite fatigue these days. Could this be like a warning sign or something? I'm very skeptical of taking her to a hospital at this time. Please suggest which doctor can look into this.
