What causes heavy periods?

In some cases, the cause of heavy menstrual bleeding is unknown, but a number of conditions may cause menorrhagia. Common causes include Hormone imbalance. In a normal menstrual cycle, a balance between the hormones estrogen and progesterone regulates the buildup of the lining of the uterus (endometrium), which is shed during menstruation. If a hormone imbalance occurs, the endometrium develops in excess and eventually sheds by way of heavy menstrual bleeding.

There might be an underlying cause of your heavy bleeding, you can read more about the different causes on our main page. Before you start self-diagnose, make sure you make an appointment with you GP, when there can be a more serious cause.

How does Primolut-n work in treatment of heavy periods?

As mentioned above Primolut N contains norethisterone, which is a synthetic version of the naturally-occurring female sex hormone, progesterone. Norethisterone mimics the effects of your natural progesterone and so can help regulate the healthy growth and normal shedding of the womb lining.

When the body produces progesterone at certain times of the menstrual cycle, causing the womb lining to flourish. If a fertilised egg doesn’t attach to the womb lining by the end of the monthly menstrual cycle, the levels of progesterone in the body decrease. This causes the body to shed the womb lining (a menstrual ‘period’). If a fertilised egg successfully attaches to the womb lining by the end of the monthly cycle, progesterone levels in the body remain high.
