Is it normal to have irregular periods after 40? Yes, hormonal fluctuations during perimenopause can cause irregular cycles, lighter or heavier bleeding, and mood changes. But, if irregularities come with severe pain, fatigue, or heavy bleeding, consult a gynecologist. It could signal conditions like fibroids or thyroid imbalance. Regular health checks and tracking your cycle can help manage symptoms effectively. #hospital #NMC #healthcare #healthcare tips
